Jandy Lite 2 Lights but then you hear clicking w/tiny bit of shaking, temp elevates from 62 to 98 & shuts down. Sounds like it’s coming from side where pipe takes water in and out. System then restarts. Any ideas which part this is? This is our 1st time opening our pool as we’ve just purchased home. Shame there’s already an issue but it is what it is...lol! Welcome to life, huh? Any thoughts would be much appreciated. Thanks a million times over :)
