Descaling The Espresso Machine - SEB ALLEGRO COMBI Mode D'emploi

Cleaning the espresso and cappuccino maker
Before cleaning the appliance, turn it off, remove the plug and leave it to cool down.
The filter holder, the filter basket, the jug, the jug lid and the overflow tray cannot be washed in the
dishwasher. Only use hot water and soapy water. Never use accessories or abrasive products.
The machine itself can be wiped down with a damp cloth. Never plunge the device into water or any
other liquid. Clean the percolation head using a damp cloth to remove any residual ground coffee. If
there is water left in the boiler, leave it to cool, take off all the removable parts and then empty the water
out of the hole at the top by turning the machine upside down.
Cleaning the cappuccino nozzle
Clean the nozzle each time it is used with milk, otherwise the inside of the nozzle will block up and milk
deposits dry on the surface and are rather difficult to clean later on.
- If the nozzle is blocked, remove the plastic base of the cappuccino nozzle (figure 20), once the
machine is cold, and then unscrew the end of the nozzle (figure 21).
Use a needle to remove the particles of milk and rinse under the tap. Put the end of the nozzle back and
ensure it is tightly screwed on. Wipe the outside of the nozzle with a damp cloth. Keep the cloth over the
end of the nozzle, to cover it, and open the steam nozzle. Let the steam escape into the cloth for a second
or two, then close the nozzle again. All the residual milk should now have been removed. Rinse the plastic
base of the cappuccino nozzle in warm water. If the openings through which the air is drawn in are
blocked up, you can use a little needle to clean them out.
Cleaning the drip tray
- The overflow tray and the grid over the top can
be cleaned by removing the grid (figure 22).

Descaling the espresso machine

The limited warranty does not cover machines that have ceased to function or which function badly
because they have not been properly descaled.
- Because of the acidic substances that are used for descaling, it is recommended that you protect your
work surfaces and your sink during this operation, in particular if they are made of marble or stone.
Put the machine on a towel, a tablecloth or a tray.
The machine must be descaled regularly. The frequency of this operation will depend on how hard your
water is and how often you use it.
Before descaling, you must first of all unscrew the grid inside the percolation head.
1. Remove the scale and the coffee residue from the grid and the percolation head.
2. Remove the plastic base of the cappuccino accessory (figure 20).
3. Dissolve a sachet of descaler solution in 300 ml of warm water and pour into the boiler. Place a
recipient under the percolation head and another under the steam nozzle.
(Remark: do not use the filter holder during the descaling).
4. Open the nozzle and turn the machine on. Let the descaling solution drip through the percolation
head and the nozzle.
5. Once the cycle has been completed, turn the machine off and leave it to cool down.
6. Repeat stages 4 and 5.
Fill the boiler up with fresh water and leave it to run through the system completely. Repeat this process.
Turn the machine off and leave it to cool down. Put the grid back in the percolation head and put the
plastic base of the cappuccino accessory back in place.
ATTENTION
Do not attempt to open or dismantle the body of
the machine.
