Whirlpool Front Loading Duet Washing Machine Plastic at drum front shredding

I think your talking about the rubber door seal????
you can change this yourself,,,under the seal on the case is a wire spring unhook it and the door seal will fold inside the washer,,,on the inner drum you will find the other wire spring undo this as well and pull the old door seal out through the hole in the door,,,the new seal is fitted to the iner drun first so you need to turn the new seal inside out to fit it,,,push the seal into the washer and fit the inner wire first then unfold the seal and fit it over the outer door so you can fit the wire spring,,,
easy after you have fitted a fuw 100?
