Re: kitchenaid 250 watts k4ss mixer
The repair manual says that the mixer can make this grinding sound at slow speed, like stir or 2. This is normal, especially until it warms up. This is the sound of the gears turning at slow speed.
the grinding noise becomes louder and more irritating when the speed is increased. It started all of a sudden. The mixer is 25 years old or so.
