What it is
The 87161424970 is a gas valve supplied by Worcester Bosch for use in its older floor-standing and wall-mounted boiler ranges. It sits on the gas train and regulates the flow of gas to the burner, opening and closing under the control of the boiler's ignition and modulation sequence. It is a serviceable component, so it is replaced when the valve no longer opens, closes or modulates correctly.
Signs this part needs replacing
- The burner fails to light and the boiler locks out on an ignition fault.
- The boiler fires intermittently, or drops out shortly after the burner has lit.
- Flame is present but the boiler will not modulate, running only at a fixed rate or cycling.
- Gas is audible at the valve when the appliance is off, or there is a smell of gas at the boiler.
- Repeated lockouts that clear after a reset and then return within a short period.
Before you order
- Confirm the GC number on the appliance data badge matches one of the numbers listed above; the same part number is used across more than one model range.
- Check the existing valve against the alternative and previous numbers listed, as earlier stock may be marked with a different code.
- All parts are non-returnable and non-refundable, so verify the part is correct for the boiler before purchase.
- This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
