What it is

The Worcester Bosch 87161409210 is a fibre washer measuring 15.0 x 10.0 x 1.0 mm, supplied as a service spare for Worcester Bosch domestic heating appliances. It belongs to the gaskets, seals and washers group of parts and forms a compression seal at the joint where it is fitted, helping the appliance hold pressure and run without water loss at that connection. It is used across the Worcester Junior RSF and Danesmoor families, among other models.

Signs this part needs replacing

  • Water weeping or a visible drip at the joint the washer seals
  • Staining, crusting or limescale tracking around the fitting
  • The washer feels hard, flattened or brittle once the joint is opened
  • Repeated pressure loss, or the appliance needing topping up more often than usual
  • A joint that will not seal cleanly after being re-made
