0 Like me your wiring in the boiler probably melted and short circuited keeping the circuit on. This happened to min twice until I replaced all the wire with high heat wire designed for electric stove elements that is wrapped in heat-insulating protective covering made of woven ceramic. Ope the unit and check the wires between relays at the bottom area of the unit. The wires to the heating elements come already high heat insulated but not between the relays. I can't believe that the CSA has not required Chromalox to recall and upgrade this fire hazard!
