Technical description

Setting failure

What causes this fault?

This fault occurs when the boiler's internal memory becomes corrupted or disconnected, causing it to lose the vital instructions needed to run safely. The most common reason is a failure of the main control board or a loose connection with the parameter plug, which acts like a small memory stick containing the unit's identity.

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.
