Query: DEFECTIVE..SENT IT BACK

I had to send it back because it would shut off after 10 minutes of cook time. Very disappointed. I've had one of these for years. It still works but the bowl is scratched so I thought I'd replace it. I guess my next choice will be the fuzzy logic. If I have problems there I will have think Zojirushi is not a great company any longer.
