Unidentified parts found in John Lewis JLWM1204 filter

[RichardJolly]

15mm fibre ring or washer and 17mm flanged and ribbed white silicone plug or ring (see photo attached) found in filter of John Lewis JLWM1204, product no.914530560/00.  I don't recognise these as having been in a pocket of mine and I cannot find anything similar in a spares list.  Could they be parts from the machine itself, which appears to be working normally?

Hi. As far as I‘m aware there's never any part on a washing machine that could find its way into the pump filter. Anything found in a pump fitter must have been put in the drum, soap dispenser, or left in a pocket.

Thanks for the quick response.  That's reassuring!
