Frigidaire Dishwasher Model FDB989GFC2

I called in a repair person. The repairman indicated that the control board is not getting power. The quote to fix this problem is the cost of a new machine. So, I paid for the diagnosis and asked my brother-in-law (who is an EE) to check the control board for me. He tested the various connections and it seems to indicate the board is getting power. He thinks there is a short somewhere. Can anyone give us an idea what to test?

I flipped the float several times, but nothing happened. The water inlet valve is getting 120. The door switch is also getting 120. We tried pressing the hi-temp wash and start/cancel button but the machine won't go into test mode. What else can we test?
As to the tech, the first thing the tech did was to open the control panel and tested the board. I didn't see which part of the board was tested. But, the tech said there is power going to the display board but no power on the control board. Therefore, the control board needs to be replaced. The float was not tested at all. In fact, only the control panel was looked at and nothing else.

we pulled the wires from the bad switch and connected them with a test lead and tried again. it worked!!!!!!!!!!!!
looks like we need a new door switch.
Thanks Ron and denrayr for all your help.

I have 2 additional questions:
1. The plastic cover for one of the wires that plugs into the door switch is charred and cracked. I used some electrical tape and wrapped it before plugging the wire into the new switch. Will this cause a problem? Should I have replace the wire as well?
2. The heating element on the bottom of the tub has some rust (from the standing water when I had the problem), will this cause any problem? How should the rust be removed?
