GE Dishwasher Control Error

My GE Nautilus GSD4800 is indicating a control error by flashing the ‘NORMAL’ button. I ran a wash last night and found it blinking and beeping. Opened it up and found water in basin. Tried to press reset button…no joy. Drained water from basin and tried to reset again, same blinking ‘NORMAL’ light and it was filling up again. Tried cutting power from breaker on/off and hasn’t helped. What is my next step? Thanks!

I’ve done some more troubleshooting. The tub fills and float trips the water solenoid valve to close…stopping flow of water into tub. So it’s not the float. I was able to suck water from the drain tube, so it appears to be no obstruction in drain. However, once the tub fills the unit is stuck in the wash cycle. ‘NORMAL’ button light is blinking/beeping. I can hit ‘RESET’ button, but it blinks and then eventually ‘NORMAL’ button/light blinks and beeps. I’ve also shut off power to the washer several times. No help there. Any suggestions? Thanks!

I am not sure about floats, and the reason lights are blinking, but when my dishwasher is not draining it has always been the clogging of the air vent. Mine is located on top of the sink and is covered with a chrome cap.

Remove the cap and unscrew the base nut, (careful not to allow nipple to fall through the hole). You should be able to pull the tube out a bit and enter the air chamber to clean out foodstuffs that clog the air vent, thus not allowing the tub to drain. Hope this works!

I can trigger my dishwasher to drain by pulling on the solenoid under the tub that controls wash and drain cycles. I checked for continuity on the heating element and it seems to check out. The GE Nautilus does not seem to have a thermostat that triggers timing for wash cycle. Still is stuck in wash cycle with ‘Normal’ light blinking/beeping. I am more convinced that it is the timer unit or the circuit board. Anyway to troubleshoot these? Anyone have a repair manual?

I’ve pulled the cycle sequence switch and opened it up. Looks fine and confirmed that the small DC motor run inside by hooking it up to 6V battery. I think that my problem is the timer control assembly (Part #905 on schematic).
