What it is

The Biasi BI1271501 is a magnetic flow switch and filter kit used on Garda and Riva family gas boilers. It detects water flow through the heating circuit and captures magnetic debris carried in the system water. The assembly is supplied for appliances from serial number N121710705 onwards.

Signs this part needs replacing

  • Boiler fails to fire or locks out despite a call for heat or hot water
  • Intermittent operation, with the boiler cutting out during a draw-off
  • Flow switch fails to register pump circulation
  • Filter element heavily contaminated with magnetite or sludge
  • Fault code or lockout relating to water flow on the appliance display

Before you order

  • Check the model name against the fitment list for your boiler
  • Inspect the existing flow switch and filter housing for damage or debris before ordering
