12. Boiler: Is the element responsible for heating the water that
comes from the tank to reach the adequate pressure steam.
This includes the following components:
► Heating element: Located in the interior of the boiler.
Resistance connections are (13) y (14).
► 2 NTCs: In the external sides of the boiler there are two
temperature sensors NTC type, that controls the filling
(activation time and stopping of the pump):
Lower NTC (16): controls the boiler filling during normal
operation
Top NTC (18): controls the initial filling and acts as
security against overheating.
at 25ºC
► Thermofuses (17): As security elements, the boiler has two
serially connected thermofuses that cut power to the
resistance in case of overheating.
► Water inlet (19): Hose that connects the pump with the boiler.
4.1.6 Solenoid valve
20. Solenoid valve: At the exit of the boiler there is (normally
closed) a solenoid valve, allowing you to dispense steam
according to the following levels:
Handle switches of the iron without pressing: solenoid valve
closed, and the flow of steam leaving the boiler is null.
Handle bottom switch of the iron whit pressing: solenoid
valve open, opening the way of normal steam flow towards
the iron.
Handle top switch of the iron whit pressing briefly: the PCB
sends open the solenoid valve 3 times short and followed
