I took my machine in to get cleaned and came back working worse. Took it back in and they said nothing was wrong. I took it home frustrated that it came back in worse condition that it was before. I think they might just not be knowledgeable about my older machine (if they aren't they should have told me). When I was home, I pushed every button multiple times, unplugged and screwed apart and put back a bunch of the pieces and it it started to work like it used to. I don't know what they did, or what I did--but when I spend $70 to get my machine serviced, I'd like it if it came back in the same, if not better condition than when it left my hands.
