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.

Can I reset my Beretta boiler myself when it shows an error code?

Yes, you can reset your Beretta boiler by repositioning the function selector or pressing the reset button on the control panel, depending on your model. Before resetting, address any obvious issues such as low pressure. Important: If you smell gas at any time, do not operate any switches or the boiler. Open windows, leave the property immediately, and contact a Gas Safe registered engineer from outside.

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.

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