What it is

The Worcester Bosch 87161025870 is a fan assembly used on the 35CDi II RSF range of gas boilers. It draws combustion air into the burner and drives flue gases out through the flue system, holding the correct draught across the heat exchanger. The unit is supplied as a complete fan with its motor and housing.

Signs this part needs replacing

  • Boiler locks out or fails to fire, with a fan or flue-related fault code
  • Fan runs noisily, rumbling or squealing on start-up
  • Fan does not spin when the boiler calls for heat
  • Repeated overheat trips or flame failure shortly after ignition
  • Visible damage, sooting or stiffness when the fan is turned by hand

Before you order

  • Confirm the GC number on the appliance data badge matches 47-311-58 or 47-311-59 before ordering.
  • Cross-check the part number against the markings on the existing fan.
  • This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
