What it is
The Worcester Bosch 87377014500 is a sealing service cover used on Greenstar 8000 Life appliances. It sits over the service access point and forms a tight, airtight seal that keeps combustion-related components enclosed and prevents leakage from the joint. As a sealing component it is subject to heat cycling and compression, so it is replaced whenever the seal is disturbed or shows signs of deterioration.
Signs this part needs replacing
- Water or condensate weeping around the service cover joint
- Visible staining, crusting or discolouration at the seal face
- The cover seal feels hard, flattened or brittle when handled
- The cover has been removed for servicing and the seal no longer sits correctly
- System pressure drops repeatedly with no other obvious source of loss
Before you order
- Check the GC number or appliance serial plate to confirm the model matches the compatibility list
- Confirm the alternative number 2249286 against any documentation you hold for the appliance
- Inspect the cover and surrounding seals while access is available, as other gaskets in the assembly may need replacing at the same time
- This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
