MAINTENANCE AND CLEANING

It is important that the espresso machine is regularly cleaned. It will ensure

a high quality of the coffee brewed. We recommend that the machine is

cleaned after each brewing. Procedure:

Rinse the brew head unit. ●

Rinse the steam wand with steam ● (C).

Wipe the steam wand ● (C) clean with a damp cloth immediately after the

espresso machine has been used.

Take out the lter ● (H) from the handle (E) and wash it, clean the holes

of the lter (H).

and wash it, clean the holes of the lter ● (I).

Important: Never wash parts and accessories of the espresso machine in

a dishwasher.

Cleaning the drip tray (I) and the grid (J)

Take out the grid (J) and the drip tray (I) (23). Wash with water with the

addition of some mild washing-up liquid, rinse and dry.

Warning: Ensure that after taking out and replacing the drip tray (I) and

the grid (J) the insert is in the right place.

Cleaning the brew head unit, the lter holder and (E) and the lter (H)

Rinse the lter (H) and the lter holder (E) with warm water after each use

and dry.

To clean the brew head unit from used coffee, rinse it with water, wipe the

head and the internal ring with a damp cloth. If the holes of the lter are

blocked with coffee, use a delicate brush.

Rubber seal of the brew head

The seal of the brew head is at the bottom of the brew head unit and it

seals the lter holder (E) coffee is poured.

Warning: It is recommended that the lter holder (E) is not left in the brew

head unit during long breaks in the use of the espresso machine, as it may

reduce the durability of the seal.

It is natural that a seal loses its elasticity and needs replacing. A lack of

tightness between the lter holder (E) and the brew head (steam is visible

around the brew head unit when pouring espresso) is an indication that the

seal is worn out.

Warning: Contact the nearest authorised service center if you think

that the seal of the brew head unit needs replacing.

Outer elements

Wipe the appliance with a damp cloth and dry it. Do not use any brushes

or abrasive cleaning agents as they may scratch outer surfaces.

Cleaning the steam wand (C)

Keeping the steam wand (C) clean is essential to ensure the maximum

performance of the steam function. Deposits of e.g. dried milk on the wand

Important: Wipe the wand (C) clean with a damp cloth and rinse with

a little steam after each use.

Should milk have dried on the steam wand (C), wrap the wand (C) with

a clean damp cloth, place the wand (C) above the drip tray (I) and turn

on steam for about 10 seconds. Next, leave the cloth on the wand (C) for

about 5 minutes until it soaks. If there still is dirt on the wand, repeat the

procedure.

Important: Never clean the steam wand (C) with an abrasive scourer as it

may damage the wand.

DESCALING

Scale is a mineral build-up which naturally occurs on all appliances

connected with heating water. Therefore the espresso machine will require

descaling on a regular basis. It is recommended that scale is removed

from the espresso machine every 4-6 months, depending on the frequency

of use.

Descaling agents

The following agents are traditionally used for descaling espresso machines:

Espresso machine descaling tablets. ●

Special descaling liquid agents. ●

Vinegar solution. ●

Descaling the espresso machine

Warning: Ensure that the espresso machine is switched off and the

connecting cord is disconnected from the socket.

1. Take out the water tank and rinse it clean. Depending on the descaling

agent used, follow the steps below:

A. Espresso machine descaling tablets

Pour about 1l of warm water into the water tank and put in

a suitable number of descaling tablets, as recommended by the

manufacturer. When the tablets have dissolved (it takes about

5-7 minutes), replace the tank.

B. Descaling liquid

Pour about 1.5l of warm water into the water tank. Add a suitable

amount of the descaling agent, as recommended by the

manufacturer and replace the tank.

C. Vinegar solution

Pour about 1l warm vinegar solution into the water tank

(3.5 glassfuls of water, 0.5 glassful of 10% vinegar) and replace

the tank.

2. If the lter holder (E) is in the brew head unit, take it out, rinse

thoroughly under running water and put it aside.

3. Using a screwdriver, unscrew the lter from the bottom of the lter

holder unit.

4. Take out the lter, the washer, the screw, and the seal and put them

aside in a safe place.

Important: Be careful not to lose the lter, the washer, the screw or

the seal after disassembling the brew head unit.

5. Using a small delicate brush, clean the brewing area of the head

removing all coffee particles.

6. Place a sufciently big container under the brew head unit.

7. Insert the plug of the connecting cord in a mains socket and switch on

the espresso machine by pressing button (M).

Warning: Remember that if the standby pilot light (N) ashes, it means

that the espresso machine is in the course of reaching the operating

temperature. The moment the espresso machine has reached the

right temperature, the standby pilot light (N) will stop ashing and will

come off. It indicates that the espresso machine has reached the right

temperature and is ready to operate.

8. Turn the regulator knob (K) into the espresso position and allow

half of the decaling solution to ow through the brew head unit.

Important: Do not run the descaling solution through the steam

wand (C).

Warning: Depending on the size of the container under the brew

head unit, it may be necessary to empty it during the process.

9. Turn the regulator knob (K) into position 0 to stop the ow (after about

half of the solution has owed through) and then press button (M)

and turn off the appliance.

10. Leave the espresso machine for about 10-15 minutes thus allowing

the descaling agent to work.

11. Next, press button (M). This will turn on the espresso machine.

12. Turn the regulator knob (K) into the espresso position and allow

the rest of the descaling solution to ow through the brew head unit.

13. Take out the water tank from the appliance and rinse it thoroughly

under running water. Check that all traces of the descaling solution

have been removed. Fill up the tank with fresh water (1) and place it

in the espresso machine.

14. Turn on the espresso machine with button (M) and turn the regulator

knob (K) into the espresso position . Allow all of the fresh water to

ow through the brew head. Repeat the procedure twice.

Warning: Depending on the size of the container under the brew

head unit, it may be necessary to empty it during the process.

15. When the process has nished, remove the container from under the

brew head and wipe the whole brew head unit thoroughly.

16. Carefully install the rubber seal, the lter, and the washer in the brew

head, following their disassembling procedure in reverse order. Using

a screwdriver, tighten the fastening screw home.

17. Fill the tank up with fresh water (1) and replace it in the espresso

machine. The appliance is ready for further use.
