What it is

The Worcester Bosch 87186469710 is a filter cartridge rated at 12 L/min, supplied for the Greenstar 2000 Combi appliance family. It is listed as a sanitary cartridge within the diverter valve assembly, where it forms part of the domestic hot water circuit on the Gr2300IW 30 C models.

Signs this part needs replacing

  • Domestic hot water temperature fluctuating or running cold at the outlet
  • No hot water response when a tap is opened
  • Boiler failing to switch cleanly between central heating and hot water
  • Visible scale, debris or damage on the cartridge when removed

Before you order

  • Check the model and GC number on the appliance data plate against the fitments listed
  • Confirm the existing cartridge is marked with part number 87186469710
  • Verify the 12 L/min flow rating matches the cartridge being removed
  • Isolate the water and electrical supplies before dismantling the diverter valve assembly
