Do-it-yourself repair of a Redmond multicooker: the thermal fuse does not turn on, Redmond malfunctions, do-it-yourself repair of a Redmond multicooker does not work

At the dawn of the 21st century, a new household multifunctional electrical appliance for cooking with program control called a Multicooker

. Despite its modest appearance, in a multicooker you can fry, steam, boil, bake, stew, reheat and keep food hot in automatic mode.

I came across a faulty multicooker with a broken lid and an error code on the E1 display. Due to the lack of a PN8024R power supply chip, a non-standard repair method had to be used.

Choosing detergents

During the cooking process, various food particles often get into the interior of an electrical appliance.
Some housewives, in a hurry to prepare lunch or dinner, violate the rules for the sequence of placing food in a multicooker: they place food in the bowl without first removing it. To clean the unit, it is unacceptable to use hard sponges and abrasive detergents, as they can easily damage the internal and external parts of the device.

The best option for removing contaminants from the surfaces of the device are mild chemicals and home remedies.

Household

Care kit for Zumman multicookers - the German product kit includes a liquid cleaning agent, wet wipes with varying degrees of lint hardness on the front and back sides. With the help of napkins, you can quickly and effectively remove dirt from any surfaces of the device; in case of significant accumulation of plaque on the elements of the unit, use the product in the form of a liquid.
Top House is a gel designed for the care of household appliances used for cooking and non-stick cookware. To remove grease stains from a multicooker, apply a small amount of gel to a sponge, foam it and treat the contaminated surfaces, then remove the remaining product with a damp cloth and rinse the device.
Sanita spray “1 minute” is a domestic product that can effectively remove stubborn grease deposits and is suitable for cleaning various types of surfaces. After spraying the drug onto contaminated areas, wait 1-2 minutes and wipe the treated areas with a damp cloth, then rinse with water.

Folk

In some cases, the use of household chemicals is not suitable for caring for an electrical appliance: for example, a person experiences an allergic reaction upon contact with a certain product.

After using ready-made preparations for cleaning surfaces that will then come into contact with food, the treated containers must be washed several times in clean water. If the rinsing procedure is not carried out thoroughly, the remaining chemical particles can have a negative effect on the living organism.

Citric acid perfectly cleans the microwave from grease.

It should be said that most available products have no less cleaning effect than special preparations:

pour 25 g of citric acid into 200 ml of warm water, stir the ingredients;
pour the solution into the bowl of the electrical device and turn on the steam cooking mode for 15 minutes, then drain the liquid, rinse the tank and wipe it dry.

Lemon will help get rid of plaque and eliminate unpleasant odors: pour a glass of water into the bowl and place half a citrus fruit there. As with citric acid, turn on the device in steam mode for a quarter of an hour. After the time has passed, drain the liquid and wash the tank in running water and dry it.

Internet of Things REDMOND

The Ready for Sky app allows you to control all REDMOND Smart Home appliances

In 2014, REDMOND multicookers began to have remote program launch and control based on a single technological platform - an application for iOS and Android from the Singaporean company Ready for Sky (R4S).

Since the distributed distribution system involves a huge number of models and modifications of devices, it turned out to be unprofitable to produce individual smart devices and developers focused on a common cloud service for everyone.

The Russian market became the pilot market for the launch of the entire line of smart appliances REDMOND Smart Home. Smart home devices have received a good response, despite the stereotype about the conservatism of the Russian consumer.

The future of REDMOND looks innovative.

However, several countries were considered as such pilot markets for the project, and despite the difficult economic situation at that moment, the decision was made in favor of Russia, where the brand has gained wide popularity among consumers and has long been perceived as one of its own.

The support and willingness of consumers in Russia to provide constructive feedback on the ease of use of technology helps improve smart solutions.

Currently, about 70 different types of REDMOND smart household appliances are sold on the Russian market. The line includes smart sockets, climate control equipment (heaters, humidifiers, fans), water heaters, irons and the entire range of existing cooking equipment (from grills to ovens). A full range of gadgets for all tasks.

One REDMOND service combines a wide variety of equipment.

