Tip & How-To about Washing Machines

F06 Error Code

This advice is for Kenmore Elite and Whirlpool Duet FRONT LOADER washing machines displaying the "F06" error code. The error is an indication a motor speed problem. You will need to check the following:

- Check the wiring harness. Verify all connections between the Drive Motor, Motor Control Unit (MCU), and Central Control Unit (CCU).

NOTE: The MCU is a circuit board located in the vicinity of the Drive Motor on the bottom rear of the washer. To access the MCU, you will need to remove the back panel of the washer.

NOTE: The CCU is the main computer for the washer and is located behind the wash tub. You will need to remove the top panel to access the CCU. This is accomplished by removing the three screws in the back of the washer that hold the top in place. Once the screws are removed, the top panel will slide back, then lift off.

- Check the Drive Motor. Perform a continuity check of the Drive Motor windings. Remove the connector plug and check across pins 1 to 2, 2 to 3, and 1 to 3. All readings should be approximately 6 ohms. HINT: You can also take this reading by removing connector 2 from the MCU and measuring across pins 1, 2 and 3. If the readings are good, this will also prove the wiring and connector good.

- Check the MCU. The connectors are numbered 1 to 3 (L to R). That is, with the MCU installed, connector 1 is on the bottom, followed by 2 in the middle, and 3 on top.

Connector 1 - is the serial communications link between the MCU and CCU and has three wires. At the opposite end, this will be the 2nd connector from the rear on the left-hand side of the CCU.
Connector 2 - is the link between the MCU and the Drive Motor. Pins 1, 2, and 3 on this connector are the Drive Motor windings. Pins 4 and 5 are for the tachometer.
Connector 3 – is the primary power connector. Pins 1 to 2 should read 120VAC with the door in the locked position. Pin 3 is ground. At the opposite end, this is the 4th connector from the right on the front of the CCU.

NOTE: All the connector pins are numbered R to L.

If your continuity readings are normal for the Drive Motor and you have verified all connectors, replace the MCU.

If any of the Drive Motor windings indicate readings higher that 6 ohms, replace the Drive Motor.

I hope this information is helpful.

The "F06" fault code indicates a drive motor error. This means the control is unable to properly detect motor speed and the machine will shut down.

F21 Error Code on Whirlpool Duet & Kenmore Elite Front Loader Washers


This helped my husband fix our washer. We had 5 baby socks clogging up the washer from draining. I guess we will need to use a laundry bag to wash little baby things.

What does the F06 error code on the Kenmore Elite HE3 washer mean?


Hi


Thanks for using FixYa. Error F06 in your whirlpool duet indicates that the control is unable to properly detect the motor speed and so the washer shuts down. This usually occurs during high speed spin and the door will be unlocked after 3 minutes. To resolve this issue you’ll have to check the wire harness connections between the Driver motor and the Motor control unit (MCU). If that is fine then check the connection between the MCU & central control unit (CCU), replace the part that has gone bad. Please do rate the solution if the issue is resolved or post a comment for further assistance.


Thanks

F06 Error On Whirlpool Duet & Kenmore Elite Front Loaders


Good directions. Thanks.

However I tried just unplugging the washer for a few minutes first and that seems to have fixed the problem for now. Its worth trying before taking anything apart. (Or in my case, unstacking)
