Descaling the espresso maker
1. Power off the appliance, then fill the espresso maker's water tank with 600ml of lime juice available from
supermarkets, made up of at least 50% lime concentrate. Do not use lime juice containing less lime
concentrate. Do not dilute the lime juice by adding water. The liquid must reach the upper edge of the tank,
just short of overflowing. When the juice is in the tank, screw the cap on as you would when making coffee.
2. Attach the filter holder to the brewing head (without ground coffee), put the jug under the filter holder with
the lid on, and set the control button of the appliance to coffee making. Warning! never connect the coffee
maker to the mains when descaling with lime juice, always carry out this process with the appliance powered
off, the water reservoir cold, and at room temperature!
3. Leave the lemon concentrate in the water tank for 10-12 hours. You should remove the cover of the water
tank and leave it open for the last 2-3 hours of de-scaling. (You may notice lemon concentrate dripping into
the coffee pot, which shows that limescale deposits have been dissolved).
4. After 10-12 of de-scaling, pour out the lemon concentrate through the top of the water tank. Take care not to
let the lemon concentrate drip into other parts of the appliance. Wipe any lemon concentrate off the cover
with a dry cloth.
Attention! Never heat or brew the lemon concentrate!
The anti-scale outlet filter should now be removed from inside the brewing head for cleaning. (This is
particularly important in a ‘hard water’ area). The cross-head screw that holds the filter should be unscrewed
with an appropriate screwdriver. Ensure the appliance remains disconnected when doing this. Remove any
limescale and coffee residue from the outlet and from the filter.
Important: if the fixing screw cannot be removed due to limescale deposits, do not force it but contact a
specialist engineer for assistance.
5. When you have finished cleaning the brewing head and the filter, replace the filter and fix it in place with the
screw. Now fill the water tank with fresh water, switch on the appliance and complete a ‘brewing cycle’ but
without using any coffee. After the water has passed through, empty it from the coffee pot and repeat the
process. This will remove any lemon concentrate, leaving the appliance ready for daily use.
Attention!
If this de-scaling procedure isn’t successful, you will need to contact a specialist engineer to have
the appliance cleaned. This should not be necessary if you carry out regular de-scaling as
described above.
Repairs to any damage caused by scale or by carrying out the de-scaling procedure are not
covered by the product guarantee.
Always pour out the lemon concentrate used for de-scaling and the water used for rinsing. Do
not drink it!
Don’t leave the lemon concentrate in the appliance for longer than 12 hours. Always clean the
appliance with fresh water (as described) after using the lemon concentrate.

Instructions for handling the glass coffee pot:
• The glass coffee pot can break or crack if the following instructions are not followed:
a) The coffee pot has only been designed for use with this coffee maker. Do not use it for any other purposes.
b) Never put the coffee pot on an electric or gas hob. Never put the coffee pot in a microwave oven.
c) Do not place a hot coffee pot on a wet or cold surface.
d) Never clean the pot with a scouring liquid, with a scouring pad or with any other scouring material. Always
wash the coffee pot by hand and never put it in a dishwasher. Take particular care not to drop or knock it.
e) If you are making several batches of coffee, always pour out any remaining coffee and allow the pot to cool
down before making any more. A hot glass pot can crack if it is filled with cold water.
Important: Never use the coffee pot if the glass is cracked or chipped. Never use it if the handle is loose or
has moved.
De-scaling the coffee maker:
• If the coffee maker is generating large amounts of steam or is taking longer than usual to brew your coffee, it
is time to de-scale the appliance. Scale is created when calcium (limescale) and other minerals separate from
water during heating. This can affect the flavour of your coffee, increase the brewing time and may even
cause the appliance to become faulty.
• To prevent the unwanted effects of limescale, you should de-scale the appliance regularly. This should be
carried out at least 10-12 times per year. (This assumes the hardness of tap water is a maximum 18°dH /
22.5°Clarke). In areas where the tap water is harder than 18°dH (22.5°Clarke), de-scaling should be carried
out 12-15 times per year. If you make coffee several times a day or live in an area where tap water is very
hard, you should de-scale the appliance after every 30-40 brewing cycles. Your local water company will be
able to answer any questions about water hardness. Regular de-scaling needs to be carried out by the user
and is not covered by the product guarantee.
Descaling the filter coffee maker:
1. Power off the filter coffee maker and let it cool down completely, then fill the water tank with 200ml of lime
juice available from supermarkets, made up of at least 50% lime concentrate. Do not use lime juice containing
less lime concentrate. Do not dilute the lime juice by adding water.
2. Leave the lime juice in the water tank for 6-8 hours, then pour away.
3. After descaling, discard the lime juice from the filter coffee maker's water tank. When discarding the juice
take care not to let it get into the appliance, and if it gets onto the casing, wipe it off immediately. Warning!
Never boil the lime juice.
4. Fill the water tank with fresh water up to the MAX level, connect the appliance to the mains and after turning
the coffee maker on, run all of it through the coffee maker without putting ground coffee into the filter. After
rinsing the tank and the heating unit, the appliance is now ready for use.
