Yes, it's time for a reminder to clean your machines. They work hard for us and ask so little. A bit of canned air, a little oil, some lubricant, a new needle, a gentle wiping off of dust.
I'm hoping that this is not what you find when you open the bottom....
Yes, that is an enormous amount of lint and a ... what the!?!? ... PIN! Even lint around the gears at the other side of the machine.
Oh, MY!!!! In the owner's defense, she had just acquired the machine and she was as shocked as the rest of us.
In the end, this machine was spic and span inside and out and ran like a top. She breathed a sigh of relief that she was now in good hands that would not let this happen again. The moral of the story? A little TLC and maintenance go a long way to keeping that machine humming along.
