Dishwasher - Error, Fault or Function Codes

Fault codes are programmed into dishwashers that have electronic controls. These fault codes, also called error or function codes, help GE Appliances repair technicians quickly diagnose issues with the dishwasher. Some codes provide guidance for issues you can potentially correct yourself. However, most fault codes indicate issues that will require a repair technician to resolve the concern.
 
Here is a list of the more common fault, error, or function codes and some possible solutions for you to try. Not all codes are found on all models.

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 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.
C5The 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.
C6Water temperature is too low.The 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.

If H2O appears during other wash cycles (AutoSense, Heavy, Normal or Light), then double-check that the inlet water hose is not kinked. If neither of the above apply, call for service.

Service and Support

Sometimes disconnecting power to the dishwasher for a minute or two will clear the fault, error or function code. If this simple reset of the appliance does not clear the code, service may be required. For service, please schedule a repair appointment with GE Appliances Factory Service.
