Try cleaning the check valves in both the shower head and also in the water reservoir. Keep us updated.!

It's been hard to diagnose due to it being intermittent. In the past, if I've done anything it was to remove the reservoir and the screen and give them a rinse. Based on your advice, I pulled the reservoir check valve and cleaned it. It was slightly dirty but to my eye not enough to clog it. As usual, it's working again. Tell me: to pull the top check valve do you simply remove the silver phillips head screw?

Just a thought: wouldn't it be nice if the water showered upon all the grounds instead of coming down in a single stream?

DanH Said: Tell me: to pull the top check valve do you simply remove the silver phillips head screw? Posted August 11, 2012 link Yes, also a few posts back describes doing this. There are two "different" check valves in the shower head and they need to be replaced correctly. When you fill your reservoir, do you bring the water to the reservoir while it is sitting on the machine or take the reservoir over to the faucet? The one time I had what you experienced, I noticed my reservoir was not positioned correctly. I only use the supplied beaker to fill the reservoir now. Hope this helps. Oh yeah, it would've be great f they designed the shower head with multiple holes. I've been using turbulence cycles A-D with no problems. Take care! Jim

Aha! Well then I guess we're on the same page. Good to know I'm not alone in how I use the machine.

About the shower head issue, I wonder if Bunn's avoidance of a true "shower" here has to do with the fact the Trifecta's head moves up and down? Or could it be due to potential heat loss? Just curious, though I haven't had any issues with dry grounds.

Or maybe they don't think it improves the flavor (i.e., having grounds get saturated at intervals might be one of the key factors in performance).

I just got a "Brew Chamber Tool" from Bunn (unexpectedly) in the mail yesterday. How cool is that? (Click for larger image)

jbviau Said: What does it do? Posted August 12, 2012 link It's to make routine check valve and filter screen maintenance easier. I got another one yesterday too. After I received my Trifecta MB, I sent an email out to Lisa at Bunn, recommending they include some type of "plastic" tool aid in removing the filter screens and check valves. I felt kinda' funny sticking a metal screwdriver down next to the fragile filter screen. She replied that they already had a prototype tool they were evaluating and would send me out one to try. The one I received yesterday looks exactly like the one I received earlier. It works like described and currently they reside in my cutlery drawer, close by the Trifecta. Take care! Jim

Or could it be due to potential heat loss? Just curious, though I haven't had any issues with dry grounds. Posted August 11, 2012 link I'm thinking it was the logistics of having to position the hot water check valve above multiple holes, in a shower head that really, isn't that thick and is movable. How it is now, servicing that valve is very easy. Not to mention the coffee bloom residue that eventually would work it's way between the check valve and the multiple exit holes. My current coffee is very fresh and blooms up a storm. I have to wipe off my shower head after every brew. No dry grinds though, just stuff on the shower head. It works well the way is it now. I wonder how the shower head is on the commercial version. Take care! Jim

I hope they send that tool to everyone who has purchased the machine.

If you don't receive your's soon, I'd give Lisa @ Bunn a call. The warranty number listed on the last page of your owner's manual seems to be her direct line. Take care! Jim
