What it is

The Worcester Bosch 29160110120 is an M5 flat washer, supplied as a sealing and load-spreading component for bolted joints inside the appliance. It sits under the fastener head or nut, distributing clamping force across the joint face and helping to keep the assembly fluid-tight. It belongs to the Worcester Bosch gaskets, o-rings, seals and washers spare group and is used across the older 9.24 Electronic and Boilerhouse appliance families.

Signs this part needs replacing

  • Weeping or damp staining around a bolted joint on the appliance
  • Visible corrosion, pitting or surface damage on the washer face
  • Washer crushed, split or distorted after the joint has been disturbed
  • Water tracking down the casing or pipework below the joint
  • A joint that will not seal cleanly after a component has been removed and refitted

Before you order

  • Check the appliance model and GC number against the compatibility list to confirm this washer is the correct item for the joint being worked on.
  • The previous Worcester Bosch number for this washer is ZGWSH010, and 1011175 may appear on older documentation for the same item.
  • Order the quantity required for the joint or joints being serviced, as washers are commonly replaced alongside the fastener they sit under.
