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. ●

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

espresso machine has been used.

Take out the ﬁ lter from the handle and wash it, clean the holes of the

●

ﬁ lter.

Empty and rinse the drip tray.

●

Important: Never wash parts and accessories of the espresso machine

in a dishwasher.

Cleaning the drip tray and the grid

Take out the grid and the drip tray (46) (47). 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 and grid

the insert is in the right place (48).

Cleaning the brew head unit, the ﬁ lter holder and the ﬁ lter

Rinse the ﬁ lter and the ﬁ lter holder with warm water and dry after each

use.

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 ﬁ lter are

blocked with coffee, use a delicate brush.

Important: If the holes of the ﬁ lter are still blocked, use the grey pin placed

on the base, under the water tank (49) (50). Insert the cleaning pin into the

holes in the bottom part of the ﬁ lter (51).

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 ﬁ lter holder when coffee is poured.

Warning: It is recommended that the ﬁ lter holder 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 ﬁ lter holder 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.

Cup warming plate and 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

Keeping the steam wand clean is essential to ensure the maximum

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

will decrease its steaming and frothing capacity.

Important: Wipe the wand clean with a damp cloth and rinse with a little

steam after each use.

Should milk have dried on the steam wand, wrap the wand with a clean

damp cloth, place the wand above the drip tray and turn on steam for about

10 seconds (52). Next, leave the cloth on the wand for about 5 minutes

until it soaks. If there still is dirt on the wand, repeat the procedure.

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

may damage the wand.

In the event that the steam wand is still blocked, a black cleaning pin is

provided with the espresso machine. It is placed on the base under the

water tank (49) (53).

Insert the cleaning pin in the outlet at the bottom of the wand (54). If the

steam wand is still blocked, unscrew the end of the steam wand. Clean the

wand again using the black cleaning pin and then rinse it under running

water.

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.

Warning: Descale your coffee maker at least every 3 months. The

damages which are caused by failure to descale the appliance are not

subject to warranty repairs.

Descaling solutions

Traditionally, the following agents are used for removal of scale from coffee

makers:

Citric acid solution

●

Dissolve 2 spoonful (ca. 30 g) of citric acid in 1 l of water.

Specially designated liquids or tablets.

●

Notice: For liquids and tablets, follow the instructions shown on the

packaging of these products.

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.

2. If the ﬁ lter holder is in the brew head unit, take it out, rinse thoroughly

under running water and put it aside.

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

holder unit.

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

aside in a safe place.

Important: Be careful not to lose the ﬁ 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 sufﬁ ciently big container under the brew head unit.

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

the espresso machine by pressing the POWER button.

Warning: Remember that if the illumination around the POWER button

ﬂ 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 illumination of the POWER button

will stop ﬂ ashing and will give continuous light. At the same time, the

outer edges of each of the MANUAL, the single espresso

and the

double espresso buttons will light up (continuous light).

8. Press the MANUAL button and allow half of the decaling solution to

ﬂ ow through the brew head unit.

Important: Due to the activation of the safety system (limitation to

250 ml), the user must press the MANUAL button several times to

empty half of the solution from the tank.

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

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

9. After about half of the solution has ﬂ owed through, press the MANUAL

to stop the ﬂ ow of the solution.

10. Turn the regulator knob to position

and allow the solution to run

through the steam wand for about 2 minutes.

11. Stop the appliance after 2 minutes by pressing the POWER button.

12. Next set the regulator knob into position 0.

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

descaling agent to work.

14. Next press the POWER button. The espresso machine will be switched

on.

15. Press the MANUAL button and allow the next portion of the descaling

solution to ﬂ ow through the brew head unit.

Warning: Always remember about the safety system.

16. Press the MANUAL button again to stop the ﬂ ow of the solution.

17. Turn the regulator knob to position

and allow the solution to ﬂ ow

through the steam wand for about 3-4 minutes.

18. After this time, set the regulator knob in position 0.

19. To ﬁ nish the whole descaling process, press the MANUAL button again

so that the last portion of the solution can ﬂ ow through the brew head

unit.

Warning: Always remember about the safety system.

20. Take out and empty the containers placed below the brew head and the

steam wand. When they have been emptied, replace them under the

brew head and the steam wand.

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

running water. Check that all traces of the descaling solution have been

removed. Fill up the tank with fresh water and place it in the espresso

machine (1) 2) (3) (4) (5).

22. Following the same procedure as with the descaling process, run 2 full

tanks of clean water through the brew head and the steam wand.

Warning: Always remember about the safety system.

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

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

23. When the process has ﬁ nished, remove the container from under the

brew head and wipe the whole brew head unit thoroughly.

24. Carefully install the rubber seal, the ﬁ lter, and the washer in the brew

head, following their disassembling procedure in reverse order. Using

a screwdriver, tighten the fastening screw home.

25. Fill the tank up with fresh water and replace it in the espresso machine.

The appliance is ready for further use.
