WFMC2201UC Bosch Washer: Technician Brian, Please help!

[gergrff]

Technician Brian, you are my last hope for help on my repair. I paid to
   become a member of one forum and then posted on two others,
   and I still need help - probably because it is a Bosch!
This washer is only two years old. the symptom is the clothes come out
   too wet for the dryer. You can do a manual spin with this machine at
   1000RPM, then the clothes can be put in the dryer.
I was able to get a service manual that would apply to my machine -
   does not say my model number on manual), but was told it does apply
   to my machine.
I checked the pump sump that is accessible from front of machine - no
   problems there. I checked the flow of the discharge line - strong flow
   out of unit. Machine spins smoothly with and without a load.
More info on next post...

More info on Bosch washer:
I pulled the trouble codes as the manual described - Results are E:20 -
   spinning aborted due to unbalanced load; d:08 - motor speed sensor    
   failed; d:10 - power limiter switch off.
The unit failed the P:04 test - Machine would not follow the test
   procedure for the low speed testing and turning the drum CCW and
   CW for the times and order the manual stated.
Unit did do the 1000RPM at the end of the test properly.
Whenever I scrolled through the trouble codes the unit would skip the
   following every time: jumps from E:24 to d:08, then skips d:09, then
   skips d:11-d:18.
During a normal cotton cycle the unit only spins at 1000RPM for a few
   minutes during a one hour cycle.
I am leaning towards the motor control board and/or the motor speed
   sensor.
Any help would be appreciated, an educated guess or opinion?
Thanks, GG

Here's an 'educated' guess...

You probably need a new motor control. If the machine performs only on the top speed but will not do the lower opnes, the board is suspect. This is what happens on most of the other brands as well.

I am with Repair-man on this one.  The motor controller is responsible for motor operation and interfaces with the main board to provide feedback from the motor.  It is possible the main control could be causing the problem, but the motor control is the more logical failure given your test results.

Technician Brian, thanks for the reply and recommendation.
I feel better now about buying the motor control board.
Thanks again for your help,          GG
