To the upper rack.
Pull the Upper Rack Out. Look at the Center of the upper wash arm. There is a Flat tube that runs to the back of the rack. It may have slipped out of the fitting that connects it to the Feed Manifold on the back of the tub. If that is not the problem, feel the bottom of the feed tube. I picked up a KDS 20 about 4 years ago and the whole bottom of the feed tube was rotted through almost the whole length. |

How did you figure this out - did you put a pressure gage on the faucet? |

KitchenAid dishwashers fill with water solely with a timed fill design. So, if there is low water pressure, or if there is sediment in the valve or solenoid that is restricting the flow of water, then each fill will be insufficient. To verify this, let the machine go through a typical fill period and wait for it to start circulating waer after the fill. Stop the machine by lifting the handle, open door and take note of where the wash arm under the top rack is. Now, add another 3 quarts of hot water. close door, latch door, and push in cycle button. Let it run for about 30 seconds and then open door and see if the wash arm under the top rack has moved in rotation from the original location from when you opened the door. |

Chris is likely correct, bad inlet valve. You can check by allowing DW to fill and when it is washing open and close the door several times [ restarting it each time ] and note weather the top arm is in a different position each time you open the door, if not pour an extra gallon of water in the bottom of the DW and try this test again, if it now turns you can conclude you are not getting enough water. You can remove the inlet valve and look at the inlet and see if the inlet strainer screen is completely packed solid with sediment, if it is try cleaning it and reinstall. If there is only a little bit of stuff on the screen don't waste your time cleaning it, just buy a NEW valve assembly and install. |

If you decide to get a new water valve, get one from Ebay. I recently installed my KDS-18 and found a very slow leak at the water valve. I ordered the 4171000 single coil valve to replace my original double coil one.

Generally do not clog especially if you have have a tank style water heater as heavy particles stay in the bottom of the tank. We do see cases where the plastic dip tube in water heaters disintegrates and the little plastic particles will clog the inlet screen, however by the time this happens every shower head, faucet air=rater and washers hot inlet screen have already clogged and the customer is well aware of the problem.
If you do have to clean the domed style rounded screen it is best not to try to remove it to do so. If you remove it and bend it ever so slightly and it does not seat perfectly when reinstalled a small particle can get past the screen and make the valve stick open and you will have an uncontrolled FLOOD of HOT WATER on your hands.
When an Inlet Valve is over 20 years old and is showing any sign of problems and when you can still get a good quality replacement I would do so.
The 4171000 valve does not come with a new hose and you normally donot need one to use it on a KDS-21 DW, Good Luck. John |
