Replacing out the burr set is only 6 screws and the coarser grounds are far superior to even the coarsest setting on the Vario with the ceramic burrs...really glad I did it!

I may go ahead and do that.  I went ahead and calibrated the Vario-W and it was adjusted to be too fine - you could hear the motor laboring even before I moved the macro slider all the way up.  Even with the new coarser setting I'm still having issue with the air leak it seems - which is unfortunate because I really don't want to have to send it in.  I'm moving at the end of this week and so I will likely call Bunn if the issues continue but will probably try a new roast in the meantime and see if a lighter roast resolves the problem as well.

So far my only dislike is cleaning the part that drops down into the brew chamber. Making sure that it is clean and ground free after each use. It's nothing major, but Im a strictler for clean equipment, and my grounds always end up all over it.

^^^ You're probably making 12-oz. cups, right? I usually do 10 oz., and I've never had the problem you describe; I believe the two might be related.

I do 12 oz. brews exclusively and cleaning the shower head after each brew session is normal procedure for me. A damp paper towel folded in quarters easily wipes the brew chamber shelf and exit diverter and then a quick wipe of the shower head to get the bloom residue and coffee grounds off. This constant wiping of the shower head eventually pushes coffee "crud" up into those two screens which hold the two check valves. Every month or so I lower the panel that holds them and clean everything out well. Hope this helps and take care!

It really wouldnt matter much in my case I dont think. Although I do run 12oz.

Im also roasting at home, so my grounds are always fresh. When the bloom starts it's almost inevitable that it will hit the top.

Again, not a real complaint, still LOVE the machine. And wiping it clean after every use is really not a big deal.

Does anyone else have water escape the heating chamber, and back into the visable resivoir when the pressure pushes the brew out?

This happened when I was running some cleaner through it last night. Noticed it around the 4th brew in a row.

If you always do 12 oz. brews, and even are careful filling the reservoir to only 12 oz (proper line), I find some will leak out during the tank heating for the next cycle. Doing a quick 8 oz. brew once in a while will remedy this. I'm thinking that the 12 oz. measurement line is not "exact" and over a few brews you are gradually  filling the tank past the 12 oz. capacity and the extra is boiled over into the reservoir (if it is in place) or all over the shelf and coaster, if not. Constant 12 oz brews on this machine is pushing it to it's limit. Grind must be right and careful attention to bean density. When I see the push-out phase straining a bit, I know I need to make the grind coarser to prevent a brew chamber seal leak. African coffees seem to be the most troublesome for me and the Trifecta. The wetted grinds seems to have a "snowball" clumping that easily occludes the filter and causes increased pressure in the brew chamber and the shower head seal to leak. I've learned to live with it, for I love the Trifecta and also 12 oz brews. Hope this helps and take care!

Jim

Whoops, just read you post a little closer. Sound like you need to clean the two check valves in the shower head. Seems like the water inlet check valve is partially open (coffee grounds) and when the air enters the brew chamber to press out the coffee, air is also entering that partially opened valve and pushing water back through the heating tank and back into the reservoir. Common problem with fresh coffee, 12 oz brews and coffee crud infested check valves. Loosen the screw that hold the check valve cover plate on the underside of the shower head. Phillips screw head is probably full of coffee grounds and need to be cleaned a bit first. There is a small indent for your fingernail on the right edge of the plate to pry it loose/down. If the two check valves don't come out with the plate, grab them with your fingers and take them out of the shower head. Clean both well, along with the plate/screen holes and the two holes in the shower head that the valves actually press into. The valve with the black O-Ring (water inlet) goes in the right hole and the valve with the red O-ring (air inlet) goes in the left hole. I usually push the two check valves into their respective holes in the shower head first and then place the cover plate on and screw it in. This should solve your problem. Sorry for the first post, but there's probably some good info for you in there anyway. Take care!

Jim
