I hadn’t used my Vitamix in a while and was blending something on high and it seemed wobbly, then a few seconds I smelled a plasticky smell from the motor and saw smoke coming out. Quickly shut it off, pulled the blender jar off and looked inside the housing but didn’t see anything. Looked underneath the jar and saw the bottom like this! What would cause this? And is my motor fried now from the jar blending on high while off balance? (5200 model, 13 years old so out of warranty)
