I have anH150FD pool heater. I keep getting an HS error code. I'm thinking the thermistor or the "high limit switch" may be faulty. I don't believe there is a water flow problem.
Should I replace those two items?
John, The HS error code is usually caused by 1 of 2 things: A) Inlet water temperature sensor is reporting a temperature in excess of 104°F. Normal operation resumes 2 minutes after inlet water temperature sensor reports temperatures of 104°F or less. This error functions in both normal and remote thermostat modes. or B) Inlet water temperature sensor is reporting a temperature change at a rate faster than 6°F in 60 seconds, indicating a potentially damaging low water flow conditon. Normal operation resumes when temperatures stabilize. If this condition is detected 3 times, the heater will lock-out until the electrical power is cycled off and back on.
