What This Error Means
The F3 fault code on your Fisher & Paykel DishDrawer means: The thermistor (temperature sensor) in the wash sump has reported a reading outside the expected range. The dishwasher cannot accurately monitor water temperature.
The most common cause is: thermistor failure — resistance has drifted out of specification.
This fault is not user-fixable and requires professional service. Contact Fisher & Paykel service if F3 persists after a reset.
