The maintenance guys had been working on the dishwasher unit and had somethings taken apart. I checked power and I was missing a leg, so I found a bad fuse at this disconnect. The customer had a new fuse so I installed the new fuse and everything was working but the drive motor. I made the corrections on the wiring on the new contactor and overload that were installed before I showed up. The unit is running fine at this time and the maintenance will put the other things back together that they had apart before I came.
