NOTE
On all machines there is a high-limit thermostat to control the temperature of the heating elements
electrically: this thermostat limits the elements' temperature. When the temperature is above the
maximum level, the electrical power supply to the elements is cut. When this happens, the thermostat
must be reset by pushing the button located on it, once the element is cold. (The thermostat can be
accessed by removing the right panel on the machine.) In the case of machines with two boilers, there is
one for each element.
NOTE
All machines have a boiler level sensor. For machines with two boilers, the sensor is in the steam/hot
water boiler.
