Technical description
Forced reset unit unlocked
What causes this fault?
This fault occurs when the reset button has been pressed more than five times within a one-hour period. It is a safety feature designed to prevent you from repeatedly trying to start a boiler that has a persistent internal problem. The boiler essentially stops responding to resets to protect its components from further damage.
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.
