BOARD ERROR

From this model's manual
Verified against the Ideal/Ideal Mexico installation & service manual.
Plain-English guidance below. Severity, DIY steps, costs and parts are our interpretation to help you act, not text from the manual.

What causes this fault?

This fault occurs when the boiler's main control board suffers a hardware failure or a corruption in its software, meaning it can no longer process commands. The most common reason is age-related wear to the electrical components on the board, though it can also be triggered by a sudden power surge or moisture getting into the control box.

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.
