We have the same brand. It's our second one. Our first one was great, never stuck until DH cleaned it with a scourer and killed the bottom. This one sticks a lot too. I try to reduce it a bit by adding a bit of extra water. I was actually saying to DH the other day that I wonder if its lost some of its non- stickiness due to going in the dishwasher (we didn't put the old one in). Have you put yours in (just out of interest for my own theory).
