Have a sta-right natural gas heater SR333 Max-e thermal. Pool and Spa combo. Today control panel on heater was non-responsive just blinking "888". Have had no problems until today. Also, have a spa side control and in-house control panel also non-responsive. In-house control panel had power but now a blank screen. Thought maybe loose connections but reconnected and checked for a loose connection. Reset breaker but still same result. All are sta-right and all were installed with pool in 2005. see pics below. Any help greatly appreciated! thanks Control Panel?? Power to unit is fine. Power to all jandy valves is fine also.
