hey there, i'm a little new to this forum and i havent found the answer to my problem so far...

i have a whirlpool duet sport washer that just wont work!

i power it on, powers on fine. i choose the cycle i want, press "start" and the door locks. normal... but then it stays locked and the "door locked" light stays red...

when i press "cancel", the lights flash like normal but the door stays locked and i have to manually unlock it all the time. and on top of that, it wont turn off at that point. no matter how many times i press the "power" button, it just stays the same and nothing works until i unplug it from the wall and plug it back in... and it goes on and on and on...

i replaced the door lock actuator, thinking that was it, but that didnt fix it...

what could it possibly be???

also the model number is: WFW8410SW01, Serial #: HLU1581812

Possibly a MCU (Motor control unit.)

Try this:

- Disconnect the M13 connector from the CCU (Central Control Unit) that is located under the main top, front right side.

- Then try a cycle. It should lock but then not go any further ... if you leave it long enough you will get an error code. You don't have to wait for that though.

- Now try hitting the cancel button - if it unlocks, then you have a MCU problem - replace the MCU.

- If not, then it could be a pressure switch issue, or a CCU issue.

Let us know if it is NOT an MCU and we can work further on it.

so its the motor control unit thats messed up? because now the "door locked" light doesnt even light up... i reconnected the m13 connector and after i try to start a cycle, it makes the door locking sound like 6 times and says F-22... which is the door lock mechanism, correct?

aghhhh i'm so confused. these things are aggravating!

You ask that just because the MCU happens to be circled in one of the pics I posted? You asked where the CCU is located, each of those pics shows you.

It is not expedient to be so easily confoosed when embarking on an appliantological journey, Grasshoppah!

woops, the door lock actuator was unplugged from the bottom... how stupid of me...

ok so back to square one:

i repeated your steps, Strathy... disconnected M13, turned it on, pressed start, the door locked, and i'm waiting for an error code... its been 5 minutes no and still no error code...

so i pressed cancel and it didnt unlock, the "add a garment" light keeps flashing and we're back to the same exact problem i've been having from the get-go.. i have to manually unlock the door and then unplug it to shut it off..


any ideas?

Ahh, Grasshoppah, you have snatched the pebble from Master Strathy's wizened hand and have proven that the MCU is indeed the problem.

Click it to git it, Hoss...

Comes with a one year warranty. And if, by some freak of nature, it doesn't fix your problem, return it for a refund.

nevermind.. waited long enough to see "F28" ... apparently thats a serial communication error, between the CCU and MCU?

F28 error usually results from running the unit without all the panels in place, see this page for more.

If you wanna be doubly-woubly sure, repeat the procedure while singing along with this page. Replacing the MCU ain't so bad, I even posted how-to destructions for you on that page. Posted Image
