Error codeF4 / F-4
ApplianceDishwasher
Quick answer
F4 (F-4) on older Dacor EDW/IDW dishwashers means water is still in the sump after draining, which is reported as a drain pump fault.
Model compatibility: Dacor reuses codes across series and model years, so F4 / F-4 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
Drain pump fault: water still detected in the sump after the drain cycle.
A Dacor EDW or IDW dishwasher from the Epicure or Distinctive range may display F4 or F-4 when the drain cycle ends and water is still sitting in the sump. The controller treats that as a faulty drain pump and shows the code.
Where F4 sits in the code list
The display list on these older models reads F-1 inlet valve, F-2 circulation pump, F-3 electrical, F-4 drain pump, and continues through F-9. F4 is the one tied to draining.
What to do
The manual gives owners no drain steps for this code. In its manual test mode a technician can start the drain pump on its own (the Energy Save step) to see whether it runs. Disconnect power at the breaker before anyone opens the base or the door panel.
Related codes
F3 is the heater side, F5 is the air flow fan label, and F2 covers the circulation pump.
