What it is

The Ideal 175661 is a flow turbine cartridge fitted around the diverter valve section of 30kW combi boilers. A small turbine wheel spins as hot water is drawn off, and a hall-effect flow sensor (Ideal part 175590) reads that rotation to signal demand to the boiler control.

Signs this part needs replacing

  • Boiler fails to fire or is slow to respond when a hot tap is opened
  • Hot water flow feels inconsistent or surges
  • Boiler shows a flow-related fault code
  • Hot water works erratically alongside a known-good flow sensor (175590)

Before you order

  • Confirm the part number and serial prefix on your boiler's data plate against 175661 before ordering, as similar cartridges are used across the range
  • Check the paired hall-effect flow sensor (175590) too if symptoms persist after replacement
  • Fitting is a job for a Gas Safe registered engineer
