Repair of Zanussi washing machines: analysis of the most common breakdowns

Zanussi washing machines are widespread in apartments and houses. They are advertised and promoted as being from a trusted European brand. However, in practice, all products from this manufacturer, without exception, have weak points. Therefore, you need to know how to repair Zanussi washing machines when frequent breakdowns occur - this will help save time and money on calling a qualified specialist from the service center.

Features of the Zanussi washing machine

Without exception, all Zanussi machines, whether vertical or horizontal loading, are carefully designed engineering solutions. The manufacturer, on the way to conquering the market with reduced cost of products, got rid of most of the technological stocks. As a result of the machine:

• sensitive to the quality of tap water;
• have a drum block bearing that is quite sensitive to overloads and quickly fails when overloaded or unbalanced;
• require correct installation, including drain hose placement.

Also, due to power outages or voltage surges in the network, the electronic control board may fail. But in general, repairing a Zanussi machine when non-critical problems arise is not difficult. There are simple solutions for most problems. For example, the Zanussi machine circuit includes special means that allow you to manually unlock the door lock for storing laundry.

Typical breakdowns

Having studied statistical data from service centers that repair Zanussi washing machines, we can identify several typical problems for this brand:

1. Related to water quality. Tap water in Russia is characterized by increased hardness. And there are problems with cleanliness - because of old pipes. As the water is heated to 90–95 degrees, a sediment forms—scale. Due to the sediment, the tubular electric heater (TEH) does not transfer heat well and overheats. Dirt and rust particles contained in the water clog the filters - the water intake and drainage system suffers.
2. UBL (hatch blocking device). This unit breaks more often due to the fault of the manufacturer. There are obvious shortcomings here - the UBL and the sensor in the Zanussi SM fail more often than in devices of competing brands.
3. heating element. Burns out due to scale buildup. In addition, it has a limited service life and may burn out after 3-5 years of intense use. But experts also assure that the heating elements of this brand have poorly selected components from which the tubular part is made.
4. Drive belt. This element cannot boast of reliability. It is recommended to check the belt for integrity and tension once every three months. If there are stretch marks (damage), it will have to be tightened or replaced.

Common problems

One thing is certain: all problems in the operation of the machine are most often associated with the negligence of the owner. This may be an ignored instruction or incorrect installation. Housewives often overload or underload the drum, creating imbalances.

Even more cases of breakdowns are associated with improper operation and foreign objects entering the working paths of the device. There are also options when repairs are made due to wear and tear of system components.

Blockage

Clogging is a problem for all Zanussi cars without exception. This can be either a simple model or a fairly advanced device, for example, Aquacycle 800 or 900. All brand machines are very sensitive to the quality of tap water.

When installing the machine, it is recommended to install a separate fine filter at the inlet. It’s inexpensive and you won’t have to frequently remove the consequences of blockages.

If the machine is connected directly to the water supply, you need to clean the inlet filter mesh. Removing the blockage looks like this:

• the supply hose is unscrewed;
• unscrew the input filter from the machine body;
• the mesh is removed;
• cleaned and, if necessary, soaked in vinegar or a mild descaling agent;
• the filter is assembled, screwed into the housing, and a supply hose is connected to it.

You can often repair a machine with your own hands in this way. The filter device includes a procedure for removing and cleaning the mesh.

Extraneous noise during operation

Extraneous noise is the most common problem. This phenomenon may be caused by the following reasons:

• drum imbalance due to underloaded or overweight laundry;
• damage to the bearing block.

It is worth noting that malfunctions of a Zanussi horizontal-loading machine in the form of extraneous noise in any operating mode will most likely require the intervention of a qualified specialist. The cause is parts of mechanical components. This could also be a fairly harmless case when the shock absorber of the engine block is weakened or unbalanced. But the reason may lie in damaged bearings. In this case, the entire unit must be replaced.

Top-loading machines use a different type of drum mounting. In devices of this type, the unevenness of the load in the area of ​​the bearing block is small, so extraneous noise, if it does not arise from loading laundry, but is present in all operating modes, necessarily indicates the complexity of the problem. Specialist intervention is required.

Bad spin

Poor spinning of laundry is always associated with the inability to achieve the required drum speed. The reasons for this phenomenon may be:

• insufficient supply voltage. Checked with a meter;
• poor belt tension causing slippage. The damage can be eliminated either by tightening or replacing.

But most often the machine begins to spin poorly when the laundry is loaded incorrectly. It may be overweight or underweight. In all cases, imbalance occurs and electronic control does not allow the engine to develop the required speed.

The problem can be solved either by dividing the laundry into two portions for separate washes, or by adding a clean towel and other things to the tank to gain sufficient weight.

Malfunctions related to water supply, heating, drainage

Partially the case when water is not supplied to the machine is described above. The problem can be resolved by cleaning the device's inlet filter. But the machine may not take in water due to a broken pressure switch. This happens rarely, but it does happen.

Zanussi devices have a rather complex unit of this class (in most models it is electronic), so you should contact a specialist to check and replace it. Water may not be drawn due to insufficient pressure. In this case, the pressure switch simply does not detect its presence at the input. Solving this problem also requires the intervention of a specialist.

