KitchenAid Dishwasher Repair

Appliance:
KitchenAid Dishwasher: Model KDB21

Problem:
Dishwasher not filling with water

Solution:
If it's not allowing water into the machine, it's either the float assembly (part #W10207863) being stuck, (sometimes there is a soap buildup in that little tower, and the float will rise up and stay in position and it won't allow it to fill.) Or the water inlet valve (part #4171000) has failed. That is the solenoid on the left-hand side on your unit.

The other thing you could do is set your multimeter (part #DM10T) to the ohms scale and check the water inlet valve (part #4171000) to see if it has an open solenoid coil. However, this test is not always accurate even if it checks okay electrically; you still might have a physical problem where the valve is not opening. This is not an uncommon KitchenAid dishwasher repair for this type of machine.



Appliance:
2007 Kitchen Aid Dishwasher, Model KUDK03ITBL1

Problem:
Dishwasher is noisy during cycle

Solution:
Sometimes debris, like small pieces of broken glass, can get into the pump area and damage it. When you select the wash cycle the motor starts up and it turns an impeller which moves the water. The impeller pushes the water through the different wash arms, when part of that impeller breaks off it can cause a lot of vibration and clanging. Eventually that debris will damage and break the water seal, and then water starts running into the motor, which can be more damaging to the dishwasher.

So more than likely the problem is debris caught in the motor pump assembly. This is one of the newer style dishwashers. You may have to pull the dishwasher out in order to get at the motor pump assembly. There are a few locking tabs that lock it into the tank and then get it out and work at it that way. Then you just take the motor pump assembly out and you can get in there and look around. You might see the evidence of the debris and remove it. If the motor seals are damaged then it may ruin the motor or it may be dripping water on the floor underneath the dishwasher that you may not be able to see. Many times people don't realize they have a problem with the unit until their wood floor buckles in front and by then it's a much bigger expense than just repairing the dishwasher. If you are going to replace the motor pump assembly, you might want to do it as a complete assembly with the new housing and everything else rather than just get the motor. Normally, it's just a few dollars more to get the whole assembly and it's a lot less messing around in the long term.



Appliance:
Kitchen Aid Dishwasher, Model KUDS24

Problem:
No power to the control panel

Solution:
If the unit is dead, but you have power at the junction box, the next gateways of power are the door switches. There are two switches in the door assembly and the latch assembly that have to be made. Most often if the unit is dead then one of those switches has failed. It comes as a kit with new wiring and new switches. It's possible that the latch, which is plastic, could be broken, not actuating those switches but more than likely the switches themselves have failed. You can turn the power off to the dishwasher and check the switches with a multimeter (part # DM10T).

Other than that, being a circuit board unit, if you have power to the main control board and it's not doing anything, then the board is probably bad.



Appliance:
1991 Kitchen Aid Dishwasher, Model KUDM220T2

Problem:
Not completely draining the water

Solution:
If it's not draining all the water out, you probably have either a restricted drain going out to your sink, or if you have an air gap on your sink check that, you'll probably have a popcorn kernel or something like that stuck in there, and not allowing it to drain. If not, then something internal in the pump is either plugged up, or some of the impellers for the drain have been broken off. The machine is made to drain for a certain designated period of time, and if the pump doesn't have enough force, then it just accumulates water over and over again.

 

The easiest way to get to the pump is to take the whole assembly out. Loosen the hoses going to the pump, you might want to slide a towel underneath it because you're going to get some water on the floor, then the pump assembly will pop up right through the tank, you can pull it up from the top.
