Use a different bowl, different material in a different area. Before you put it down put something edible for you to eat in it and let him see that you eat something from the bowl. Then make him sit and wait before you allow him to eat to make him eager. Give it and leave him alone and do something to distract yourself, no attention for him whatsoever. Give him about 15 minutes to eat and remove everything after that.
I had a brief issue with WD after using an interactive feeding cube (to keep him busy) so he had learned that by pushing the cube around it would release kibble. Then he started it with his full regular bowl as well. I took it away a few times and he hasn't done it since, nor has he had the cube again. That whole thing kept me busier than him.
