Thanks everyone, I ended up taking it in for service. He fixed it and declared it to be running well. (Husband is putting it back in the cabinet for me now.) I also learned that I have a 401g not a 401a. I had never heard of the 401g so when I saw 401 on the manual, I assumed I had the 401a. Now I'm reading a
helpful post started by Miriam about the 401g.
