dishwasher will not cycle threw and spray the water
dishwasher will fill up with water but does not spin the paddles
The pump is not working. Your dishwasher pump ejects the water. The pump is usually mounted directly to the motor, then attached to the bottom of the dishwasher. You can reach the pump from inside the dishwasher, but first you need to remove the lower rack, the spray arm, and the spray arm support.
Look for an impeller--a round plastic fan blade-type of device that spins around. This is the wash impeller, which forces the water through the spray arm. Beneath the wash impeller is the drain impeller, which is similar in size and shape to the wash impeller. The drain impeller pushes the water toward the drain port. These components make up the pump. If any of the pump components are defective, you need to replace them.
After reading these it seems like my issue could be many things. How do I diagnose to narrow it down. It runs a cycle but not spraying water. A service tech told me it was the control board and I spent $150 on it but that did not solve the problem. I do not want to spend more money on parts that might not be needed. Any ideas. Thanks.
