Our Hayward Heat Pump went off last night and was flashing an LS error code. According to my book that means low/no flow. I have my Polaris 280 on a timer to come on from 3am-7am every morning. Last night was the only night we had a problem. The low was in the lower 60's so it was not temp related. The "clean" pressure of my Hayward filter rests at about 18psi, has since we installed it. It WAS up to about 23 psi this morning. Is that enough of a pressure climb to make the heater not get enough flow when the Polaris was on also? The Polaris also has a dedictated line with a booster pump. I did backwash it and the polaris and heater worked again together and all is still fine. I had previously backwashed Saturday. My water is crystal clear and we are dealing with some residual pollen, but the water from backwashing was not particularly dirty, not as it was Saturday. Our furninture is not all green as it was in the past weeks either from the pollen.
PB thinks I shoud add some filter cleaner to it. But, the filter was only installed last Sept and we used it until late Oct, then for about the past 2.5-3 weeks now. I wouldn't think it needed cleaning yet. I also backwash it once a week regardless of the pressure showing it needs it so I know it is not that dirty. We have never had an algae outbreak either.
