Error Code : F1 on Dexter Washer Machine
When F1 shows up, it means the door failed to close and lock or the door failed to remain locked during the cycle.

Please check VFD fault code before turning off. Check to hear if door solenoid engaged. Turn off the power to the washer. Check wire connections to door /lock switches. check wire connections from switches to controller. check P-4 wire connections at PCB controller. Adjust the door lock mechanism. (see Service Manual).
