Worcester Bosch Flow Sensor — 8716122562

Restore reliable hot water performance and ignition on Greenstar/CDi boilers. This OEM flow sensor (turbine + Hall sensor) detects DHW flow so the boiler fires and modulates correctly. It is the latest replacement for earlier codes 87161157540 and 87161072230.

Why this part

  • OEM accuracy: Factory-calibrated sensor delivers a clean signal to the PCB for stable temperature control.
  • Complete kit: Supplied with O-rings and stainless clips (contents vary by batch).
  • Direct fit: Push-fit design—no pipework changes required.

Typical compatibility*

Used across many Greenstar CDi / CDi Classic, i, Junior, Si and British Gas–badged Greenstar models (e.g., 25–42 kW CDi Classic; Greenstar 25i/30i ErP; 24i/28i Junior; 532/537/542/i etc.). Always confirm by matching the exact part number in your boiler’s exploded diagram.

Common symptoms of failure

  • No hot water unless taps are fully open
  • Hot water temperature “hunting” or cutting out
  • DHW/flow-related fault codes despite correct gas settings

What’s in the box

  • 1 × Flow sensor assembly — Worcester 8716122562

Install & safety
