Washing machine dead or half working

A power board takes the mains supply and switches it to the motor, pump, valves and door lock as the control program asks. Because it handles the heavy current, it's the board most exposed to power surges, water leaks and worn components. A failed power board can leave the machine completely dead, or cause partial faults such as no fill, no drain, no spin or a door that stays locked. Look for burnt tracks, swollen capacitors or a scorched relay, and check for a water leak that may have caused the damage.

Swapping the power board

Disconnect the power at the wall, turn off the taps and let the machine sit for a few minutes before you open it. Photograph every connector and wire on the old board. Fit the new board in its housing, reconnect each plug firmly in its original spot, and make sure no wires sit against hot or moving parts. Fix any leak that damaged the old board before testing.

Questions about this part

Should I fix the cause before fitting a new board?

Yes. Power boards often fail because of a leak, a shorted pump or motor, or a failed valve coil. If that fault is still there, it can damage the new board straight away, so test those parts and repair any leak first.