In Russia, new features are being introduced first (SkyMarket, SkyManager, voice control), and the right choice in favor of the CIS is supported by sales: more than half a million smart kettles and lamps alone have been sold.

All equipment for the CIS is developed and tested in the Russian REDMOND LABoratorium, undergoing detailed testing of the compatibility of any combination of components. This allows you to quickly identify and eliminate possible local bugs that abound in transnational smart home platforms.

Thermal fuse

The above-mentioned device, for which they asked for 5,000 rubles to repair, suffered from a common disease. The self-taught master opened the multicooker body, poured out the porridge, got to the thermal fuse, and replaced it. Then, having assembled the device, he gave it to the owner.

What is a thermal fuse. When it comes to repairing a multicooker, we are talking about a cylindrical piece of wire that strongly resembles a resistor in appearance. The operating temperature is 170 ºС, the maximum current is 10 - 15 A, depending on the type of element. When these parameters fall outside the permissible range, the thermal fuse burns, breaking the electrical circuit in which it is connected.

Why can't you make this item yourself? Firstly, the cost of the element is modest, and secondly, they installed a thermal fuse for a reason. A homemade copy has different characteristics, which will not lead to good things. Repairing a multicooker at home using such amateur activities will, in the worst case, end in a fire.

How to care for a multicooker

Although modern multicookers are made with the latest technology, they still require certain care and adherence to operating rules. If they are carefully observed, the kitchen appliance will serve you for a very long time, while delighting you with consistently high-quality dishes.

After each cooking, you must thoroughly clean the inside of the multicooker. Try to do this right away, without waiting for leftover food to stick to the sides of the bowl. Otherwise, you will have to use rough brushes and graters to wash dishes, damaging the walls of the multicooker;
During cooking, never cover the multicooker with towels to retain heat. The device can independently maintain the required temperature, but the greenhouse effect can negatively affect the electrical part of the multi-harvester;
The multicooker cleaner should not contain large or solid particles. Harsh chemicals are not suitable either. It is also better to put metal sponges and graters in the far corner, giving preference to creamy and foamy textures in combination with warm water;
do not leave the finished dish inside the bowl. It is better to place food in a special container or large plate immediately after it is ready to eat;
the use of metal spoons and ladles (when stirring or laying out food) leads to the formation of scratches and cracks on the inner surface of the multicooker. It is best to use silicone or wooden spatulas, which will not damage the delicate materials from which modern multicookers are made;
Monitor the condition of the exhaust valve. Unnoticed by you, it can become clogged, seriously affecting the thermoregulation process inside the device;
If water gets into the body or core of the electric base of the multicooker, immediately turn off the power to the device and do not turn it on until it is completely dry.

The best (and safest) means for cleaning a multicooker is water. Just hold the cup of the device under running warm water and it will shine like new again. For example, food processors repel grease and can be easily washed with a soft sponge (without any detergents).

But if the inner surface of the appliance is covered with a layer of fat or you still left the multicooker with food for a long time and now the stuck food particles need to be removed.

The following cleaning agents can be used for the multicooker:

gels and foams for kitchen appliances;
pH neutral dishwashing detergent;
impregnated kitchen napkins (especially for wiping tables and other surfaces);
soap solution (rub half the soap into warm water and shake until completely dissolved).

As an exception, food particles may get on it during the cooking process, but they can be removed immediately using any kitchen towel.

To maintain a “presentable” appearance, wash the multicooker with a sponge dipped in a mild soap solution (once every two weeks).

If “escaped” lunch gets on the inner or outer walls of the multicooker, soak a rag in hot water and wipe the contaminated area.

There are certain points, the observance of which guarantees the uninterrupted operation of the device for a long time:

You should wash the bowl from the multicooker regularly, after each cooking, not forgetting to also empty the moisture collector. Cleaning and washing at intervals of 1-2 times a month or as it gets dirty should include cleaning the heating element, lid, and walls.
During cooking, do not cover the appliance with a towel or other object to retain heat. This may negatively affect his work.
It is not recommended to leave the cooked dish in the bowl; it is better to transfer it to another bowl.
When cooking, try not to use metal kitchen utensils to avoid small scratches inside the appliance. It is better to give preference to wooden or silicone spatulas and spoons.
Impregnated kitchen napkins, liquid dishwashing detergent, soap solution, and baking soda will help you clean the multicooker. Wiping materials should be soft, for example, microfiber.
All work on cleaning equipment must be carried out after it is disconnected from the network and has completely cooled down.
To remove grease from the walls of the multicooker, inside and outside, do not use hard brushes or cleaning agents containing abrasives.

