What it is

The Vaillant 0010045247 maintenance kit contains the flange gasket used on Ecotec Sustain VUW combi boilers. It seals the flange joint on the appliance, preventing water loss from the heating circuit at that connection. The kit is supplied by Vaillant as a service part for the Ecotec Sustain range.

Signs this part needs replacing

  • Water weeping or a visible drip at the flange joint
  • Staining, scale or corrosion marks around the flange face
  • Gasket hardened, flattened or cracked when the joint is opened
  • Repeated small pressure loss on the heating circuit traced to the flange
  • Gasket deformed or damaged during previous service work

Before you order

  • Confirm your appliance model against the fit list above
  • Check the GC number on the boiler data badge matches your model variant
  • Verify the part number 0010045247 against the manufacturer's parts list for your appliance
  • Confirm whether the flange joint is the source of the leak before ordering
