Hello I have some problem with my spa: Jacuzzi Model: E781VM maax spas Controller: Balboa 760E GFCI: hager model CDC440J. Lights controller: SloanLED LiquaLED Control 40 1. When I dont use a lights, heater functionally normal with jets etc.` When I don`t use a heater, lights functionally normal with jest etc. When spa lights are on and I switch on heat, trips GFCI (hager model CDC440J). I try to disconnect a light from mainboard but it`s still the same, when I switch lights on [with disconnected controler or not] when heater is on, GFCII is triggered. please, have you got some ideas what to check? I have tried: disconnect light controller from board, disconnect ozone/uv, disconnects lights from lights controller. 2. Circulation Pump on standard mode: [in fast speed] functional normal [in slow speed] stopped after 10s-10min, DR/LF fail.
