I've never used my heater to heat the pool, but tried last weekend just to bump it a few degrees for a party. No luck.
I get the "pressure switch" error when I try to heat the pool. The heater (Laars LX400) works fine to heat the spa.....same pump, just routed to spa when in "spa mode".
Am I not getting enough flow while in pool mode....or too much flow? I tried backwashing, since the pressure was a little high on the filter, but that didn't change a thing. I know when I run in spa mode, the pressure in my system is higher (less piping), always has been, but only a tad bit higher.
