symptomsThe machine overheats, once before replacing the pressure switch solved the problem.This time however after the installing the new switch only the pump worked not the heater. I reinstalled the old switch and it once again overheated. I called Burgess Enterprises in Seattle and they sent me out another switch but after installing it the same results as the first replacement occurred.
