BEZZERA MAGICA - MITICA
MOD.
Problem
Coffee flow is excessive
The coffee supplied is
too cold
The coffee supplied is
warm
The coffee supplied is
too hot
Deposit the coffee on
the bottom of the cup
Diagnostics/Solution
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).
Possible causes:
1 - The filter holders are cold.
2 - The coffee has been ground too fine-
ly.
3 – The machine's water circuit is dirty
(limestone).
4 – The boiler's pressure is lower than 0.8
bar (0.08 MPa).
The coffee supplied is warm if the pres-
sure is normal, between 1 and 1.2 bar
(0.1 – 0.12 MPa). In this case, the pres-
sure value is not correct.
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 cooling.
3 – The machine was installed in a position
that does not allow air circulation
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).

Advices
In cases 1-2-3 adjust grind-
ing and/or dosing of coffee.
In the 4th case, a technician
must be consulted.
In case 1, keep the filter hold-
er assembled on the unit.
In case 2, alter the coffee
grinding.
In cases 3 - 4, call a special-
ised technician.
Call a specialized technician
to check the exhaust valve.
Meanwhile, to use the ma-
chine, 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. Perform this
operation daily when turning
on the machine.
In the 1st case, call a special-
ized technician.
In cases 2-3 reset the ma-
chine's cooling conditions.
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 techni-
cian.
