What it is
The Worcester Bosch flap assembly is a casing component used on Compact, Greenstar and Greenstar ErP boilers. It forms part of the outer casing, where it covers an access opening and keeps the boiler's finished appearance intact. Casings differ between models to suit different installation locations, with varying levels of robustness and a range of finishes, so the correct flap must be matched to the appliance.
Signs this part needs replacing
- The flap is cracked, snapped or missing from the casing
- The flap no longer sits flush or will not stay closed
- Rattling or vibration noise coming from a loose casing flap
- Discolouration or heat damage visible on the flap surface
- The flap has come away from its hinge or fixing points
Before you order
- Check the GC number on the appliance data badge against the compatibility list to confirm the correct casing variant.
- Confirm the part number 87186864950 or the alternative number 1030961 before ordering.
