Although Haier is considered a developing company, the quality of the washing machines it produces is highly rated by consumers. But malfunctions still occur in their operation, which the washing machine immediately signals with codes displayed on the panel screen. If you know the error codes of a Haier washing machine and know how to decipher alphanumeric values, then you can quickly identify and fix many breakdowns on your own.
Haier SMA Basic Error Codes
To make it easier to recognize errors that a Haier washing machine generates with codes, they are divided into certain groups.
Errors made by the user during operation
It happens that the owner of a washing machine makes mistakes - he does not add powder, overloads the drum with things, or lays them out unevenly. The machine responds to each incorrect action with a specific code:
- No solt – an error means that there is no washing powder in the tray, or the powder receiver channel is clogged. Sometimes the machine gives such a reaction to a low-quality detergent;
- UNB - using this error code, the Haier washing machine reports that an imbalance has formed in the drum;
- ERR1 – the code appears if the washing machine is unable to activate the wash cycle due to the loading hatch not being closed properly. In addition, such an error may appear if the locking device is broken.
Problems with water intake and drainage
Breakdowns of this nature are quite common and are considered the most widespread. For this reason, the Haier machine self-diagnosis system has a large number of codes for such a malfunction, which are listed below:
- ERR2 – with the help of this error code, the Haier machine reports that water is not draining according to the time set by the program. Perhaps there are blockages in the pump or drain hose, the latter could simply be twisted;
- ERR5 – means that water is not pumped into the machine’s tank. This may be due to insufficient pressure in the water supply network, a closed tap, a clogged inlet filter, a power failure in the valve responsible for the inlet, a pump or pressure switch failure; ERR8 – this code in the Haier washing machine helps to find out that more water has entered the tank. Than necessary. In most situations, this happens if the pressure switch has failed. Very rarely, such an error gives a signal that the triac on the control board that controls the sensor that monitors the liquid level is broken;
- ERR9 – this code should be deciphered like the previous one. The only difference is that it is a signal of errors that occur for other reasons – the inlet valve burns out, the triac responsible for its control fails;
- ERR10 – means a breakdown of the hydraulic system, but the inlet valve continues to function normally, and most often the pressure switch breaks down.
- Difficulties arising with water heatingERR1 - the code appears if the washing machine is unable to activate the wash due to a poorly closed loading hatch. In addition, such an error may appear if the blocking device is broken.
Problems with water intake and drainage
Failures of this nature occur quite often, and they are considered the most common. For this reason, in the self-diagnosis system of a Haier machine, a large number of codes are allocated for such a malfunction, which are listed below:
- ERR2 - with this error code, the Haier machine reports that the water is not drained according to the time specified by the program. It is possible that blockages have formed in the pump or drain hose; the latter could simply be twisted;
- ERR5 – means that water is not pumped into the machine’s tank. This may be due to insufficient pressure in the water supply network, a closed tap, a clogged inlet filter, a malfunction of the valve responsible for the inlet, a failure of the pump or pressure switch;
ERR8 - this code in a Haier washing machine helps you know that more water has entered the tank. What is necessary. In most situations, this happens if the pressure switch fails. Very rarely, such an error gives a signal that the semistor on the control board, which controls the sensor that controls the liquid level, is broken;
ERR9 - this code should be decrypted like the previous one. The only difference is that it is a signal of errors that arise for other reasons - the inlet valve burns out, the semistor responsible for its control fails;
- ERR10 - means a breakdown of the hydraulic system, but the intake valve continues to function normally, and most often the pressure switch breaks.
- Difficulties arising with water heating
- It’s time to talk about errors associated with maintaining the water temperature in a washing device from Haier. We list the error codes for these problems:
ERR3 - literally deciphered as follows: the heating element cannot heat the liquid to the temperature specified by the program. In addition, the code may indicate that the heating element has completely failed. The main causes of the problem are a power failure of the temperature sensor or its breakdown;
ERR4 - the code is deciphered in the same way as the previous one, but the cause of the breakdown is a burnt-out heating element, or a problem in the electrical wiring that powers it.
Errors meaning problems with electronics and electrical
- Haier SMA is known for the large number of wires and sensors that support the functionality of the machine. And the module is controlled by such a complex system, ensuring functionality. When something breaks, the system issues one of the warning codes:
- ERR6 – this confirms that the module board is faulty. Probably, damage has appeared on one of its tracks, or a semiconductor element has failed, or the contacts from the track to this element have been broken;
- ERR7 – this code is displayed rarely. With its help, the machine reports that several modular parts have burned out at once, and the malfunction is considered critical. Typically this occurs when there is a short circuit and the failure is considered truly serious;
- EUAR is another serious problem related to the management module. Rarely, such a code appears if a whole bundle of wiring has burned out.
If your Haier machine encounters problems with the operation of the electric motor, error code ERR 13 will appear on the screen. This means that the motor is burnt out or there is no voltage in the winding.How to fix this problem? It is necessary to check the brushes and windings and replace them if necessary.
- Test mode operation
- Sometimes the Hyer washing machine does not immediately signal a problem with the appropriate code, but the user himself understands that problems exist. In this case, you can use test mode, which is launched as follows:
- the “start delay” and “no drain” buttons are pressed simultaneously and held for some time;
- you need to make sure that the loading hatch is closed;
- the door lock is activated after ten seconds;
- testing has started.
- By the numbers that appear on the screen, you can determine which element is being tested:
77:77 – the solenoid valve is diagnosed;
