Every time I try to make bread, the bowl slipped out of the locked position. I have to stop and try to block it back. Usually you have to completely stop the mixer and pull dough and knead by hand. What can we do? Do I need a new lock plate, bowl or both?

I assume you mean the main part of the console appears instead stays in the mixing bowl, if so, then yes, you need the repair clamp. There is a spring in what the guard down and locked. You'll need to find a repair service that Kitchaid or equipment Hobart. Do not be a big deal long term. It is a simple repair.
