What it is

The Baxi 7809597 is a flow switch used in Baxi heat pump appliances. It detects water flow through the heating circuit and signals the appliance control when flow is present, allowing the unit to run safely. It is fitted across the Baxi Assure HP and HP40 heat pump ranges.

Signs this part needs replacing

  • The appliance fails to start or run despite the pump operating and water circulating
  • Flow-related fault codes or lockouts appear on the appliance controls
  • The appliance runs intermittently, cutting out shortly after starting
  • No flow signal is registered at the control board during a demand
  • The switch shows signs of damage, debris or sticking in the water circuit

Before you order

  • Confirm the appliance model against the fit list above
  • Check the part number on the existing component matches 7809597
  • Inspect the water circuit for debris or scale that may have affected the switch
  • Verify the fault is traced to the flow switch and not to the pump or system flow rate
