1. Preventive Maintenance
Preventive maintenance (PM) ensures a continuous good quality of coffee products and reduces the
unscheduled break downs of the coffee machine. During preventive maintenance recommended services
will be done and necessary spare parts will be exchanged. Moreover it simplifies the organisation of the
maintenance and the spare parts logistics.
The bases for preventing maintenance are our service kits, along with all necessary spare parts. These
are available as “PM Service kit” and “PM Extension kit”.
The preventive maintenance is controlled by the number of brewing cycles, counted in the coffee
machine. Reaching the number of cycles, the coffee machine is indicating following message in the
display "PM Service Req.".
Egro Coffee System AG recommends adjusting the maximum brewing cycles for preventive maintenance
to 15’000 cycles. For coffee machines with the brewing unit “NBUP” (New Brewing Unit Project) the
number of cycles will be with 25’000.
The brewing cycles depend on various criteria as regularity of brewing, composition of water, cleaning
product, climatic conditions, etc. Egro Coffee System AG recommend, in case of unfavorable conditions,
to adjust the number of brewing cycles.
2. Programming manual
Put the machine in programming mode (mode 4).
Readout the brewing cycles: The parameter "P-Serv" informs how many brewing cycles the coffee
machine has done, since the last maintenance.

Adjust the maximum cycles: By entering the maximum number of brewing cycles the service counter is
activated. The input of the value 15 corresponds with 15'000 brewing cycles.
With reaching of this 15'000 brewing cycles the display shows the message "PM Service Req." and the
customer has to inform the service organization.
The number of brewing cycles has to be adapted depending upon application and environment of the
coffee machine.
Reset the brewing cycles: After preventive maintenance was accomplished, the cycle counter will be
reset to zero and activated again.
