I have an outdoor Hydropool hot tub and have recently been having an issue with power. It seems that periodically a build up of 'gunk' (my technical term for it) builds up around one of the electrical connections to the heater and eventually causes the breaker to trip.
In the past I have been able to fix the problem by simply disconnecting the wires and wiping away the gunk with some paper towel. This typically happens only after quite intense rain storms but I'm not sure if it's related.
Is there a way to keep this from happening? or is it a sign of something more significant going on that I should get checked out.
