What our engineer does
We check the supply and earth at the boiler, test the PCB and replace it if it is the cause. Anything involving the gas supply, gas valve, combustion chamber, flue, fan, PCB or heat exchanger must be left to a Gas Safe registered engineer and must not be attempted by the householder.
Models this applies to: Baxi 600, Baxi 800, Baxi Duo-tec, Baxi Platinum, Baxi EcoBlue, Main Eco Compact, Potterton Promax.

Other Baxi codes
