BoilerFaultCodesTechnical description
Low water pressure
What causes this fault?
This fault occurs when the water levels inside your heating system drop below the minimum required for the boiler to operate safely. The most common reasons for this are a leak somewhere in the pipework or radiators, or simply that air was recently bled from the system without topping the pressure back up.
This issue is frequently seen in autumn when homeowners turn their heating back on for the first time and discover the pressure has naturally dropped over the summer months.
Engineer required
This is a high severity fault. Stop using the boiler and call a Gas Safe registered engineer. Do not attempt gas-related repairs yourself.
