CLEANING & MAINTENANCE
Basic Cleaning
• Disconnect the machine before regular cleaning with a damp (NOT
WET) cloth and wipe dry afterwards. Never immerse machine in liquid.
Other parts, such as carafes, lids, brew baskets may be washed in the
normal way.
• DESCALE THE MACHINE REGULARLY. FAILING TO DESCALE WILL CAUSE
THE BOILER TO OVERHEAT AND EVENTUALLY THE FUSE TO TRIP.
If the descale light illuminates, the machine should be descaled
immediately.
Descaling instruction
• Unscrew the drainage plug – under the lid of the cold water container
– and turn the machine upside down to drain the residual water from
the boiler.
• Fill the container with the correctly diluted descaler.
• Do not switch the machine on, but simply allow the descaler to
gravity feed in the boiler from where it will work its way through the
system. A chemical reaction between the scale and the descaler –
clearly visible as foaming – forces the descaler through the boiler into
the brew basket/carafe.
TIP: if you unscrew the drainage plug under the lid of the cold water container, you
will see active foaming. For as long as that continues, there is still scale in the boiler! In
that case, simply pour some more cold descaler into the cold water tank to continue
descaling until the active foaming stops.
ATTENTION: NEVER turn the machine on with the screw cap on
the drainage plug open, as you could burn yourself!
• Depending on the amount of scale in the boiler, the descaling process
may take some time. The machine will however descale itself and
does not require you to stand over it whilst it happens.
• After descaling, boil at least three carafes of water through the
machine to remove all traces of descaling agent.
Protection from frost
• Unplug machine from the mains.
• Unscrew the drainage plug under the lid of cold water container.
• Remove all residual water from the machine by turning it upside
down.
• Before using the machine again, replace and tighten drainage plug.
