GFCI trips when I turn hot tub heater on.

Hello I recently got a used hot tub all the parts inside are Hercules brand. everything works except for the heat. as soon as I turn the dial to put the heat on it trips off the gfci. the relay never pulls in. wasn't sure if that could be the issue. so I disconnected the wires to go the heater. so I turn the temp up the relay pulls in and no issues. Not sure if that means the relay is good or bad.
thanks for any help

Welcome to the forums! From what you are describing it appears the heater is part of a ground fault. GFCIs don't trip on overload, but on ground fault. Test the hot leads to the heater to ground with an ohm meter to see if there is continuity.

You should check the two connections for continuity. If you have continuity the element is not open.

Then you need to check from each terminal to the metal heater case. If either terminal shows any continuity then the element is shorted to ground and needs to be replaced,

You have a bad heater element and it needs to be replaced.
