• If the descaling cycle is not completed correctly (e.g. no
electricity) we recommend repeating the cycle;
• If the water tank has not been filled to the MAX level, at the
end of descaling, the appliance requests a further rinse to
guarantee that the descaler solution has been completely
eliminated from the machine's internal circuits.
Repair of damage to the coffee maker caused by limescale is not
covered by the guarantee unless descaling is performed regular-
ly as described above.
