Bosch WFVC6450UC/27 Washer Won't Spin

[red95gts]

Hello!

I have a nearly-5 y/o Bosch WFVC6450UC/27 Vision 500 series Front Load Washer that is not spinning.  I've looked in Error Log and found:

- E20: Spin Cycle Terminated - No communication between control & inverter, Unbalance too high - check wire harness - check load

- DR10: Power limiter switch off - Too heavy load, mechanical friction - check load, check oscillation system - check gasket

- DR11: Voltage too low - Weak power supply - check line voltage

- DR20: IGBT power stage short circuit - High current - replace inverter.

Every one of those error codes points toward test program 04, which I've attempted to run numerous times.  I can hear the drain pump run, but the drum never spins and it eventually times out with an E20 error.  The drum spins freely & easily by hand, belt looks good and it's still attached, and when I turn the drum I can see the commutator of the motor turn.  Starting to look like either a bad motor or a bad main control board....

The story (as told my my beautiful, yet highly non-technical wife), is that she loaded a queen size comforter in the washing machine, started a cycle, and walked away.  She came back to a comforter that was soaked along the bottom, yet still mostly dry up top, and a cycle that did not finish.  She doesn't recall what the display was when she opened the washer.  

- Would someone be so kind as to PM me the service manual for the WFVC?  Anyone know the expected resistance on each of the phase windings of the motor?  Any fuses on the Main Control board?  Any words of wisdom, general info, or witty insults in regards to this problem?

Thank you, Master Samurai!

Update - No fuses or any visual signs of damage on the main control board.  Motor windings measure 6.7ohms each - no variance between phase windings.

Service manuals are available with the Professional Appliantologist package.

I would check the wiring between the main control and the inverter for continuity.  And also between the inverter and the motor.
