- Air control may be closed or may be partly open. Turn the
completely to the left or right.
- There may
also be an obstruction, or possibly the air blower is not working. If
turning the air controls left and right several times doesn’t help, try
removing the top of the air control and checking for debris inside.
(Remove the handle and unscrew the cap.)
- If this does not help, call your spa dealer or customer