Appliance cover

Today we will tell you how to repair the Redmond multicooker. We will try to fix the lid with our own hands.

This is a standard breakdown for most types of multicookers. Damage to this cover is due to planned aging, that is, the manufacturer deliberately makes it unreliable. The finger on the button broke... The lid moved as a result of the temperature... The rods reach special grooves and the lid is inserted, but a few millimeters are missing...

We will need small magnets and will make a magnetic lid that closes, is held on by magnets and is opened under force. You need to glue 4 magnets - two on the lid and on the body of the multicooker itself. The multicooker bowl is pre-removable.

We select the points where we will glue the magnets. Degrease the surface with alcohol. First, apply high-quality glue to selected points on the body and press the magnets. Let's wait until the glue dries. Now, not forgetting to respect the poles of the magnets, glue them to the lid. In this case, it is more convenient to apply glue directly to the magnet. If there is a need and the height of the magnets is insufficient, you need to glue two magnets on top of each other. Here we are already acting empirically.

This, of course, is not the most common way to solve the problem of a broken multicooker lid latch. Basically, experts solve it by replacing the handle, if the mounting points are not damaged, but the handle itself is broken. Or, as an alternative, drill holes in the handle and fix it with screws. The choice is yours.

What to look for when choosing?

Which one to choose? When choosing a multicooker, experts recommend paying attention to the following points:

power. Models with high power are able to cook the desired dish in half the time. Therefore, in order to save time, it is worth considering devices with a power of 700 W or more;
bowl volume. The best option is considered to be a device with a 5 liter bowl, which is quite enough for a family of 4 people. If the family is large, it is better to purchase a model with a larger bowl;
number of programs. A device with a large number of programs will cost more, however, the cooking process will be significantly simplified.

E2

Error E2 on the Redmond multicooker - open or short circuit of the upper heat sensor. This is an error that occurs due to burnt-out thermostats under the bowl and lid of the multicooker. If this error occurs, you must first check the device with an ohmmeter or multimeter.

Reasons E2

The main causes of the error are a break in the connecting cable, which occurs due to mechanical damage due to careless handling or the multicooker falling from a height. In this case, connecting individual parts of the cable will not have any effect and the device will not turn on.

Sometimes the appearance of an E2 error while the multicooker is operating may simply be a system failure, and not a signal of a breakdown. Before you begin to solve the problem, you need to turn off the device from the network and turn it on again after 5-10 minutes, allowing it to cool.

Also, the cause of the problem may be that cereals, salt or sugar get under the multicooker bowl, which clogs the device and causes overheating. In addition, a short circuit may occur in the temperature sensor, which is located in the lid of the device.

Elimination E2

If solid bulk products get between the bowl and the heating element, the contact between the heat sensor and the container will significantly deteriorate. To fix the problem, you need to disconnect the multicooker from the mains and carefully remove the bowl from the device body. Next, you need to inspect the bottom of the device and remove dirt.

If the cause of the breakdown is a short circuit, you should clean the terminals of the thermocouple - the sensor responsible for measuring temperature. To do this you need:

Turn off the device and remove the bowl from it.
Unscrew the bottom cover and find the thermocouple, which is located in the center of the base of the multicooker.
Press the top plate on the side of the adjustment screw until you hear a click.
Carefully clean the terminals with sandpaper and reassemble the device in reverse order.

When you turn it on again, the multicooker should start without problems, and the error code will no longer appear on the display.

If the multicooker starts but does not work, the problem is a broken connecting cable. You can check this by connecting another working cable (some models come with a spare cable). If the device works normally when you connect it, then you need to replace the cord with a new one.

You can also recognize an open circuit inside the device using an ohmmeter - using the wire that connects the sensor and the display.

