My thermomix has started making an odd rattling sound on low speed. It may be there on high speed as well but I can't hear it over the sound of the motor running. At first I thought there was a large piece of something that hadn't been chopped up properly floating around in the bottom of the bowl, because that's what it sounds like, but there was nothing there. I didn't think much of it, but I've heard it a few times since so I'm getting concerned!
It seems to disappear when it has been running for a few minutes. Today I made vanilla bean paste, so all that was in the bowl was sugar, vanilla beans and water, so very liquidy contents in the bowl, and for the first 5 minutes it was rattling. Once I'd stopped to scrape down and started again, it was gone.
Any suggestions? My TM is 3 years old this month. Thanks in advance.
