What it is

The Worcester Bosch door seal, part 87110043650, is a casing seal used on CDi Series, Greenstar and Greenstar ErP boilers. It sits in the casing assembly and closes the joint around the door, forming a barrier that stops flue gases and water passing out of the boiler. Seals of this type are used at a number of points across the appliance where a gas-tight or water-tight joint is required.

Signs this part needs replacing

  • The seal is cracked, hardened or perishing
  • The seal has flattened and no longer stands proud of its groove
  • Water weeping or staining around the casing door
  • Signs of flue gas escape around the casing during a service or combustion check
  • The seal crumbles or drops away when the casing door is opened
