GE Front-Load Washer Door Lock Error: Door Lock and Main Control Board Replaced in San Carlos

The washer in this San Carlos laundry room showed a door lock error and would not start. On GE front-load washers from the GFW650 and GFW550 families (GFW650SSN, GFW650SPN, GFW550SSN and similar versions), this error comes up quite often, and at first glance it looks like a simple door lock problem.

I replaced the door lock first. The washer still did not run, which told me the trouble went further than the lock itself.

On these washers, when the door lock burns out it can short internally. That short blows the protection for the door lock circuit on the main control board, so the board can no longer drive the lock, even with a new one installed. I replaced the main control board, and with the new lock and the new board together the washer locked the door and started normally.

The order matters here. A new control board connected to a shorted door lock can fail the same way, so the lock has to be replaced first, and only then the board. Unfortunately, that made this repair more expensive than the customer expected from a door lock error alone.

After reassembly I ran the washer through a cycle to confirm the door locked, the drum turned and the cycle advanced. The invoice total was $504 for both parts and labor, with a 6-month warranty.
