I believe the code is SNS which is sensor failure. It thinks your pool water is either above 110 degrees F or below 36 degrees F. Post the exact model/serial and will assist you further. The sensor is not expensive and somewhat easy to change if you are mechanically inclined. If not, I would strongly advise you to call your local mechanical contractor to service this boiler and it does not have to be a pool company, it can be your furnace contractor. Or let me know where you are located and I can recommend someone from that area.
so if the water is in fact below 36 degrees as is the case here it has been 20 degrees for the past 3 days when water warms back up the heater should be fine right?so if the water is in fact below 36 degrees as is the case here it has been 20 degrees for the past 3 days when water warms back up the heater should be fine right?
