What it is

The Vaillant 0020231109 is a front panel gasket for Vaillant HOME System -A boilers. It seals the joint at the front panel, maintaining a tight closure between the panel and the appliance casing. The gasket is a serviceable sealing component and should be inspected whenever the front panel is removed.

Signs this part needs replacing

  • Visible cracking, splitting or perishing of the gasket material
  • Hardening or flattening that prevents the gasket seating correctly
  • Discolouration, soot staining or moisture tracking around the front panel joint
  • Gasket stuck to or torn from the panel when it is removed for servicing
  • Panel no longer sits flush or seals evenly against the casing

Before you order

  • Confirm your boiler model against the fitment list above
  • Check the existing gasket for damage before refitting the front panel
  • Verify the part number 0020231109 matches the number on the component or the manufacturer's parts list
  • Inspect the panel and mating surfaces for distortion that could affect sealing
