Having problems with your KitchenAid Dishwashers ?

I have a KUD1220T0 Model. The top level doesn't clean or the arm don't rotate.


Answers :

Hi.

The model number did not match, I believe we are talking about the following model. Please click to get parts and diagrams: KUDI220T0 .


If the bottom arm is spraying, then the problem can be:

Pressure from impeller pump.
Obstruction in the way of spray arm rotation.
Clogged spray arm orifices.
Leak in lines to upper spray arm.

In order to fix the problem:

Obstruction in the way of spray arm rotation.
\015\012Rotate the spray arm by hand, ensure that there is no obstruction in its path.
\015\012
\015\012\015\012Clogged spray arm orifices.
\015\012Check and eventually clean the arm orifices using citric acid solution.

Pressure from impeller pump.
Remove hoses from pump and remove eventual blockage. Ensure that the machine is filling at correct water level. If there is underfilling, which can result in low pressure, more parts must be tested. If there is underfilling, check inlet hose, pressure switch and overfill device.
In some case the pump needs complete disassembly or relacement. Pump problems are often accompained by a noisy pump.

\015\012Leak in duct to upper spray arm.
This is one of the most common reasons for the problem. Check the water ducts going to the upper arm and ensure that there is no leak. Eventually replace parts if they are not fitting together or if they are broken. Please refer to the diagram below. Click on the picture to enlarge:

Do not forget to disconnect power before performing any maintainenance.

I have a Whirlpool Gold Quiet Partner III that is 8 years old and recently stopped cleaning top rack dishes. I remember finding a mylar like piece in the bottom of the tub and threw it away thinking it came off of something we washed (I know, bad thinking.) The mylar piece measured roughly 3-4inx2in and was folded in half. Anyways....the upper arm does not spin and the detergent doesnt get fully dispensed so dishes dont get fully cleaned. I am guessing not enough water pressure to upper arm. Wou

Whirlpool Gold Dishwasher - GU2700XTSB The top rack of the dishwasher is not cleaning. The bottom rack dishes clean fine. There are no clogs in either the bottom or top spinner arms, the plastic tube feeding water from the bottom pump to the top rack spinner arm is clean, the spinner arms all rotate freely and do not bind. Water pressure is correct and water temperature is correct. There are no lime or hardwater deposits or clogs. What could be the issue?

The top level is not getting clean. We think the passage to the top water jet is clogged. There are two holes in the back that the washing arm fits into, depending on what level the top rack is set at, and one of them is stuck open. We have not been happy with this dishwasher from the start and are trying to decide if we should get it fixed or just buy a new one.

My dishwasher's top rotating sprayer keeps coming loose. The screw and plastic bearing fall out and I think that it has stripped out the end where it seats into the top of the washer. Any ideas on how to anchor this in? Adhesive? A larger screw? The plastic bearing is Part No. 568 and the screw is Part No. 569. If I replace the conduit arm (Part No. 585), will that give it a new, clean spot to screw in too? How difficult is it to replace this arm?

I haave dishwasher model 665.743893. The top dishes do not come clean and I suspect that the top arm is not rotating because it is in the exact same position each time I open the door and at the end of the cycle. I took it off to remove possible debris but found none, though difficult to look inside. Do you have any suggestions?


If you can use a high-pressure washer or air hose to blow it out, that would be helpful. Otherwise soak in hot dishwater. Do check the hose to the arm and make sure that is not blocked as well. ... Kenmore Dishwashers
