Spray arm on KitchenAid KDC 17

The spray arm doesn't turn. If I put grease on it it will turn. Seems to have plenty of water pressure. Is it possible for these arms to wear out and if I replace the arm should I replace the shaft it sits on?

Water pressure should spin the arm. If it is not spinning and you have tub full of water-circulation pump could be the problem

Upper spray arm on my Kitchen Aid dishwasher (8573025) doesn't work.

Arm operates(turns) by water pressure. If it does not turn no water is going to the top spray arm. make sure the setting washer is on does not preclude the top spray arm from operating(read manual). If not check arm by spinning by hand to make sure it is free. If arm is free and it still does not turn when DW is running than there is a restriction in the tubing to the upper spray arm or the check ball or solenoid are not operating correctly.

How to repair or fix a Dishwasher if it doesn't wash well

A common cause of poor washing results is improper loading—dishes that block or impede the spray arm(s) or prevent the soap dispenser from opening. On the other hand, if your dishwasher has chronic problems with good washing, the problem may not be your dishwasher. A good first step is vary the amount of dishwasher detergent you're using and try switching brands.

Other possibilities: Your home’s water pressure may be too low, your water may be too hard, or the water temperature may not be hot enough.
In order for your dishwasher to fill to the appropriate level, water pressure should be from 20–120 pounds per square inch. If you suspect that your water pressure may be low, turn off all faucets or other users of water (such as washing machines and sprinklers) and then put a half-gallon jug under the kitchen faucet. Turn on the hot water full-blast. If the jug doesn’t fill within 14 seconds, your water pressure may be too low for proper dishwasher operation. Call your city water utility to discuss your options, or avoid drawing water elsewhere in the house or yard during dishwasher cycles.
The right amount of detergent to use depends on how large your load of dishes is and how hard your water is. Hardness is measured in grains of minerals—the more grains per gallon you have, the more detergent you’ll need. If your water has 12 grains or more of hardness, fill both dishwasher soap cups completely with detergent. If that doesn’t work, consider installing a water softener.
To check water temperature, hold a meat thermometer under the hot water faucet for two minutes; if it doesn’t register a minimum of 140 degrees F., turn up the temperature dial on your hot water heater. (However, if you have a newer dishwasher that heats the water internally, it isn’t necessary to turn up your hot water heater.)
If your dishwasher has worked fine in the past but suddenly your dishes aren’t clean after the dishwasher completes all cycles, listen to the spray arm(s) spinning inside during the wash cycle. If spinning poorly, wait for the machine to cool down, remove the spray arm(s) by unscrewing the hubcap(s), lifting the arm(s) off, and then cleaning out the spray holes in the spray arm(s) with a stiff piece of wire.

Dishes and glasses not clean, seems like spray bars not turning water seems plenty ,no clogged filters


If you are noticing that the dishes are not clean, then there are a few things to check for. Check the soap powder if it's kept in a dry environment. Also try replacing the powder with something like a gel or liquid. Next thing to check for is the water pressure and fill valve. Check if the water is filling in and the spray arms are throwing the water with enough pressure. Try and listen to the sound if you hear a proper spraying action sound.

If it seems as a low water pressure then check the fill valve. Now, check if dishwasher is draining the water or not. While the dishwasher is working check whether the dishwasher is draining and there is not much left out water after the cycle is complete. Try cleaning the spray arm with a soft brush. The water temperature plays a major role in cleaning of dishes. The temp should be between 125 and 150 F for dishwasher to clean the dishes. Hope this helps...

Both spray arms of my DU943PWKQ0 do not turn or spray. The motor is moving and the it drains without problem. During the wash and rinse cycle I can hear the sound of water, however it doesn't clean at...

Try rotating the spray arms by hand. It should rotate freely. If possible clean the arm rotating place by removing them.

Arms rotate by by pump pressure only. finally check the water pump also.

Top rack does not wash dishes.

Possible causes of spray arm inefficiency:
Loading large or tall items in the lower basket which stops the arm revolving.
Upper spray arm split along seam.
Upper spray arm blocked.
Under dosing of powder causing foam and reducing upper spray arm water pressure.
Blocked strainers reducing water to circulating pump, therefore reducing upper spray arm water pressure.
inefficient wash motor impellor (faulty)

My kitchenaid dishwasher needs the rinse aid refilled after approximately 2-3 loads. The top rack of dishes will be dirty, but the spray arm seems to be rotating? Any help?

Possibly needs a good servive. Remove spray arms and make sure every hole is totally clean. As well, take sieve out and pressure wash it as those holes are micro fine and if blocked, wont allow a full compliment of water to flow. see if it runs better after that.

Lower and upper spray arm will not turn

If the spray arm is not binding due to worn out plastic bushings, then it could be a lack of water pressure, because it is water pressure which makes the arm turn.
Give it a gentle tap in a clockwise direction,,does it spin easily?
If it does,,then it will be lack of water pressure that will be the cause.
Possible pump wear or failure.
