What it is

The Biasi BI1305101 is a full sequence control printed circuit board supplied as a spare for Biasi water heating appliances. It runs the appliance through its start-up sequence, taking the demand signal and stepping through ignition, flame proving and burner operation. The board also manages safety lockout when the sequence does not complete within its permitted time.

Because it controls the order in which the appliance's components are energised, a fault here typically shows as a failure to light, a lockout, or a start-up that stalls partway through. The board is a plug-in style spare and is listed under Biasi's printed circuit board range.

Signs this part needs replacing

  • The appliance fails to ignite, or the start-up sequence stalls before the burner fires
  • Repeated lockouts with no progression through the fault sequence
  • The fan or pump runs on demand but the burner never lights
  • No response at all to a call for heat
  • Intermittent operation that clears briefly after a power cycle and then returns

Before you order

  • Match the number printed on the existing board against BIASIBI1305101
  • Note the appliance model and serial number from the data plate
  • Isolate the electrical supply before removing the old board
  • Photograph the wiring connections and plug positions before removal to aid refitting
