I bought my house 2.5 years ago and originally my sta-rite heater had the "service heater" light on. I never did anything about it. Now 6 months ago it would randomly turn on and off while the pump was running. I still did nothing about it. Now its not working at all and all of the lights on the controls are lit. The lights on both the front side and the diagnostic lights on the bottom side of the membrane. I am curious if my issue is mainly the membrane pad. I realized after it broke down that it has been missing a plastic covering over the temperature gauge. I assume that this has allowed it to get water inside. Can anyone help me out? Thanks.
