Fisher & Paykel Dishwasher Error Code F9
Overflow detected in the drawer
Common Causes
- 1Inlet valve stuck open and unable to shut off
- 2Failed water-level or pressure sensor
- 3Control module misreading the water level
- 4Debris holding the inlet valve open
Step-by-Step Troubleshooting
- 1
Note that on F9 the drain pump activates and the cycle aborts to protect against overfill
- 2
Check whether the inlet valve is stuck open — water entering while the drawer is powered off confirms it
- 3
Inspect the valve seat for debris preventing a full close
- 4
Test the water-level or pressure sensor for a plausible reading against the drawer state
- 5
If the valve seals correctly, suspect the level sensor or the control module misreading level
Pro Diagnostic Tip
F9 is too MUCH water inside the drawer — an overfill from a stuck inlet valve or a bad level sensor — not water in the base pan. A valve that keeps filling when the drawer is switched off is the clearest confirmation of a stuck inlet valve.
