What it is

The Worcester Bosch 87161156820 is a 1 inch washer from the manufacturer's gaskets, seals and washers range. It sits at a connection point inside the appliance and forms the sealing face that keeps that joint tight during normal operation. It is a service item rather than a control component, so it is replaced when the joint it serves starts to weep or when the washer is disturbed during other repair work.

Signs this part needs replacing

  • Weeping or dripping at the joint the washer seals
  • Water staining, corrosion or mineral scale around the connection
  • The washer looks flattened, hardened, cracked or deformed once removed
  • Repeated pressure loss traced back to a joint rather than to the boiler itself
  • A slight seep after the joint has been opened and reassembled during other work

Before you order

  • Check the GC number and appliance serial number against the compatibility list before ordering, as the same part number can be listed against several model variants.
  • The alternative number 1022062 may appear on older documentation for this item.
  • This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
