Hayward sum xl140 heat pump heater f5 code what does the code signify

SOURCE: Hayward H300 heater runs but will not heat water

Your internal by-pass could be stuck open or the disc could be worn to the point of letting water pass too fast. Or your thermal control valve could be stuck open. These are both found in your water header going into the heater. Hope this helps, good luck.

The code is "PS" for Pressure Switch and means there is insufficient pressure to operate (low flow) or the switch itself is bad.
