(Chrome push button model only) This is not a common problem but should it happen the chances are the small clear tube which connects to the back of the button has disconnected itself. To fix this problem simply pull the unit out and locate a clear pipe which looks like it's not attached to anything. Next, reattach the pipe to the back of the chrome button you push to operate the whirlpool. We recommend you use a cable tie to secure the pipe into position to prevent this happening again. The reason this happens is the pump operates on pressure so when the button is pressed it forces air into the pump to start the motor. If the pipe detaches itself it will either not start the pump or keep it running continuously.
