What it is

The Vaillant 0020144361 is a wiring harness supplied by Vaillant for its ecoTEC VU range of gas boilers. It carries the electrical connections between components within the appliance, forming part of the boiler's internal wiring loom. It is listed under the wiring category of gas boiler spares.

Signs this part needs replacing

  • Intermittent electrical faults or unexplained lockouts that clear on their own
  • Fault codes relating to sensors, fans or communication that recur after resetting
  • Visible damage to the loom, such as chafed, cracked or brittle insulation
  • Charred, discoloured or loose connector plugs and terminals
  • Boiler failing to power up or dropping out when the harness is moved

Before you order

  • Confirm your boiler model and GC number against the fitment list above
  • Compare the connector layout and plug count on the existing harness with the part being ordered
  • Inspect the original harness for the cause of failure so the replacement is not damaged in the same way
  • Isolate the electrical supply to the appliance before removing or fitting any wiring
