Important
The machine can only be dismantled by an authorizedtechnician.
A calcified machine may only be descaled by your specialized dealer because a partial
disassembly of the boiler and the tubing may be necessary to prevent the system from
being blocked by lime residues. A late descaling can cause substantial damage to the
machine.
Risk of injury
Be careful of the hot water spray while cleaning the brew group.
Important
Never use abrasive or chloric detergents!
Caution!
If you clean the brew group too often with cleaner, it may start squeaking. Do not clean it
too often with cleaner, you will degrease all the moving parts and they will wear out
quickly. It s better if you clean the brew group from time to time without detergent.
