Hi there, I'm Cole. I think i can help you with this.

so first thing i always do is trace the power back and see where it stops. if it stops at the relay than what is supposed to open that coil? so most common on these spas is pressure switch (wire coming in and coming back out) or high limit sensor/switch or thermostat. sometimes within this testing it could be as simple as one of the buss fuses on the circuit board itself.
