Anti-limescale Function
The formation of limescale (calcium carbonate) inside the appliance (in particular on the heating elements) is
linked to the characteristics of the water which may be more or less rich in calcium. It may cause increased noise
in the heating phases and change the sensitivity of the sensors making the control performed by the electronic
control unit more difficult. To decrease this phenomenon first check that the appliance installation conditions are
those recommended (see paragraph "Hydraulic Connections"). The latter is therefore equipped with an "anti-
limescale function": it is an automatic protection of the appliance to prevent excessive heating cycles caused by
limestone on the heating element. Once the anti-limescale function starts to work, the temperature is lowered to 60
°C (if the temperature set was higher). If the anti-limescale function is activated, the ECO EVO function is disabled.
• For models equipped with a user interface type shown in figure 8: the active status of the function is
shown by flashing LEDs 1, 2 and 3.
• For models equipped with a user interface type shown in figure 9: the active status of the function is
shown on the display with E70 and "remaining time" that alternate every 3 seconds.
The anti-limescale function cannot be disabled by the user, the product automatically resets the status once
the problem is resolved (see paragraph "Scheduled maintenance").

USEFUL INFORMATION

If the water comes out cold, have the following checked:
- the presence of voltage on the power terminal block (M Fig. 7);
- the circuit board;
- the heating parts of the heating element;
- inspect the bypass pipe (X Fig. 7);
- the sensor holder rods (K Fig. 7).
If the water comes out boiling hot (steam in the taps)
Disconnect the appliance from the electricity supply and have the following checked:
- the circuit board;
- the amount of scale on the boiler and components;
- the sensor holder rods (K Fig. 7).
If the hot water delivery is insufficient:
Have the following checked:
- the pressure of the water mains;
- the condition of the deflector on the cold water intake pipe;
- the condition of the hot water pipe;
- the electrical components.
Water trickling from the pressure safety device
During the heating phase, some water may trickle from the tap. This is normal. To prevent the water trick-
ling, a suitable expansion vessel must be installed on the flow system. If the trickling continues even after
the heating phase, have the following checked:
- device calibration;
- the pressure of the water mains.
Caution: Never obstruct the appliance outlet!
NEVER ATTEMPT TO REPAIR THE APPLIANCE YOURSELF - ALWAYS HAVE THIS
DONE BY A QUALIFIED TECHNICIAN.
The indicated data and specifications are not binding; the manufacturer reserves the right to mod-

This product is in conformity with REACH regulations.
This product conforms to Directive WEEE 2012/19/EU.
The symbol of the crossed waste paper basket on the appliance and its packaging indicates that the product
must be scrapped separately from other waste at the end of its service life. The user must therefore hand the
equipment over to a sorted waste disposal facility for electro-technical and electronic equipment at the end of its
service life.
Alternatively, he may return the equipment to the retailer at the time of purchase of a new equivalent type of ap-
pliance. Electronic equipment of size less than 25 cm can be handed over to any electronics equipment retailer
whose sales area is at least 400 m
