LED Ref. 2, 3, 4 and 5 - overheating caused by lack of water - boiler inlet
Exit the diagnostic function by pressing the ON/OFF button (Ref. A) or wait for 25 seconds.
• For models equipped with a user interface type shown in figure 9.
When any of the operation problems occur, the appliance goes into "fault status" and the corresponding error
code flashes on the display (for example, E01). The error codes are the following:
E01 - internal error of the board
E04 - impressed current anode malfunction (corrosion protection is not guaranteed)
E09 - excessive number of resets in fifteen minutes
E10 - broken temperature probes (open or short circuited) - boiler outlet
E11 - excessive water temperature detected by single sensor - boiler outlet
E12 - general excessive water temperature (circuit board fault) - boiler outlet
E14 - Failure to heat water with powered heating element - boiler outlet
E15 - overheating caused by lack of water - boiler outlet
E20 - broken temperature probes (open or short circuited) - boiler inlet
E21 - excessive water temperature detected by single sensor - boiler inlet
E22 - general excessive water temperature (circuit board fault) - boiler inlet
E24 - failure to heat water with powered heating element - boiler inlet
E25 - overheating caused by lack of water - boiler inlet
E61 - internal malfunction of the circuit board (NFC communication)
E62 - internal malfunction of the circuit board (NFC data damaged)
E70 - Limescale detected - Limited mode on
Error reset: reset the appliance by switching it off and on from the ON/OFF button (Ref. A). If the cause of
the malfunction disappears immediately when reset, the appliance resumes its regular operation. On the
contrary, if the error code continues to appear on the display: contact the Technical Service Centre.

Additional Functions

Time remaining
For models equipped with user interface type shown in figure 9. The time remaining to reach the tem-
perature set by the user (Ref. E) is shown in the centre of the display (Ref. F).
The value is indicative and is an estimate of the "time remaining" parameter. The value is automatically
updated during the heating phase.
Anti-freeze function
The anti-freeze function is the appliances automatic protection to avoid damages caused by very low tempe-
ratures below 5 °C, in the event in which the product is turned off during winter. It is recommended that the
product remains plugged in to the mains power, even if it is inactive for a long time.
• For models equipped with user interface type shown in figure 8: the function is enabled, but not re-
commended if activated.
• For models equipped with a user interface type shown in figure 9: the function is enabled; activation
is displayed on the display with "AF" .
For all models, once the temperature rises to a safer level such as to avoid damage from ice and frost, the
water heating is switched off again.
Activating the "thermal disinfection cycle" (anti-legionella)
The anti-legionella function (disabled by default) consists of a water heating cycle at 65 °C which carries out
a thermal disinfection action against the bacteria in question.
If enabled, the appliance performs a heating cycle at 60 °C for 1 hour, every day. When the product is off,
the anti-legionella function is not active. If the appliance is switched off during the anti-legionella cycle, the
product turns off and the function is not completed. If the product is turned on again, the anti-legionella fun-
ction is reactivated. At the end of each cycle, the operating temperature returns to the value set previously
by the user.
• For models equipped with user interface type shown in figure 8: the activation of the anti-legionella
cycle appears as a normal temperature adjustment 60 °C. Activate this function by pressing and holding both
the "ECO" and "+" buttons for 4 s.; once activation is confirmed, LED 60°C (Rif. 3) will flash quickly for 4 s.
Permanently deactivate the function by repeating the above steps; once the deactivation is confirmed, LED
40°C (Rif. 1) will flash quickly for 4 s.
• For models equipped with a user interface type shown in figure 9: during the "thermal disinfection
cycle" , the display alternately shows the water temperature and "-AB-" . To activate/deactivate the function,
with the working product, hold the "mode" button for 3 s. Set "Ab 1" (to activate the function) or "Ab 0" (to disa-
ble the function) using the knob and confirm by pressing the "set" button. To confirm activation/deactivation,
the product returns to normal operation status.
