1.11. Boiler blocking
In case of malfunctions, the boiler gets automatically blocked. To acknowledge the boiler operation mode refer to Table 3 and Table 4.
To acknowledge the possible causes of the malfunction check also paragraph “7. Troubleshooting” at the end of this manual.
Proceed then as described below, depending on the cause of the blocking.
1.11.1. Burner blocked
If the burner gets blocked due to the lack of flame, the flashing code
E06
is displayed on the screen. In this case, proceed as follows:
- check, by switching on a stove, for instance, if the gas valve is open and if gas is supplied;
- after having checked to make sure gas is normally supplied, unlock the burner by pressing the key “
” (
B
fig. 1): if the appliance does
not start and gets block after the third attempt, contact an Authorized Service Centre or personnel qualified for maintenance.
If the burner gets frequently blocked, meaning there is a recurring fault in its operation, contact an Authorized Service Centre or personnel
qualified for maintenance.
1.11.2. Blocking due to over-temperature
In case of over-temperature on the delivery line, the boiler gets blocked and the flashing code
E07
is displayed on the screen.
In this case please contact an Authorized Service Centre or personnel qualified for maintenance.
1.11.3. Blocking due to missing draught (fumes blocking)
In case of malfunction of the air suction and/or fumes exhaust systems, the boiler gets blocked and the flashing code
E13
or
E96
is dis-
played on the screen (the fumes probe has tripped).
In this case please contact an Authorized Service Centre or personnel qualified for maintenance.
1.11.4. Block due to low water pressure in the system
In case of flashing code error
E02
indicating the blocking due to low system pressure, fed the system by acting on the filling tap fig. 2 (for
SV models the tap is located on the cold water inlet pipe).
The error
E02
is displayed when the system pressure drops below 0.5 bar and resets automatically when the pressure of the system has
exceeded the threshold of 1.1 bar.
The pressure value in the cold boiler must be 1÷1.3 bar.
To restore the water pressure value follow the indications given below:
- pull down on the knob to lower it;
- rotate the filling valve knob (fig. 2) counter-clockwise to feed water into the boiler;
- keep the valve open until on the control panel is displayed a pressure value of 1÷1.3 bar;
- shut off the valve by rotating the knob clockwise;
- push upwards the knob to fit it back.
If the boiler gets blocked again, contact an Authorized Service Centre or personnel qualified for maintenance.
After the operation has been completed, make sure to close the safety Plexiglass door. If the valve has not
been tightly closed, the pressure could increase above 2.6 bar, and have displayed on the screen the error
E03; in this case open the safety valve of the heating system and drain out some water.
