14.2 – FILTER AND FILTER-HOLDER CLEANING
Frequently check the filter holes to remove any coffee deposits.
Prepare about a litre of boiling water with four teaspoons of coffee-
machine detergent in a suitable container, and immerse in this
solution the filters and filter-holders for 20-30 minutes; then rinse
thoroughly under running water.
14.3 – DRAIN TRAY CLEANING
Remove the drain try grid ( 25 ) and pull out the drain tray ( 24 ) in
order to clean it from coffee powder residues.
14.4 – CASING CLEANING
Use a damp, non abrasive cloth, without alcohol or solvents, to
avoid damaging the sides, the base and any painted parts.
Important! The machine can not be immerse in water
and can not be cleaned with jets’ water.
15 – REPLACING THE GROUP GASKET
If, during delivery, the coffee drips out of the edges of the filter-
holder), this may be caused by the obstruction of the filter-holder
delivery 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).
15.1 – VASARI S - SV MODELS
For the replacement, it is necessary to lever with a screwdriver for
the removal of the seal (B) and the shower (A). After removing the
seal and hand shower, properly clean the seat before reassembling
the new parts.
15.2 – VASARI L MODEL
For the replacement, it is necessary to lever with a screwdriver for
the removal of the seal (B) and the shower (A). After removing the
seal and hand shower, properly clean the seat before reassembling
the new parts.
16 – 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 ( 1 ), 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 comple-
tely. Close the tap again and repeat the start-up procedures by
following the steps outlined in the related section of this manual.
17 – USE OF THE SOFTENER
Calcium and magnesium contained in the water circulating insi-
de the boiler and brewing unit circuits damage the machine.
The softener dissolves the calcium and magnesium, which settle on the
resins therein contained.
To prevent the build-up of deposits from saturating the resins, thus limi-
ting their functions, these need to be regenerated at regular intervals
according to the following criteria:
- 8 litre softener for 40 French degree HARDness water
• up to 400 cups of coffee/day, every 10 days
• up to 800 cups of coffee/day, every 5 days
• up to 1000 cups of coffee/day, every 3 days
- 12 litre softener, for 40 French degree HARDness water
• up to 500 cups of coffee/day, every 15 days
• up to 1000 cups of coffee/day, every 7 days
• up to 1500 cups of coffee/day, every 5 days
• up to 2000 cups of coffee/day, every 3 days.
Failure to comply with the above regeneration timings will prejudice the
thermal and mechanical functions of the machine and the taste of the
coffee, owing to the formation of scale.
For regeneration, proceed as follows:
Place an empty container, having a capacity of at least two litres, under
pipe ( e ), turn the ( c ) and ( d ) handles to the right, unscrew the ( g ) lid
and wait for the water to fully flow out of pipe ( e ), Introduce 1.5 Kg. of
cooking salt for the 8 litre model or 2 Kg. of salt for the 12 litre model,
place the lid back in place and move the ( c ) handle from right to left;
let the salted water flow out of the ( f ) pipe and wait until the water has
become fresh again (the cycle takes approximately 90 minutes).
