Worcester Bosch Washer M10 29160118960

The Worcester Bosch 29160118960 is an M10 washer supplied as a spare part for Worcester Bosch heating appliances. It is a small sealing and load-spreading component used at threaded and bolted joints inside the appliance, where it helps distribute clamping force and keep the connection tight. It belongs to the manufacturer's gaskets, O-rings, seals and washers group of spares.

• Weeping or a visible trace of water at the joint the washer sits behind
• The washer is flattened, split or deformed and no longer sits proud of the mating face
• Hardening or cracking of the material after long service
• Corrosion or scale build-up around the washer and the fixing it seals
• A joint that will not pull down tight, or that loosens again after reassembly

• Confirm the appliance model and serial number against the compatibility list before ordering, as the same washer size is used across several Worcester Bosch ranges.
• Check the old washer against the previous number ZGWSH012 and the alternative number 1011181 to be sure the correct item is being replaced.
• If the joint is being opened as part of a wider repair, check whether any other seals or gaskets on the same assembly also need renewing.
