Description
Ideal 175590 Flow Sensor Hall Effect – Part for Ideal & Keston Combi Boilers
The Ideal Flow Sensor Hall Effect 175590 helps your boiler detect water flow accurately, so it can deliver hot water when needed. However, if the sensor becomes faulty, the boiler may struggle to recognise demand, which can lead to poor hot water performance or inconsistent operation. Therefore, replacing it with this refurbished part helps restore correct flow detection and supports smooth everyday boiler performance.
