Hoover washing machine trips electrics; motor earth fault suspected

The problem

The washing machine initially would not spin or turn. After the motor was removed and refitted, the drum turned again, but a rinse cycle then showed E03 (drain error). When set to drain, the machine tripped the electrics, and afterwards it tripped out every time it was plugged in. The owner also reported a short between live and earth at the plug when checked with a multimeter.

Likely cause

The accepted advice points to an insulation fault in the motor causing a short to earth. This is the strongest supported diagnosis from the discussion. No single control component was identified or confirmed.

What fixed it

Check the motor for continuity between each pin on the motor plug and the motor casing; there should be none. As an additional isolation check, unplug the motor and see whether the machine stops tripping. The exact repair was not confirmed in the discussion.

Checks to try

• Motor brushes inspected and reported as not worn out
• Drain checked and reported as OK
• Short between live pin and earth reportedly found at the plug with a multimeter
• Advised to test continuity between each motor plug pin and the motor casing
• Advised to unplug the motor to see if tripping stops
