Ventilation system

The WMF 5000S requires 2 different fans

Fan, power stage:
A powerful (1.68 W) fan ensures a low ambient temperature of the power stage.
This fan pumps the air into the inside of the machine from the rear cover to the power stage. From here, the air is sent
out again via the discharge.
At the same time, this prevents steam from reaching the power stage via the discharge

Instructions:
The service life of the power stage is reduced by high ambient temperatures. For example, when using a low-power or
a fault fan.

Machine suction
The "quiet fan" (0.74 W) diverts residual moisture from the brewing chamber (coffee grounds) or chocolate area via the
rear cover
