Step 01
Signs
• Dishwasher stops mid-cycle and displays C3 error code
• Spray arms do not rotate during wash or rinse cycles
• Water fills but dishwasher will not agitate or spray
• Control panel beeps or displays error message
• Dishwasher may not start the wash cycle at all
• Motor makes no sound or unusual grinding noises when cycle begins
Step 02
Possible Causes
• Wash motor has failed or is not receiving proper 120V power supply
• Motor control board or timer has malfunctioned
• Loose or disconnected electrical connections to the motor
• Clogged or jammed spray arm preventing motor operation detection
• Faulty door latch switch causing motor circuit to disengage
• Power surge or electrical fluctuation has disrupted motor function
• Wiring harness between control board and motor is damaged
• Motor capacitor has failed (common issue in 5-10 year old units)
• Control board sensor cannot detect motor rotation
Step 03
Safety Checks You Can Do
• Check your home circuit breaker panel - ensure the breaker for your dishwasher is in the ON position; if tripped, switch OFF then back ON
• Unplug the dishwasher or turn off its dedicated circuit breaker for 60 seconds to reset the control board, then restore power and attempt a new cycle
• Open the dishwasher door and visually inspect both upper and lower spray arms for debris, mineral deposits, or food particles blocking the nozzles; rinse clean with water
• Verify the door closes completely and latches securely - listen for the latch clicking into place
• Ensure the spray arms spin freely by manually rotating them by hand when dishwasher is empty and unpowered
• Check that no dishes or utensils are blocking spray arm rotation paths
• Review your dishwasher's cycle selection on the control panel - ensure you selected a standard wash cycle (not a specialty cycle that may have limited motor usage)
• Allow 5-10 minutes after a power outage or reset before running a new cycle, as the control board may need time to reinitialize
• Verify the outlet the dishwasher plugs into (if portable model) is functioning by plugging in another appliance
• If error code persists after these checks, contact a GE authorized service technician in your area as motor replacement or control board repair will likely be needed
