Behind the code F21 there is a breakdown of the motor because the rotation of the drum depends on it. When you see this code, you must immediately interrupt the washing, unplug the device, drain the water, remove the laundry, wipe the inside of the drum, and call the master.
The culprits for this error may be:
– too large a load of laundry;
– a stretched or damaged drive belt;
– Control board malfunction;
– TACHO sensor breakage, worn out motor brushes;
– motor failure;
– Object stuck in the tank blocking rotation;
– Worn or leaking bearings.
To fix, check the drive belt for tears – it may need to be repaired or renewed.
Inspect the wiring and control box, wires, and contacts – sometimes a module may need to be replaced. If the machine runs on a commutator rather than a direct drive motor, an important part of the motor may have been damaged – the carbon brushes. These are not repairable and must be replaced.
Next, test the motor, if necessary, repair or replace it with a new one, disassemble the body of the washing machine and remove the foreign object, renew the bearings.
If there are problems with the operation of the motor, a critical error E02 occurs. Turn off the machine right away, or there is a risk of burning the wiring or motor, and call Chula Vista Appliance Repair Company. He will check if: motor graphite brushes, motor, motor resistance, connecting contacts, key modules, as well as motor modules, and TAHO sensor are in order.
Software malfunction and system protection
Code F67 signals 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. The card can be repaired if the processor is fully functional.
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, it is necessary to call a master for full diagnostics 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, consult an electrician to correct the problem or check and replace the parts yourself.
