What does error code 31 mean on Beretta Meteo Green boilers?

Error code 31 indicates a smoke exhaust pressure switch fault (on MIX CSI models) - the air pressure switch has failed or detected incorrect pressure. Check the flue for blockages and reset. If error 31 persists, contact a qualified heating engineer.

What does error code A03 mean on Beretta Ciao boilers?

Error code A03 indicates a fan alarm - the boiler has detected a fault with the fan or air pressure switch. Ensure all flue terminals are clear of obstructions and reset the boiler. If the alarm persists, contact a qualified heating engineer.

What does error code E070 mean on Beretta Exclusive boilers?

Error code E070 indicates a flow sensor fault or overtemperature - the sensor has failed or flow temperature is excessive. Check radiators are open, allow the system to cool, and reset. If E070 returns, contact a qualified heating engineer.

What does error code E030 mean on Beretta Exclusive boilers?

Error code E030 indicates a fan fault - the combustion fan has failed to operate correctly. Check the flue is not blocked and reset the boiler. If the fan is silent or making unusual noises, contact a qualified heating engineer immediately.

What does error code E085 mean on Beretta Exclusive Green boilers?

Error code E085 indicates an incomplete combustion fault. Do not attempt multiple resets. Contact a Gas Safe registered engineer to inspect the burner, flue system, and combustion chamber.

When does my Beretta boiler heating system need a power flush?

Signs your system may need a power flush include cold spots on radiators (especially at the bottom), slow heating, discoloured water when bleeding radiators, frequent boiler breakdowns, or unusual noises. A power flush removes sludge and magnetite buildup that reduces efficiency. It is often recommended when installing a new boiler and as preventive maintenance every 5-10 years. A qualified heating engineer can assess whether your system would benefit from this treatment.

What should I do if my Beretta boiler won't ignite?

If your Beretta boiler won't ignite, first check that the gas supply is on and other gas appliances are working. Verify the boiler has adequate pressure (1.0-1.5 bar) and that the thermostat is calling for heat. Try resetting the boiler using the reset button. If the boiler still won't ignite, displays an error code, or you suspect a gas supply issue, do not attempt further troubleshooting. Contact a Gas Safe registered engineer to diagnose and repair the fault safely.

Why are my radiators cold when my Beretta boiler is running?

Common causes include trapped air in radiators, low boiler pressure, stuck thermostatic radiator valves (TRVs), a faulty circulation pump, or sludge buildup in the system. Check the boiler pressure first, then try bleeding radiators to release trapped air using a radiator key with a cloth to catch any water drips. Check and top up the boiler pressure afterwards if needed.

What is the difference between a combi and system boiler?

A combi (combination) boiler heats water directly from the mains on demand, providing instant hot water without needing a storage cylinder or cold water tank. A system boiler works with a separate hot water cylinder to store heated water, making it suitable for homes with higher hot water demand or multiple bathrooms. Combi boilers are more compact and suit smaller properties, while system boilers can supply hot water to multiple outlets simultaneously.

What does maintenance reminder code 91 mean on my Beretta boiler?

Code 91 is a maintenance alert that signals the need for servicing or cleaning of the primary heat exchanger. It appears based on hours accumulated in particular operating conditions, determined by the boiler's self-diagnosis system.
