GE dishwashers Error Codes and Troubleshooting

General Electric Dishwashers are, generally, designed to be easily accessible and offer maximum features and still qualify for Energy Star ratings. Even if you have older units at home, they probably had a good run already. But every now and then appliances break and we are so dependant on them for reliable service.

Is your GE dishwasher broken?

While some units seem to work smoothly and then suddenly stop dead, others show the signs of problems before. Unusual sounds, signals flashing, cycles not complete, water not draining properly, and throwing error codes at you… Sometimes only later you understand that it was not a temporary glitch, but a signal of serious malfunction.

The truth is, we are running such a busy schedule at work, home and with kids, and do not have enough time and patience. We force the buttons, reset, slam the doors in an effort to make the dishwasher work, avoiding making the service call at all costs. Unfortunately, mechanical and electrical problems do not resolve themselves. If anything, they tend to become more serious and costly if ignored.

Yes, you might come up with a temporary hack to fool the system, but in the long run, you might end up paying more.

GE Dishwasher: Blinking lights and beeping sounds.

Although you might not have the most recent model of GE dishwasher, that already can do more advanced self-diagnostics, blinking lights and beeping sounds are designed to draw your attention. Familiarizing yourself with the owner’s manual will give you easy explanations about your specific model since dishwasher beep codes may mean different problems.

Beeping sound with 30-second interval: The door did not latch during the cycle. Check if anything obstructs the door. Resume cycle.

Blinking and beeping might also be caused by power surges (or interruption) or to the fact that the dishwasher was reset. During this time for safety for 70-90 seconds, the water will be pumping out the water. Wait while the dishwasher is draining water to start a new cycle.

Some of GE models (starting with GDF/GDT/PDT/CDT/DDT/ADT/ZDT) come with beeping sounds on key functions as factory default settings. To turn off all sounds press the HEATED DRY BUTTON or the POWER DRY BUTTON 5 times in quick succession. For models that have an LCD display ( GE Models GDT580, CDT725SSF, GDT720SSF) press the HEATED DRY BUTTON or the POWER DRY BUTTON 7 times within 5 seconds

To reset the unit completely to clear some codes, or if the unit’s lights keep blinking after the power surge – turn off the circuit breaker (or unplug the unit), wait for approximately 2 minutes, turn on the circuit breaker, or plug the unit back.

Most Common GE Dishwasher Error Codes

User manual for your model will contain the information on your GE dishwasher model, here are some of the most common error codes:

  • GE dishwasher code 2h, 5h, 9h. Points to the delayed wash start mode. The feature is very useful when you want to take advantage of off-peak hydro rates, schedule the dishwashing to work when nobody in the house is using the shower, or simply want to have your dishes done by a certain time. You have to keep in mind that unlatching the door does not cancel the delayed start mode. GE Dishwasher Code C1 – The machine exceeds the pumping time (2 min) – Check the hose.
  • GE Dishwasher Code C3 – The dishwasher does not drain – Disconnect power, reset the dishwasher.
  • GE Dishwasher Code C4 – Machine filled two times either after a power failure or due to the problem with float switch. Also possible clogged drain. – Check the float, if it is stuck and the drain. Check the sump for debris.
  • GE Dishwasher Code C5 – Pump out time is not long enough to pump out the water. – Check the water supply and the float.
  • GE Dishwasher Code C6 – Water temperature is too low (the water temperature should be at least 48 degrees). – Make sure your water heater tank is set to the higher temperature, also someone using hot water might affect the process.
  • GE Dishwasher Code C7 – Water temperature sensor fails
  • GE Dishwasher Code C8 – The detergent dispenser is blocked

LEAK DETECTED – leaks are of special concern in dishwashers for 2 reasons, – they might damage the floor, or pose a risk of short circuit. That is why, when there is a leak detected, it is indicated by the words, not a code, not to confuse with any other problem. In models “floor protect with alert” fault code 999 may stand for the same problem. In older models, you will find that F34 code stands for the same problem.

When researching the information on the error codes it is important that you refer to the correct GE model.

In general, error, or fault codes are developed to help service technicians to diagnose the problem. It is important to understand that it sometimes does not reflect the problem, but the fact that the machine “thinks” what the problem is. It might misinterpret the signals.
