Thank you for the reply. I just want to make sure I'm on the right path! When I power up the dishwasher all the displays look ok, it says there is left in the cycle, so I'm assuming the motor packed it in during a cycle thats why the display shows what it does.

Does this sound right to you pro's? I'm a diesel tech not a dishwasher tech! Yes ,but make sure to tested the main pba cn1 white to cn14 violet when operating, v also check the power relay just to be safe if they check your correct. I pulled off the distributor motor to check the microswitch and found the plastic cam that attatches to the motor was missing!! I ordered the motor, cam and the seal from a local parts supplier, installed them and so far so good it has worked fine.

I don't know who was in there before and removed the cam and seal, but I bought this at an auction as is! Thanks for your help, Jaymie.
