What it is

The Biasi DHW flow switch, part number KI1042107, is a reed-type switch used in Biasi gas boilers to detect domestic hot water demand. When a hot water tap is opened, the switch signals the boiler to run in DHW mode. This version is specified for appliances built up to April 2011.

Signs this part needs replacing

  • No hot water production when a hot water tap is opened
  • Boiler fails to fire in DHW mode but runs normally in heating mode
  • DHW demand is not registered, so the boiler does not respond to the tap
  • Intermittent hot water, with the boiler cutting in and out during draw-off
  • DHW operation that has become unreliable and cannot be traced to other controls

Before you order

  • Confirm your appliance model against the fit list above
  • Check the appliance build date falls up to April 2011, as later builds may use a different switch
  • Compare the part number on the existing switch with KI1042107
  • Confirm the fault lies with the switch rather than the DHW flow assembly or diaphragm
