What it is

The Vaillant 0020133816 is an electrode used in Vaillant ecoTEC Plus VU and VUW gas boilers. It forms part of the ignition and flame sensing circuit, providing the spark at the burner and feeding the flame signal back to the boiler's control board. It is listed under electrodes within gas boiler spares.

Signs this part needs replacing

  • Boiler fails to ignite and locks out on an ignition fault
  • No spark at the burner when the boiler is called for heat
  • Repeated lockouts that clear after a reset, then return
  • Visible erosion, pitting or contamination of the electrode tip
  • Cracked or discoloured ceramic insulator on the electrode

Before you order

  • Confirm your boiler model and, where shown, its GC number against the fitment list above
  • Check the revision suffix (R1, R2, R4, R6 and similar), as fitment varies between revisions
  • Inspect the existing electrode and its lead for damage before ordering
  • Confirm the electrode position required on your appliance, as ignition and sensing electrodes are not interchangeable
