SOURCE: Hayward pool heater - p5 code

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

My Hayword Heat Pro pool heater has been running ok for many hours, then, without warning or interference by me, the intake hose on the filter blows off. I have redirected water flow to avoid heater and...


I am guessing the pressure setting is not what is should be. Either your pool is larger than the heater can handle or the settings need to be readjusted. What I guess is happening is the heater is taking in more than it can handle. This causes pressure build up and will pop out the filter.

What does p5 on display mean


Thank you for posting your question here on Fixya.com.


I believe your code is PS, not P5, and it means the pressure switch is open.


That unit will not fire until you resolve the pressure switch issue; either the flow is reduced too low and the pump/filter system needs to be thoroughly cleaned or the switch or control board has failed and need to be repaired.


Start with a cleaning of all baskets and filter to see if the light clears and the heater works; if not look at replacing the pressure switch. It is not uncommon for the switches to fail but check it with a meter set to ohms if you can. Power off the heater first and pull one of the wire leads off. Put the probes on the terminals with the pump running and see if you have a circuit. If not, replace it. If the switch tests fine the problem is in the control board and it will need to be replaced.

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.
