What it is

The Biasi BI1011102 is a domestic hot water (DHW) pressure switch membrane for Biasi gas boilers. It sits within the DHW pressure switch and flexes in response to changes in water pressure to actuate the switch. This membrane is a service part for the domestic hot water circuit.

Signs this part needs replacing

  • No hot water when a tap is opened, despite the boiler being on.
  • Boiler does not fire on a domestic hot water demand.
  • Intermittent hot water delivery or fluctuating temperature.
  • DHW pressure switch fails to activate or remains stuck.
  • Water leaking from the pressure switch area.

Before you order

  • Check the boiler model and GC number against the fitment list.
  • Confirm the existing part number is BI1011102.
  • Verify the part is for the domestic hot water pressure switch, not the heating circuit.
  • Check whether the superseded code BG1011102 is relevant to your appliance.
