Dishwasher Trouble No Water entering Dishwasher

START/RESET status indicator light flashing

You have pressed the indicator light flashing START/RESET pad while the START/RESET dishwasher is running. This will cancel the cycle. The light will stop flashing after the dishwasher drains (about 90 seconds).

• Press the pad once to start the dishwasher. Press the pad a second time when the dishwasher is running only if you wish to cancel the cycle.

Power to the dishwasher was turned off while a cycle was running and power has just been restored to the dishwasher. The blinking lights indicate that the dishwasher is draining the potential water inside.

• The light will stop flashing after the dishwasher drains. A new cycle will start automatically.

Good luck

Could it be a thermostat proble?

sounds like a stuck key pad since you said the normal wash button flashed.. the other thing is try holding the door shut while you run it.. to see of it is maybe not latching properly..

Sounds like a motor problem. Behind the chopper is an access to the impeller, try turning the impeller or the chopper blade and see if the motor will rotate. If it doesn't, then something is stuck preventing the motor from running.

I asked for help when the dishwasher (GE 1991) started up and then quit. Your site was useful as we found a priority list of things to check, thus saving much time and confusion. Our problem turned out to be a disconnected ground wire.

Thanks for the help. You probably saved us a couple of hundred dollars for a repairman. We intend to replace the dishwasher next year when the kitchen is renovated so the timing was important.
