Open Question

Maytag MDB9100AWB 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?

SOURCE: maytag mdb6000awb dishwasher will not start the washing cycle

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.

SOURCE: MDBH945AWW maytag dishwasher panel lights will not

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 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.

How do i determine if my Maytag dishwasher needs a new control panel or control board

Remove the cover on the inner side of the door and expose the backside of the panel and control board wiring. Look at the wiring and see if you see a burned cable. That may point you to where the problem is. I have seen burned wiring in that location, especially leading to the control panel itself having burned ribbon cable.

My dishwasher the maytag quiet series 300, will not respond to the start button

Find your circuit breaker for your dishwasher and turn it off for 3-5 minutes. Turn it back on, then turn on your dishwasher. If this works, after the complete cycle of your dishwasher, you have to turn it off manually by pressing "on" botton then press it 1 more time to cancel; this will turn off. The defect is, probably the moisture built up in the control board causing it to ground some of the connections. Suggestion for the manufacturer, insulate the control board to prevent absorbing moisture.

Had a power failure from bad weather now the dishwasher is dead? checked the fuse box the breaker is fine, there are no lights on the display panel. what is the reset procedure for this dishwasher?

Try turning the breaker for the dishwasher off for 30 seconds and turn it back on. This should reset the dishwasher control board. If it still doesn't work then most likely the power failure burned up the main control board. The control boards in the newer dishwashers are sensitive to any type of power surges or failures.

Hope this gets it running for ya.

The dishwasher will not turn on

Congratulations - you found the fault !

The options you have are -
Buy areplacement board from a spares centre.
Buy a take- off board from a scrap one on Ebay.
Or - Learn about electronic repair - and identify the burnt component , buy the parts and replace it yourself.

You can take it to an electronic repair shop - if you can find one - or a electronic supply shop - and ask for a new one of "them".

If replacing a burnt component - often there is a cause other than just that component.
Experience tells you what else might be wrong to cause it.

My maytag dishwasher appears dead just after 1 year

You probably have a bad main control or console control unit in there. Turn power off to the machine, be sure that BOTH of your door switches are ok. Unplug your membrane to control panel ribbon cable, then put everything back in place. Leave the door open, then turn power back on to machine. (also, be sure the thermal fuse hasnt tripped while your in the console). After re-appling power, close the door, and wait a few, if the console unit is bad, the machine will go into drain mode (you will here the unit start in drain). If no drain mode, then your control is shorted. You dont have to see any burn marks, etc for one to be bad, in fact, 98% of the boards we replace, dont show any signs of problems. Let me know what you find out.
