KUDS-22

[kate]

We are restoring a KUDS-22 and wondering if someone has a copy of the service manual that could be shared.

Does anyone know the significance of the final digit in the model number, from zero to four?

Thank you. I have thoroughly enjoyed all of the writings here about the 22.

Thank you!

Thanks for your response, Gary. I believe the Parts List from Kitchenaid is what was needed. As found, a failure to drain was traced to a grommet and another small piece lodged in the line. Their removal cleared up the drain problem. Perhaps we can now discover where they came from...

This past January I installed an In-Sink-Erator (ISE) Classic Supreme dishwasher (pictured below), which is the same as a series 22 KitchenAid, and I am very pleased with it.  I haven't found any issues with the single rinse after the main wash, which is a characteristic of the 22 series.

 

If your machine is a Monterey model, I'm particularly envious.

Loose pieces in KUDS22

Is anyone familiar with the composition of the check valve assembly? That was where a loose piece was blocking the drain line... which was removed. We don't know whether it originated there or moved down the line.

Any suggestions?

Check Valve, not drain valve

Kate, your machine does not have a drain valve per se, but rather a check valve. The water is drained from the tank of the dishwasher by reversing the motor which drains it. The check valve comes apart and you should see a black rubber flapper inside of it. If it is missing, it may have been the part you said you found clogging it up. You can unscrew it to take it apart.
If there is no flapper left, you will have to replace the valve or IIRC, one of the members here knows what you can use in its place from another brand of machine.

Hope this helps and I am sure other members will chime in too.

Check valve

Thank you, Steve.

Is that the sort of thing which might be found at Appliance Parts Co. here? I look forward to hearing of other replacement options, in case of need.

I believe the other loose piece was described as a very small cup-shaped piece found in the vicinity of the lower pump housing.

This is a great help!

Kate, those small parts you found in the line don't sound like check valve components.  The valve itself is nothing more than the rubber flapper Steve described above, located in the middle of a large plastic housing.  There are a couple of ways to determine whether or not the valve is defective:  1) A visual check.  If you look into one end of the housing and can see through the valve, the flapper is stuck open, which means it's bad.  2) If you find the flapper is closed, blow through the valve housing in the direction of the flow of draining water.  If the flapper stays open, the valve is bad.  If it returns to the closed position, the valve is good.

 

The GE part number for a new check valve (the rubber flapper component only) is WD1X1486.  Appliance parts retailers should be able to get this item for you.

Thank you very much for the further info, Ralph.

CHECK VALVES ON KD 21-22 KA DWs

The easiest way to check this part is to simply try to blow through it in each direction, one way it should be easy the other impossible. Anyone with one of these machines that is using it as a daily driver should consider replacing this part if the DW has been used all its life. The other parts that should almost always be replaced on these is the main pump seal and inlet valve, also look at the rubber hose on the top rack for any serious signs of deterioration. Other than these key parts just fix or redo what looks bad and you stand a good chance of getting 20-30 or possibly more years of use out of one these machines. John.

Based on the advice found in this forum, I had previously replaced the check valve flapper (using the GE P/N mentioned) as well as the inlet valve assembly on my KUDS-22. Replacing both parts contributed to significantly better washing performance.

Thank you, John and Bob. Will do.
