That was quick HR, so I have heated the unit again and took Fat Freddy`s advice and gave the WPA a bit of attention and gave a quick lick around the bowl and pushed....harder than I would have liked, but, it did go in . It takes a considerable amount of force to get in/out, is that OK? As I said above, it is quite out of round and I think this is causing the extra effort, I would hate to break something.
