Boiler fault codes are provided for general information only and should not replace the manufacturer's instructions or professional diagnosis. Boilers contain gas, electrical and combustion components. Internal repairs and testing should only be carried out by a suitably qualified engineer. Where gas work is required in the UK, use a Gas Safe registered engineer.
