What it is

The Worcester Bosch 87161087220 is a diverter valve body assembly used in Worcester Bosch Greenstar Heatslave appliances. It forms the hydraulic body of the diverter valve, the component that directs water flow between the domestic hot water and heating circuits as the appliance switches duty. It is a Worcester Bosch spare, listed under diverter valves and hydraulics.

Signs this part needs replacing

  • Domestic hot water runs lukewarm or cold while the heating circuit stays hot
  • Radiators warm up when only hot water is called for, or hot water is produced when only heating is demanded
  • The diverter valve motor runs but the valve body does not change position
  • Water weeping from the valve body or from the spindle area
  • The appliance locks out or reports a fault after failing to reach the correct flow path

Before you order

  • Confirm the appliance model and serial number against the compatibility list before ordering, as the same part number is used across several Heatslave variants
  • Check the existing valve body for the part number 87161087220 or the alternative number 1015427
  • Inspect the seals and gaskets on the valve body and order replacements if they are worn or hardened
