the appliance. Push the water tank down until the water tank lid levels up with
the top of the appliance. Purge the water filter (see below: 'Inserting or Chan-
ging the Water Filter').

INSERTING OR CHANGING THE WATER FILTER

To guarantee long lasting proper working order of your espresso machine we recom-
mend to use the designated water filters and change the water filter regularly (see
table below). With the water hardness set correctly, we recommend to change the
water filter with every third descaling process.
Water Hardness
low up to 50 mg/l
medium 50 - 350 mg/l
high above 350 mg/l
Please, use the designated Gastroback water filters only. Contact your vendor for
further reference.
Note
If your water hardness is 4 or 5 (high; approx. 350 mg/l or more), we strongly
recommend to use an alternate water source (e.g. low-mineral table water). Low-
mineral table water will extend both the life of your water filter and the descaling
intervals as well as giving superior taste. You can get information on the water
hardness via the supplier of your water (water works or bottling plant).
1. Remove the water tank from the back of the appliance by grasping the water
tank at its sides and pulling it upwards vertically. Pour out any remaining water.
Pull the water filter out of the water tank.
2. Clean and rinse the water tank thoroughly (see: 'Replacing the Water Filter and
Cleaning the Water Tank').
3. Align the circular opening in the base of the new water filter with the valve inside
the water tank. Carefully press the water filter down. Then fill the water tank up
to the MAX filling level with fresh, cold water.
4. Slide the water tank vertically downwards at the back of the espresso machine.
Push the water tank down until the water tank lid levels up with the top of the
appliance. With the water tank installed correctly, the valves at the bottom of the
water tank and in the base of the machine will open automatically. Prepare the
appliance for operation and switch on (see: 'Preparation'). Wait until operating
temperature is reached (power button is illuminated continuously).

5. Place a sufficiently large and heat-resistant bowl (at least 1/2 litres) onto the drip
tray and point the steam wand into the bowl.
6. Turn the hot water/steam switch clockwise to pump out hot water via the steam
wand. Leave the appliance operate until the hot water stops automatically. Turn
the hot water/steam switch back to the vertical position.
7. Empty the bowl and place it onto the drip tray again. Wait until the appliance
reaches the correct operating temperature again (power button is illuminated
continuously).
8. For completely washing out any small particles of activated carbon from the
water filter, repeat the steps 5 to 7 3-5 times. If required, do not forget to refill
the water tank intermediately.
9. Fill the water tank with cold water.

ADJUSTING THE WATER HARDNESS

You can set the DESCALING warning time to one of the three water hardness levels
(high, middle, or low, see: 'Descaling the Machine').
Note
The espresso machine is delivered with the water hardness set to high. However,
the DESCALING indicator is only for information and will illuminate as soon as the
water volume set as a default is reached. The DESCALING indicator will remain
illuminated until it is reset manually. It will not interfere with any operation of the
espresso machine.
Note
After switching on the appliance, wait until the appliance reached operating tem-
perature (power button is illuminated continuously). No settings can be made duri-
ng the heating process (power button is flashing).
The water hardness levels are assigned to the buttons of the appliance as given in
the following table.
Button Water hardness
1 cup button low
2 cups button medium
