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 possible causes of the shutdown and the procedure to follow in each case.
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 kitchen gas ring for example to check the gas supply;
• if the gas supply is normal, turn selector 2 to the reset position
for a few seconds, then back to
the desired position. If after three attempts the burner still fails to ignite, contact an Authorised Service
Centre or a qualified 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 an Authorised Service Centre or a qualified 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 is displayed and code E03 (flue gas
thermostat) flashes.
Contact an Authorised Service Centre or a qualified service engineer.
1.5.4. Shutdown due to a water circulation malfunction
If the pressure or water circulation in the heating system are incorrect, the boiler shuts down. The boiler shutdown symbol is displa-
yed and code E10 or E26 flashes, according to the malfunction.
With code E10 flashing there can be two different situations:
a) the pressure gauge (5, Fig. 1) shows a pressure lower than 1 bar
Proceed as follows to restore the correct water pressure:
• 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 clockwise to close it.
• Wait a minute until the malfunction disappears from the display.
If the boiler still fails to operate, contact an Authorised Service Centre or a qualified 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, Fig. 1) shows a pressure of 1-1.3 bar
Contact an Authorised Service Centre or a qualified service engineer.
2. With flashing code E26 , contact an Authorised Service Centre or a qualified service engineer.
