What it is

This is a 15 section flow switch manufactured by Ideal for use in their commercial boiler range. It monitors water movement through the appliance circuit and signals the control board that circulation is present, allowing the boiler to fire and run safely. The part carries Ideal's own part number 171159 and the alternative number 88024746.

Signs this part needs replacing

  • The boiler fails to fire even though the pump is running and there is demand for heat or hot water
  • Lockout or a flow-related fault code appears shortly after the appliance starts
  • The burner fires briefly and then shuts down, repeating in a cycle
  • No heating or hot water despite the appliance appearing to run normally
  • Intermittent operation that clears and returns without any other change to the system

Before you order

  • Confirm the appliance model and serial number against the compatibility list, as the same appliance family can use different flow switch variants
  • Check that the existing flow switch is a 15 section type and that the number 88024746 matches the part being replaced
  • Inspect the housing and any seals at the same time, as disturbed joints may need attention during refitting
