What it is

The Baxi Circuit Kit OL PHE-Flowswitch is a manufacturer circuit kit assembly for the Baxi Auriga HP 40T heat pump. It carries the overheat (OL) function together with the plate heat exchanger flowswitch, monitoring water flow through the plate heat exchanger circuit. The kit is identified by Baxi part number 7839661.

Signs this part needs replacing

  • The heat pump locks out or reports a flow fault on the plate heat exchanger circuit.
  • Overheat protection trips repeatedly during normal running.
  • Flowswitch does not respond to established water flow, preventing the appliance from starting.
  • Intermittent shutdowns that clear on reset and return under the same operating conditions.
  • Visible damage, contamination or debris around the flowswitch or circuit kit assembly.

Before you order

  • Confirm the appliance model is the Baxi Auriga HP 40T and that the serial number is 240360222 or later.
  • Check the existing part against the manufacturer part number 7839661 before ordering.
  • Verify whether the fault lies with the flowswitch, the overheat circuit or the plate heat exchanger before replacing the assembly.
  • Confirm acceptable water quality and system cleanliness, since debris is a common cause of flowswitch faults.
