My year old Hot Spot Majorca has begun tripping the GFI with increasing frequency. I've been back and forth with my dealer, and aside from putting in a new filter element (which didn't change anything), there's nothing to do but wait until his tech can get out here. It being New Years and all, that won't be until Wednesday. The breaker won't stay on at all anymore, I'm in southern CT, temps are slightly above freezing during the day, slightly below at nite, the water is still steamy. Should I be piling moving pads on top of the cover ?
