Heating Element
The element in the absence of regular descaling and depending on the hardness of water used, presents with time deposits and deposits of limestone that can only be removed mechanically dismantled acting on deposits.
If the element is operated without water, fails, the copper that is melted and you create a short circuit. Resistance in a double filament (models without pressure and double-switch) usually occurs the rupture of a single filament. The resistance then heats little with the switch in position Minimo and go short with the switch in position Massimo.
