What it is

The Worcester Bosch 87161409200 is a washer supplied for the sealing arrangements found across Worcester Bosch central heating and hot water appliances. Washers of this type sit at joints and connections within the water circuit, where they compress to form a watertight barrier and stop drips or gradual pressure loss. It is a serviceable item, so it is normally renewed whenever a joint is opened or when an existing seal has hardened with age.

Signs this part needs replacing

  • Water weeping or a visible drip at a joint or connection on the appliance
  • Damp staining, corrosion or limescale around the sealing face
  • A washer that has hardened, flattened, cracked or perished when the joint is opened
  • Repeated pressure loss in the heating circuit traced back to a joint
  • A seal that no longer sits square or compresses properly on reassembly

Before you order

  • Check the GC number or the appliance serial plate to confirm this washer suits your model before ordering.
  • Cross-reference the alternative part number 1017627 against the item being replaced.
  • If the joint is being disturbed as part of a wider repair, check whether any other seals on the same assembly also need renewing.
  • This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
