    Pentair ETI 400 gets to 96* and service heater light comes on

    SOLUTION::UPDATE:: Okay, so I figured out the solution for this. Basically, all I needed to do was open the windows in the pump/heater room. Apparently there is a sensor, but i'm not sure which one, that detects pressure in the room. I think most of these heater are outdoors so it isn't an...

    Pentair ETI 400 gets to 96* and service heater light comes on

    good thought. ours exhausts on the roof, since it's located inside of a pump room. maybe i'll take the exhaust apart and try to temp it. thanks for all the help! I'll report back if I have any news. I likely won't get to it until after the weekend.

    Pentair ETI 400 gets to 96* and service heater light comes on

    Long story, but yes. been down that road. they put in a service order at the nearest pentair service provider and i finally get in touch with them, they say "we don't service your area". so I contact the 2nd closesest, same thing. so on and so fourth. so I think i'm on my own for this one!

    Pentair ETI 400 gets to 96* and service heater light comes on

    Thanks for the response. sorry for the lack of info! it is not the hybrid heater, it only uses propane to heat. I do have a VS pump, it's running just fine at 312GPM (it's an 8k gal spa) the whole setup is 2.5 years old, I backwashed the sand filter about a week ago when it reached a 10psi...

    Pentair ETI 400 gets to 96* and service heater light comes on

    Hey there. New to TFP- but glad I found it- tons of useful information so far. I have a pentair heater for a 8,700 gal spa. when I have it heat up, the water temp will get to 96* and then service heater light comes on, and it stops heating. If I shut it off, and turn it back on, the service...
