The boiler's water pressure is too low. This is a common issue that prevents the boiler from operating safely and efficiently.
Click steps to track your progress.
Check the boiler's pressure gauge; it should typically be between 1.0 and 1.5 bar.
Follow your boiler's manual to re-pressurize the system by opening the filling loop.
If the pressure drops again quickly, check for leaks or contact a Gas Safe registered engineer.
