I own a 2005 Hot Springs Grandee, original owner. The only sevice it has had is the heater was replaced about 5 years ago. It is wired from a 50 amp breaker in the house to panel outside with a 30 amp breaker and 20 amp breaker. The heater runs off the 30 and the pumps and panel off the 20. About a week ago the 20 amp breaker tripped. I reset it and everything seemed fine. Couple days later I went to treat the tub and when used the jets the 20 amp breaker instantly popped. This was repeated a couple times. I called Hot Springs and they sent a guy out. He replaced the recirc pump, heat sensors, and left. Next day I go out to treat tub and turn on jets, treat tub, turn off jets and push the clean button for timed run, 20 amp breaker instantly trips. Attempt to reset breaker but it instantly trips. After hours so no repair person to call. Did note breaker felt spongy. Opened panel all looked good nothing felt hot or odd odor. Board and all pumps are off no reading on multimeter. Cleaned grounds with wire brush and pulled board pins and re sat them. Breaker then was able to be reset. Hot Springs back next day and replaced 20 amp breaker. Tub seemed good for a day but then 20 amp breaker started to trip again randomly and noted temp was high, set at 100 but ready light only illuminated at 103 to 104. Jets could be run off and on without breaker trip. Few hours later temp returned to 100 and ready light lit. Next day 20 amp breaker trips again. Hot Springs back replaces 20 amp breaker for 2nd time saying manufacturer recommended. Runs jets for hour plus temp returns both power and ready lights on all seems good. Hot Springs leaves and shortly later 20 amp breaker trips. Reset jets run all good. 20 min later breaker trips again. Now breaker will not reset. Open panel and disconnect 3 heater relays from board and breaker resets. Recirc pump now running to keep tub from freezing waiting for service again tomorrow. Note 50 amp house breaker and 30 amp panel breaker have never tripped. No flashing indicator lights on panel or board except now the power light is flashing since heater is discon from board. Any help? Thank You. Jered

I’ve got a Watkins (Hotsprings) Grandee GQ and can’t get it to heat. I started with cleaning, then replacing the filters. Then resetting the high limit, then replaced thermistors, and finally a new heater (with no high limit reset). I’ve followed the refill and start up procedures (20 amp first, run the jets to get rid of air locks, then switch the 30 amp), and have had some heat happen. We had an 8 degree jump in 45 minutes, but shortly thereafter, the whole thing shut down. Red power light blinking. The circulation pump seems to be working correctly, and when just the 20 amp is switched, it goes just fine. When the 30 amp is switched, we’ve had different results. If it is the first go around for the day, everything works (heat increases, things circulate properly, etc.) for between 30 and 50 minutes, then back to blinking power light with no circulation nor heat. After that first reset, all following resets provide about ten seconds of proper operation before all shuts down and it returns to the red power light blinking. Anyone have ideas of where to go from here or how to troubleshoot next? I’m definitely a fixer of things, but my technical knowledge and skills are a bit limited, so I can provide more information if needed.
