Hello I have a Blue Ridge Spas Bought it used but it never got the water hot hot but warm enough where it wasnt cool . So this year i wanted to fill it up and when i did the Temp sense went out it wouldnt let the heater kick on . So i bought a new one and now the heater is on and when i put the dry sense in the hole where it goes it shows the water like 95 and the heater kicks off . But the water is luke warm .
