Whirlpool Dishwasher Fault Codes

If your Whirlpool dishwasher is not draining, not cleaning dishes properly, or experiencing other malfunctions, specific error codes can indicate the underlying issue. While error codes may vary by model, the most frequently encountered ones and their meanings are listed below.

Error Code F1: Temperature Sensor

This error typically points to a temperature sensor malfunction. The water temperature may be either too low (below -3°C) or too high (above 85°C). A faulty NTC temperature sensor is often the cause and may require replacement.

Error Code F2: Water Leak

If your Whirlpool dishwasher displays error code F2/E2, it has detected a water leak. To resolve this, drain the base, locate the leak, and make necessary repairs. Alternatively, a malfunctioning main control board may be at fault and require replacement.

Error Code F3: Heating System

This error indicates an issue with the heating system, causing the dishwasher to either not heat at all or heat too slowly. Potential culprits include a defective heating element, a faulty temperature sensor, or poor connectivity between the control board and the heater.

Error Code F4: Drainage System

A properly functioning drainage system ensures efficient water removal. Blockages or kinks in hoses and pipes can lead to drainage problems. Cleaning or replacing the pump or filter is recommended. If the drain hose is too low, the issue may stem from an optical sensor or control board failure.

Error Code F5: Rotor Blocked

This error suggests that the motor rotor is jammed or malfunctioning, potentially requiring motor replacement.

Error Code F6: Water Supply Issue

Error code F6/E6 signifies improper water flow or a lack of incoming water despite an open inlet valve. The issue may stem from a clogged inlet hose, a defective inlet valve, or a faulty flow meter.

Error Code F7: Flow Meter Malfunction

Closely related to F6, this fault may arise due to a blocked or kinked water inlet hose, a faulty inlet valve, or a closed water tap.

Error Code F8: Excess Water Level

When the dishwasher detects an excessive water level, a blocked filter may be preventing proper drainage. Additional causes include a malfunctioning water inlet system, excessive detergent foaming, or a spray pump failure linked to the main wash rotor.

Error Code F9: Continuous Water Inlet

This error can be attributed to either a defective water inlet valve or a malfunctioning control board, necessitating a replacement.

Error Code F0/F10: Sensor Failure

A communication failure between sensors and the main control board can trigger this error. Professional assistance is recommended for proper diagnosis and repair.

Error Code FA: Optical Water Indicator (Turbidity Sensor)

This error occurs when the turbidity sensor detects inconsistencies, such as dirty water or excess detergent foam. If dirt obstructs the sensor, the error may persist until cleaned or replaced.

Error Code FB: Motorized Diverter Valve

A faulty diverter valve, responsible for regulating water flow to the upper spray arm, may need replacement.

Error Code FC: Water Hardness Sensor

This sensor monitors water hardness and alerts you if additional dishwasher salt is needed. If the error remains despite adding salt, the sensor itself may be defective and require replacement.
