What it is

The Saunier Duval 0020085886 is a flue sensor with a water pressure sensing function, supplied as a service component under the Saunier Duval part number 0020085886. It is a sensor assembly rather than a mechanical spare, and it sits within the appliance's monitoring circuit. The supplied product name identifies it as SAUN 0020085886 FLUE SENSOR WATER PRESSUR.

Before you order

  • Check the part number 0020085886 against the number printed on or alongside the existing sensor.
  • Confirm the appliance model and, where available, the serial number against Saunier Duval service documentation to establish the correct sensor for that build.
  • Inspect the sensor connector and wiring harness for damage or moisture before fitting, as these can affect the readings the sensor reports.
  • If the appliance reports a flue or water pressure fault, verify the fault code against the manufacturer's diagnostic guidance before ordering, since the sensor is one of several possible causes.
