If your hot tub control pad and spa equipment are not operating, that means you have no electrical power to the spa. Turn on or reset the GFCI circuit breaker to supply the spa with power again. If this does not solve the problem, have a qualified Electrician check the electrical service for issues. Another reason your control pad and equipment won’t work is if the fuse (20 or 30A depending on the system) has blown. Contact your authorized Bullfrog Spas Dealer for repair/replacement.
