Washer arm not rotating

Common Problem

1. Confirm the wash water is hot
   1. Try heated wash(sani wash) if available
   2. Run hot water in sink to warm up before starting
   3. At least 120 degree Fahrenheit water temperature
      
2. Open door check wash arm position start washer for a minute
   1. Confirm wash arm has rotated
   2. Check for plugged spray tips at either end of wash arm.
   3. Use small tweezers to remove
   4. Check for rack and dishes interfering with arm rotation
3. Place cup in upper rack with opening up cycle washer.
   1. Confirm that cup quickly fills with water
   2. Not washing check water level in tub mim 1 1/2 inch
4. Discontinue use of rinse/dry liquid additive.
   1. Confirm rinse/dry additive not leaking from dispenser into tub
   2. Washer detergent contains sparkle additive and too much sparkle/rinses/dry additive will coat dishes
   3. Try alternative wash detergent that contains minimal rinse/dry additive and use without liquid rinse/dry additive.
5. It will take several wash cycles after the elimination of rinse/dry to purge the oily film from dishes and machine..
6. If success "joy" is achieved with no additives then cautiously add back wash detergent with additives. Additives are important to facilitate drying and protecting the glassware china from leaching. The leaching process permanently etches the surface of glassware leaving a cloudy appearance.

Check your upper wash arm.... check the holes, especially the ones at the end of the arm. Are they possibly clogged with debris or hard water? This is the usual cause of dishes on the top rack not getting clean. The holes at the end of the wash arm are angled to eject the water at an angle to use the reaction to push the wash arm around. If those holes are clogged, then the arm won't rotate, and only those few dishes or glasses right under the arm will get clean, and the remaining 80% of the dishes on the upper rack won't get clean!

Check the nozzles of the arm themselves. if you found lots of gookl there maybe some inside the arms blocking the spray holes which cause it to spin

Check that the arms spin freely when spun by hand, then check the outlet jets at the trailing end of the arms are not blocked with food particles and other solid matter. This often happens and the arm is unable to turn because the water jet that is supposed to drive the arm does not have the force to rotate it with the result is that the upper dishes do not get enough water and chemicals. .

Your sprayer arms may be clogged.
The upper arm attaches to a tube in the back of the dishwasher. If the support clamps come loose, the upper spray tube will not be flush with the tube and can't carry water to the sprayer arms. Also the sprayer arms can become clogged with paper remnants, bone fragments, or pieces of peeling. You'll need to remove the sprayer arm and flush it at your sink. If there is a jet that is clogged, tweezers will help remove the residue.
Finally, the bottom of the door INSIDE the washer often get covered with gunk. Be sure and gently wash the bottom of the door INSIDE. You can open the door, spray some window cleaner on the bottom and then gently brush away the 'gunk.' Rinse with hot water from a pitcher or your sink sprayer and this can eliminate some of the residue that is showing on your dishes.

Hi

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... Please post back if you need more informatiion.

replace the washer water from bottom of the unit up to the top arm water feed assy,they get worn and water leaks by the hub arm that pressurizes the upper wash arm,this is also true on the center arm if the washer has one

Replace the pump, if you go through the trouble of repairing the pump and all the disassembly and then more problems will probably ensue. As far as location it is usually located under the washer. Accessed through the front service panel. Make sure you follow all safety procedures #1 being unplug the washer or turn off breaker prior to proceeding.

Sounds like the washer arm is not rotating around during the wash cycle.. Can you reach in and manually rotate the arm to make sure it is free to spin? Also, it may be washing but the drain filter has so much sediment in it from previous cycles that it is just redistributing that stuff on you dishes.. check the drain filter too... lastly, is the detergent dispenser opening after a wash cycle? If it is empty ( meaning it has been used) the other things mentioned above are probably the issue.. Hope that helps...

Do you know if the washing arms are turning. Normally after the machine fills up the main pump begins and the washer sounds like it is washing dishes. If you carefully open the washer at this point (just a little) it will be eveident that water has been sprayed around inside as it will be dripping everywhere. If not you pump hasn't activated. This does not mean you pump is broken however it could be the pressure level switch sticking and not completing the circuit that starts the pump.
