Another one bites the dust
First I wore out a KA 6qt mixer. Now I've about killed a Bosch Universal Plus. Believe it or not, it was not heavy dough that did it in this time. It was a smoothie. I should have learned long ago that multi-purpose machines do plenty but most of it poorly.
After adding the blender attachment and enjoying several smoothies, the blender decided to let one drain into the machine. Nice. Now the BUP sounds like a saw. I do not know if it can be salvaged.
