    Default Whirlpool duet sport error code F28

    Model Number: WFW8410SW00
    Brand: Whirlpool
    Age: 1-5 years

    You guys are amazing! I repaired my fridge in a couple hours for free because of you're info on this site, the appliance repair guy wanted to replace parts that I didn't need to. THANK YOU!
    Now, I hope I can find help on my Whirlpool Washer Model WFW8410SW00.
    The f28 serial communication error is coming up. Do I need to take the machine apart to check if its a loose connection. thank for any help you can provide.

    Thanks, glad our site helped you fix your refrigerator.

    Yes for the F28 error code:
    First, check the wiring harness connections to the MCU, the Motor, and the CCU. Make sure all the connections are tight and there are no ground wires off. Then check the connections of the CCU board within the housing.

    If the wiring connections are fine then It would be a good idea to order both, as both components have been problematic for the error code F28.

    Here's the CCU for your model you can order:
    Whirlpool W10205842 Cntrl-Elec - AppliancePartsPros.com


    Here's the MCU for your model you can order:
    Whirlpool W10163007 Cntrl-Elec - AppliancePartsPros.com


    You may also want to remove the MCU board from its plastic casing, and look for burned/arc spots on it, we've had a few members report that. If you find yours does, just order the MCU.

    If you find either the MCU or the CCU(Microcomputer Machine Control Unit) fixed it, you can return the one that you don't need for a full refund.

    Smile Whirlpool duet sport diagrams?

    I have the technician troubleshooting guide from the front panel that shows a wiring diagram, but do you know of any guides that have more step by step info for us beginner DIY's. I think I'll need a little more detail.

    I fixed it. Now I feel like an idiot.
    After spending lots of time trying to figure it all out, and looking for loose connections I realized there was a grounding switch on the front bottom corner.
    I had the front panel off to clean out the drain. I was having a hard time getting the screws back in and I left them off. I asked my husband to put them back on (2 weeks ago) so the panel kept falling off each time it got bumped. I of coarse thought I had loosened something, cleaning it out and never noticed the stupid switch! I only had the error message some of the time (probably when the panel was on the ground) and never put 2 and 2 together.
    Thanks for your help.
