Frigidaire dishwasher FDB710. The spray arms seem to stick.

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.

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.

I found on my first dishwasher the arm holes were plugged. I had to clean out each and every hole with a small wire. They would not even turn until I cleaned them God luck.

When a dishwasher has been checked for obstructions in the sump area and the spray arms can spin easily (by hand) plus the spray arm holes are not blocked, you end up with either a broken impeller or a failing wash pump motor.

If you would like more details of have more questions, please post comment back here, OK?

Good Luck!
