What it is

The Vaillant 0020233881 is a fan assembly used in Vaillant combination boiler appliances. It provides the forced draught that draws combustion air in and pushes flue products out through the flue system. It is listed for the VUW 436/5-7 and the Ecotec Exclusive 843 VUW 436/5-7.

Signs this part needs replacing

  • The boiler locks out or fails to ignite, with a fan-related fault code logged.
  • The fan runs noisily, with rumbling, scraping or bearing whine from the fan housing.
  • The fan does not spin up when the boiler calls for heat, or spins intermittently.
  • Flue gas readings or combustion analysis fall outside the expected range.
  • Visible damage, contamination or stiffness when the fan impeller is turned by hand.

Before you order

  • Confirm the appliance model and GC number against the data badge before ordering.
  • Check the fault code and confirm the fan is the failed component, not the PCB, APS or wiring.
  • Inspect the flue and air intake paths for blockages or debris that may have caused the failure.
  • Check the fan mounting gasket and sealing arrangement for condition, as these are not supplied with the fan unless stated.
