Hi. I've had my KitchenAid blender for about 5 years. Admittedly it's had very little use in the last year but when I tried to blend something in it last night the black plastic thing on top of the base that the blender sits on just fell apart into dozens of pieces. It looked fine before I put the blender on the base but when I switched it on although it made the right noises it didn't blend. And when I took it off again there was the thing all in bits. Has anyone else had this problem? I know the blender isn't new but I was still pretty since they are pretty expensive. Prior to this I had my grandparents ancient old Kenwood blender and it lasted a good 25 years. Was still going strong when I got this one. Does anyone have a clue how long the guarantee might be on these things or how I might go about sorting it out? It was a present so I don't even know where it came from.
