The safety lock can only be opened for filling in water if
there is less then 0.2 bar inner pressure in the pressure
tank. If the pressure is higher, it must be reduced via the
steam gun first.
The refill tank is unheated and depressurised.
The water level is monitored by the level sensor.
If the plug is plugged into the device, both heaters heat the
water in the pressure tank.
If the modular accessory plug is not plugged in, only the
heating 1500 W is heating.
The pressure regulator switches the heating off as soon as
the set steam pressure has been reached.
The level sensor monitors the water level in the pressure
tank. If the water level falls under a certain level due to the
steam consumption, the water pump is switched on. This
delivers water from the refill tank to the pressure tank until
the water level there has increased so much that the level
sensor switches the water pump off again.
When the water in the refill tank is used, an audible signal
sounds 8 times and the indicator light "water shortage refill
tank" lights up.
The water can immediately be refilled there without switch-
ing off the heating.
If water and steam are completely consumed, the thermo-
stat water shortage switches off the heating. At the lowest
point of the pressure tank, underneath the heating, a small
amount of water remains. This is enough to reduce the
pressure tank temperature quickly to below 100°C. This
way, there is no risk that water splashes back upon refilling
the pressure tank and scalds the user.
