Whirlpool Duet Washing Machine Error Codes Explained

The following table is a summary of the possible error codes for the Whirlpool washing machine – and what they mean.

Error CodeWhat it Means
SUDSThere is SUD inside the drum that has to be removed
FoE1Error display to show you pressed the wrong button. Items detected in a washer in a wash cycle.
F1E1The control board of the washing machine is throwing off

F3E1There is a problem with the pressure switch
F3E2Temperature of the washing machine is below or above the optimal range
F5E1     There’s a problem with the door switch
F8E3Washer is close to overfilling and therefore shut off
FH or HFThere is a problem with water inlet. The machine has insufficient or no water supply.  
F/dLA door error occurred because the door could not lock at all 

Let’s take this even further and have more explanation for clarity.

1. F/H Error Code

When you see the F/H error code displayed on the console, it means the machine failed to detect the water entering the machine after 30 seconds.

Also, you’ll see this error if the control detects 10.5 gallons of water passing through the flow meter but hasn’t detected the pressure switch trip.

First, press the pause or cancel option twice to clear the display.

Now, if there’s no water in your Whirlpool Duet washing machine, turn all the valves at the water sources on, check the kinked inlet hoses, and verify that the inlet valve works properly.

If there’s water in the washing machine, check to ensure the drain pump works as intended and that the pressure switch hose is in good condition and properly connected to the Pressure and Tub switch.

2. F/02 Error Code

The F/02 error indicates a long drain. The error means the drain time exceeds 8 minutes, and the water valves are turned off on a hardware level. You’ll see a SUD error after the first 4  minutes, followed by the F02 error.

Press the cancel or pause option two times to clear the display. Inspect  the drain hose to ensure it’s neither kinked nor plugged.

Check the electrical connection to ascertrain that the pump is running. Also, examine the drain pump to ensure it doesn’t have any foreign object.

If none of these suggestions fixes the error, you may need to have the pump replaced. You can get the Canamax  Washer Drain Pump, which is compatible with most Whirlpool washing machines.

3. F/05 Error Code

If you see this error on your washing machine’s control panel, there’s a problem with the water temperature sensor. The machine outputs the error because the temperature NTC value is out of range.

Also, it could be that the heating element circuit failed.

We suggest that you check the water temperatures sensor, the element relay, and the heating elements to ensure they’re in good condition. Make sure the connect to the healting element, relay and the sensor is accurate.

4. F/06 Whirlpool Washing Machine Error Code

The F/06 errror code indicates a problem with the drive motor tachometer. The machine’s control system can’t detect the motor speed.

Therefore, the machine will automatically shut down. In the event that the error occurs at high-speed spin, the door will unlock after 180 seconds. 

To troubleshoot the error, check the wire harness connection betweee the drive motor and the MCU (Motor Control Unit). Also, check the connection between the Central Control Uit and the Mtoor Control Unit.

5. F/07 Error Code

The  F/07 error code indicates an issue with the Motor Control Unit. Essentially, the Cetntral Control Unit detected a short in the MCU. Should this failure occur during the high-speed spin, expect the door to unlock after 180 seconds. 

Again, you need to check the wire harness connection between the Motor Control Unit and the Drive Motor – and between the CCU and MCU.

6. F/09 Error Code in Whirlpool Duet Washing Machine

error f09

The F/09 error code in your Whirlpool Duet washing machine indicates an issue with Overflow condition.

An Overflow condition occurs if the contact on th pressure switch remains closed for more than 60 seconds.

In this scenario, the washing machine’s door remains closed and the drain pump runs constantly, even if you press the pause or cancel option twice or clear the display.

To fix this error, check the drain hose and make sure it’s not inked or plugged. Also, check the condition of the wire harness cnenctors to the Central Control Unit, Drain Pump, and Pressure Switch.

Check the pressure switch to make sure it operates optimally. Make sure the inlet valve shuts off properly. And clean foreign objects form the pump filter.

7. F/10 Error Code

The error code F/10 indicates a heat sink thermal trip. More often than not, the thermal protector on the Motor Control Unit will open the thermal protector if the heat sink gets too hot. This will stop the machine from functioning and the device will display the F/10 error. 

You can fix the F/10 error by checking for proper installation.

Also, make sure you keep the machine away from a source of heat and that where you station it has proper ventilation. Also, check the drive system for failed or worn out components and have them replaced.

8. F/11 Error Code

The F/11 isn’t an error that’s likely to happen. That’s not to say it can’t occur. The code refers to a serila cmmunication error. It denotes wrong communciation between the Central Control Unit and the Motor Control Unit.

First, check the wire harness connectors to the motor, the Central Control Unit, and the Motor Control Unit. Second, check the drive system for failed or worn components and have them replaced.

9. F/13 Error Code

If you see the error code F/13, your Whirlpool Duet washing machine has a dispenser circuit problem. The error occurs because the machine can’t drive the dispensor motor to its proper position.

For troubleshooting, check the mechanical connection fromt eh dispensor motor to its top. Also, check the wire harness connections to the CCU (Cental Control Unit) and to the dispensor motor.

10. Whirlpool Duet Washer Error Codes F21

If your Whirlpool washer displays an F21 error code, it means there is a drainage issue. The good news is that cleaning the drain filter or drain hose frequently solves the problem.

A reset should give a temporary workaround if you need to address the problem code immediately.

You’ll see the F21 code error if:

  • The drain pump is either blocked or broken and must be replaced
  • The drain pump’s drain filter is clogged or obstructed
  • The drain hose drains into a clogged or obstructed pipe
  • The drain hose is either broken or clogged

The error can also occur because a communication issue exists between the drain pump and the main control board due to a malfunctioning pressure switch.

Or the drain pump wire harness is either broken or doesn’t communicate with the main control board.

You can fix this error by: 

  • Performing a reset: Try hitting Pause/Cancel two times or performing a reset. Disconnect the electricity to the washer for 1 minute to reset it and restore the power.
  • Chec the Drain Hose: The drain line may be kinked, pinched, or hindered by a tiny object if the washer won’t drain. Also, the drain hose outlet may have immersed in water, limiting the washer’s capacity to drain. If you cannot unclog or correctly attached the drain hose, have it replaced.
  • Inspect the Pressure Switch: The pressure switch regulates how much water is in the tub and informs the control panel whether it needs refilling or draining. If you notice that the pressure switch isn’t working correctly, have it replaced.

11. Whirlpool Duet Washer Error Codes F9 E1

The E1/F9 error code indicates that the machine is taking over 8 minutes to drain. Whirlpool suggests making sure the drain line isn’t kinked or clogged, and that you’re using a high-efficiency detergent to eliminate suds.

Your washer most likely has a blocked filter, a broken drain pump or pressure switch, or loose wiring if it isn’t the drain hose or detergent. If inspecting these parts fails to resolve the problem code, the control board may be defective.

12. Whirlpool Duet Washer Error Codes F20

The F20 error code shows when no water entering the machine or when the pressure switch trip is not detected. If the F20 error occurs, the washing machine cancels the wash cycle automatically.

You wil get the F20 error if there is a restriction in  water supply due to a kink or obstruction in any of the intake or outlet hoses, a disconnected water supply, low water pressure, or a defective drain pump.

A punctured, fractured, loose, or defective pressure switch or pressure switch line may also cause the F20 error to show.

Check for kinks, twists, or other obstructions in the inlet hoses. When the washing machine is in its normal position, make sure the hoses are not crushed or kinked.

Check that the hot and cold water intake faucets are both open, and that the inlet screens are clear.

Turn off the water supply, unhook the hoses, and inspect the interior of the washing machine where the hoses connect to the machine.
