MOD. BEZZERA MATRIX-DUO
Coffee flow is excessive The coffee is distributed too
quickly and the cream is lighter
than usual.
Possible causes:
1 - The coffee has been ground
too coarsely.
2 - The coffee in the filter holder
is not pressed down enough.
3 - There is too little coffee in the
filter holder.
4 The pressure supplied by the
pump is high (> 10 bar – 1
MPa).
In cases 1-2-3 adjust grinding
and/or dosing of coffee.
In the 4th case, a technician
must be consulted.
The coffee supplied is too cold Possible causes:
1 - The filter holders are cold.
2 - The coffee has been ground
too finely.
3 The machine’s water circuit is
dirty (limestone).
4 – The boiler’s pressure is lower
than 0.8 bar (0.08 MPa).
In case 1, keep the filter holder
assembled on the unit.
In case 2, alter the coffee
grinding.
In cases 3 - 4, call a specialised
technician.
The coffee supplied is warm The coffee supplied is warm if
the pressure is normal, between
1 and 1.2 bar (0.1 – 0.12 MPa).
In this case, the pressure value is
not correct.
Call a specialized technician to
check the exhaust valve. Mean-
while, to use the machine,
open the steam tap (Fig. 01;
pos 9); the boiler’s pressure will
drop to zero, thus causing the
enabling of the resistor and the
increase of temperature. Per-
form this operation daily when
turning on the machine.
The coffee supplied is too hot Possible causes:
1 The boiler’s pressure is higher
than 1.3 bar (0.13 MPa).
2 The machine is covered by
something that prevents cool-
ing.
3 The machine was installed in
a position that does not allow
air circulation
In the 1st case, call a special-
ized technician.
In cases 2-3 reset the ma-
chine’s cooling conditions.
Deposit the coffee on the bot-
tom of the cup
Possible causes:
1 The grinding of the coffee is
too thin.
2 - The filter holder is dirty inside
or the filter is damaged.
3 The millstones of the grinder
are worn out.
4 The pump’s pressure is too
high (> 10 bar – 1 MPa).
The 1st case can be solved by
adjusting the grinder.
In the 2nd case, clean the filter
holder or substitute the filter.
In cases 3-4 call a technician.
