What it is

The Baxi 7662101 is a hall sensor assembly used on Baxi combi boilers. It sits within the diverter valve assembly and provides positional feedback to the boiler's control board. This feedback allows the boiler to confirm diverter valve position when switching between central heating and domestic hot water.

Signs this part needs replacing

  • Domestic hot water temperature fluctuating or running hot and cold
  • Boiler failing to switch correctly between central heating and hot water
  • Intermittent lockout or fault codes relating to the diverter valve
  • Hot water demand not being recognised by the boiler
  • Diverter valve operating but the boiler not responding as expected

Before you order

  • Confirm your boiler model against the fit list above
  • Check the part number on the existing sensor before ordering
  • Confirm the fault has been traced to the hall sensor rather than the diverter valve body or control board
  • Check that the boiler is isolated from the electrical supply before any work begins
