What it is
The Vaillant 0020210206 is a wiring harness with an integrated coding resistor, used on Vaillant ecoTEC Plus gas boilers. It carries the electrical connections between components within the appliance, with the coding resistor identifying the harness to the boiler's control electronics. It is supplied as a single harness assembly.
Signs this part needs replacing
- Boiler fails to run or locks out with wiring-related faults traced to the harness
- Coding resistor faults causing the control board to misread the harness
- Cracked, chafed or heat-damaged insulation on the harness leads
- Corroded, loose or burnt connector plugs at either end of the harness
- Intermittent operation that changes when the harness is moved or reseated
Before you order
- Confirm your appliance model and GC number against the fitment list above
- Check the variant of your boiler (VU, VUI or VUW) matches the listed models
- Inspect the existing harness connectors and coding resistor so the replacement matches what is fitted
- Verify the part number 0020210206 against the manufacturer's parts list for your appliance
