The sump check behind F4
Once a drain cycle finishes, the controller inspects the sump. Water still present means a faulty drain pump, and F4 (F-4) goes on the display.
Which dishwashers
Older EDW and IDW 24-inch units from the Epicure and Distinctive lines. Their service manual is where this code is documented.
Display list for this series
F-1 inlet valve
F-2 circulation pump
F-3 electrical
F-4 drain pump
Further entries continue through F-9
What to do about it
Owners get no drain procedure. First disconnect the dishwasher’s power at the breaker. A technician can then use manual test mode, where the Energy Save step starts the drain pump alone to see if it runs.

Dishwasher repair in San Francisco and Bay Area homes
Quote F4 and your model number when you call (415) 687-5926. The Dacor dishwasher repair page describes what is available around San Francisco, and it helps to mention what you tried before phoning.
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
F4 reports a drain pump fault because water is still found in the sump after the drain cycle.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
