Error codeF9 / F-9
ApplianceDishwasher
Quick answer
F9 (F-9) on older Dacor EDW/IDW dishwashers is labelled WPS SENSOR on the display list.
Model compatibility: Dacor reuses codes across series and model years, so F9 / F-9 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
WPS sensor, as labelled on the display list.
F9, or F-9, is the last code in the display list for Dacor EDW and IDW dishwashers, and it is labelled WPS SENSOR. These are the 24-inch Epicure and Distinctive models, an older series.
What the label points to
The label names the WPS sensor and nothing more, so the display list is all an owner has to go on.
Owner steps
None are printed for F9. Switch the dishwasher off at the breaker and ask a technician to check it.
Related codes
F1 is the inlet valve code, where no water is detected in the sump after fill. F8 is a board communication failure, and F7 is the EEPROM failure.
