5–3. DESCALING
• We recommend that you descale the
machine according to how often it is
used and the water hardness, using
specific, readily available descalers that
can also be obtained from Authorised
Service Centres.
• Dissolve the descaler in water (1.5
litres) and then pour the solution into
the water tank (
1).
•
Make sure the filter holder is not
inserted.
• Place a suitable container under the
group head ( 5 ) and under the turbo
steam nozzle ( 6).
• Turn on the coffee / hot water switch
( 10 ) and allow the solution to flow out
of the group head ( 5 ) for about 15
seconds. Then turn off the coffee / hot
water switch.
• Move the steam switch ( 11) and the
coffee / hot water switch ( 10) to the on
position and slowly open the steam
knob ( 4 ) to allow water to exit from
the turbo steam nozzle ( 6 ) for a few
seconds and then stop.
• Wait a few minutes and repeat
the above steps until the tank is
completely empty
• To eliminate any residues of the
solution and scale, remove the water
tank ( 1 ), rinse it thoroughly, refill it with
clean water and put it back into the
machine.
• Turn on the coffee / hot water switch
( 10 ) and dispense water until the tank
is completely empty.
• Repeat the two previous points again.
