Descaling Logic - Machine Blockage; Coffee Module; Milk Module - Nespresso Momento 120 Service Manual

7.3.2 Descaling Logic – Machine Blockage
A descaling alert gets triggered on the machine and shown on the MMI based on:
• the "threshold" computation based on the water hardness and consumption
(recommended descaling)
• the required descaling
If a descaling alert is triggered,
- the MMI shows a steady descaling icon for the initial 15 days after the alert,
- after 15 days have passed without a descaling performed by the user, the des-
caling icon starts blinking,
- after another 15 days without descaling, the machine is blocked and descaling
is forced before operation is possible again.
