    When it finally stops and the service heater light is lit, leave it turned on and remove the covers and then the dome top, flip it over and see if there is an LED lit other than the service one.

    Each LED has an abbreviation next to it to tell you what it relates to.

    Re: max e therm cycling

    If that's the case, you probably have a broken bypass then. System is them heating up and cooling off. Where you took out the regulator, up top of that inside is the bypass. Feels like a round disk. If you don't feel that, then that's your problem.

    Re: max e therm cycling

    I just experienced the same problem as the OP had. 4 year old heater cycling with the HLS led lit during the off cycle. Pulled the thermal regulator and found corroded and would not open when put in boiling water test. No one had the part locally, so ordered online, replaced and the heater is working perfectly!

    I am going to order a couple more as I believe my salt pool contributes to premature failure. I guess I should expect 3-4 years out of the regulator.

    A question to the experts then... Would it be a good idea to bypass my heater when I know I'm not going to be using the heater for a few weeks period of time? Could I prolong the life of all the parts coming into contact with the salt water by doing this? I'm only getting about 18 months life of the external safety pressure relief valve due to the corrosion.

    Thank you so much to the experts here for assisting me in solving my heater problem so quickly & efficiently. You guys ROCK !!!

    Brian
