Fisher & Paykel DishDrawer Error Code F9 — Electronic Control Board Failure
What this means
Error code F9 on Fisher & Paykel DishDrawer dishwashers indicates the main PCB (printed circuit board) has experienced a serious internal fault. This is a catch-all code for control board issues that do not fall into other specific fault categories. It may appear after a power surge, due to component failure on the board (blown capacitor, failed relay, or microprocessor error), or from moisture damage to the electronics. The DishDrawer will typically be non-functional when this code is displayed.
Alternate codes: Fault 9, Error F9
Step-by-step fix
4 stepsPerform a hard reset
Disconnect the DishDrawer from power at the circuit breaker. Wait 10 full minutes — this extended reset allows all capacitors on the control board to fully discharge. Restore power and check if the F9 code clears.
A 10-minute reset is more effective than a short reset for F9 codes because the control board may need a complete memory clear.
Inspect the control board for visible damage
Disconnect power. Access the control board by removing the top or front panel of the DishDrawer (location varies by model). Visually inspect the board for obvious damage: swollen or burst capacitors, blackened components, burn marks, or corrosion from moisture. Any visible damage confirms the board needs replacement.
Take a clear photo of the board before touching anything. If you need to order a replacement, the photo helps confirm the correct part number.
Check board connections
If no visible damage is found, check all wire harness connections to the board. Disconnect and reseat each connector firmly. Look for corroded or bent pins. Moisture from the dishwasher environment can degrade connections over time.
Spray electrical contact cleaner on each connector before reseating it. This can resolve intermittent F9 codes caused by poor connections.
Replace the control board
If the F9 code persists after resetting and checking connections, the control board needs replacement. Note your exact model number from the rating plate inside the drawer. Order the correct replacement board, transfer all wire harness connections to the new board one at a time, and install it in the same position.
Some Fisher & Paykel control boards require programming after installation. If the new board does not operate correctly, a technician with the Fisher & Paykel diagnostic tool may need to configure it.
When to call a professional
F9 almost always requires professional service. If the code does not clear with a hard reset, contact a Fisher & Paykel authorized technician, especially if the unit is under warranty.
