I just picked up a used hot tub no paper work came with it. all I know is that it has a balboa 53174-H Control Panel 1st thing was that the GFCI breaker kept tripping after reading some of the posts here found out that it was the heater. went picked up a new heater 5.5kw and a new pressure switch. I installed it now the breaker doesn’t trip. Pump and blower works but the new heater isn’t working no power also the red heat light is not on spent 2 days on this please help

Update fixed it------- the new pressure switch that I installed was bad put another new one in works temp 102 nice " title="Very Happy" />
