Frigidaire Dishwasher won't turn on

SOURCE: Maytag MDB9100AWW Dishwasher

We have this same model. Right under the 5 yr warranty mark, the control panel started going "funny". Some of the buttons stopped working, then more. We could finally get it working only in one mode. I was certain it was the control board, which I replaced under warranty just in time.

This lasted another year, until moisture began appearing under the number window and the left side button set stopped working. Now the right side is gone, except for the delay-start button.

I believe moisture is getting into the control board and frying it, either slowly or quickly. If you are seeing similar problems where buttons seem to stop working, it is PROBABLY the control board. It is a relatively easy home repair if you know your way around a screw driver.

SOURCE: dishwasher not draining completely

If you take the toe panels off and look at the motor you will see the discharge anti-siphon tube there with the drain hose attached. That tube is the discharge major restriction point. Be careful not to destroy the anti-siphon valve, by pulling the bale, remove it, a flapper valve. If you can't see through the tube you have found the problem. Punch a screwdriver into it to dislodge the crap and clean it up. Put the anti-siphon valve back in as found and check it out. Be careful, when you remove the tube , water will come out of the pump assembly. If you remove the hose be sure to watch for water there also.

on a dishwasher an ohmmeter is almost useless. the best way to check is to look for voltage. at the door switch check for voltage to ground on both sides. if you have 120 on both sides of the switch then follow the wire over to the control board. if you have 120 going into the control board and nothing coming out of the control then you nood to start looking for a broken neutral. however the likelyhood that its the control panel may be a better idea especially if you are hitting buttons and nothing happens. try reseating any ribbon cables

hi there,

as u said that u have already replaced the timer u may also try the following:

Power from the house Is there power getting to the dishwasher? This can be difficult to test, because dishwashers are usually wired directly to an electrical circuit, rather than plugged into the wall. But at least check for a blown fuse or a tripped circuit breaker.

Door switch The door switch is important because, if it's defective, the dishwasher won't work at all. To reach it, you need to remove the control panel cover, or sometimes the interior liner of the door. If it's defective, you need to completely replace it.

Wiring Often the main wiring connection from the house, at the dishwasher, burns and breaks the connection. If that's the problem, the wires must be repaired/replaced as necessary. If that's not the problem, check the wiring to the door switch, the wiring between the door and the lower part of the dishwasher, and the wiring to the timer. Repair any broken, burned, brittle, or defective wiring, using the proper appliance-grade wire and connectors.
