What does error code 22 mean on Beretta Meteo Green boilers?

Error code 22 indicates a flue gas thermostat fault (on CAI models) - the exhaust temperature sensor has failed. Reset the boiler. If error 22 persists, contact a qualified heating engineer to inspect and replace the sensor.

What does error code E091 mean on Beretta Exclusive Green boilers?

Error code E091 indicates the primary heat exchanger requires cleaning - this is a maintenance alert based on accumulated operating hours. Schedule a service with a qualified heating engineer to clean the heat exchanger and reset the service counter.

What does error code E088 mean on Beretta Exclusive Green boilers?

Error code E088 indicates an incomplete combustion fault related to exhaust conditions. Ensure adequate ventilation and check for flue blockages. Contact a Gas Safe registered engineer for inspection.

What does error code 60 mean on Beretta Meteo Green boilers?

Error code 60 indicates a DHW (domestic hot water) temperature sensor fault - the sensor has failed or is providing incorrect readings. Reset the boiler. If error 60 persists, contact a qualified heating engineer for sensor replacement.

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.

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.

How do I switch my Beretta boiler to summer mode for hot water only?

Beretta boilers have a mode selector (often labelled Winter/Summer or with sun/snowflake symbols) on the control panel. Switch to Summer mode to deactivate central heating while keeping hot water available on demand. In this mode, the boiler remains in standby until you open a hot tap. This setting helps save energy during warmer months while maintaining hot water availability.

Why does my Beretta boiler keep losing pressure?

The most common causes of pressure loss are small leaks in the heating system (pipes, radiators, or radiator valves), a faulty expansion vessel, or a problematic pressure relief valve. Less commonly, the pressure gauge itself may be faulty. If your boiler loses pressure repeatedly, contact a qualified heating engineer to inspect the system for leaks or component issues.
