If the machine is not heating , check the following:
a- the
thermos
tat (mo
unted
on the
heat
exchan
ger and
steam
boiler if
present
).
b- the
heating
element
(on the
lower
side, not
seen in
the
picture).
c- the
thermof
use
d- the electronic sensor that initially brings water to temperature for espresso.
Finally, before replacing the top cover, make an espresso with coffee. To do so,
use the preground cycle with ground coffee or hold the bean hopper on the
grinder inlet and add beans in the bean hopper just enough for one espresso
(excess beans will spill around and inside and be difficult to clean, especially
from around the doser assembly. (Vacuum the spilled beans out)
If all functions are working good, the coffee grind is like the table salt grain, and
still the espresso is not dispensed, the chances are that the
1- pump is weak and unable to exert the pressure necessary to pump water
through the tamped coffee grounds. Replace the pump.
2- the heat exchanger outlet nozzle is blocked or its lower end is broken. Replace
the nozzle.
3- Th brew group is blocked. Clean the shower screen & the valve under the
outlet nozzle flange.
To remove the pump
, avoid removing the pump mounting pads (it is a lot of
work).
