What it is

The Worcester Bosch 87186889730 is a wall frame assembly, a casing component that forms part of the outer structure of the appliance. It holds the boiler casing panels in correct alignment so they sit square against the chassis and the appliance keeps its intended clearances and finished appearance.

  • Visible cracks, distortion or corrosion on the frame
  • Fixing points or lugs broken, so panels cannot be secured properly
  • Movement or rattle in the outer casing when the appliance is running
  • Frame damaged during a previous service or panel removal
