BoilerFaultCodesTechnical description
Low voltage (less than 195v)
What causes this fault?
This fault occurs when the electrical supply entering the boiler drops below a safe working level, meaning the internal components cannot get the steady power they need to operate. The most common reasons are a general brownout in your local area, a failing mains power cable, or a fault within the boiler's own control board that prevents it from processing electricity correctly.
This fault can be more common during peak winter months or heatwaves when the national grid is under heavy strain, leading to localized drops in voltage.
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.
