We have previously heated our spa one time with no problems. This is a brand new build all new equipment. Went to heat the spa tonight and the heater wasn't on. Service light was on and LO error message was displayed on the screen. I tried again while at the heater, it ignited and ran for a few seconds then cut off. Service light came on and LO was displayed again. I did a backwash of the pool filter and tried again. Same thing. Anyone know what I should do next? So frustrating!!
Also, is it normal for the filter pressure to raise when just the spa is running? While in normal pool mode with filter on high speed it's around 20psi, but when I put it in spa mode, it raises to above 30.
