RESET/DIAGNOSTICS
When any of the operation problems occur, the appliance goes into "fault status" and the corresponding error
code fl ashes 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 fi fteen 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 healing 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 - Limited mode
Error reset: reset the appliance by switching iioff and on from the ON/OFF buttonRif.A).
If the cause of the malfunction disappears immediately when reset, the appliance resumes its regular opera-
tion. On the contrary, if the error code continues to appear on the display: contact the Technical Service Centre.
For models equipped with the user interface shown in figure 10
When any of the operation problems occur, the appliance goes into "fault status" and all LEDs on the control
panel will fl ash simultaneously.
Diagnostics: to enable the diagnostic function, hold the ON/OFF " " button and the "-" button for 5 seconds.
The type of fault is indicated by fi ve LEDs according to the following scheme:
LED 40° - internal malfunction of the circuit board
LED 40° - 60° - internal malfunction of the circuit board (NFC communication or NFC data)
LED 60° - broken temperature probes (open or short circuited) - boiler outlet
LED 80° - excessive water temperature detected by single sensor - boiler outlet
LED 70° - 80° - generai excessive water temperature (circuit board fault) - boiler outlet
LED 60° - 70° - Failure to heat water with powered heating element - boiler outlet
LED 60°, 70° e 80° - overheating caused by lack of water - boiler outlet
LED 50° e 60° - broken temperature probes (open or short circuiteci) - boiler inlet
LED 50° e 80° - excessive water temperature detected by single sensor - boiler inlet
LED 50°, 70° e 80° - generai excessive water temperature (circuit board fault) - boiler inlet
LED Rif. 50°, 60° e 70° - failure to heat water with powered heating element - boiler inlet
LED Rif. 50°, 60°, 70° e 80° - overheating caused by lack of water - boiler inlet
Exit the diagnostic function by pressing the ON/OFF button " " or wait tor 25 seconds."
