1.5. Boiler shutdown
The boiler shuts down automatically if a malfunction occurs.
Refer to Tables 1 and 2 to identify the boiler operating mode.
Refer to Table 2 and section 6 to identify possible causes of the shutdown. The troubleshooting section is at the end of this manual.
Below is a list of kinds of shutdown and the procedure to follow in each.
1.5.1. Burner shutdown
If the burner shuts down as there is no flame, the burner shutdown symbol is displayed and code E01 flashes.
If this happens, proceed as follows:
• check that the gas cock is open and light a gas ring for example to check the gas supply;
• if the gas supply is normal, turn selector 2 to the reset position
for 2 seconds, then back to the desired position. If after three attempts
the burner still fails to ignite, contact a qualified Service Centre or service engineer.
If the burner shuts down frequently, there is a recurring malfunction, so contact an Authorised Service Centre or a qualified service
engineer.
1.5.2. Shutdown due to overheating
If the water temperature is too high, the boiler will shut down. The burner shutdown symbol is displayed and code E02 flashes. Contact
a qualified Service Centre or service engineer.
1.5.3. Shutdown due to air/flue gas system malfunction
If the air/flue gas system malfunctions, the boiler shuts down. The burner shutdown symbol symbol is displayed and code E20
(differential pressure switch cut-in) flashes.
Contact a qualified Service Centre or service engineer.
1.5.4. Shutdown due to low fluid level
If water circulation in the DHW circuit is incorrect, the boiler shuts down.
The LCD displays the boiler shutdown
symbol and the E10 or E26 codes flashing, depending on the type of malfunction.
In the former case (code E10 flashing), there may be 2 possible reasons:
a) The pressure gauge (5 in fig. 1) shows a pressure value below 1 bar
Fill the system with water as detailed below:
• Turn the filling tap (fig. 5) anticlockwise to allow water to enter the boiler;
• Keep the tap open until the pressure gauge shows a value of 1÷1.3 bar;
• Turn the tap fully clockwise to close it;
• Turn selector 2 to the RESET position
for a few seconds, then back to the desired position.
If the boiler still fails to operate, contact a qualified Service Centre or service engineer.
Make sure you close the tap carefully after filling.
If you do not, when the pressure increases, the safety valve may activate and discharge water.
b) The pressure gauge (5 in fig. 1) shows a pressure value of 1÷1.3 bar
Contact an Authorised Service Centre or a qualified service engineer.
In the latter case (code E26 flashing) contact a qualified Service Centre or service engineer.
