4055578787 Genuine Agitator Lint Filter for Simpson, Westinghouse Top Load Washing Machines SWT604 SWT554 SWT9542 36S605M 22S750L LT955SA

If lint keeps ending up on your clothes, the agitator filter in your Simpson or Westinghouse top loader may be torn or missing. Part 4055578787 is the genuine filter bag assembly, and it clips into place inside the agitator. It replaces 0564257398 and 4055663373 and is listed for Simpson SWT604, SWT554 and SWT9542, the Simpson 22S and 36S ranges, and Westinghouse LT top loaders such as LT955SA.

What the agitator filter catches

As water circulates during the wash, it flows through this mesh bag, which traps lint, fluff and loose threads before they settle back onto the load. A split mesh, or a filter that has fallen out, lets that debris go straight back onto your washing, leaving dark garments covered in fluff. A filter that's never emptied stops working too, because water can't pass through a packed mesh. Emptying it every few washes keeps it doing its job, and replacing it once the mesh tears or the frame cracks is a quick fix.

Clipping in the new filter
