    I found the same information about f06 on the tech sheet in the machine. It does not give information as to how you go about checking the mcu or the tachometer. Can you give me any info that I can use to definitely pinpoint what part is causing the problem. As you know, these parts are expensive and guessing makes me a little nervous about the possibility & consequences of guessing wrong. thanks -- Jerry

  • Tippycanoe51 May 20, 2008

    I am trying to get test points & values. I own & use a vom daily. What I need is technical data to confirm the readings. I have not had good luck being a parts replacer.

  • Tippycanoe51 May 23, 2008

    No, but I did replace the motor/tachometer. Worked ok during the 1st cycle while I was there, but got a call this a.m. saying its back to f06 again. Since no one has any info on diagnostic procedures, I guess I'll just have to do this trial & error thing. I am ordering a ccu. If you find any more info on check out procedures, I would still like to know for future reference. Thanks - Jerry

  • Tippycanoe51 May 28, 2008

    Another bad guess! Replaced the ccu - customer called back with the f06 code again. Must be a better way to go about this than putting on a series of $150 parts until the thing works. I am ordering the mcu tomorrow. I really think a refund is in order for your service. What do you think? I mean, I haven't gotten any information that didn't come with the machine & I've lost the time it's taken to communicate with you. Your bet was wrong with my money on the table.

1. First instead of just unplugging the machine, try switching the circuit breaker for that socket off for about 10minutes and see if that resolves the issue. Also pull out the detergent dispenser and reach all the way in to the back there is a small plastic flapper valve. Move it from side to side with your finger this will rest code.

2. If that does not work, check the drain pump..it could be clogged. All you do is take off the bottom front panel (there are 3 screws). After the panel is off, there is a turn knob right in front in the middle. Simply unscrew it and remove any thing in the "catch". Screw back (re-attach) the knob and you are good to go.

3. In the manual, the instruction for an F06 code (electrical problem) is :

Select PAUSE/CANCEL twice to cancel the cycle. Select DRAIN/SPIN if there is excessive water in the washer. Re-select cycle and press START. If the problem remains, call for service.

After that, you might try unplugging then plugging it in again.

The F06 code is generally an electrical fault. · Check wiring to motor and replace drive motor if necessary. Check the wire harness that goes to all your connectors on the Motor, MCU, and CCU. I have seen a loose wire connector do this F06 error.

If all checks ok, then its likely a faulty CCU, check your owners manual, some are covered under warranty for up to 5 yrs.

Here is the one for your model:

    Ok, it seems that your particular model is manufactured by Whirlpool. Heres what I came up with on the F06 code:
    Drive
    Motor Tachometer Error


    The
    control is unable to properly detect motor speed and the
    machine will shut down. If a failure occurs during high-speed
    spin, the door will be unlocked after 3 minutes.

    Resolution:


    • Check
      wire harness connections between the Drive Motor/Tachometer
      and the Motor Control Unit (MCU), and between the MCU
      and the Central Control Unit (CCU)

    • Check
      the Drive Motor

    • Check
      the MCU

    • Check
      the Wire Harness



  • Swilin Sampson

    Basically , you have to check for continuity using an Ohmeter/voltmeter.

    HERE is a good guide..


  • Swilin Sampson
    Swilin Sampson May 28, 2008

    Try to remove and reinsert
    all wire connections at the board and motor. This tends to clean the
    small mount of corrosion that will build up on the connections. After
    you do this put the machine into a service cycle. The instructions on
    this is in the tech sheet. Part of the service
    cycle is running the motor at certain set speeds which checks the tachometer.
    Good Luck!

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.

I have a kenmore elite 3 that flashes f06


"F06" is a Motor Speed error code. This could indicate a problem with the drive motor, motor control unit (MCU), interconnecting wiring, or the tachometer (part of the MCU). The following link explains:

http://www.fixya.com/support/r714929-f06_error_whirlpool_duet_kenmore_elite

I would begin by checking all the wiring and connector plugs between the MCU and drive motor. Vibration from the washer can cause the connectors to come loose. Also check them for any signs of corrosion that may be causing poor contact.

Measure the motor windings to see if they are still within specs. Bad motor windings could generate the error code as well.

Read through the link provided and let me know if you have any questions. I hope this helps you.
