If your hot tub won’t heat the water properly, it could be the heater element or low flow from your pump. Most heating failure result from corrosion caused by low PH in water supply. Any PH below 7.0 damages the heating element and trips the GFCI breaker.
Why is my hot tub stuck at 85 degrees?
Those pumps generate a lot of heat due to friction, and that’s why your hot tub hasn’t cooled down to the air temperature. If a circulation pump has failed, the heater will stop working and there’s no friction being generated; the water will continue to cool until it reaches air temperature.
Why is my hot tub not heating up all the way?
Low flow in your spa or hot tub is most commonly associated with a dirty spa filter. If your spa heater won’t heat, remove and clean the filter(s) to rule out a pressure or flow rate problem. Low water level, a clogged pump impeller, closed valves, clogged pipes, or blocked spa drain covers can also cause flow issues.
