Brand: GE Model Number: PFW870SSV0WW Main Symptom: Power Down/Shuts off What happens & when: After you turn on the machine and press start, the machine powers down after a few seconds at about the same time a you would normally hear the pump run. How do I check the door latch and what else should I check?
Error Code (if any): 92
Parts or tests already tried: Pump ohms are at 19/20 with no obstructions. I hear an audible relay click every 40 seconds. Board appears to be clean. I hear an audible relay click every 40 seconds while powered down and plugged in. Board appears to be clean.

The door lock assembly consists of the door switch and locking mechanism. The lock mechanism functions are as follows: • To transition the lid lock solenoid, the control shall drive the lock coil for exactly 5 AC halfcycles (40 milli-seconds +/- 10 ms.). • The control shall wait 1-second before reading the lock feedback to see if the transition is successful. • The control shall wait at least 1.5-seconds between retries if a lock transition fails. • The control shall try up to three times if the lock transition fails (a minimum 1.5-seconds delay between each try is required). • If the lock is not successful after three tries, it shall provide a 30-second cool down period before trying again. • After cool down the control will try an additional four times (with delay). If the four tries are unsuccessful, a 180-second cool down will be applied and a “Critical Lid Lock Fault” will be set. Retry logic should reset on successful lock attempt or on critical lid lock fault.
To check the door switch, with the door closed, pins 1 to 2 will read open/no continuity, and pins 2 to 3 will read 120 ohms +/-8%. If no reading from pins 2 to 3, replace the door lock assembly. 2.
