I have a 2005 Hot Springs Grandee Spa model 36675.
A new Watkins no fault heater 4kw 240v was installed about 4years ago.
The heater just stopped working. I checked the breaker and tried resetting it but it tripped immediately
. The heater is on the 30 amp gfi breaker by GE. I tried resetting it after waiting a few minutes and it still tripped immediately. I put a tester on the circuit and that would light for an instant as soon as I tried to reset the breaker, but then the breaker would trip. I then disconnected all 3 heater wires from the control panel and the breaker still tripped immediately. All other functions seem fine. The red heater light on the panel also goes on when I raise the temp and goes off when I lower it below the actual water temp so I assume the thermostat is working ok. Any ideas? Could the breaker be bad? They run about $100 on line so I just don't want to guess and replace it. Thanks to anyone who can help.
