Reading the code

On display models, the code appears in the timer or cycle display; no display models may show a blinking Start light or service LED pattern. To clear a code, turn off power at the plug or breaker for 1 to 2 minutes, then restart; for 999 on GDT225, PDT145 and ZDT165 models, hold Cycle Select and Start for 5 seconds, then press any pad. Number plus H is Delay Start, PF is a power interruption, Cup Open is a detergent cup reminder, Lock Controls is control lock, and Demo Mode or Sabbath or Door Wake Up Mode are settings rather than part failures.

Have the model number ready

The company will ask for it first. It's on a sticker or metal plate, usually in one of these spots:

Open the door: on the left or right edge of the tub or door
Some models: on the top edge of the door

GE dishwasher error codes

Not all codes appear on all models; C codes are common consumer display codes, while F codes and mixed letter codes vary by model family and control generation.

47 codes

Common questions about appliance repair

Can I reset a GE dishwasher code?

Yes. Turn off power for 1 to 2 minutes, then restart the dishwasher. If the code returns, use the table and avoid repeated resets.

Why does FTD, F56 or C3 keep coming back?

Those usually point to a drain restriction, drain hose issue or drain pump problem. Check the filter, air gap, disposer connection and visible hose kink with power off, then use a technician if the drain path is clear.

Are C codes and F codes the same type of code?

No. C codes are common consumer display codes on many electronic models, while F codes often come from diagnostic modes or newer display controls and can vary by model family.

Is 1H or 2H a fault code?

No. A number plus H means Delay Start is set, so cancel the delay or wait for the countdown.
