7. 4 TH E PUMP IN G EL EME NT
The pump is located on the left side of
the machine. The duration of the pump
depends on the amount of daily work and
the quality of the water. The machine pres-
sure set by the factory is ideal for the
extraction of the coffee: 9 bar.
WHEN TO REPLACE
It is noisy: if the impurities enter inside
•
the pump, the blades of the impeller may
block, therefore making it impossible to
load water.
Pressure not adjustable: with time the
•
impeller blades can wear out, therefore
if it is not possible to adjust the pressure
with the appropriate wheel it would be
necessary.
• Pressure fluctuation during dispensing:
the bypass or the impeller are damaged.