To solve the problem of a faulty upper temperature sensor, you must first conduct a thorough inspection of the wires that connect the sensor to the controls. If the cover is opened frequently, thin cables may break or become deformed, requiring complete replacement.

The insulation on the wires that connect to the sensor often melts when exposed to high temperatures. You need to pay attention to its integrity when inspecting the temperature sensor.

The multicooker has stopped working and won’t turn on anymore - reasons and DIY repairs

Before blaming the manufacturer for a breakdown, it is worth analyzing the situation. Perhaps you simply do not know all the intricacies of the device. It is also necessary to remember what happened the last time it was turned on.

Possible reasons

So, you've taken your new slow cooker out of the box, loaded it with groceries, and are trying to start it up. But for some reason she doesn’t want to turn on. Fixing the problem in this case is not difficult: most likely, you just installed the bowl incorrectly or overloaded it with products above the division (see photo). The container must be removed and reinstalled. It is also necessary to check the degree of loading of the device.

A similar problem can also occur when:

incorrectly set cooking mode: each type of dish requires a certain temperature; if it is violated, overheating protection is triggered;

excessive loading of products above the level of divisions located in the upper part of the bowl and, as a result, excess boiling liquid entering the heating element;

Loading the multicooker above the level of the last mark is unacceptable

lack of liquid: in this case the bowl overheats, the sensor immediately triggers and turns off the device;

low voltage or lack of electricity;
Contacts become dirty when pieces of food get in: they need to be cleaned;
the pressure valve built into the multicooker lid is clogged: in this case, it is enough to simply rinse it;
deformation of the bowl: this defect is clearly visible even externally;
factory defective temperature sensor: the last two problems are rare, but they can still happen.

Defects such as a burnt microcircuit or failure of a temperature sensor are less common. In this case, you will not be able to figure it out yourself without special knowledge - you will need to contact a service center.

After selecting the cooking mode, do not forget to press the “Start” button

Correct operation

Often users feel that the multicooker turns off prematurely. The reason for this very often lies only in violation of operating rules. Thus, interruption of heating before the set time can occur when:

contact with the heating element of bulk products or moisture;

The heating element must not be exposed to moisture or food particles.

incorrectly set cooking temperature for this product; in this case, the built-in overheating protection may also trigger;
burning of the bottom of the bowl;
exceeding the set temperature due to a clogged pressure valve located in the multicooker lid (it must be removed and cleaned);
factory defect of the temperature sensor: such a problem occurs infrequently, but it is quite possible;
a defect in the bowl, due to which food gets onto the heating element.

In order for the multicooker to serve for a long time, it is worth remembering the basic rules of its operation:

place it on a flat, hard surface;
connect the device to a working outlet with grounding;
Before turning on, make sure that the lid is closed tightly;
after washing the bowl, it must be dried or wiped dry; It is prohibited to place wet dishes on the multicooker stove;

The pressure valve located in the lid of the device is also not simply wiped with a dry cloth, but washed thoroughly.

The steam valve built into the lid requires mandatory cleaning

E1

Error E1 for the Redmond multicooker - a break in the lower temperature sensor or overheating of the device. An error code appears on the display if there is a problem with the temperature sensor or if the central heating mechanism overheats. If the cause is eliminated in time, this failure rarely leads to serious damage.

Reasons E1

Error code E1 indicates a problem with the temperature control mechanism. Several factors can lead to this problem:

food debris and solid grains getting between the bottom and the multicooker bowl;
moisture entering the heating sensor;
heating sensor overheating;
random software glitch.

In this case, the temperature sensor can operate stably, but the display will display information about emergency mode.

Elimination E1

If an error code appears on the device display at the very beginning of operation, this may indicate a system failure. Simply reboot the device. To do this, you need to completely turn off the multicooker by unplugging the plug from the outlet. Then let the device cool down, leaving it for 10-15 minutes.

It is worth rebooting the device first of all if an E1 failure appears on the display of a completely new multicooker that has been running for one or two days.

