Fisher & Paykel Dishwasher Errors

Updated February 21, 2017

Error codes alert you that your dishwasher is not performing correctly. Fisher & Paykel offers drawer dishwashers with company-specific fault codes. When you receive an error code, immediately address the problem to avoid further damage to your dishwasher. If you cannot fix the problem, contact a Fisher & Paykel service person, and do not try using your dishwasher until the unit is repaired.

U Error Codes

The "U1" error code means that your Fisher & Paykel drawer dishwasher isn't filling correctly. Turn on the water supply faucets if turned off. Clean the inlet supply hose if dirty. Verify that the drain hose, spray arm and filter plate are installed correctly. Check your installation against the installation instructions in your manual. The "U2" error code indicates that you opened the dishwasher door after the cycle started. Clear the error code by pressing the "Power" button. Select the "Start/Pause" button to restart the cycle. Select the "HP" water pressure setting if you get the "U3" error code. Clean the drain pump if dirty. See if the drainage hose is correctly installed, and straighten it if kinked.

F1 and F2

The "F1" error means that the dishwasher has engaged the flood switch. Immediately shut off the dishwasher power and the water supply. The flood switch may have failed, and you need to replace it. The "F2" error code indicates that the motor is having issues or failing. Test the motor for continuity with a multimeter. If it's defective, replace it. Call a Fisher & Paykel service technician for assistance if you cannot repair these items yourself.

F3 and F4

The "F3" error code means that the temperature sensor has failed. Check the incoming water temperature. If it's hotter than 65 degrees Celsius, lower the temperature setting on your hot water heater. If your water is too hot, it can damage your dishes and cause leaks. Your temperature sensor or element is not working properly if you receive the "F4" error. You must replace the sensor, or call a Fisher & Paykel repair centre.

Other F Error Codes

All other "F" codes -- "F6" through "F9" -- mean that your dishwasher electronics are malfunctioning. The code does not indicate exactly which component is going out. Disconnect your dishwasher from the power source, and remove the main access panel. See if any wires are loose or frayed, and repair or replace these wires. Examine the control board, and see if it has any broken components or connections. It's usually difficult to repair the control board. Get a new one from a Fisher & Paykel parts dealer.
