cleaning & maintenance
Regular cleaning will prolong the life of your appliance and will
guarantee optimal brewing results.
Before cleaning:
• Check if the appliance is switched off and the plug is
unplugged.
• Clean the outside of the appliance regularly with only a damp
cloth or sponge and dry it with a dry cloth. Never use any
abrasives. Never place the appliance in water or under
running water.
• Clean the thermos jug and filterholder with warm water and
some washing-up liquid. Dry the parts thoroughly before you
place them back. Never wash the thermos jug and filterholder
in the dishwasher.

descaling

Regular descaling will prolong the life of your appliance and will
guarantee optimal brewing results. The coffeemaker must be
descaled at regular intervals: every 40 cycles for very hard water
(about once a month) and every 80 cycles for soft water (about
once every 2 months). But more frequent descaling may be
necessary if you notice: an increase in noise when boiling or if
brewing takes longer. You can use either a sachet of descaler or
cleaining vinegar.
When you use a descaler for coffeemakers, follow the
instructions on the package.
When you are using cleaning vinegar do as follows:
1. Switch off the appliance, unplug it and let it cool down.
Remove all the separate parts (thermos jug and filterholder).
2. To remove excess water turn the machine upside down over
the sink.
3. Fill the waterreservoir up to halve with cold vinegar and add
fresh, cold water to the maximum level. Place the thermos jug
on the warmingplate and place the filterholder with an empty
paper filter on the holder.
4. Switch the appliance on.
5. Allow the equivalent of halve the amount to run through
into the thermos jug. Then stop the coffeemaker. Leave the
remaining mixture in the coffeemaker to work for 15 minutes.
Restart the coffeemaker to finish the runthrough.
6. Rinse the coffeemaker by running it 2 or 3 times with fresh
water (full water tank and without coffee).
Attention! If you haven't used the coffeemachine for a while, for
instance if you have been away on a holiday, you should remove
all the separate parts for cleaning and rinse the coffeemachine
with fresh water. Place the cleaned parts in the machine. This
prevents an additional taste.
