The Baxi 7798983 is a genuine OEM domestic hot water (DHW) turbine cartridge assembly, designed to accurately measure hot water flow within compatible Baxi, Main, and Potterton combi boilers. This turbine plays a critical role in detecting demand for hot water and enabling the boiler to modulate output correctly.

A faulty or worn DHW turbine can result in issues such as no hot water, intermittent heating, fluctuating temperatures, delayed burner ignition when taps are opened, or incorrect flow readings. Replacing it with this genuine Baxi component restores accurate flow detection and reliable hot water performance.
