Before shutting down the machine (i.e. at night):

For the following operations the machine has to be switched on:

Rinsing the brewing head (“group”) – Fig. 1-6. With a small hard clean brush, give

the inside of the group a good scrub.

The group should be back flushed regularly. This means after each day, firstly,

remove the filter basket and then fit the blind filter into the handle.

Next fit the handle into the espresso machine.

NOTE: This filter basket has no holes so the water pressure will build up and the

water is very hot. Caution!

Press key (Fig. 3-1) and switch it off after 15 seconds.

The purpose of this is to push fresh brewing water back through the coffee brewing

head (group) and back out through the exhaust solenoid valve thus cleaning the

coffee brewing group of the machine.

Repeat this procedure several times, and each time you turn off switch Fig. 3-1

remove the filter holder and empty the water sitting in the blind filter. Repeat until the

discarded water is clean and fresh.

Next or weekly, put a small amount of special detergent for espresso machines into

the blind filter and repeat the process as above. Repeat this process until the

detergent runs clean into the drain tray via the exhaust solenoid.

Ensure that you back flush the machine once again so the detergent residues are

washed away.

For the following operations the machine has to be switched off, unplugged

and completely cooled down:

Clean showers, group gaskets and group flange with a clean brush (to be used only

for this purpose).

Cleaning the filter holder and the metal filter baskets:

With a small screw driver or teaspoon, flick out the filter basket from the handle.

Once you have the filter basket out, clean both the filter basket and the internal

surface of the handle with a pot scourer until both surfaces are clean from the black

coffee oils.

Should the oils in the handle have built up to excessive amounts, it may be necessary

to soak the handle and the metal filter basket in hot water with a cap full of special

detergent product for espresso machines for 30 minutes or so and then rinse

thoroughly in fresh water.

Wash metal filter baskets and filter handle in warm water adding a special detergent

product or espresso machines following the instruction’s of the specific product. It has

to be food quality and for this specific use with coffee machines.
