DESCALING

Scale forms due to mineral content in the

water. Descaling is necessary to remove lime

scale from all surfaces and holes, thus

ensuring a perfect operation of valves,

heating controls and other important parts.

Note: due to the complexity of

the coffee machine’s hydraulic

circuit, the following descaling

cycles do not allow the descaling of

tubes.

In fact, easily accessible components

such as the brew group (14) and its

plastic connection are excluded.

The machine must be descaled every 3-4

months, according to the water hardness

degree.

A more frequent descaling is

recommended wherever the water

hardness degree is very high.

In case of hard water, a filter should be

used both to improve the coffee quality

and to protect the machine, thus reducing

the descaling frequency.

Note: for this purpose, use a

descaling product suitable for

coffee machines.

Never use vinegar to clean the

machine; it might damage it.

To facilitate the above operation, the

machine displays a message whenever it

needs descaling:

d e c a l c i f y

r e a d y f o r u s e

The machine will continue to dispense

coffee, but should be descaled as soon as

possible.
