Fisher and paykel dishwasher f4 error code

For anyone who owns a Fisher and Paykel dishwasher, there may come a time when you encounter the F4 error code flashing on your dishwasher’s display. This scenario can be frustrating, but it is important to understand what this code signifies and how to troubleshoot and repair the issue.

The Fisher and Paykel brand is known for manufacturing high-quality, durable, and efficient home appliances, including dishwashers. These units are designed with advanced features and sophisticated diagnostics systems, enabling them to notify the user about any malfunctions by displaying specific error codes. One such error code is F4.

The Meaning of F4 Error Code

The F4 error code on a Fisher and Paykel dishwasher generally suggests that the temperature sensor or thermostat in the unit has malfunctioned or is faulty. This part of the dishwasher monitors and controls the temperature within the device during various stages of the dishwashing cycle, such as heating the water for washing or drying the dishes.

When the thermostat fails or is not working correctly, the dishwasher cannot maintain the optimal temperature for effective dishwashing, which triggers the F4 error code. This issue can result in the dishwasher not cleaning the dishes properly or causing issues with the drying function.

Diagnosing and Troubleshooting the F4 Error Code

The first step in diagnosing the F4 error is to verify whether the thermostat or temperature sensor is indeed faulty. This process may involve disconnecting the dishwasher from the power source, removing the panels, and using a multimeter to check the sensor’s resistance. Keep in mind that these steps require a certain level of technical knowledge and may be best left to a professional appliance repair technician to prevent any further damage or voiding the warranty.

If the temperature sensor or thermostat is not faulty, other potential issues might be causing the F4 error code. These can include a malfunctioning heating element or control board. In such cases, further diagnostic tests are required.

Repairing the F4 Error Code

If the thermostat or temperature sensor is found to be faulty, the only solution is to replace it. Unfortunately, these components are not typically repairable. However, replacement is a straightforward process that many homeowners with basic DIY skills can accomplish.

When ordering a new temperature sensor or thermostat, it’s essential to ensure you get the correct part for your specific Fisher and Paykel dishwasher model. Using an incorrect part can lead to additional issues or not resolve the F4 error code.

If the problem isn’t with the thermostat or temperature sensor but lies with the heating element or control board, these parts may also need to be replaced. As these components are more complex, a professional technician should perform the repair.

Preventing the F4 Error Code

Although you cannot entirely prevent the F4 error code from appearing, regular maintenance and servicing of your Fisher and Paykel dishwasher can extend its lifespan and minimize the chance of error codes popping up. This regular check can include cleaning the filter and spray arms, ensuring the heating element is free of mineral buildup, and inspecting the thermostat or temperature sensor for any visible signs of wear or damage.


In conclusion, the F4 error code on a Fisher and Paykel dishwasher is an indication of a problem with the thermostat or temperature sensor, and it needs immediate attention. While you can troubleshoot and possibly fix the issue yourself if you are comfortable with appliance repair, consider hiring a professional to ensure the problem is correctly diagnosed and repaired. Regular maintenance and servicing of your dishwasher can also help prevent this and other error codes from appearing, ensuring you get the most out of your appliance.
