frwlf2 Posted October 23, 2021 Report Share Posted October 23, 2021 (edited) Hottub will not power up. I verified power going to the hotub. Display is blank, appears to be getting no power. Is it possible it a fuse? I didnt see any. No previous issues with unit. Not sure how to troubleshoot Edited October 23, 2021 by frwlf2 Spelling Quote Link to comment Share on other sites More sharing options...

RDspaguy Posted October 24, 2021 Report Share Posted October 24, 2021 That's the one. That spa has 2 breakers, one for the heater and one for everything else. Did you check both circuits? Do any LEDs light up on the board or topside? Quote Link to comment Share on other sites More sharing options...

cranbiz Posted October 25, 2021 Report Share Posted October 25, 2021 Follow the AC power line back to the Spa Panel/Spa Disconnect. Inside that panel should be both circuit breakers. 1 Quote Link to comment Share on other sites More sharing options...
ratchett Posted October 25, 2021 Report Share Posted October 25, 2021 15 hours ago, frwlf2 said: Im not sure where the breakers are on the hottub for those 2 circuits Many hottubs only use one 50amp or 60 amp breaker to power the entire tub. Watkins 220v tubs are wired to require two breakers - a 20 amp and a 30 amp. Very common wiring mistake people make is they assume Hotspring/Caldera can be wired to a single breaker the same way as other hottubs. 1 Quote Link to comment Share on other sites More sharing options...

RDspaguy Posted October 27, 2021 Report Share Posted October 27, 2021 I can see from your wiring that you have 2 breakers, or at least the wiring for 2. Find the disconnect and check the breakers. If it really is one breaker, check the wiring, since they would have had to double-lug the breaker or splice with wire nuts. Quote Link to comment Share on other sites More sharing options...
