I hit the pump with a hammer and it started washing and continues to do so. Thanks

If it is the last cycle only it is not the pump. It is a wiring or timer issue. Most likely the timer.

Hello, how are you?
It sounds like you have a stuck key on the keypad, preventing you to push any other key.

I've seen this problem many times in the past 4 years.

Good luck.

The only way we have been able to fix this is to turn off the breaker to the dishwasher for 5 minutes and then turn the power back on. The dishwasher should reset.

C5 - Low Water Fill - This error usually indicates bad water inlet valve. Check for low water pressure to unit.

After leaving the dishwasher locked with the error code still showing, I returned to find that it had reset itself and run through the full cycle.
Problem solved itself.

you have set it to start after a one hour delay- just press the start delay button until it cycles through past 24h and you will get back to the immediate start mode...

The wiring diagram for GE dishwashers is usually found under the dishwasher, take the bottom panel off, then look for a envelope about 3"x5" up against the bottom side of the floor of the dishwasher, right under/behind the front edge. If its not there it makes servicing it tougher. C3 code means the drain sensor is not functioning, C7 code means the temperature sensor is not functioning.
As to the voltages used, I would only know that by looking at the wiring diagram (which I do not have).