If the error appears on a device that has been in use for a long time, the likelihood of a system problem is significantly reduced. Then you may need to disassemble the device:

Turn off the device and let it cool down.
Remove the bowl from the housing and make sure that there are no remaining moisture or foreign substances on its surface.
Unfasten the bottom of the multicooker and find the thermocouple in the very center of the base.
Press the top plate on the side of the adjusting screw until it clicks.
Clean the terminals using fine-grit sandpaper.
Reinstall the components and turn on the device again.

To prevent moisture and food particles from entering the interior, rinse the appliance thoroughly after each use, wiping the bowl and lid dry.

Features and appearance of the model

Note! The manufacturer of the multicooker positions this model as a device designed to help parents of small children. The 2-liter bowl allows you to cook in small portions, which means mom can always prepare fresh and healthy meals for her baby.

Features of Redmond multicookers

The Redmond brand was founded by Israeli-Canadian-American investors in 2006. The Russian representative office and exclusive distributor of products is the company Tehnopoisk. The company produces small household appliances and exports them to the CIS, Europe, Turkey, India, USA, and Israel. All models are assembled at Turkish and Chinese factories.

Interesting to know! The official brand store in Russia is multivarka.pro, the international online platform is multicooker.com.

General characteristics of the model range

Multicookers from the Redmond brand have gained popularity among Russian users due to their affordable price, convenient functions and the presence of a recipe book. Among the features of the technology:

equipped with a removable non-stick bowl with a volume of 5 liters or more;
a sufficient number of automatic programs for a varied menu (popular ones include soup, frying, stewing, rice, pilaf, buckwheat, baking, steaming);
liquid crystal display for control with commands in Russian;
indicator mode for all household appliances;
weight about 4 kg;
cooking speed - from 5 minutes to 2 hours;
Availability of a delay start option.

All models are characterized by multifunctionality. Even inexperienced users can master their programs.

Design and principle of operation of a multicooker

The multifunctionality of the multicooker is ensured by the operation of a microprocessor system. It includes:

Electrical circuit and device (voltage is supplied to a connector with three contacts, the first grounds the device, the second is connected to the body, the third to the multicooker lid).
Wiring diagram (power is supplied through wires through which current flows to a series-connected switch and thermal fuse. The switch starts or turns off the multicooker, and the fuse protects the device from overheating).
Power supply (implements two functions: supplying an alternating voltage of 220 volts and converting it into a direct voltage of 5 volts for the control unit and 12 volts for the switching circuit. A battery (3 volts) is built into the power circuit; it carries information about the actions of the cook who starts multicooker action programs).
Control unit (all functions and programs of the device are generated by this circuit).
Thermistors (there are two of them: one is attached to the lid, and the second is fixed on the bottom of the multicooker. The main function of the resistors is thermoregulation in the operation of the device, so that the temperature is the same as in the program set by the cook).
Thermal fuse (protects the kitchen device from overheating and failure of the control system).

Preparatory work includes:

disconnecting the multicooker from the network - the device must cool down;
Next, you should open and wipe the lid, remove grease and deposits (using dishwashing detergents);
Wipe the lid dry.

Procedure for parsing:

open the multicooker lid;
press on the two plastic latches on the lid and pull them in the middle;
the upper sector is pulled towards itself, and then, with a sharp movement, down;
The internal parts are washed and food residues are removed from their surface.

To get to the internal circuits and parts of the multicooker, you need to:

remove dirt, plaque and grease from the surface;
turn the device upside down;
unscrew the screw securing the bottom of the device and disconnect the lower part of the multicooker from the base;
disconnect the wires;
unscrew the heating device;
disconnect the microcircuits;
disconnect the top cover and temperature sensors;
remove the rings and open the latches on the device body;
separate the inner walls from the outer ones.

All work should be carried out carefully and consistently so as not to break the multicooker parts.

Lifehacks from a specialist

Has your multicooker ever had errors?

It happened, it didn't happen

Often, service center employees find and fix problems with multicookers in 3-5 minutes, and the client will need to pay for their services in full. Before you say goodbye to a thousand or two rubles, you need to try to understand for yourself what is wrong and why this could happen.

