Hi All,
I am new to this forum and I looked a bit to see if anyone else had this issue but did not see it anywhere.
I recently bought a house with a pool and system is about 15 years old. Just the other day, my pool pump went off for the day and I noticed a humming coming from the heater unit (Hayward H250FDP). I have not used the heater since buying my house 6 months ago. The error code on the heater unit is LO with the service light on. I have a DE filter so I did a back wash thinking there was a low flow issue. That did not help. I am curious why the blower motor runs on. I don't believe there is a toggle switch for this unit and am thinking there is an automatic flow switch tied into the unit.
I am stumped and wondering if there is a bad switch. I guess i need to test for continuity on the switch. Am I on the right track?
Thanks in advance.
