What causes this fault?

This fault occurs when the data stored on the boiler's internal memory chip becomes corrupted or unreadable. The most common reason is a power surge or a gradual component failure on the main circuit board, which effectively causes the boiler to 'forget' its critical safety and operating instructions.

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.