Lack of heating may be due to a broken heating element. Most Zanussi car models have a display or display system. If the heating element breaks down, an error appears on the warning device.

This may be a character-numeric code or a combination of diodes. Based on the display readings, you should find the “faults and troubleshooting” section in the instructions for the Zanussi washing machine and determine the cause of the breakdown.

To repair the heating element, you will need skills in using measuring instruments and a soldering iron. An electrical tester will be required. By measuring the resistance of the heating element, its serviceability or winding breakage is determined. In the latter case, the wire leads to the heater contacts are unsoldered, the element is unscrewed from its socket and replaced with a new one.

The most unpleasant situation is when water is thrown out of the machine during washing. There are cases when water flows in and at the same time it is discharged into the sewer. Such problems are associated with incorrect installation of the device. The upper level of the drainage path must be raised no lower than the level specified in the instructions for the model.

Typically, Zanussi devices require the hose to be positioned at a height of at least 60-80 cm from the point of entry into the sewer. There is a special clip on the body of the machine for attaching it. Therefore, if the machine begins to drain water at the same time as filling or throws it away during washing, you should check the location of the outlet hose.

Hatch lock

Zanussi cars are equipped with a rather fragile blocker. Its locking system (locking teeth) is made of plastic. In addition, electrical control elements are located inside the unit. If the blocker refuses to lock the lock, you should:

• open the door;
• in the area of ​​its handle, find on the body a block with two screws securing the safety plate with a square hole;
• carefully bend the rubber cuff in this area, after first removing the thin wire clamp that holds it in place;
• find the blocker with your hand and fix it;
• unscrew the screws;
• remove the cover and pull out the blocker;
• disconnect the terminal with wires.

The blocker needs to be changed in any case. The device may show obvious mechanical damage in the form of broken plastic teeth. The unit may not turn on due to a breakdown of internal electronic components, so the only solution is to purchase a new blocker model.

If the unit breaks down during washing and you cannot open the door, you should remove the lower decorative panel of the washing machine; a special cable is hidden behind it. To open the door, just pull it. Then you should follow the above scheme to remove the blocker. The new node is installed in the reverse order of steps.

Drum jammed

For users, the concept of “jammed” is quite broad. In the form of a list of options and methods for troubleshooting, it looks like this:

• entry of a foreign object. The drum refuses to spin or stops unexpectedly during the washing process. On top-loading machines, blocking may occur due to the loading doors not being closed. The problem is eliminated by removing the interference that has fallen between the parts of the structure;
• initial startup failure accompanied by a humming noise. This is a clear indication of problems with the bearing block. It is recommended to call a specialist;
• no rotation with the sound of the engine running. The problem may be either a break in the drive belt or it flying off the pulleys. If it is possible to disassemble the case and check the condition of the element and correct it, this must be done.

The most difficult locking problem is a broken bearing or drum spider. In these cases, expensive repairs will be required. It is also unpleasant for foreign objects to get into the machine. When the drum jams, the structure of the apparatus is inevitably damaged.

Drum doesn't move

If you can clearly hear that the engine is running, then the problem is most likely in the drive belt. To inspect it, you need to remove the back panel of the machine body by unscrewing the screws that secure it.

Next we act on the situation:

1. If the belt has come off one of the pulleys, it needs to be put back in place.
2. If the belt breaks, you need to purchase and install a new one.
3. If the belt is intact and in its place, but does not transmit rotation due to slipping, it means that it has exhausted its service life and must also be replaced.

If, during inspection, you find that the electric motor pulley does not rotate, it means that there is a more serious breakdown and you need to contact a service center.

DIY machine repair tips

The rules for repairing Zanussi cars with your own hands are quite simple. It is necessary to correctly identify the problem. Error codes, frequently occurring malfunctions and methods for eliminating them are necessarily given in the instructions for a particular model.

The second correct tactic is to completely disconnect the device from all sources. This applies to both electricity and water. Only after this can you begin to check the cleanliness of the filters, the position of individual components and other work. In addition, you need to use working tools with insulated handles and carefully clean up water if it is spilled on the floor.

It is worth remembering: with proper installation, ensuring high-quality power supply and clean water, Zanussi washing machines operate without failures. In order not to struggle with problems, it is enough to properly operate your automated home assistant.

Error codes

The modern Zanussi automatic washing machine is equipped with a self-diagnosis function. Fault codes indicate a breakdown, but do not always allow you to understand its cause - you need to figure it out. The display shows error codes that you need to decipher and then decide what to do next. In difficult situations, contact the service. Below are some commonly encountered codes.

Table 1

In the instructions you can find a complete table of decoding codes - there are dozens of them, we have given only a few to clearly explain how the self-diagnosis system works.

Control board

The user sets the desired washing parameters by pressing keys on the control panel. You can select the desired mode by rotating the selector knob, activate additional functions, adjust the temperature and the number of revolutions. The “tidy” is connected to the main electronic module.

