Remove the seal and operate the delivery system several times to
rinse the unit.

If, during delivery, the coffee drips out of the edges of the filter-holder
(G), this may be caused by the obstruction of the filter-holder delive-
ry hole, in which case the hole needs to be cleaned; if the problem
persists or, if when fitting the filter-holder into the brewing unit it
significantly moves beyond the unit centre, the group gasket needs
replacing (D).
In order to replace it, unscrew the jet fastening screw (E), remove the
jet (C) and the sprayer (B), and then use a screwdriver as a lever to
remove the round metal block (A) and subsequently the gasket (D).
After having removed the gasket, thoroughly clean the seat before
placing the new gasket, after which reinstall the component by fol-
lowing the above listed steps in reverse order.
14 - BOILER WATER REPLACEMENT
It is essential to replace the water contained in the boiler every
15-20 days, in order to eliminate the iron bacteria and the build-up
of various residues due to water stagnation.
Turn off the main switch (3), remove the drain basin grid (25) and
pull out the lower drain basin (24).
Open the drain tap placed under the level glass (with the boiler
under pressure) and let the water flow out of the boiler completely.
Close the tap again and repeat the start-up procedures by following
the steps outlined in the related section of this manual.
