Worcester Bosch Full Gas Valve 87161424130

The Worcester Bosch 87161424130 is a complete gas valve assembly for Worcester Bosch gas-fired boilers and water heaters. It controls the flow of gas to the burner, opening and closing in response to demand from the appliance's control board, and forms part of the ignition and flame-safety circuit. It is supplied as a full valve rather than a sub-component, so the whole body is replaced in one operation.

• The boiler fails to ignite, or attempts ignition and then locks out
• No gas reaches the burner even though the appliance is calling for heat
• The flame lights but drops out shortly afterwards, or burns intermittently
• Repeated flame-failure faults logged on the control board
• Corrosion, debris or moisture visible around the valve body or its connections
• A smell of gas or other evidence of leakage at the valve

• Check the model and GC number on the appliance data plate against the compatibility list above before ordering.
• Confirm the part number on the valve being removed matches 87161424130, as similar-looking valves are used across the Worcester Bosch range.
• Inspect the seals and washers when the old valve is removed and replace any that are damaged before fitting the new one.
• This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
