If there is a problem with the water heating code F19 flashes. It can be caused by low or fluctuating voltage, scale formation, burned-out heating element, temperature sensor, or board malfunction.
To eliminate it, restart the device, and normalize the voltage. If there is no change, you need to check and update the thermostat, FET, and wiring to it. In some cases, descaling the heating element may help.
Code F20 informs the user that unplanned water heating has occurred.
The error can be provoked by a program failure, a broken thermostat, or a failed heater relay (TEN). Each element must be checked and replaced, first disconnecting the device from the mains.
When the NTC sensor (thermistor) has failed, F22 lights up on the display.
There may be several reasons:
– The connection to the water supply is broken – not enough water circulates in the system, so there is no heating;
– Low or no voltage in the mains;
– failure of the controller, its wiring or electric heater;
– Wrong washing program selected incorrectly;
– Failure of level sensor or thermistor.
To fix the problem, check the fill hose and its location. Then – for the electronic board, you may need to repair or replace the element. The module wiring or electrical circuit may need repair due to burned contacts. Check the heating element and temperature sensor for proper operation, and upgrade if they are broken.
Test the water level sensor for proper operation, and if it is broken, replace it. It makes sense to connect a stabilizer, which will “save” from power surges.
Code F37 means that problems with water heating are caused by a broken NTC sensor. In this case, the sensor itself or its wiring leading to the board could be broken.
Pay attention that there are different sensors: bimetallic, gas-filled, and electronic. Each of them requires different repairs. Immediately rule out system failure and check the thermistor, wiring, and control board, then replace the necessary parts.
A short circuit of the thermistor will show up as F38 on the display. Immediately disconnect the machine from the mains. The cause of the malfunction may be a broken thermistor, voltage fluctuations, or module failure. It is necessary to inspect the NTC sensor, check the voltage, and preliminarily disconnect the washer from the mains.
Software malfunction and system protection
Code F67 indicates a breakdown or overheating of the card (controller). Immediately restart the machine. If the code appears again, there may be an error or malfunction in the coding of the card between the power and control modules.
It is necessary to call a specialist to replace it with a new working part or to reprogram the module. Repair of the card is possible if the processor is fully operational.
Code E67 is visible if the washing machine module is out of order. The error may be caused by an unstable voltage, wiring irregularities or surges in the network, breakage or burnout of key parts (capacitors, triggers, fuses), or indiscriminate pressing of the control panel buttons.
If the module has overheated, unplug the machine for 30 minutes to restart it. When the voltage stabilizes, the code should disappear. Those with technical skills will be able to repair the card themselves and replace the board, reprogram the controller, otherwise – call a specialist.
When the functional protection of the machine triggers, F63 appears on the display. The error can occur after a short circuit. The cause may be a failure of the software or a breakdown of the processor.
To fix it you need to reset the program by turning ON/OFF, then see how the module works. Code F63 is not displayed – everything is fine. Otherwise, you should call a master for a complete diagnosis and to find out the cause of the problem.
There may be several such causes. Most often, the machine can knock out the plugs or the dispenser. This is due to a breakdown of the heating element, the start button, or the motor. The primary cause of the failure of the elements lies in high humidity or oxidized contacts, and it is these that knock out the plugs or the dispenser.
If the machine does not start and F40 is displayed, it means that there has been a failure in the power supply. In simple words, the washing machine does not start.
This error can occur when:
– The voltage is below 190 watts;
– if the fuse or circuit breaker blows;
– RCDs are tripped;
– breakage of the cord, plug, socket, or noise filter has gone bad.
It may also be caused by a broken start button or circuit board.
In such cases, you should consult an electrician to fix the problem or check and replace the parts yourself.
