What it is
The Worcester Bosch 87101030450 is a replacement washer measuring 18.6mm outer diameter, 13.5mm inner diameter and 1.5mm thick, supplied in a pack of ten. It is a sealing component used across Worcester Bosch boiler ranges including Greenstar, CDi, Danesmoor, Heatslave, Highflow and i Series models. Washers of this type sit at joints between components and pipework, and are used in areas such as heat exchangers and gas valves to prevent gas and water leaks.
Signs this part needs replacing
- Water weeping or dripping from a joint on the heat exchanger or associated pipework
- A gas smell or a detected leak at a gas valve joint
- The washer looks flattened, cracked, hardened or perished when a joint is opened
- Staining, scale or corrosion around a joint that has been disturbed and refitted
- Repeated pressure loss with no other obvious source
Before you order
- Check the GC number or the rating plate on the appliance to confirm this washer suits your model
- Match the part number 87101030450 against the washer being replaced before ordering
- Washers are often renewed together with O-rings and gaskets when a joint is broken, so check whether a seal kit is also needed
- This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
