What it is
The Worcester Bosch 29160110100 is a flat M4 washer used across a range of Worcester Bosch boilerhouse and CAM 5 appliances. It sits beneath a fixing to spread the clamping load and help keep the joint face sealed. As a service item it is renewed when the original washer has flattened, corroded or started to weep.
Signs this part needs replacing
- Water weeping or a visible drip at the joint the washer sits behind
- Rust staining or white scale tracking around the fixing
- The washer feels hard, flattened or cracked once the joint is opened
- A joint that will not seal after reassembly using the old washer
- Corrosion on the washer face or on the mating surface beneath it
Before you order
- Check the appliance GC number or serial plate and confirm the model appears in the compatibility list
- Compare the old washer against the M4 flat profile before fitting
- Cross-reference the previous number ZGWSH009 and alternative number 1011173 against older paperwork
- Order any associated seals or gaskets for the same joint if they are being disturbed
