What it is
The Worcester Bosch cover top screw assembly, part number 87186807500, is the fixing hardware that holds the top cover panel in place on Greenstar Ri ErP Compact gas boilers. It is supplied as an assembly rather than a single loose fastener, so the cover can be lifted off and refitted during servicing and then secured again cleanly. Worcester Bosch uses this fixing across the Greenstar Ri ErP Compact range in both natural gas and LPG versions.
Signs this part needs replacing
- The top cover panel sits loose, lifts at one corner or rattles while the boiler is running.
- The screw head is rounded, chewed or seized, so the cover cannot be removed with a normal tool.
- The thread in the cover fixing point is stripped and the screw no longer tightens.
- Rust, scale or corrosion is visible on the screw assembly or around the fixing point.
- The fixing is missing altogether after a previous service or repair, leaving the cover unsecured.
