What it is
This is the seal used with the electrode kit on Worcester Bosch Greenstar 1000 series boilers. It forms the sealing element around the electrode assembly, keeping the combustion chamber and its connections gas-tight and preventing condensate or flue gases from escaping at the electrode entry point. The part is supplied by Worcester Bosch as a pack of five seals under part number 8738902787.
Signs this part needs replacing
- Visible hardening, cracking or flattening of the seal where it seats against the electrode assembly
- Soot staining, moisture or condensate tracking around the electrode entry point
- Repeated ignition faults or flame detection errors following electrode work
- A seal that has been disturbed, stretched or damaged during service and will not reseat cleanly
Before you order
- Confirm the boiler model against the fitment list above, as the seal is specific to the Greenstar 1000 series
- Check the existing seal against the electrode kit fitted to the appliance before ordering
- Note that the part is supplied as a pack of five, so confirm how many seals the job requires
- Verify the manufacturer part number 8738902787 on the appliance documentation or the part being replaced
