Question about Frigidaire 24 in. FDB750RCC Stainless Steel Built-in Dishwasher
Dishwasher runs when started and fills with water, but now makes a strange humming sound and appears that the spray arm is not spinning or spraying water. Please advise. Thank you!
1.does motor run? no. replace motor. 2.open 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. 3.you 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.

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 sears.com, 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.

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
