There is definitely a variation in manufacturing quality with the plates and malt tube. My original was an absolute pig to get the seals to stay on. Tried all the tricks mentioned above. No joy. 15 mins of cursing and they would fall off at the end of the mash.
When my unit developed a fault and I had a replacement tube and plates, the new ones are so easy to fit with a bit of grain dust. Works every time, first time definitely understand peoples different experiences here.
 
I've had these since they came out and they are pretty good and simple to use.

One thing I've noted is that you need to use the right pipework, so if you're getting these get the micro pipework too. On smaller malt bills you can end up with the overflow too high above the plate at the lowest setting as the top plate will settle on the malt and the overflow won't adjust down far enough. Not the end of the world.

Make sure you tighten the pipework sufficiently, the whole assemble has a bit more movement then the sealed plates so you need to reassure yourself that the overflow isn't coming undone.
 
Maybe a silly question, but which way up does the bottom plate need to go - rolled lip up or down? 🤔
 
That's fine, but they don't need to be tight PIA to achieve that. A 0.5mm gap all round would still stop the grain. The rest of it is full of holes 😁

You will know this isn't an issue on a BM and they are prolly 1mm all round.

I don't think it is an issue with the new plates if they are the same as the Guten and Hop Cat. The lock-in screens don't need to be a tight fit.

Well what happens is they lower them in the water and if they are too loose they move and may end up on an angle, the grain gets put in and goes through the bottom. It was actually the manufacturers of the Hop Cat who first did the lock-in screen. I told the manufacturers of the Guten and they followed suit. Bevie must have been told at some stage so they did it with the Grainfather.
Such a simple idea and it took so long for someone to think of it.
 
Is it worth buying new seals first? For the first time yesterday I nearly threw my GF over the fence out of frustration with the seals. Never had to much of an issue before but I think the seals might have stretched over time and therefore slip off easier
