Yeah, i do know bout liquids getting on it, that's why i always check if everything's okay with the probes.. Though what surprises me is that i never had any issue like that before for whole 2 months, can a problem actually show up so late? Not saying i'm going to be stubborn and impossible to prove wrong, i just wonder. I will try any option i have to get everything back in place, but should i keep both of the thermostats' and thermometer's probes under between the tub and heat mat?
