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.

Hayward heatpro running but not heating. The "run" light is yellow but it should be green


i have found nothing in any of my heater manuals to account for the color of the light. in every instance, the light is either lit or not. the color does not change.
as for the not heating, if the outside temperature is less than 60 degrees, your heat pump will not work well. as heat pumps do not heat water very efficiently, there may not be a noticeable difference in water temp. the best way is to measure the temperature going into the pump (outside ambient temperature) and the temperature of the air exiting the top of the heater.
if the outside temp is 70 and the air out of the heater is 65, there is a 5 degree temperature applied to the pool water. this can be diminished due to transfer of heat to system

OP error code. What is wrong with my Hayward pool


OP is the error code for a faulty Temperature Sensor. Try replacing the Temperature Sensor. I have seen many of these units have the wires chewed up by mice, etc., so you may want to check the wiring for any damage.

My hayward pool heater is displaying P5 and the fan is not moving. what does this mean?


You heat pump is actually displaying "PS" for Pressure Switch. Either there is not enough water flow or the switch could be bad. If you have a sand filter, put the filter head in the "bypass" mode and try again. If the heater works, filter problem. If not, heater problem.
