Ideal Logic Flow Turbine 12 Litre 175662 Replacement Part

This flow turbine measures domestic hot water flow, so the boiler can detect when a tap is opened and fire correctly. However, over time, limescale or debris can cause the turbine to stick or misread the flow.

As a result, symptoms may include no hot water, hot water cutting out, or temperature fluctuations; in some cases, the boiler may not respond when the tap is opened. Therefore, replacing the correct turbine helps restore stable hot water and reduce nuisance shutdowns.
