Chapter 7 Maintenance
Please observe that this is a professional industrial coffee
machine which needs regular maintenance and descaling.
Timing of descaling is calculated by the machine and
depends on the degree of hardness of the local mains
water and whether or not a filter is fitted.
The maintenance schedule is based on the degree of use
of the machine and is shown on the display. The coffee
machine can continue to be used after the maintenance
message, but the service work should be performed soon
in order to ensure functional reliability and to avoid
subsequent damages.
