What it is

The BI1805101 is an electronic control printed circuit board with ignition function, manufactured by Biasi for its gas boiler range. It manages ignition sequencing and burner control within the appliance's electronic control circuit. It is supplied as a board assembly for service replacement.

Signs this part needs replacing

  • The boiler fails to ignite, with no spark at the electrode during a call for heat.
  • The appliance locks out repeatedly on start-up or shortly after firing.
  • Ignition is intermittent, with the boiler firing on some attempts and not others.
  • The board shows visible damage, such as scorching, burnt tracks or failed components.
  • Fault codes relating to ignition or control board function are displayed.

Before you order

  • Confirm the boiler model and GC number from the appliance data badge against the fit list above.
  • Check the part number printed on the existing board matches BI1805101 before ordering.
  • Verify the fault lies with the ignition PCB rather than the ignition electrode, lead or gas supply.
  • Work on gas appliances must be carried out by a competent, registered engineer.
