DIY Haier washing machine repair

Haier washing machine repair Modern models of automatic washing machines facilitate not only the washing process, but also the ongoing maintenance of the unit itself. For these purposes, an encrypted message is provided on the electronic display - the code of the error that occurred. Knowing its meaning, repairing a washing machine can be easier and faster, because it is not difficult to guess which element is faulty and from which “side” to approach the equipment. What signals does the Haier system give and how to correct the situation on your own - read the article.

Self-diagnostic system database

There are more than ten error codes in the database of the self-diagnosis system of the Hyer machine. These range from minor problems with an unlocked hatch door to dangerous warnings with a risk of fire. A list of standard combinations will help to assess the scale of the situation:

ERR Indicates that the machine is unable to start the cycle. The door may not be closed tightly or there are problems with the locking mechanism or hatch locking device.
ERR Detects the absence of a complete drain for 4 minutes. Such consequences result from a faulty pump, blockage or squeezing of hoses and pipes.
ERR Error with water heating. It is caused by a loss of communication with the temperature sensor due to a defect in the thermostat itself or the wiring connected to it.
ERR Another error when heating water. Here, the “culprit” is a failed heating element or damaged wiring between the heating element and the control module.
ERR The tank has not been filled with water within the specified 8 minutes and the wash cannot start.There are several reasons: no water supply, low pressure in the water supply, blockage in the inlet hose, breakdown of the inlet valve, pressure switch or pump.
ERR The main control module has become unusable. More precisely, the wiring of the control board or module elements is faulty.
ERR Extremely dangerous! Possible fire! The culprit was a short circuit or other current leakage problems.
ERR Water transfusion has been diagnosed. The pressure switch or the module triac responsible for receiving signals from the sensor has broken down.
ERR The permissible volume of water in the tank has been exceeded. There is a problem with the intake valve or control element.
UNB. Imbalance. The laundry is unevenly distributed along the walls of the drum and does not allow the machine to continue washing.
EUAR. Indicates faulty electronics or damage to the wiring harness of the electrical unit.
NO SALT. A problem has arisen with the cleaning agent: there has been a reaction to the composition of the powder, its absence has been detected in the tray, or the dispenser has become clogged.

Once the general location of the breakdown has been determined, you can begin specific diagnostics and direct repair of the leaky part. We look for the appropriate instructions below and begin to correct the situation.

The hatch stopped locking

hatch won't lock If an ERR1 error occurs, repairing a Haier machine with your own hands is not difficult. It is enough to repeat closing the door or press it more tightly to the body until a characteristic click is heard. It would be a good idea to check if there is any underwear stuck in the cuff.

If the signal combination does not disappear, check the lock:

open the door;
inspect the latch tongue;
when it is displaced, we return it to the correct location;
feel the hinges; if they are loose, tighten the fastenings.

The electronic lock may not work. The UBL is checked with a multimeter.If there is no proper resistance, the locking mechanism will have to be replaced.

Water drainage is difficult or not possible

It is not difficult to solve the drainage problem yourself. It is enough to check all existing hoses and pipes for blockages, inspect the pump impeller and clean the debris filter. This is done through the drain hatch located on the front panel in the lower right corner. Open the rectangular door by prying it with a screwdriver, drain the water into the prepared container, unscrew the filter and remove the accumulated dirt. At the same time, we check the integrity of the tubes and the free rotation of the impeller.

The water stopped heating

the water does not heat up due to the heating element For errors ERR3 and ERR4, the system has detected a malfunction with the heating element. Harbingers of a deteriorating heating element will be poorly washed dirt and a musty smell from the laundry. Confirming the failure of the heating element is simple: place your palm on the door 20 minutes after starting the cycle. A cold surface will prove that the water is not heating.

The final test is carried out with a multimeter. We disconnect the machine from the network, unscrew the back cover and find the heating element under the tank. Disconnect the wires, loosen the middle nut and take out the element. All that remains is to connect the meter probes and evaluate the results on the display.

Water does not fill into the tank

Often an error indicates the machine’s inability to fill the tank with water to start the cycle. The cause is failure of the dial valve, pressure switch, control unit or clogged filter mesh. To solve the problem, you need to more accurately determine the source of the malfunction; you need to take a number of simple steps.

If the powder in the dispenser is not washed out, then the supply valve is at fault. The situation will be corrected by closing the network by supplying 220 V to the device, after which water will flow into the tank. If there is no response to the current, unscrew and replace the element.
When the machine hums and takes a long time to fill, clean the mesh.
The pressure switch is checked by blowing through the fitting with a tube of suitable diameter.

electronic module If unsuccessful, we stop self-diagnosis. Most likely, the corresponding resistors on the module have burned out and need to be replaced. Only a professional master can handle this.

Electronic module failure

For errors ERR6, ERR7 and EUAR, self-repair of the washing machine is prohibited. The maximum that an amateur is allowed to do is turn off the power and start the machine after 20 minutes. If the code does not disappear from the display, you will have to call the service. The technician will arrive, remove the control module from your machine and take it to the workshop for diagnostics and repair. Handicraft repair of a module is fraught with problems and an increase in the cost of repairing the breakdown.
