My wife loved the Whirlpool Duet washing machine when she first got it, but now I think she would be happy to push it off of a cliff. We haven't even had it 2 years and about once a week it stops working in mid cycle. It beeps, flashes F11 error code, stays locked and there is no way to unlock it to get the wet clothes out. We have tried unplugging it to reset it. Sometimes this method works but sometimes it doesn't and when that happens, the wet clothes are stuck inside the machine...sometimes overnight. We've called the repairman a couple of times ($50 a pop) to unlock the door and get it started again. The repairman told me this is an extremely common problem with the Whirlpool Duets. Some of the computer units must have been faulty. It's hit or miss for those of you who are thinking about purchasing this and the problems usually start after the first year or two.
TIP: If your machine displays this error code and it is within the time period of your warranty, get the CCU replaced ASAP. Don't let Whirlpool stall while your warranty runs out. You should have a 1 or 2 year warranty which covers electronics.
We have to buy a new door lock and have the CCU replaced. The problem is that the new part is not guaranteed...not even for one day so if we get another faulty unit, we'll have the same problems again after a year of use.
Starting to see these fault codes pop up in these otherwise fine machines. The F/11 code is just a generic code generated when there’s a communications error between the two main control boards in the washer. These two boards are the Motor Control Unit (MCU) and the Central Control Unit (CCU).
A common problem is the wiring harness jiggling loose; remove and reseat it and that usually fixes it. If not, then you’re looking at spending some money on control boards. Yes, I said boards, plural. The really sucky part is that there’s no way to definitively and conclusively prove which board, the MCU or the CCU, is at fault so, unfortunately, that only leaves trial and error.
It means your motor has some misconnection signal between the motor, the MCU (motor control unit) and the CCU (Center control unit). Most of the case, the sensor inside the motor getting bad, you need to replace the whole motor.

• Check Wire Harness connections to the MCU, the motor, and Central Control Unit (CCU) • Check the Drive system for any worn or failed components • Check MCU • Check CCU • Check Motor • Check Wire Harness
Replace failed component.

A call with the Miele tech helpdesk got me an answer: The tacho unit (coil) should have about 500 Ohm resistance, so they told me. My unit only had about 78 Ohm's, so I ordered a new brush unit (which includes the tacho). The new unit actually measures 250 Ohm, but since it was a new one I did fit it. It works like a charm again. No F53 fault code anymore. The part no. is 6799642 - Module BSTV Mrt40 RK473. It cost me about 70 euro's including shipping. My machine is a type W3821, but the motor and brush unit with tacho is used on a variaty of models. Cheers!
The Central Control Unit has detected a short in the motor control unit. If a failure occurs during high-speed spin, the door will be unlocked after 3 minutes.
* Check wire harness connections between the Drive Motor and the Motor Control Unit (MCU), and between the MCU and the Central Control Unit (CCU) * Check the MCU * Check the Drive Motor * Check the Wire Harness
Note - Disconnect the Power Supply for Few minutes, say 30 minutes and then Turn ON the machine.If you still see the same message, better to Call a tech rather than spending many dollars on an expensive part.
F11 appears to be a Serial Communication error (a digital signal problem between the motor, motor control unit, and the central control unit). Look for loose connectors on each of these items. The wiring harness may be at fault, or any of the above devices (sounds expensive). Good luck!

Can't tell you about your particular model, just some generalities: Unless the shock actually failed from a defect, you might have broken or damaged something else. Check especially for wires or other parts pinched between the tub and other parts or the housing. Also, make sure the tub shaft hasn't broken or worn the seal at the rear or the seal at the front. If this unit has ballasts one of them may have broken or broken loose to cause the shock to break. I had one similar with that problem. Might want to take the ballasts off the tub or brace it to keep from stressing the bearing and seals. Mine had three ballasts, one large cast iron one on top of the tub and two concrete ones either side.One of the concrete ballasts broke and the tub vibrated and pinched wires and damaged seals and was totaled. If nothing but the shock is broke, it's probably worth repairing.However, the other shocks also have the same amount of wear, check them carefully first. Also, check the seals while you're in there. Use a digital camera and take pictures of everything before you take it apart and be very careful with wire routing.Most parts are held with (probably) metric and Phillips.Always unplug it to work on it and plug it into a ground-fault protected circuit.Best to set the machine up to run then plug it in remotely if possible.