Experts share tips:

Be sure to dry the bottom of the multicooker with a cold hairdryer - often housewives add water carelessly and it ends up outside the bowl. We turn off the network, remove the bowl, take a hairdryer. Select the “cold wind” mode (cool, cold). Place the multicooker on its side and dry it for 3-5 minutes, gradually rotating it in a circle.
Turn the device upside down - this procedure literally shocks many. The lower part contains special secrets in the form of treasures from leftover food, salt, and cereals. At least a tablespoon of garbage accumulates during a year of using the device, which causes blockages and malfunctions of boards and sensors.
Give it a rest - if the multicooker works from morning until late at night, you need to have a conscience and give it a little rest. Turn it off for 3-4 hours, after which many problems will resolve themselves.

The most important factor is following the manufacturer's recommendations. The mentality of the Russian people is such that they pick up the instruction manual when the device has already broken down. It is easier to prevent any problem than to solve it.

Multicooker "Redmond RMC-M22"

Malfunction: there is no indication, the multicooker does not respond to control buttons. Let's start disassembling and try to repair multicookers with our own hands. After unscrewing the screws on the bottom, disconnect the lower part of the stand from the base. We get access to the power supply, switching circuit and several functional elements. Unscrew the 4 screws of the power board.

We inspect the transformer for the presence of solder joints and tracks. We test the transformer windings with a multimeter. If the transformer is broken, replace the thermal fuse after unsoldering it. We call diode bridges, transistor. We replace elements and parts when breaks are detected.

Another option for repairing multicookers with your own hands with a “won’t turn on” fault, which generates an alphanumeric error code. Deciphering the codes allows a technician who knows them to understand the cause of the malfunction and begin to eliminate it.

For example, the code “e0-e4” displayed on the screen indicates malfunctions associated with short circuits and breaks in temperature sensors. They are located on the top or bottom of the multicooker. There may be a problem with thermal fuses, we have already discussed them above. Different manufacturers have their own codes. It is necessary to remove the multicooker body and use a multimeter to look for an open circuit, measuring the level of resistance. Then eliminate the detected breaks by replacing or repairing the necessary elements.

Instructions for repairing the device at home

In most cases, you can figure out why the multicooker refuses to work yourself. But, before you start analyzing it, you should pay attention to the error code displayed on the display. A detailed list of such codes must be in the instructions. Studying them will allow you to significantly save time and nerves - the manufacturer always indicates ways to eliminate each of these errors.

For example, code E5 means that the shutdown is due to automatic overheating protection. Most likely there is just not enough liquid in the container. But the same error may also indicate a burnt-out temperature sensor. The presence of errors E1 and E2 indicates moisture or loose products getting inside the device or problems with the thermal relay.

Helpful operating tips and precautions

Using the delayed cooking function, you can add several ice cubes along with the food. The ice will slowly melt like in a thermos thanks to the double wall of the multicooker and the food will not have time to spoil.
If the milk porridge foams a lot and “runs away”, after adding all the ingredients, you can grease the walls with butter and place a steaming container in the bowl. At the same time, you should not use milk with a fat content exceeding 2.5%.
To ensure even cooking of foods, place those that take longer to cook—meat, root vegetables—on the bottom of the bowl, and those that require less time on top.
The heating disc and the outer surface of the bowl must always be dry.
It is recommended to fill the multicooker bowl no more than halfway, in some modes a maximum of 70%.
Do not rinse the grains in the bowl, otherwise the non-stick coating may easily be damaged.
Do not cover the multicooker lid to prevent steam from escaping.
Do not violate cooking modes. For example, you cannot cook liquids using the “baking” program.
If not provided for by the program, do not open the multicooker lid during operation so as not to disturb the mode.

Operating requirements

To protect the Redmond multicooker from breakdowns and not to think about how to fix it yourself, you must follow the requirements specified in the device instructions.

The first step is to highlight the sequence of placing food before preparing the dish. Before placing the food bowl, you must remove it from the Redmond multicooker. Otherwise:

liquids poured into the bowl may accidentally spill inside the mechanism;
forgetting that the container is on the table, you can start pouring liquid into the equipment, thereby drowning the mechanisms or covering them with bulk products.
