What it is

The Worcester Bosch fan washer, part 87290001830, is a sealing component used across the CDi, Greenstar, RD Series and Greenstar ErP boiler families. It sits at the joints where sections such as heat exchangers and gas valves meet the pipework, holding the connection tight against gas and water escape. Washers, O-rings and gaskets of this type are used in a number of places through the appliance wherever a section joins a pipe.

Signs this part needs replacing

  • Water weeping or a damp trace around a pipe connection at the heat exchanger or gas valve
  • A gas smell or a detected leak at a joint sealed by this washer
  • The washer has hardened, flattened or cracked through repeated heat cycling
  • Repeated system pressure loss with no other obvious cause
  • Visible deformation or discolouration found when the joint is opened for service

Before you order

  • Check the GC number and the appliance serial plate to confirm this washer suits your model
  • Confirm the previous numbers 87110041460 and RA816160 if ordering against an older parts list
  • Consider whether a full gasket and seal kit is needed where several joints are being disturbed at once
  • This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
