What it is
The Biasi BI2535101 is the main electronic control printed circuit board with integrated ignition control, used across the Biasi Advance OV range of open vent boilers. It manages boiler sequencing and provides the ignition function that lights the burner on demand. The board is fitted inside the appliance casing and connects to the boiler's wiring harness, sensors and gas valve circuit.
Signs this part needs replacing
- The boiler fails to ignite, with no spark at the burner despite a call for heat
- The appliance locks out repeatedly and will not reset reliably
- The boiler shows no response to demand, with the fan or pump not sequencing as expected
- Intermittent operation, cutting out mid-cycle or failing to complete a start sequence
- Visible damage to the board, such as burning, scorching or failed components
Before you order
- Confirm the boiler model and GC number from the appliance data badge against the fit list above
- Check whether the appliance is natural gas or LPG, as the correct board must match the boiler variant
- Compare the part number printed on the existing board with BI2535101 before ordering
- Isolate the electrical supply to the boiler before removing or fitting any control board
