What it is

The Baxi Cable - Flow Sensor is the wiring harness that connects the flow sensor to the appliance control on Baxi Aquaheat Hi/HWI units. It carries the sensor signal used by the boiler to monitor water flow through the appliance. The cable is supplied as a single service part under Baxi part number 7879291.

Signs this part needs replacing

  • The appliance reports a flow sensor fault or lockout that persists after the sensor itself has been checked.
  • Intermittent or erratic flow readings during demand, with the boiler cutting in and out.
  • Visible damage to the cable, such as chafing, a trapped section, or a broken or corroded plug.
  • Continuity testing across the cable shows an open circuit or a reading outside the expected range.
  • The connector will not seat securely on the sensor or the control board.

Before you order

  • Confirm the appliance model against the fit list above, as the cable is listed for Aquaheat Hi/HWI 4/50 and 14/50 only.
  • Check the part number on the existing cable or the manufacturer's parts list for your appliance.
  • Inspect the sensor and control board connectors for damage before replacing the cable alone.
