What it is
The Worcester Bosch gas valve (part number 8738902772) is the component that regulates the supply of gas to the burner within the appliance. It is used on Worcester Greenstar 1000 Series Gr1000W combi boilers. The valve opens, modulates and closes the gas path under the control of the boiler's electronic management system.
Signs this part needs replacing
- The boiler fails to light, with no gas reaching the burner despite a call for heat
- Repeated lockouts or flame-failure faults shortly after ignition
- Unstable or uneven flame, or the burner extinguishing during operation
- The valve fails to modulate, causing the boiler to run at a fixed rate or cycle
- Gas smell or evidence of leakage around the valve body
Before you order

- Check the appliance model and GC number against the fit list above
- Verify the boiler is the NG (natural gas) variant, not LPG
- Gas valve replacement is a gas safety critical task and must be carried out by a Gas Safe registered engineer
