What it is

The Vaillant 0010029270 is a control electrode used in Vaillant Ecotec Cs/1-5 (2023) appliances. It sits in the combustion circuit and provides the flame sensing signal that the boiler's control board uses to confirm the burner has lit and is burning correctly. It is a serviceable component, typically replaced when flame detection becomes unreliable.

Signs this part needs replacing

  • Boiler locks out shortly after ignition or fails to prove flame
  • Repeated flame loss faults during a demand for heat or hot water
  • Ignition occurs but the burner shuts down within seconds
  • Intermittent lockouts that clear on reset but return
  • Visible damage, heavy contamination or deterioration of the electrode tip

Before you order

  • Confirm the appliance model and GC number against the fitment list above
  • Check the existing electrode part number against the manufacturer's parts list for your appliance
  • Inspect the electrode and its lead for contamination, cracking or poor connection before condemning the part
  • Confirm the boiler's model variant, as fitment is limited to the Cs/1-5 (2023) range
