What it is
The FLOW REGULATOR TYPE E-W-LP 12 LITRE is a Worcester Bosch boiler component listed under gas boiler spares as a flow switch. It is manufactured by Worcester Bosch for use in the Greenstar appliance family. The regulator manages the water flow rate through the boiler circuit, allowing the appliance to sense and control flow correctly.
Signs this part needs replacing
- Boiler fails to detect adequate water flow and does not fire on a hot water or heating demand.
- Flow rate at the outlets is noticeably reduced or inconsistent compared with normal operation.
- Boiler cycles or modulates erratically because the sensed flow rate is unstable.
- Visible scale, debris or damage at the regulator body or its seating.
Before you order
- Confirm the appliance model and GC number match the fitment listed above.
- Check the existing regulator type marking to confirm E-W-LP and the 12 litre rating.
- Inspect the surrounding water circuit for scale or debris that may have caused the original fault.
- Verify the part number 8716117158 against the appliance's parts listing before ordering.
