Guys - new pool install with Hayward H500 natural gas heater. Bypass installed for start up, flow meter for correct flow rates per manual. Large spa - 12x12 approximately. Keep getting LO and lockout when heater gets water up to about 75-80 degrees. Warrant company comes out and checks and replaces almost all sensors... Test runs the unit again, same thing. Now they are saying the unit’s heat exchanger is bad due to a 50 rise in temperature and a high limit lockout. The heat exchanger is not moving the heat away and over temping. Hayward is assuming heat exchanger damage now due to the temperature rise of just over 50 degrees... They are now telling us that is due to poor water chemistry. The pool was started around Thanksgiving and the heater was bypassed until just around Christmas when it was used to heat the spa and at about 90 we had a LO for high temperature right off the bat... Hayward now refuses to warranty the unit sighting poor chemistry. The water tested - see attached - not too far out of “normal”. No one has taken the heat exchanger out. They are assuming this due to the rise in temperature. See photo of coils attached too. Any ideas??
Thanks
Jeff
