Maytag Dishwasher Repair
Maytag Quiet Series 400 Dishwasher
Not Drying Dishes - works perfectly otherwise
First of all, make sure that the heating and drying selection is chosen on your dishwasher. If it is, in this particular situation, there are three or four components that can cause this failure.
One is that the heater itself could fail; the current is also wired through the door switch, and then another small thermostat mounted underneath the unit which senses the temperature of the tub. The control board is what completes the circuit for the heated drying to work.
You will have to troubleshoot this Maytag dishwasher repair and find out where you're losing voltage and on what component.

Making a groaning or moaning noise
It could be when the unit is filling, depending on the water pressure in your home; you'll get a high pitched whine that is actually water coming into the machine. If that's the case then it could be that the water inlet valve (part #6-920534) is starting to get a little restricted. Or, it could be just your water pressure versus the valve, and there's not much you can do about it; if it's working properly just leave it alone.
If it's in the motor assembly (part #6-919922), the first thing to do is, after turning off the power to the unit, you can remove the lower panel. Normally there are a few screws that retain the lower panel, and look at the motor itself to see if you see any signs of a leak or any water residue. If that's the case, then what's happened is the motor seal has failed, and you're getting a small amount of water dripping into the motor bearings. Over a period of time it will cause those to wear out you're better to just replace the motor pump assembly. If that's not the case, or you don't see any signs of water leakage, you could still have some bad bearings in the motor, and again the only way to really determine that is to run it, you have the lower panel (part #6-917688) removed where you can hear in the underside of the machine, and try to determine where it's coming from.
