Frigidaire / Electrolux: diagnostic mode, last-fault recall and relay-test codes that are not faults
Newer Frigidaire/Electrolux dishwashers show i-codes (i10, i20, i50 and similar) and two-letter codes; during the relay test inside diagnostic mode they also show short codes that only confirm the test is running and are not faults. Front-load washers keep a last-code readout you reach with a button pair or knob position. Refrigerators lose the fault code when the plug is pulled. Entry sequences differ by model and the sources conflict, so get them from the service data sheet on the unit.
Before you start
- Turn off the breaker before removing the dishwasher kickplate or panels
- Relay tests energize pumps, heater and valves; keep the door closed
