My washer /dryer combo drum will not spin, and when the initial wash cycle starts the water will not shut off and starts to fill the drum. About a month ago I noticed my clothes were not fully drying. As time went on the motor seemed to be cycling several times before it would spin out, and hardly at all in dryer mode. Eventually the machine threw a "PF" fault code. I powered it down, unplugged it, powered it back up and it worked fine for about 30 minutes, and then it completely lost power. I found that the main PCB was blown. I replaced it. Now the machine once again powers up, but the motor and overfilling issues remain. I tried performing the "QC" tests called out in the factory service manual, but can't even get it to perform the 1st (tumble clockwise) test. What could possibly be the cause?

ANSWER Hello Mark. Check the drain pumps and make sure they are not clogged, and the drain pipe is draining properly. If not, it will cause the problems your having. Hope this helps.
