What it is
The turbine is the flow-sensing component used on Worcester Bosch Greenstar 8000 Life combi boilers. Water passing through the domestic hot water circuit spins the turbine, and the sensor signal it produces tells the boiler that a hot water tap has been opened so it can fire and modulate to demand. It sits within the boiler's sensors and switches group and is supplied as a single unit under Worcester Bosch part number 8737602353.
Signs this part needs replacing
- No hot water production when a tap is opened, with the boiler failing to respond to a domestic hot water demand.
- Intermittent hot water, where the boiler fires and then drops out during a draw-off.
- Hot water temperature that fluctuates or runs cold despite the heating circuit working normally.
- Fault codes or lockouts logged against the domestic hot water flow sensor circuit.
- Debris, scale or a worn impeller found on inspection of the turbine body.
Before you order
- Check the appliance GC number or serial plate against the compatibility list to confirm the turbine suits your model.
- Confirm the part number on the existing component matches 8737602353 or the alternative number 2249302 before ordering.
- This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
