7. WATER HARDNESS

7.1 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.

Water Hardness Test Procedure:

  1. Remove the "TOTAL HARDNESS TEST" indicator paper (C5) from its pack. Diagram shows removing test paper from packaging.
  2. Immerse the paper completely in a glass of water for one second. Diagram shows immersing test paper in water.
  3. Remove the paper from the water and shake lightly. Diagram shows removing and shaking the test paper.
  4. Set the appliance as indicated in section "3. Menu 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.

Total Hardness Test result Button Level
[Color blocks indicating 1 red square] [Temperature icon MIN] 1 soft water
[Color blocks indicating 2 red squares] [Temperature icon MED] 2 medium water
[Color blocks indicating 3 red squares] [Temperature icon MAX] 3 hard or very hard water

8. CLEANING THE STEAM NOZZLE

Steps:

  1. After every use, remove with a soft damp cloth any milk residues from the steam wand (A9) and the nozzle. Diagram shows wiping the steam wand and nozzle with a cloth.
  2. Use the steam for a deeper cleaning. Diagram shows steam emitting from the nozzle for cleaning.
  3. To maintain the better usability of the nozzle, when clogged, use the Cleaning Tool (C10) for opening the hole. Diagram shows using the cleaning tool C10 on the steam nozzle.

9. DESCALING

Time: 40 Minutes

Descaler: EcoDecalk (2 L capacity recommended)

Please note:

Descaling Procedure:

When the descale light (B3) comes on, it is time to proceed descaling the machine. The descaling cycle can be run at 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). Diagram shows pouring descaler into the water tank.
  2. Add water (1 liter) up to the level B. Then put the water tank back in the appliance. Diagram shows adding water to the tank and placing it back.
  3. Turn the mode selector dial (B8) to the descaling position [⚙️]. The OK light (B6) turns to orange and the descaling light (B3) flashes. Diagram shows turning the dial to the descaling symbol.

  2. Keep pressed for at least 3 seconds the OK button [B6]: the OK light begins to flash; descaling starts. Diagram shows pressing the OK button.

The descale programme starts and the descaler liquid comes out of the steam wand and coffee outlet.

Delivery stops and the OK light turns to white. This indicates that it is necessary to proceed with rinsing: see next page.

Descaling (Rinsing Procedure):

  1. Empty the recipient used to collect the descaler solution and replace it empty. Diagram shows emptying the collection container.
  2. 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. Diagram shows rinsing the water tank and refilling it.
  3. Position a recipient under the coffee outlet, hot water spout and steam wand. Diagram shows positioning a container under the dispensing spouts for rinsing.
  4. Press the OK button [B6]: rinsing starts. Diagram shows pressing the OK button to start rinsing.
  5. When rinsing is complete, delivery stops and the appliance prepares to be used again. Diagram shows the machine after rinsing.

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, vacuum 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 in the machine. 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.

  • 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. Menu settings"- "Extra grinding adjustment").
You are using the 2 cup filter (C4). Make sure the 2X light is on.