Zanussi's main control board consists of semiconductor elements: microcontroller, triacs, capacitors, triggers, thyristors, resistors. Communication with the main parts and components of the machine is carried out via electrically conductive paths.

It is the control board that ensures the sequential execution of cleaning programs. All available washing algorithms and parameters are pre-recorded in the electronic module circuit. This gives the user the opportunity to launch the required mode without errors using the dashboard.

Some washing programs are carried out strictly according to the algorithm recorded in the “intelligence”. Individual modes can be adjusted - changing the water heating temperature and spin speed.

Leakage

Malfunctions associated with water leakage cause great trouble, but are quite easy to fix. Usually this phenomenon provokes a weakening of the seals. A simple replacement of the gaskets at the hose connections will be enough to restore the machine’s functionality. It is somewhat more difficult to eliminate a hatch seal leak. You have to first remove the seal retaining clamp. This operation is easy if you carefully pry it off with a screwdriver. Replacing and installing a new seal usually does not cause any difficulties.

In order to repair a Zanussi washing machine at home, you need to understand electrical engineering and plumbing, have special tools and simple measuring instruments. In this case, success will be guaranteed.

Heater circuit

The tubular electric heater is considered the most vulnerable part on a washing machine of all brands, and especially on Zanussi. Here, the coating used on heating elements is far from ideal, which often leads to rapid scale accumulation with subsequent problems. The washing machine, in this case, displays the fault code “E05” on the screen, indicating that it is impossible to heat the water.

To check and repair the heating element you must:

• turn the washer “backward” forward;
• remove the back panel by unscrewing the corresponding bolts;
• find the “trick” of the heating element - located under the tank with two contacts and wiring;
• touch the probes and measure the resistance.

A working heater should show 20-40 Ohms. Numbers closer to “0” will indicate that a breakdown has occurred. The heating element cannot be repaired; it must be replaced.

To remove the heating element, you need:

• unscrew the central nut;
• press the pin inward;
• release the connected wiring;
• remove the heating element.

It is recommended to use only branded spare parts for replacement. Third-party heating elements will not last long or will cause damage to the control board.

Most common faults

If you follow all the points in the operating instructions, the washing machine will serve you for a long time. And if you carry out timely and high-quality service, then it will work uninterruptedly. Unfortunately, such an attitude towards technology is not always observed. Ruthless use without proper care leads to breakdowns. Sometimes quite serious. Only a service center technician can deal with them.

However, simpler breakdowns often occur that allow you to repair the machine yourself. The most common ones include:

• the drum does not spin;
• the hatch does not open after washing;
• water is drained simultaneously with its collection;
• water does not enter the machine;
• water heating does not work;
• leakage.

To eliminate such malfunctions with your own hands, you need tools and experience in performing plumbing and mechanical work.

Hatch lock

Let's consider two situations:

The washing is completed, but the hatch still cannot be opened

If the lock is jammed, the hatch can be opened using the emergency cable by pulling it towards you. You can find it behind the bottom panel (you need to unscrew it), on the right, near the filter. The cause of the malfunction lies in the electronics, so you will have to contact a workshop.

The hatch won't close

The latches that hold the hatch in the closed position are made of fragile plastic, so they often break.

To make sure that this is the case, you need to disassemble the lock:

• Having opened the hatch, unscrew the two screws that secure the lock to the body;
• remove the hatch seal (cuff), having first removed the clamp holding it (you need to pry it off with a screwdriver);
• After removing the cuff, the lock can be pulled out.

If the plastic parts of the mechanism are really broken, you need to purchase a new lock and install it in place.

To make the lock last longer, close the hatch as gently as possible.

Rumble during spin cycle

Loud noise when the drum rotates at high speeds may be due to the following reasons:

1. The position of the machine is not strictly horizontal.
2. The drum is underloaded, as a result of which the center of gravity of the laundry has deviated from the center of rotation (strong vibrations will occur at high speeds).
3. One of the bearings is broken.

Bearings in Zanussi cars can be replaced independently. This is done like this:

1. Having completely disassembled the machine, you need to remove the tank with the drum.
2. After removing the drum pulley and unscrewing several bolts around the perimeter of the tank, the latter needs to be disassembled into two parts.
3. Using careful blows of a hammer through a wooden lining, you need to knock out the drum axle shaft from the bearing assembly in the rear half of the tank.
4. Next, using a puller, remove the bearing itself along with the seal.
5. The drum axle shaft and bearing seat must be thoroughly cleaned.
6. A new one is installed in place of the old bearing, and its seal is filled with special lubricant.

Having lubricated the axle shaft and the inner ring of the bearing, the drum and the rear part of the tank are again assembled into a single unit, after which both halves of the tank are fastened together, coating the joint with sealant.

Self-draining device

The situation when, simultaneously with the collection of water, it is discharged through the drain hose (before the drum begins to rotate), may be due to the low location of this hose. Its free end should be raised by 50 - 70 cm.

Self-draining will also occur if the drain pipe is damaged, only in this case the water will not flow out of the hose, but from under the machine.

More serious causes are failures in the control module or level sensor, which mistakenly turn on the drain pump.
