Washer shows E20 and will not start or stops unexpectedly

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Shorted motor, Shorted motor triac on PCB, Damaged motor harness, Overcurrent protection triggered

Safety: Unplug the washer.

Inspect motor and harness: Remove rear panel, check for burnt smell, melted insulation, or loose connectors at the motor.
Test motor windings: Measure resistance; very low resistance or visible burning indicates a shorted motor that must be replaced.
Check for drum obstruction: Ensure the drum turns freely by hand.

If the motor is sound, the PCB motor drive circuit is likely damaged and requires replacement.
