Dishwasher - Error, Fault or Function Codes
Fault codes are programmed in many electronic dishwasher controls. These error, fault and function codes help GE service technicians quickly diagnose issues with the dishwasher. Here is a list of the various error, fault and function codes and some possible solutions for you to try. Not all codes are found on all models.

Fault code Definition Solution
C1 The pump out during drain has exceeded 2 minutes. Clean the air gap. Replace or reposition the hose. Run the disposer to clean it out. If problem persists, contact service.
C2 The total pump out cycle exceeds 7 minutes. Press RESET to stop the beep.
C3 The dishwasher will not drain Disconnect the power at the circuit breaker for about 30 seconds and then reset the dishwasher. If the problem persists, contact service.
C4 Machine filled twice after a power failure. Float switch stuck or failed. Clogged drain or sump. Touch start and then cancel/reset. Tap on the float cover to un-stick the float. This is the plastic cover that looks like an upside down cup in the front left corner of the floor of the dishwasher. Also, check the the sump area in the back bottom of the tub for debris. It looks like an upside down silverware basket and can become clogged. If the problem persists, contact service.
C5 The pump out time is too short. Make sure that the water supply is turned on. Try the same cycle again. Tap on the float cover to un-stick the float. This is the plastic cover that looks like an upside down cup in the front left corner of the floor of the dishwasher.
C6 Water temperature is too low. Water temperature coming into the dishwasher should be at least 120 degrees F. Run the faucet adjacent to the dishwasher prior to starting the dishwasher to purge any cold water from the line. Adjust the water heater temperature. Don't use the washing machine or take showers when using the dishwasher. Use options on the dishwasher to cause the machine to run longer and thus add more heat.
C7 The dishwasher's water temperature sensor circuit has become inoperative. Disconnect the power at the circuit breaker for about 30 seconds and then reset the dishwasher. If the problem persists, contact service.
C8 This display indicates that the detergent cup is blocked from opening fully. Remove obstruction (i.e. silverware, pan). Relatch door & wait 30 seconds for cup to open.
PF code Indicates that there has been a power failure to dishwasher. Simply select the desired cycle and options, press the Start pad and the dishwasher will function normally.
Cup Open The detergent cup has not been closed. It's a reminder to add detergent and latch the cup closed. When the problem occurs, the cycle will not start, but you can override by pressing the start pad again without opening the door. If this problem persists, contact service.
LEAK DETECTED Possible leak is detected. The cycle will be cancelled on models with leak detection. If LEAK DETECTED is displayed, contact service.
