Hi-- I have replaced a damaged accumulator assembly in this dishwasher, so when dishes weren’t clean, I took it apart to see if it was operating fine. It was. I have been cleaning the system with a vinegar soak regularly. It seems like the top dishes come out greasier, and less clean than the bottom. (WHich aren’t that clean) Any suggestions? I checked all the water outlets, and the top one seems to be a bit corroded but I cleaned it and it didn’t seem to help. THANKS
I cannot find any info on the given model number, please check it.
A greasy film sounds like the water is not hot enough.
Check that it at least 120 degrees F when entering the unit.
Check that the heating element is working.
Since you have checked your pump/filters there is a possibility that you have a fill problem.
Most units fill to just under the heating coil.
This can be checked by adding a couple quarts of hot water after each fill during a cycle. If it now washes OK then check the fill valve.
Just be careful to not overfill it.
Often if the fill is low you will also hear a growling sound because the pump will cavitate (suck in air).
The most common cause is a dirty screen filter on the input side of the fill calve. Remove the valve from the unit and clean/check the filter.
Do not permanently remove it from the valve as it is there to keep crud out of the valve which could hold it open and cause a flood.
If it still does not fill correctly I would replace the fill valve.
Ok-- It seems to be filling fine but will check the valve to be sure. The coil seems to be a bit corroded so maybe it is the heat issue. Checked the model number again, it seems to be correct, maybe the B is an 8? KUDPO2CRBSO
OK I think I see the problem the original model number shown was KUDPORCRBSO and it should be KUDP02CRBS0.
Here are your parts

See the attachment for the tech sheet.
Remove power from the unit and measure the heating element with a meter.
Also note there is a high limit thermostat inline with the heater. It should be 0 ohms.
