Washer shows a code, stays locked or won't start after a power outage

Outages and surges can leave the control in a confused state mid-cycle. A full power reset clears most cases. If the code returns, read it and diagnose the part it names (lock, pump, valve); if the control is dead or erratic after a surge, the main control may be damaged.

Washer won't start

Check power, control lock, door/lid, and any install-check requirement before suspecting boards. Many 'won't start' calls are lock modes or lid/door issues.

Hall sensor and tach generator (motor speed feedback)

Hall sensors are 3-wire devices (supply, ground, signal) that switch as magnets pass; tach generators are 2-wire coils that make a small AC voltage as the motor turns. Test the right way for the type.
