GE Profile Dishwasher Making Knocking Noise Even When Running Empty. IMPORTANT: Read description.

Описание: Important Note: When you spin the bottom sprayer arm it will spin freely, not hitting anything. This might cause you to think that the bottom sprayer arm is not the problem. BUT when water is spraying out of the arm, the lower flexible metal plate is probably hitting your heating element causing the thumping. It was for mine.

A short video for anyone with a GE Profile Dishwasher that is making a periodic knocking sound (1 thumb/sec) even when you know there are no dishes in the way of the sprayer arm. This video will show you a quick way to fix this problem. Good luck!
