Has anyone else had an issue with their Grainfather having the support ring slipping down into the boiler when attempting to lock the grain basket for sparging? I have done quite a few brews with mine but the last 3 or so I have had the ring slip out of the groove it fits into. Yesterday's was the worst. The grain basket made a huge splash of very hot wort over the floor and me. Ouch. It was only about a quart or so but still painful. Should I just try to replace the ring (which I'm not even sure is possible) or is there some other cause I'm missing?
I had to check the instruction booklet to see what you meant by "locking" the grain basket. Sure enough, they mention locking it, but they don't say how that is done. I simply followed the instruction to lift the basket and turn it so the tabs rest on top of the ring, and left it at that.
I looked at mine and didn't see a way it could lock, so I'm wondering what it is you're doing when you're trying to lock it.
