What it is

The Vaillant 0020268794 is an NTC temperature sensor used on Vaillant VU 606/5-5 appliances. The sensor provides temperature feedback to the boiler's control system so that flow and return conditions can be monitored and the appliance regulated accordingly. It is a service part listed by Vaillant under part number 0020268794.

Signs this part needs replacing

  • Boiler locks out or shows a temperature-related fault code
  • Flow or return temperature readings that are clearly wrong or unstable
  • Heating or hot water output that cycles or cuts out unexpectedly
  • Sensor resistance readings that are open circuit, short circuit, or drift outside the expected range
  • Fault appears or clears as the appliance warms up, pointing to a temperature-dependent sensor fault

Before you order

  • Confirm the appliance model and GC number against the fitment list above
  • Check the part number on the existing sensor matches 0020268794
  • Inspect the sensor connector, wiring and mounting point for damage before fitting
  • Verify the correct sensor location on your appliance, as more than one NTC sensor may be used
