Question about Maytag MDB9100A Dishwasher
I live in Brazil and have had some components of the control board of my MDB9100AWB dishwasher burned out when I turned the machine on (plugged to a 110 volts stabilized electrical outlet) at my new home. I have called a local technician (did not have another board to replace) and have ordered a new board directly from Maytag in the USA, but never received it.
The question is: Is there any place where I can obtain the MDB9100AWB controller board's electric diagram, so that I can try to fix the board myself?

Well, I fixed it. (It might be too late for the first post - I hope not - but it will hopefully help the next person, SOLUTION: Using a six point star bit, I opened the inside door panel. I carefully removed the inside panel from the door and noticed two rectangular modular connectors that connect on eitherside of the door latch assembly. One of them was loose/disconnected. I reconnected the loose/disconnected modular connector. All is working now. My Model # is MDBTT60AWB. I hope it helps.

These control boards do not have fuses on them. I opened mine up when the front panel touch pad stopped working and the LED indicators were anemic. This is a sign of the ribbon cable connections have oxidized. The ribbon cable connects the touch pad to the control board.
Others have written up nice solutions on similar Maytag diswashers with the touch pad.
The previous expert shows that you can diagnose this by using a 10k resistor and connecting pin 6 and 10 on the ribbon cable connector and it will start the dishwasher (you have to trip the door handle and carefully do this with the power on). This proves that the control board is fine and ribbon cable connections are the problem. Don't forget to quickly trip the door latch once the dishwasher starts.
My solution was to purchase a contact cleaner called Deoxit. You can order from RadioShack.com or get at Frys. Spray Deoxit on both the ribbon cable end (removed) and into the connector on the control board. Deoxit removed the oxide on the connectors. The twin pack Deoxit spray comes with a solution that helps prevent corrosion. I am 1 day into the successful repair of this model Maytag dishwasher.
Previous people have suggested heat and steam get into the control board and oxidize this connector. I notice on the top right where the control board sits, there is a gap to allow steam to get into the door/control board area. I used bathroom caulk to seal both sides of the door to hopefully prevent further corrosion.

Have you tried cleaning with vinegar? Start the washer and let it get to the start of the wash cycle. Open it up and scoop out about a gallon of water from the bottom. Pour in a gallon of vinegar and let it finish the wash. May have to repeat a few times. This should get it. To keep it clean, add a few vitamin C tablets in with your detergent every few washes.
