Checks and maintenance

Control and maintenance operations

To ensure perfect safety and efficiency of the machine
Not After maintenance and/or repair intervention,
the components used must ensure that the hygiene
and safety requirements initially provided for
the appliance are still met. These are met by
using original spare parts only. After repair or
replacement of components related to parts in
direct contact with water and food, a washing
procedure has to be carried out, as in the case of
first installation.
Using the machine display, check that the indicated
pump pressure is around 8-9 bar.
Check that the boiler pressure indicated on the
display is consistent with a programming value.
Check the dose of the ground coffee, which should
be about 6-7 gr. at a time, and adjust the amount
as necessary.
Check the degree of grinding and modify as
required.
Check the grinders for wear: they should be re-
placed if there is too much powder in the ground
coffee.
You should replace the flat grinders after every
400/500 kg of coffee. For conical grinders, replace
every 800/900 kg
