although water is still in
the tank.
Steam is discharged even
after the steam button
has been released.
Tank cap cannot be
opened.
POWER steamer 2:
When a unit is cold, the
manometer indicates vac-
uum pressure.
Calcium deposits in the

Cause
• Calcium deposits have collected in the
pressure tank or too much sludge has
collected�
• The calcification indicator was ignored.
• The solenoid valve is jammed due to
particles of dirt�
• The pressure tank is still pressurized�
• The vapor pressure of the water at room
temperature is lower than that of air�
• Excess water was not removed after
filling.
• The inlet pressure is so low that the con-
tainer cannot be filled in the permitted
maximum pump run time�
• Simmering water is drawn into the
steam outlet opening because the pres-
sure tank has been filled to the maxi-
mum�
Meaning
On Tank empty
Flashing If the unit is switched off:
The temperature of the pressure tank is still above 80°C�
On Heating / reheating
Flashing Waiting for cooling with new water before reheating�
On Working pressure reached�
Flashing slowly Steam outlet function activated�
Flashing quickly Rinsing in progress (POWER steamer 2 only)�
Flashing Calcification limit reached.
Flashing 2x (*) POWER steamer 2 only:
During operation, the mains water connection no longer has any water
pressure�
• Rinse / de-scale the pressure tank (see Chap� 6�3
and 6�4)�
• Remove the cover in the middle and tap the sole-
noid valve, for example using the handle of a screw-
driver�
• Do not force open the tank cap!
• Release all the pressure, e�g�, using the steam out-
let function (see Chap� 5�4), or if the tank is empty
(red indicator is on) by pressing the steam button�
• No action required�
• Switch on the unit and briefly press the steam but-
ton� Pressure compensation is achieved by opening
the solenoid valve�
• Wipe off calcium deposits.
• Always remove excess water after filling.
• No action required�
• This behavior resolves itself after working for a
short time�
• Only fill the unit with the recommended quantity of
water�
