What does error code E02 mean on Beretta Power Plus commercial boilers?

Error code E02 on Beretta Power Plus commercial boilers indicates NTC-1 is open - the sensor at the output of the device is not connected or has an open circuit. Contact a qualified heating engineer to inspect and replace the temperature sensor.

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 E051 mean on Beretta Exclusive Green boilers?

Error code E051 indicates a control error or fan status fault - the electronic control board has detected a fan operation anomaly. Reset the boiler. If E051 returns, contact a qualified heating engineer to inspect the fan and control board.

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 code 91 mean on Beretta Exclusive boilers?

Code 91 is a maintenance reminder indicating the service interval has been reached. Schedule an annual service with a qualified heating engineer for heat exchanger cleaning, safety checks, and service counter reset.

What is included in a Beretta boiler annual service?

A Gas Safe registered engineer will perform visual checks for leaks and corrosion, test gas pressure and combustion efficiency, clean the burner and heat exchanger, check the expansion vessel and pressure relief valve, verify the flue is fitted correctly, and ensure the boiler is using the correct amount of gas without emitting carbon monoxide.

How do I clean and maintain my Beretta boiler?

You can clean the external casing periodically with soapy water using a soft cloth. However, any internal cleaning or technical maintenance must only be carried out by a qualified heating engineer during the annual service.

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.

Why is my Beretta boiler making a kettling noise?

A kettling noise (similar to a boiling kettle) usually indicates limescale or sludge buildup restricting water flow through the heat exchanger. This causes water to overheat and create steam, producing the rumbling or whistling sound. Kettling reduces boiler efficiency and can cause damage over time. Contact a qualified heating engineer to inspect the system, as a chemical clean or power flush may be required to resolve the issue.
