What it is

The Ideal 171158 is a flowswitch supplied for Ideal 14-section commercial boilers. It monitors water flow through the appliance and signals the control system once flow is established, allowing the boiler to move through its firing sequence. The part sits within Ideal's commercial spares range and is used across the Viscount GTE family of appliances.

Signs this part needs replacing

  • The boiler fails to fire or goes to lockout despite a call for heat
  • The pump runs but the burner does not light
  • Heating or hot water is intermittent, with the appliance cutting out mid-cycle
  • A lockout clears on reset but returns shortly afterwards
  • Fault codes relating to water flow or flow proving appear on the controls

Before you order

  • Confirm the appliance model and section count against the compatibility list before ordering
  • Cross-reference the previous number 88024745 if your documentation lists it
  • Inspect seals and gaskets on removal and replace any that show signs of wear
