What it is
The Worcester Bosch 87161563020 is a pilot injector manufactured for LPG-fired Worcester Bosch appliances. It sits in the pilot burner assembly and meters the gas supply to the pilot flame, so the flame is the correct size and shape to light the main burner reliably. The injector is a service item: once the orifice becomes restricted or worn, the pilot flame weakens and ignition becomes erratic.
Signs this part needs replacing
- The pilot flame will not stay lit after the button or ignition sequence is released.
- The pilot flame is noticeably weak, short or uneven compared with normal operation.
- The pilot flame burns yellow or lifts away from the burner instead of holding a steady blue shape.
- Sooting or discolouration appears around the pilot burner and the appliance struggles to light the main burner.
- Repeated lockouts on ignition, particularly on older LPG appliances where the injector has never been changed.
Before you order
- Check the appliance GC number and model plate against the compatibility list, as the same appliance family can use different injectors by fuel type and revision.
- Confirm the previous part number ZBGAS046 against the injector currently fitted before ordering.
- Inspect the pilot burner and its seals while the assembly is apart, and renew any gasket or washer that is disturbed during the swap.
- This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
