CLEANING AND MAINTENANCE

Important!

• Do not use solvents, abrasive detergents or alcohol to clean the coffee machine.
• Do not use metal objects to remove encrustations or coffee deposits as they could scratch metal or plastic surfaces.
• If the appliance is not used for more than a week, before using it again, we recommend you perform a rinse cycle.

Danger!

• While cleaning, never immerse the coffee maker in water. It is an electrical appliance.
• Before cleaning the outside of the appliance, turn it off, unplug from the mains socket and allow to cool.

CLEANING THE GRINDER

1. Clean the attachment area with a brush;
2. Use the brush (C9) to clean the coffee funnel.
   

WATER HARDNESS

Water hardness

The descale light (B3) comes on after a period of time established according to water hardness. The machine can also be programmed according to the actual hardness of the water supply in the various regions, in which case descaling may be required less frequently.

1. Remove the “TOTAL HARDNESS TEST” indicator paper (C5) from its pack.
   

2. Immerse the paper completely in a glass of water for one second.
   

3. Remove the paper from the water and shake lightly.

4. Set the appliance as indicated in section “3. Menù settings”.

After about a minute, 1, 2, 3, or 4 red squares form, depending on the hardness of the water. Each square corresponds to one level.

| | 1

soft water

| | 2

medium water

| | 3
hard or
| very hard
water

CLEANING THE STEAM NOZZLE

1. After every use, remove with a soft damp cloth any milk residues from the steam wand (A9) and the nozzle.
   

2. Use the steam for a deeper cleaning.
   

3. To maintain the better usability of the nozzle, when clogged, use the Cleaning Tool (C10) for opening the hole.
   

DESCALING

When the light (B3) comes on, it is time to proceed descaling the machine. The descaling cycle can be run in any moment.

1. (IF PRESENT, REMOVE THE WATER SOFTENER DEVICE). Pour the descaler into the tank (A7) up to the level A marked inside the tank (equal to one 100ml packet).

2. Add water (1 liter) up to the level B . Then put the water tank back in the appliance.

3. Turn the mode selector dial (B8) to : the OK light (B6) turns to orange and the descaling light (B3) flashes.
   

4. Make sure the portafilter is not attached and position a recipient under the coffee outlet (A10), hot water spout (A11) and steam wand (A9).
   

5. Keep pressed for at least 3 seconds the OK button: the OK light begins to flash; descaling starts.
   
   Please note

   • In case you start the descaling cycle by mistake, you can press the OK button for 10 seconds; the rinsing cycle can not be stopped (from step 9).

6. The descale programme starts and the descaler liquid comes out of the steam wand and coffee outlet. The descale programme removes limescale deposits from inside the appliance by automatically performing a series of rinses and pauses until the tank is empty.
   Delivery stops and the OK light turns to white. This indicates that it is necessary to proceed with rinsing: see next page.

7. Empty the recipient used to collect the descaler solution and replace it empty.

8. Remove the water tank, empty any residues of descaler solution, rinse with running water and fill with fresh water up to the MAX level. Put the tank back in its housing.

9. Position a recipient under the coffee outlet, hot water spout and steam wand.
   

10. Press the OK button: rinsing starts.
    

11. When rinsing is complete, delivery stops and the appliance prepares to be used again:

12. Empty the recipients used to collect the rinse water.

13. Extract and empty the drip tray (A19), then put back in the appliance.
    

14.  Empty, rinse, then fill the water tank with fresh water and replace it.
    
    Now the appliance is ready to use.

USING THE SOFTBALLS (*SOME MODELS ONLY)

Softballs is an innovative system that extends the life of the machine, without altering the sensory properties of the water, guaranteeing consistently creamy and aromatic coffee.

1. Extract the Softballs bag from the packaging.
   

2. Rinse with tap water the Softballs bag.
   

3. Deep the bag into the water tank (A7).
   

4. Change the Softballs every 3 months.
   

TROUBLESHOOTING

Only the OK light (B6) is on to indicate that the coffee or steam circuit is empty| Press the button corresponding to the OK

light to fill the circuit

The coffee filter (C3) or (C4) is blocked| Rinse the filters under abundant running water.
Coffee grind too fine or too much coffee| Adjust coffee dose and grinding (refer to Quick Guide)
The tank (A7) has been inserted incorrectly and the valves on the bottom are not open| Press the tank down lightly to open the valves on the bottom
Scale in the water circuit| Descale as described in section “9. Descaling”
The portafilter (C1) cannot be attached to the appliance| The ground coffee has not been pressed or is too much| Repeat grinding with new settings. Reduce the powder quantity: check if the filter (single or double filter) is the same size as the selector of grinding quantity (2x (B5) selected or not)
The espresso coffee drips from the edges of the portafilter (C1) rather than the holes| The portafilter is inserted incorrectly| Attach the portafilter correctly and rotate firmly as far as it will go
The espresso boiler gasket has lost elasticity or is dirty| Have the espresso boiler gasket replaced by Customer Services
The coffee filter is clogged|

• Rinse the filters under abundant running water.
• Reduce the grinding thickness

The coffee crema is too light (delivered from the spout too fast)| The appliance settings need reviewing| Refer to Quick Guide for suggestions
The coffee crema is too dark (delivered from the spout too slowly)| The appliance settings need reviewing| Refer to Quick Guide for suggestions
At the end of descaling, the appliance requests a further rinse| During the rinse cycle, the water tank (A7) has not been filled to the MAX level| Complete the rinse cycle from point (8) of section “9. Descaling”
The appliance does not grind the coffee| There is foreign matter that cannot be ground in the coffee grinder| Turn the grinder selector (A2) to 8, vacum all the beans and particles in the beans container (A3). If the problem persists, address to Customer Service Centre.
If you want to change the type of coffee| You must remove all the beans present in the machine|

• Empty the beans container (A3) (if necessary, operate the coffee mill without beans or use a vacuum cleaner to remove any remaining beans)
• Attach the portafilter (C1) and operate the coffee mill a number of times without beans to free the grinder. Attach the portafilter to the outlet of the grinder (A13). Push the portafilter to start grinding: it stops automatically. Repeat until the filter is empty
• Place the new coffee in the beans container
• If the amount of coffee ground is not enough to reach the perfect dose, proceed setting the appliance as for the first use

After grinding, the coffee filter is empty| The coffee grinder funnel is clogged| See section “6. Cleaning the grinder”.
After grinding, the ground coffee in the filter (C3) or (C4) does not reach the “perfect dose”| The quantity of ground coffee needs adjusting| Adjust the quantity of coffee with the dial (B4). If the dial is already in the max. position, select the second range of grinding adjustment (see “3. Menù settings”- “Extra grinding adjustment”).
You are using the 2 cup filter (C4)| Make sure the 2X light is on
Over time the burrs wear down| Address to a Customer Service Centre to change burrs.
