I've only had it for about 2 months and it's hardly been overworked, used maybe 10 or 15 times. Yet it sounds like it's straining - when you increase the speed, it does not sound healthy at all. It's not all the time, it's just some of the time, and enough to make me worry.
This isn't right, is it? I went to a kitchen shop this weekend whilst I was out and about, and they said to call KA not John Lewis - but I need to be able to describe the sound. And seeing as how I have no idea, they said the only thing I could do would do is to record it and play it back.
John Lewis or KA will think I've completely lost the plot if I do that, won't they? I'm hoping this is some commonly known yet easily fixable problem!!
