i am a first time pool owner, recently my heater had a error message on it and my pool guy told me to turn off the break and turn it back on and that it would clear the issue. that worked, i was able to turn the heater on, but it now has started other things. the heater now reads Lo not sure what that means, but it only reads it when the pool pump is on. the pressure is showing good on the filters. the pump also will now turn on and after a few seconds start to shut off and will turn back on. then some days it will shut off and not come back on. the zodiac panel will read “fault pump not connected” . i have had at least two seperate pool guys come and not be able to determine what the issue is. any thoughts? my husband has checked the pump and it all looks ok but can’t figure it out. sometimes cant even manually turn on on the aqualink panel or the breaker box.
