Frigidaire Dishwasher Doesn't Drain

About one week ago we noticed a substantial amount of water in the dishwasher once it had completed its run. The float has been checked and appears to be working properly. All seals around the door are fine. The water that is left appears to be dirty or has soap in it. Last night we ran a light wash. Dishes appear to be clean, but again there is alot of water in the bottom of the dishwasher and we do not think that it is draining out. We have followed the hose back to the disposal and cleaned all gunk out in that area. Not much there, but cleaned it anyway. No hoses are kinked or anything. We watched the disposal during the light wash of the dishwasher and waited to hear water rushing through the disposal during a rinse or drain cycle and heard nothing. Incidentally, when looking at the manual for this dishwasher we could not believe how long the cycles of wash and rinse last. Any ideas?

Your model has a separate pump for draining your dishwasher (download the schematics and locate the pump). Disconnect your dishwasher and connect the two drainage pump terminals on 110V directly with an old lamp wire on which you added standard terminals. If the pump is working and terminals show no damages, you must get a new timer board. If the pump is dead, you must replace it after you checked there is 110V supplied on the wires by the timer board in drainage cycle.

If the timer board is too expensive or hard to find, you may follow the drainage pump wire (by the color) up to the timer board and locate the faulty relay connected to that wire. On mine, I unsoldered and replaced the faulty relay in five minutes for a total part cost of 12$ including shipping. You have no mechanical parts on your timer board, so it is easy to fix if damage is limited to a faulty relay. I’m only a handyman, not a technician. It is very simple to do.

Good luck
