Posted Fri Feb 7, 2014, 1:00pm Subject: Water escaping through side of dispersion block?
I had to replace the dispersion block/screen on my Oscar, as the previous owner had installed a pod adapter...
I purchased the kit (sold as being specifically for the Oscar) from Chris's Coffee, which included the block, screen, screw, and baskets. I also ordered a gasket (again, said in description that it would fit the Oscar)
Now, it seems some water is not going through the screen, but instead, out the side and then down between the gasket and the dispersion block. I believe I sufficiently tightened the screw (which a ratchet), so I'm wondering what gives.
I must point out, the gasket I got from Chris's was not identical to the one I replaced (the one I replaced had a V-like shape the extended down along one of the edges--the one that comes in contact with the portafilter).
I am wondering if a surface just needs cleaning, or if perhaps it isn't actually the same as the original dispersion block?

Is there any sort of groove in the screen or block that the gasket could fit into? Normally the water pressure is supposed to cause the ring to fill the gaps, but if you didn't sufficiently seat it or tighten the screen down that could be the problem.
