Quick reference
Shown as
F-1 INLET VALVE, also written F1
Series
Older 24-inch Dacor EDW and IDW dishwashers (Epicure, Distinctive)
Trigger
No conductivity, meaning no water, sensed in the sump by the WPS after the fill
Why the controller raises it
When the fill ends, the WPS looks for a conductive path through the sump water. Finding none, the controller assumes the water valve or something connected to it may have failed. The service manual treats this as technician diagnosis and gives the owner no steps.
An older Dacor showing F-1 in the Bay Area can be discussed on (415) 687-5926; the Dacor dishwasher repair page outlines the work. Mention the F-1 code and the model number when you phone.
Model compatibility: Dacor reuses codes across series and model years, so F1 / F-1 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
F1 is an inlet valve fault raised when the WPS detects no water in the sump after fill.
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.
