What it is

The Viessmann air pressure switch connection cable, part number 7818165, is a wiring lead that links the air pressure switch to the boiler's control circuit. It is listed for Vitodens 100 and WB1A appliances built from 12.08.2005. The cable carries the switching signal that allows the boiler to prove fan and air pressure conditions before ignition.

Signs this part needs replacing

  • Boiler attempts to fire but locks out before ignition
  • Fan runs but the burner does not light, with an air pressure fault indicated
  • Intermittent lockouts or fault codes that clear and return
  • Visible damage to the cable, such as chafing, cracks or a loose connector
  • Connector plugs at either end showing corrosion or poor contact

Before you order

  • Confirm the appliance model and, where shown on the data plate, the serial number against the fit list
  • Check the boiler build date, as this cable is listed for units from 12.08.2005
  • Inspect the existing cable and connectors to confirm the fault lies with the lead rather than the air pressure switch itself
  • Compare the connector type and routing with the cable being removed
