Hot Tub Doesn T Fully Turn On Hot Tub

Chosen Solution

when hot tub is trying to turn on, it goes into Purr mode for few seconds then turns off and starts Purr mode again. end up in the endless loop of purr->off->purr….

Hi @vbr , What is the make and model number of the hot tub? Does the pump motor actually turn on (water movement) or does it just make a humming sound? If only a humming sound it may be a faulty pump motor start capacitor (if it has one) or a faulty start winding on the pump motor.
