with a simultaneous catalysis cycle.
Descaling
Periodically the display will prompt you to
perform the boiler descaling procedure.
Preliminary operations
In case there is residual water inside the
reservoir:
1. Open the door.
2. Place a jug or a container on the open
door.
3. Pull the loading nozzle out of its housing.
4. Press the START button to start draining
the water into the jug (or container).
Residual water begins to drain into the jug (or
container).
5. Wait for the end of the drain flow.
6. Empty the water in the jug (or container).
7. Touch the CONFIRM button to
continue the function.
Reservoir filling
1. Mix 100 g of citric acid with 650 ml of
water in a jug.
2. Pull the loading nozzle out of its housing.
3. Place the end of the tube at the bottom of
the jug (or container).
4. Touch the START button to start filling
the reservoir of the appliance with the
descaling solution.
5. In the end, shake the loading nozzle to
remove any remaining water.
6. Place the loading nozzle place in its
housing.
7. Remove the jug (or container).
Boiler descaling function
1. Close the door
2. Descaling starts.
At the end of the descaling process the display
shows the request to drain the water softener.
Reservoir draining
1. Open the door
2. Place a jug or a container on the open
door.
3. Pull the loading nozzle out of its housing.
4. Press the START button to start draining
the water softener into the jug (or container).
The descaling solution begins to flow into the
jug.
5. Wait for the end of the drain flow.
6. Empty the descaling solution in the jug (or
container).
Cleaning the reservoir and hydraulic circuit
Once the water softener has been drained, the
appliance starts the cleaning procedure for the
reservoir and the hydraulic circuit.
We recommend wearing rubber gloves
for these operations.
For easier manual cleaning of parts that
are difficult to reach, we recommend
removing the door.
The presence of scale due to lack of
descaling can compromise correct
operation of the appliance in the long
term.
Descaling is a long process (more than
one hour) that requires the user to be
present in front of the appliance.
We recommend performing descaling
every time this is indicated on the
display in order to keep the boiler in
perfect operating condition.
Depending on conditions, the system
will show if the appliance can perform
standard functions or if a descaling and
cleaning process of the hydraulic circuit
is required.
From now on, it will no longer be
possible to cancel the descaling
process.
Do not use lactic acid or other
descaling agents.
Take care: the descaling solution may
be still hot.
Use cold tap water which is not too
hard, softened water or still mineral
water.
Do not use distilled water, tap water
with a high chloride content (> 40 mg/
l), or other liquids.
