Frigidaire dishwasher codes and what to do

Frigidaire and Frigidaire Gallery/Professional dishwashers with a numeric display show codes such as i20, i40, PF and Cd. Models without a display signal problems with flashing indicator lights instead.

Codes appear in the time display; some are status messages, not faults. Frigidaire's documented reset is pressing Start/Cancel, or cutting power at the breaker (or unplugging) for a few minutes.

Safety first. Switch the appliance off at its power button and unplug it or turn off the breaker before you clean a filter or check a hose. If you smell gas, leave the home and call your gas utility from outside. If there is a burning smell, smoke, sparking or water near wiring, stop using it and keep it off until it has been checked.

When to call a technician

If a code comes back after the safe checks, or the table says it needs a technician, the fault is usually a sensor, valve, pump, motor or control board, and diagnosing it means opening the dishwasher. Our technicians repair Frigidaire appliances across Washington, DC, Northern Virginia and Maryland, seven days a week until 10 PM. Tell us the code when you book and we bring the parts that code usually points to.
