power is going to the spa and check the water level. If this does not solve 
the problem, contact your authorized Jacuzzi dealer or qualified service

Check the following:

seconds at a time. Turn power off and let the air out of spa plumbing 
system by removing the lter cartridge (Sec. 12.1, page 33). Make

and restarting the jets pump 1.
