SOURCE: water not going through spray arms

1.does motor run? no. replace motor. door and leave the bottom rack inside dw.spin the spray arm underneath the bottom rack by hand. it should spin freely without binding. if it doesnt spin freely take out the bottom rack and try again. if it does spin freely then your bottom rack is laying on your sprayarm preventing it from rotating. could also not be getting enough water into your dw.

Have same problem except big motor spins independent of stripped? impeller. tried to reassemble but seems mechanical or adhesive agent misssing from one shaft or the other and the motor spins the impeller (now tight) only to have it slip off again and stop pumping water.

SOURCE: dishwasher pump will drain but not force water into spray arms

If the washer is not used regularly the shaft can stick to the seals and prevent the motor from spinning. This happens quite regularly for me if I don't use the washer often. You can just take off the bottom panel - after shutting off power to the dishwasher - and access the motor. you should see some fins and then just try to spin the motor by hand. It usually takes about 90 degrees of rotation before the motor breaks free from the seal. You'll have to fight through the spring-like resistance created by the seal-shaft adhesion. After it breaks free the motor spins freely and you should be all set to go. I haven't found a more permanent fix for this other than running the dishwasher more regularly.

SOURCE: dishwasher - no spray arm action

If it is filling with water properly then it sounds like the chopper screen is clogged so that water isn't getting into the pump. You can remove the top of the pump housing and get to the screen and chopper blade to inspect it. Go to, click on parts and enter your model number and you can view a diagram of the pump parts to help in disassembling it.
If the pump is not clogged then you have a problem with the impeller or motor. If this is the case you can replace the entire sump assembly just about as cheap as replacing individual parts of the pump.
Post back with any questions.
Thanks, Mike

SOURCE: Dishwasher spray arms don't spin & spray water

Could be a a couple different issues.. Not filling with enough water or food chopper broke or food chopper filter screen clogged.

Check water level:
Run the DW and wait for the main wash to start (water will fill. pause then complete fill) The water should be no more than 1/4 inch below the heating element. If not there..replace water inlet valve.

Inspect food chopper:
1. Remove lower spray arm and rear water supply tube to upper spray arm.
2. Remove torx screws that secure the sump cover.
3. Remove primary filter
4. Remove food chopper cover to expose the chopper assembly. Inspect for breakage or blockage.


If you need further assistance, let me know

Why won't my GE dishwasher get my dishes clean?

IF all appears to be working just leacing film on dishes or if not actually cleaning dishes there could be several things it could be... the basics to start with are first make sure the entering water temperature to dishwasher is a t least 120-140 degrees ... run water at sink prior to starting dishwasher.. next remove drain line from under sink and check for any obstruction where it connects. check the area under lower spray arm for trash/food build up and if you can remove spray arm and clean port out of any calcium build up... make sure the water is filling unit properly run a cycle and when you start unit listen when it stops filling open door and make sure it has enough water in it.

The dishwasher fills with water but then hums. Water will drain if cancel button is pushed.

Sounds like something stuck in spray impeller. Remove spray arm and top of motor pump assembly and clean.

My dishwasher has water going in to it and it drains but it's not making it to the arms, my dishes are still bone dry after all cycles even pre rinse.

it appears ur wash motor is not running.try this-start the unit and let it run for 2 min( this is the water fill period) and after 2 mins u should hear motor running and water splashing sound.u can even open the door and look for water falling from the spray arms.but after 2 mins if u hear only a humming sound and no water splash sound then motor is bad and needs to be chgd.drain motor is seperate for draining the water.

My dishwasher is making a humming sound and does not rinse?

A humming sound can be a failing wash motor (that drives the water pump) or it can be as simple as a blockage in the the pump area beneath the lower spray arm, under the filter.
Remove the spray arm and the filter top (screws will need to be removed)
Use a flashlight and inspect all over the sump area for debris that is blocking/jamming the impeller area. Reasemble and test with a short cycle.
If the dishwasher continues to make the same humming, it is time to replace the wash pump.
Good Luck! Post back here if you would like more guidance.

Dishwasher not working

Nothing by the sound of it. The humming may mean the main pump is stuck. If you are able, remove the pump & turn the impellor by hand (or screwdriver) just to make sure its free moving. Put it back into machine & see what you get. Could also mean that the capacitor on the main pump (if it is a capacitor start motor) has failed.
