We have a Zanussi ZJD 1285 Washer / Drier 5 years old, and a paddle in the drum broke off. We got a new one and fitted it. Its a "snap on" type part but it also came with a little screw - but dont know where that goes?? Then then the other 2 paddles broke off !! Have you heard of this happenning before & should the new paddles just snap in? There is a kind of blue/grey siicone under each old paddle - should we use silicone under the new ones? Help!!! Do we need a new drum?
