I'm afraid I can't help with the problem, Angela, but I feel it's worth mentioning that I have a 1015 SE which is quite similar to your 1008 and I've attempted to open it up a few times to do a bit of grot hunting (term trademarked by Roger and Madame Cholet
). On each occasion I've been knocked back by the way it's intentionally difficult to get into. You get the side and back covers off quite easily but underneath that there's a metal panel that needs removing before you can get at anything of note.
I'm definitely not saying that it's impossible but it's not a machine that makes DIY repairs easy. Certainly not as easy as with older vintage machines. Perhaps because it's metal and mechanical I had hoped that it would be different.
Thankfully I've had no problems yet with mine, but when I do, I'll have to think about finding a professional to take it to. That's not something I'd really consider with any of my vintage machines.
