MAH6500AWW  purchased Aug 2005  Ser. 37674516GA 

I'm looking for more info on TS (troubleshooting) components machCB and  motorCB

I have '98 Service manual, 157 pages including revisions thru Feb 2001
found some files on service matters but none with board measurement s for MachCB or MotorCB hope someone knows where

to find those or other TS-troubleshooting methods

Sneaky Lr? intermittent?

I checked most crimps and connectors on lower part of washer
unbalance swithes all OK (NC)
Cleaned rebuilt drainpump
Ran through applicable tests some more confusing phase measurements of motor changed order found proper ones after found rolled app sheet wrapped in the wiring to the MachCB in the header
Tried motor test that led to MachCB Motor tested OK MotorCB had 120vac so it said to look at MachCB for faults /replacement
Resoldered leads on MachCB corner populated with 8 1/4 watt resisters fashioned heat sink to save repetition of cracked solder (see picture) points
on input test ? pressing the spin button give me jumping Led readouts from 20-30s rest all were passing
Left lower cover off to visually check motor running NOT running, no Lr code stored
Yes Motor is not running phase loops tests are passing
would like to repair boards/wiring

Motor- my lable-   Pn 6 2724148   model AHV 2-42-P-09    made in France

Need TS guide with measurements on MachCB (Machine Control Board 2201266, 22004447, 22004486 believe I have the first ) to test components etc on board. Somebodies bound to be rebuilding these, cause there are no new ones being made.
found some files on service matters but none with board measurements for MachCB or MotorCB hope someone knows where to find those or other TS-troubleshooting methods
Purchasing new expensive parts for T/E not in the budget at this time
Thanks for all your time and energy viewing this
