What it is

The Biasi BI2185100 is a flow switch and temperature probe cable used on Biasi RIVA Compact HE and RIVA PLUS HE gas boilers. It carries the signal between the flow switch and temperature probe and the boiler's control PCB. This variant is specified for appliances from serial number N000550710 onwards.

Signs this part needs replacing

  • Intermittent hot water delivery or the boiler failing to respond to a hot water draw-off
  • Flow switch signal not reaching the PCB, causing the boiler to stay in standby
  • Temperature probe readings that are erratic or absent at the control
  • Visible damage to the cable, such as frayed, split or heat-affected insulation
  • Loose, corroded or poorly seated connectors at either end of the cable

Before you order

  • Confirm the boiler serial number is N000550710 or later, as this cable is specified from that number onwards
  • Check the appliance model against the fit list above, including whether it is the LPG variant
  • Inspect the existing cable routing and connectors so the replacement matches the installation
  • Verify the fault is in the cable and not the flow switch or temperature probe itself
