5/2 Service and maintenance
5/2.1 Introduction
Small professional coffee machines require regular maintenance and descaling.
Apart from regular cleaning by the user/operator, the coffee machine must be
descaled by the user/operator at the intervals shown.
Timing of descaling is calculated by the coffee machine. This depends upon the
settings for the degree of hardness of the local mains water and whether or not
awater filter is fitted.
Descaling:
When prompted on the display, descaling can be carried out by the user/operator.
Service maintenance:
Service maintenance every 7,000cycles for WMF800/900, every 10,000cycles for
1000S/1000proS. The service maintenance may be performed only by trained staff
or by WMFService. Safety checks must be carried out.
5/2.2 Safety checks during maintenance
By carrying out maintenance, the service engineer takes on the operator’s responsi-
bilities to ensure the safety of the coffee machine.
In particular, he must:
• check the electrical safety devices, e. g. protective earth connections, isolation of
primary voltage cables, casing and casing screw connections, temperature limiters
on boilers,
• check the safety of the pressure container (s), including connections (corrosion,
leaks),
• replace the safety valve (s) as specified.
These checks must be documented. The completion of the maintenance must be
recorded in writing and in the appropriate form (incl. name and date).
