One of the most vexing problems with home appliances has to be issues with power. If your GE dishwasher works well but then stops suddenly, there are a number of possible causes. Some of these problems are serious repair issues, such as trouble with the motor, but other causes may be less serious and might even be easy to fix.
If the GE dishwasher stops working, look to see if other appliances in the home have lost power as well. If so, there may be a household-wide power failure. Wait for the power to come back on, and then select "Stop/Cancel" to clear any previous programs that remained stored in the dishwasher. Make a new cycle selection and select "Start." The power cord should also be plugged firmly into a power outlet and may have become loose if the dishwasher had power but stopped suddenly.
When other appliances in the home have power except the dishwasher, or the dishwasher shows a "PF" error code, power was interrupted to the dishwasher, causing it to stop. Select a new cycle and any other wash options, and then select "Start" to resume operation.
Circuit Breaker or Fuse
Replacing the household fuse or resetting the circuit breaker may be necessary if the dishwasher stopped due to a household-wide power outage or there was another problem with the fuse or breaker. If the dishwasher was recently installed, turn off the breaker, wait 30 seconds and then restore power to perform a reset.
Check to make sure the dishwasher door was not opened suddenly during the wash cycle and not closed completely to restart the cycle. The dishwasher will not run if the door is open, so push the door closed firmly.
Another possible reason why a GE dishwasher may stop suddenly is if the motor overheats for some reason. Keep the space in front of the dishwasher clear of objects that might block airflow and cause the unit to overheat. The dishwasher should restart automatically. If it doesn't, unplug the unit and contact GE for service.
