Kenwood Chef with a mind of its own?

This is a bit of a guess but could it be to do with heat. I once had a Kenwood chef where the Triac component had gone. it ran at full speed all the time. I changed the triac and one of the capacitors and it worked fine.

Maybe the triac (translation: speed controller) is on the blink and when it gets hot lets too much current through (hence max speed).

Here is a link to another thread which discusses a similar problem.
