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
Amount of Water
low
up to 50 mg/l
approx. 60 litres
medium
50 - 350 mg/l
approx. 35 litres
high
above 350 mg/l
approx. 20 litres
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).
