Whirlpool Dishwasher Codes

Because there is a diverse range of Whirlpool dishwashers on the market, the error or fault codes will appear in varying formats based on the specific model you possess. If your dishwasher is equipped with an LCD screen, the fault code will be presented as follows:

In cases where your dishwasher features only a row of lights, the fault code will be conveyed through the start light flashing multiple times, followed by a brief pause, and then repeating the sequence. For instance, if your dishwasher were to encounter fault F7, the start light would flash seven times, briefly pause, and then repeat this pattern seven times, and so on.

Fault Code F1 or One Flash

Reason: The issue stems from a malfunctioning NTC (temperature sensor) or thermistor. This error code is triggered when the sensor detects a temperature that falls outside the dishwasher’s operational temperature range, which typically ranges from -3°C to +85°C. The primary culprit for this issue is often a defective NTC.

Solution: In most instances, replacing the NTC should resolve the problem. During the winter months, it’s possible for the dishwasher to freeze, causing the NTC to correctly sense that it’s too cold for the appliance to function. To address this, you can thaw the dishwasher by adding some warm (but not boiling) water to it and then attempt to run a cycle again.

Fault Code F2 or Two Flashes

Cause: The dishwasher has identified a water leak.

Action: Typically, you’ll need to locate the source of the leak and make the necessary repairs. As long as the dishwasher continues to detect a leak, the water valve will remain closed, preventing the dishwasher from filling with water. If there is no apparent evidence of a leak, the error might possibly be due to a malfunctioning float switch, inlet valve, or drain pump.

Fault Code F3 or Three Flashes

Cause: There is a problem with the water heating system. This error will be shown if the dishwasher cannot reach the necessary water temperature within the first 25 minutes of the wash cycle.

Action: This issue is often associated with a malfunctioning heating element, so it’s advisable to begin by testing it using a multimeter if possible. Other potential causes could involve the NTC (temperature sensor) or thermostat.

Fault Code F4 or Four Flashes

Cause: The dishwasher is experiencing drainage problems.

Action: Start by inspecting the filters in the dishwasher basin for any blockages, as this might offer a straightforward solution. If the issue persists, it is likely related to a blocked or malfunctioning drain pump.

Fault Code F5 or Five Flashes

Cause: The spray arms are obstructed, clogged, or not functioning correctly.

Action: You can address this issue by removing the spray arms from the dishwasher and cleaning them in the sink to remove any buildup or debris (using a descaler can help with stubborn deposits). During this process, you can also run a short dishwasher cycle without the spray arms to clear any additional blockages.

Fault Code F6 or Six Flashes

Cause: The problem arises when the dishwasher does not detect any incoming water even though the water inlet valve is in the open position.

Action: Start by verifying that your water supply is turned on. Examine the water inlet hose to ensure there are no kinks or blockages. If these checks do not resolve the issue, it is possible that you have a faulty inlet valve or flow meter that may need attention.

Differences Between Whirlpool Dishwasher and Bosh Dishwasher

Whirlpool

Whirlpool dishwashers offer a range of features, including sensor-based cleaning and adjustable racks, but the level of sophistication in features can vary among models.

Bosch

Bosch dishwashers are often praised for their superior cleaning performance and advanced features, such as precision spray arms, adjustable racks, and specialized wash cycles.

Alternative to Whirlpool Dishwasher

Miele

Miele is a luxury appliance brand known for its high-end dishwashers. They are known for their precision engineering, quiet operation, and advanced wash systems.

Fault Code F7 or Seven Flashes

Cause: A problem with the flow meter has been identified.

Action: Flow meter issues are not uncommon in Whirlpool dishwashers, and resolving it may entail replacing the flow meter (typically located behind the right-hand side panel). However, before proceeding with a replacement, it’s advisable to inspect the inlet valve and inlet hose to rule out any simple water supply problems as the root cause of the issue.

Fault Code F8 or Eight Flashes

Cause: A Water Turbidity Fault has been triggered, indicating that the dishwasher has detected water that is excessively dirty or turbid.

Action: Many models are equipped with both mechanical and optical water indicators to measure turbidity. To address this issue, conduct a comprehensive cleaning in and around the filters located in the dishwasher basin. The optical indicator, often resembling a small black grid, can also be found in the dishwasher basin; clean it gently, being careful not to cause any damage.

Fault Code F9 or Nine Flashes

Cause: The water inlet valve remains open, leading to an overfilling of the dishwasher.

Action: First, inspect the water inlet valve to see if it’s stuck open due to any obstructions or faults. If it appears to be in good condition and not jammed, the issue might be related to a faulty control board rather than the valve itself. In such cases, the control board may require replacement.

Fault Code F0 or Ten Flashes

Cause: A sensor fault or failure has occurred. It’s important to note that this code is typically only displayed during the service test program and is unlikely to be encountered by regular users unless they are service engineers or technicians.

Fault Code FA or Eleven Flashes

Cause: The optical water indicator is detecting elevated levels of water turbidity.

Action: For additional details and guidance on addressing this issue, refer to fault code F8.

Conclusion

In conclusion, understanding and interpreting Whirlpool dishwasher error codes is essential for troubleshooting and maintaining your appliance’s optimal performance. These error codes provide valuable information about potential issues within your dishwasher, ranging from water-related problems to sensor malfunctions.

When faced with a Whirlpool dishwasher error code, it’s important to consult the manufacturer’s manual or documentation specific to your dishwasher model to pinpoint the exact cause and recommended actions. In many cases, addressing these issues promptly can prevent more significant problems and potentially costly repairs.

Remember that some error codes may require professional service or the replacement of specific components, while others can be resolved through basic maintenance and cleaning. Regularly checking and cleaning filters, inlet valves, and sensors can go a long way in ensuring your dishwasher operates smoothly.
