What it is

The Worcester Bosch 87101031540 is a washer set manufactured by Worcester Bosch for use in the Greenstar family of gas boilers. It forms part of the gaskets, o-rings, seals and washers group of service items, sealing the joint where components meet so the appliance continues to run without weeping or pressure loss. The set is typically used when parts are removed and refitted during repair or routine maintenance, restoring the seal at the connection.

Signs this part needs replacing

  • Weeping or visible water at a joint sealed by the washer
  • Damp staining, scale or mineral deposits around the sealing face
  • A washer that has hardened, flattened or cracked with age and heat cycling
  • Repeated pressure loss traced back to a sealed connection
  • Slight seepage after a component has been disturbed and refitted
