Hi, does anyone know what could be causing a shrieking sound from my Servis Quartz 262 dryer? Basically, it starts fine and within about 10 seconds makes a fairly ungodly shreiking sound. It's continuous sound, though I turned it off immediately so as not to bring hoards of concerned neighbours thinking I was harming animals... Additionally any ideas where I could find a replacement fluff filter for the drum? I've got a sinking feeling that it won't be easy...
