My dishwasher is not cleaning like it used to. Dishes are greasy and food particles in the bottom when cycle is finished and my dispenser for soap does not open.
How can I remove my sprayer arms so I can clean them out. I had a paper napkin in my dishwaser and it dried on arms and ever since then it's not working good. I think it's clogged up.

Unscrew the round piece that hold the spray arm on.

If the detergent door is not opening there may be a problem with the wax motor.

You will have to test it with an ohm meter.
