Difficulty

Start with the safe checks below; a worn part may need replacing.

Safety first: unplug the dishwasher (or switch off its breaker) before touching filters, hoses or panels. If you smell burning or gas, or see water near the outlet, stop and call a professional.

How to fix GE C3 / FTD / F56

  1. Clean the filters and sump

    Unplug the dishwasher or switch off its breaker. Remove the lower rack, take out the fine filters if your model has them, and rinse them. Clear paper, labels or food from the sump at the back of the tub floor. A cup or two of clean water left in the bottom is normal on many models.

  2. Check the drain hose and sink drain

    Under the sink, look for kinks or clogs in the drain hose. Run the garbage disposer before starting the dishwasher (never reach into the disposer), and if the disposer is new, make sure its knockout plug was removed. Do not pour chemical drain cleaner into the dishwasher.

  3. Clean the air gap

    If your sink has an air gap (a small cap near the faucet), pull off the cover and clear out food or debris. If there is no air gap, the drain hose needs a high loop under the counter as shown in your installation instructions.

  4. Reset the power

    Switch off the dishwasher's circuit breaker (or unplug it) for about 30 seconds, then restore power and start a new cycle.

When to call a technician

If the drain path is clear, the right detergent is in use and the code returns after a reset, schedule service for the drain pump.
