  • Check the Pump: Ensure it is not leaking and replace it if needed.



F5 or E5: Overfill

Description: This error means that there is too much water in the dishwasher, which can be caused by a faulty float switch or fill valve.

Troubleshooting:

  • Check the Float Switch: Ensure it is moving freely and not stuck.

  • Test the Fill Valve: Replace it if it is not functioning correctly.

F6 or E6: Water Tap Closed

Description: This error indicates that the water tap is turned off or there is insufficient water supply to the dishwasher.

Troubleshooting:

  • Ensure Water Tap is Open: Make sure the tap is fully open.

  • Check Water Pressure: Ensure that the water pressure is adequate for the dishwasher.

F7 or E7: Flow Meter Problem

Detailed Troubleshooting Steps

Water Supply Issues

If your Whirlpool dishwasher displays an F1 or E1 error code, start by checking the water supply. Ensure the water tap is fully open and the inlet hose is not kinked or blocked. If the water inlet valve is defective, it may not allow water to enter the dishwasher. Use a multimeter to test the valve for continuity and replace it if necessary.

Drain Issues

For an F2 or E2 error code, the problem is usually related to drainage. Check the drain hose for kinks or blockages. Clean the filter at the bottom of the dishwasher, as a clogged filter can prevent proper drainage. Listen for unusual noises from the drain pump, which may indicate it needs to be replaced.

Heating Issues

An F3 or E3 error code indicates a problem with the heating system. Use a multimeter to test the heating element for continuity. If the element is defective, replace it. Also, check the thermostat to ensure it is functioning correctly. If the thermostat is faulty, replace it.

Leakage Issues

There is likely a water leak if you see an F4 or E4 error code. Inspect the seals and hoses for any visible signs of damage. Replace any broken seals or damaged hoses. Check the pump for leaks and replace it if necessary.

Overfill Issues

An F5 or E5 error code indicates an overfill problem. Check the float switch to ensure it is moving freely and not stuck. Test the fill valve to ensure it is functioning correctly. Replace the fill valve if it is defective.

Water Tap Issues

For an F6 or E6 error code, ensure the water tap is fully open. Check the water pressure to ensure it is adequate for the dishwasher. If the water supply is insufficient, the dishwasher will not operate correctly.

Flow Meter Issues

If you encounter an F7 or E7 error code, inspect the flow meter for blockages or damage. If the flow meter is faulty, replace it. The flow meter measures the amount of water entering the dishwasher and is crucial for proper operation.

Turbidity Sensor Issues

An F8 or E8 error code indicates a problem with the turbidity sensor. Clean the sensor to remove any debris or buildup. If the sensor is not functioning correctly, replace it. The turbidity sensor detects the cleanliness of the water and ensures optimal washing performance.

Diverter Valve Issues

For an F9 or E9 error code, inspect the diverter valve for blockages or damage. If the valve is stuck or not operating correctly, replace it. The diverter valve directs water to different spray arms, ensuring thorough cleaning.

Motorized Diverter Issues

An FA error code indicates an issue with the motorized diverter. Check the diverter motor to ensure it is receiving power and operating correctly. If the motor is faulty, replace it.

Communication Errors

If you encounter an Fb error code, there is a communication problem between the control board and other components. Inspect all wiring and connections to ensure they are secure. If the issue persists, the control board may need to be replaced.

Door Switch Issues

An FC error code indicates a problem with the door switch. Ensure the door latch is engaging properly. Test the door switch to ensure it is functioning correctly. Replace the door switch if it is faulty.

Control Board Issues

An Fd error code signifies a failure in the main control board. Inspect the control board for visible signs of damage or burning. If the control board is faulty, replace it.
