First post. I have a Pentair Mastertemp 400 heater. Last week we turned on the heater to heat the spa and the heater did not ignite. I went over to the equipment and see no power at the control panel on the unit. I did see a plastic bucket had blown over and was laying on the exhaust vent. I can see a small amount of the bucket melted due to the exhaust heat, probably from the last time we used the spa. Is there some kind of thermal overload breaker or any circuit breaker within the unit itself. I have checked the sub panel and there are no beakers thrown there. What else would cause no power at the unit itself?
Any ehl would be appreciated.
