What it is

The Worcester Bosch 87101031610 is a flat sealing washer measuring 18.3 mm internal diameter by 24.3 mm outside diameter, supplied in a pack of ten. It is a sealing component used across the Worcester Bosch and Worcester British Gas Greenstar appliance range, sitting between mating faces to prevent water loss at joints and connections. Washers of this type compress as the joint is tightened to form a watertight seal, and are a routine replacement item during servicing or repair work.

Signs this part needs replacing

  • Water weeping or dripping from the joint where the washer is seated
  • The washer looks flattened, hardened or cracked when the joint is opened
  • Scale, corrosion or debris built up around the sealing face
  • A joint that continues to seep after being re-tightened
  • Damp patches, staining or mineral deposits beneath the appliance

Before you order
