What it is

The Worcester Bosch 87161461600 is a turbine flow switch assembly supplied with its wiring harness. It is used on Worcester Bosch 28i RSF and HighFlow 400 Electronic appliances, where it sits in the domestic hot water circuit and detects the movement of water when a tap or outlet is opened. The turbine rotates with the flow, and the switch signal tells the boiler control board that hot water is being drawn so the burner can fire.

Signs this part needs replacing

  • No hot water, or hot water only produced when the boiler is already running for heating
  • Boiler does not fire when a hot water outlet is opened
  • Hot water temperature fluctuates or runs intermittently
  • Flow switch or hot water demand fault code shown on the appliance
  • Turbine sticking, seized or obstructed by scale and debris in the water circuit

Before you order

  • Check the GC number on the appliance data badge against the compatibility list above before ordering.
  • Confirm the appliance model and serial number, as this assembly is used across several HighFlow 400 Electronic variants.
  • This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
