My West Bend 'America's Best' bread machine is making squeeking noises as it kneads the dough. Has anyone had any experience with this? I have had this machine for 18 months and it has made from 3 to 4 loaves of bread a week. Is this what I can expect from this machine? Any help that you can give me will geatly be appreciated. I also remember reading on the boards about a site that has info on new machines, but can't seem to remember which board topic.
