Whirlpool Diagnostic Mode

When the washer has no stored fault codes, the seven-segment display will show '888' or '88' when entering certain diagnostic modes.

This test verifies power flow to and from the Appliance Control Unit (ACU). Failure can indicate issues with the power cord, interference filter, or connections to the ACU.

The 'Clean Washer' LED will flash at the end of a wash cycle as a reminder to run the 'Clean Washer' cycle. This reminder appears after 30 wash cycles have been completed since the last cleaning.

If the light inside the drum does not illuminate (on models equipped with one), there might be a problem with the door switch, the wiring, or the light bulb itself.

The washer displays fault codes in the format F# E#. The F# code indicates the system or category that has a problem, and the E# code specifies the exact component or subsystem that is suspected. Up to ten codes can be stored.

Excessive suds have been detected in the washer tub. The washer is trying to reduce the suds automatically. If the problem continues, it may be due to incorrect detergent usage.

The washer detected a high temperature during the wash cycle. This could be related to the water supply or the heating element.

The load in the drum is unbalanced or too large, preventing proper spinning. Avoid tightly packing the drum or washing single, heavy items alone.

There is an issue with the main relay, which controls power to various components. This typically requires replacing the ACU (Appliance Control Unit).

The Main Control Unit (MCU) is experiencing voltage that is too high or too low. This could be an issue with the household power supply.

The water level sensor is not sending a signal, or the signal it is sending is not within the expected range. This usually means the water level sensor needs to be checked or replaced.

The wash temperature sensor (NTC) has an open circuit or a short circuit. The washer may still function, but temperature control during the wash will be affected.

The dry temperature sensor has detected an out-of-range reading, an open circuit, or a short circuit. The wash function will still work, but the drying function will not operate.

The ACU cannot detect a temperature increase from the wash heater, indicating a problem with the heater relay or its feedback signal.

The washer is unable to lock the door. This prevents the cycle from starting or continuing.

The door is not opening as expected. This can occur after a cycle or when trying to manually unlock.

The ACU (Appliance Control Unit) is not receiving communication signals from the HMI (Human-Machine Interface), which includes buttons and displays.

The HMI (Human-Machine Interface) is not receiving communication signals from the ACU (Appliance Control Unit). This means the main control unit isn't communicating with the user interface.

The ACU (Appliance Control Unit) is not receiving communication signals from the MCU (Main Control Unit). This indicates a critical internal communication failure.

This error code indicates that the system believes the motor has become disconnected. This is usually related to the wiring or the motor's electrical connection.

This code suggests that the motor control unit is experiencing an overload condition. This could be due to excessive load on the motor or an internal component issue.

This error indicates that the main motor control unit has overheated or experienced an over current condition. It could also mean there is an internal failure within the unit.

This error code signifies that the main motor has overheated. This can happen if the motor is working too hard or has an internal issue.

This error means the motor is unable to turn, often referred to as a locked rotor condition. This could be due to a physical blockage or an electrical issue.

This error code indicates a problem with one of the water inlet valves. The machine may not be filling correctly or at all.

This error means the water level sensor has detected that the machine has overfilled with water. This could be due to a faulty valve or sensor.

This error indicates that the machine is taking too long to drain the water. This usually points to a blockage in the drain system.

If the display starts flashing while you are performing the Human-Machine Interface Test, it indicates that an active fault code is currently detected by the washer. Only one such code is displayed at a time.

If the seven-segment display begins flashing while you are in the Quick Diagnostic Test mode, it means the washer is currently detecting an active fault code. Only one active code can be shown at a time.

The Appliance Control Unit (ACU) has a status LED. After power-up, a rapid blink followed by a slow blink (0.5 seconds on, 0.5 seconds off) indicates that the microcontroller and its power supply are functioning correctly.

Water escaping from the washer can be caused by various issues, including loose hoses, drain problems, overloading, or internal component leaks.

The washer is not producing beep sounds for button presses or cycle completion. This could be a setting issue or a fault with the speaker or control unit.

If you press buttons on the control panel and do not hear any sound feedback, it's possible that the button sound feature has been turned off in the settings.

This indicates that the washer is not receiving power or the main control interface is not functioning. This prevents any lights or displays from activating.

The control panel lights, display, and buttons are not turning on. This indicates a power issue to the Human-Machine Interface (HMI) or a fault within the HMI itself.

If clothes are not drying properly, it typically points to a problem with the drying heating element, the temperature sensor, or the blower motor.

Suboptimal washing results can be due to excessive suds, incorrect water levels, improper loading, or using the wrong detergent or cycle.

This LED flashing indicates that the required temperature for the sanitize cycle was not reached. This could be due to issues with water supply or the heating element.

Individual buttons on the control panel are not lighting up as expected. This suggests a specific issue with the Human-Machine Interface (HMI).

Excessive vibration or unusual noise during operation can stem from installation problems, loose components, or issues with the washer's suspension system.

The washer door is not locking, which prevents cycles from starting. This could be because the door isn't fully closed or the lock mechanism is malfunctioning.

The washer door cannot be unlocked, preventing access to the drum. This might be due to a misaligned latch or a malfunctioning lock mechanism.

The drum is not spinning, either during the wash or spin cycles. Check the door lock, look for obstructions, and verify the motor and its connections.

The control panel (HMI) is not registering button presses or selections. This could be a control lock issue or a problem with the connections or the unit itself.

The motor is overheating during operation. This could be due to mechanical friction or a fault within the motor itself.

The washer is filling with too much water. This is typically caused by a blockage in the drain system or a problem with the water inlet valves or water level sensor.

Detergent or fabric softener is not being dispensed into the wash. This could be due to a clogged dispenser, water supply issue, or a faulty valve.

The washer is not draining water. Check the drain hose, pump filter, and the drain pump itself for any blockages or faults.

The washer is not filling with water, or the water level is too low. Check water supply, filters, hoses, and the water level sensor.

The washer shows no signs of power. It won't turn on, respond to button presses, or display any lights or information.

The washer does not start a cycle when the 'Start' button is pressed. This could be due to the control lock, door mechanism, or communication issues.
