What it is

The pressure switch disk is a component used in the pressure sensing circuit of Biasi central heating boilers. It forms part of the pressure switch assembly, where it responds to changes in system pressure to signal the boiler's control sequence. This part is identified by the manufacturer's code BI1011111.

Signs this part needs replacing

  • Boiler fails to fire or locks out when there is adequate system pressure
  • Boiler does not respond to changes in system pressure
  • Intermittent operation or nuisance lockouts during heating demand
  • Fault code or diagnostic indication relating to the pressure switch circuit
  • Visible damage, distortion or contamination of the disk

Before you order

  • Confirm your appliance model against the fitment list above
  • Check the existing pressure switch assembly and disk for damage or debris
  • Verify the superseded code on your existing component where visible
  • Confirm the boiler is isolated and depressurised before any work begins
