GE Electronic Dishwasher Code C3: Tub Will Not Drain at All

Medium · inspection needed

Code: C3
Appliance: Dishwasher
Brand: GE
Warranty: 30-day workmanship

What C3 means

On GE electronic-control dishwashers with C-codes, such as the PDT855SSJSS, C3 tells you the dishwasher will not drain. The control tried to empty the tub and the water stayed. You will find water standing in the bottom, a cycle that stopped, and a code on the display. A blocked path or a pump that is not moving water can both look like this. The code reports the result, not the reason, so the cause has to be found by working along the drain path.

Common causes of C3

Drain hose or air gap blocked
Disposer inlet still plugged
Filter and sump packed with debris
Drain pump or its control not running
Check valve or hose restriction

✓ One safe check you can try

1. Switch the breaker to the dishwasher off for about 30 seconds, then switch it back on. 2. Clear the filter and look for debris in the tub. 3. Clean the air gap and straighten the drain hose. 4. Run the disposer. 5. Start a cycle again. If C3 stays, leave the water in and book a visit.

! Why to stop there

A breaker reset does not remove a blockage, and it cannot revive a pump that has stopped.
We test the drain path first and the pump next, so you pay only for what is needed.
The price is in writing before any repair.

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

C3C3 questions

Why does my GE dishwasher show C3?

It reports that the dishwasher will not drain. Water stays in the tub because of a blockage or because the pump is not moving it.

Should I bail out the water?

You can scoop standing water out with a cup or towel to reach the filter. Keep the dishwasher off until the cause is found, so it does not try to run again.

Can a breaker reset clear C3?

A reset can clear a stuck control after a power event. If water is still sitting in the tub, the drain path or pump still needs attention.
