Report Hot Springs Grandee Heater Issue in Portable Hot Tubs & Spas Posted June 8, 2021 I have a Grandee (Serial # G-401033). The heater stopped working and tripped the breaker. I turned the temperature down and reset the breaker. When I turn the temp setting up to 5 it makes an arcing sound and trips the breaker. Assuming I need a new heater? Any thoughts? Can you point me to an owners manual for replacement parts?
