Frequently Asked Questions - Brava One BF SIME
How to turn on the Brava One BF boiler?
Make sure gas and power supply are on. Press the on/off button. The green light turns on. The boiler automatically goes to standby. For hot water, open a tap; for heating, adjust the room thermostat.
What to do if the boiler does not turn on?
Check gas supply (meter open) and power supply (circuit breaker). Check water pressure (between 1 and 2 bar). If the problem persists, contact a professional.
How to bleed air from radiators?
Place a container under the radiator bleed screw. Turn the screw with a key until you hear a hissing sound. When water comes out, close it. Check the boiler pressure after bleeding.
How often should the boiler be serviced?
Annual servicing by a qualified professional is mandatory. It includes cleaning the burner, heat exchanger, sensor, and checking safety devices.
What does the error code on the display mean?
Refer to the error code table in the manual. For example, code E01 indicates an ignition fault. If the code persists after a reset, call a technician.
How to adjust the domestic hot water temperature?
Turn the DHW adjustment knob (usually with a shower icon) to select a temperature between 30°C and 60°C. A temperature of 55°C is recommended to prevent legionella.
The boiler is making noise, is that normal?
A slight operating noise is normal. If you hear banging or whistling, it may indicate scale buildup in the heat exchanger. Descaling by a professional may be necessary.
Can I install the boiler myself?
No, installation must be carried out by a certified heating installer, in accordance with current regulations (DTU 61.1). Improper installation may void the warranty.
How to reset the maintenance indicator?
After the annual service, press the reset button (often marked 'RESET') for 5 seconds until the light goes off. Refer to the manual for the exact location.
Where to find spare parts?
Spare parts are available from SIME after-sales service or authorized dealers. Use the part reference indicated in the manual.
