Error codeF8 / F-8

Quick answer
F8 (F-8) on older Dacor EDW/IDW dishwashers is a data error between the control board and the power board.
Model compatibility: Dacor reuses codes across series and model years, so F8 / F-8 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
Communication failure: data error between control board and power board (wet low-voltage connector is the most common cause).
F8, also shown as F-8, is a communication failure on Dacor EDW and IDW dishwashers (24-inch Epicure and Distinctive, an older series). The control board in the door and the power board in the base are no longer exchanging data cleanly.
What the manual says about the cause
The control board is the master micro and the power board is the slave. The error can occur in a few ways, and the wet connector is the most common one. That low-voltage connector runs from the door to the base with four wires: ground, 5 VDC power, data and neutral.
What to do
The wiring sits in the door and base, which is technician territory. Disconnect power at the breaker and describe the symptom when you book a visit.
