I have wanted to see and try a commercial Trifecta. Can you let us know when it is back in action?

It was repaired today and seems to be working again.  I'd give it a few days before  recommending the trip down to Devon.

nachoslibres Said:

Another maintenance related question.  I'm doing my regular 3 month descaling/cleaning and decided this time since the machine has had a year of regular use to go ahead and clean the check valves in the brew chambers.  I can get the bottom one out but I can't get the check valve for the air out - and I can see that there is coffee sediment/staining build up on the valve itself.  Is there anyway to take this out without having to take the screws out of the bottom portion of the brew chamber (and is this even recommended)?

I will say I now have the screens in my brew chambers looking like brand new, I just wish there was something I could do to clean off the staining of the bottom check valve (the one I can remove).  But I'm guessing since coffee is continuously flowing over it it will be stained.

Posted December 22, 2013 link


UPDATED INFORMATION!

Initially, I was told that the air injection check valve located on the side of the brew chamber could not be removed. Like you, I was getting tired looking at that coffee residue encrusted check valve on the bottom of my recently-cleaned brew chamber and wanted to do something about it. Figuring that the check valve was press-fit into the hole like all the other check valves were, I was contemplating using one of those dental tool hooks, and from the outside, insert it into the valve, catch the inner lip and yank the darn thing out. Mine have been in for over 18 months and were pretty gross looking, to say the least, so the plan was to replace them if I got them out. I decided to run this idea past Amanda, who then passed me over to Bunn Technical Services. Lo and Behold, I was told that the side check valve CAN be replaced and the maintenance tool that comes with the Trifecta MB will do it. It worked like a charm for me and I replaced the side air injection valves (red) in all three of my brew chambers. Here's how it's done…

  1.  Remove the brew chamber filter screen.
  2.  Insert (from the inside) the end of the maintenance tool with 90º pin, into the hole for the side check valve.
  3.  Press that 90º pin against the check valve to move it outward.
  4.  Tap the black base of the brew chamber against your hand a few times to further loosen the check valve and move it down the hole and out the opening.

I used a narrow tubing brush to throughly clean the "tunnel" that the check valve sits into and then popped a new valve in. Use the end of the maintenance tool with the straight pin to seat the new check valve firmly in the tunnel.

BTW, I was also able to replace the check valve (red) on the bottom of the water reservoir. After removing the strainer from the water reservoir, use the end of the maintenance tool with the straight pin to push the valve out from the inside. It pops out with hardly any pressure for cleaning or replacement.

Hope this helps someone and take care!

Jim

I would like to purchase some new brew chamber valves, but cannot find a link.

Anyone know how to get them?

Send an email to Amanda or Bunn Tech Services:

amanda.crossland@bunn.com

Tech.Service@bunnomatic.com

Most likely they'll send them to you FOC. Here's some parts numbers…

#43811.1000   Rebuild kit (air nipple o-ring and large brew chamber o-ring)
#44668.1000   Set of 5 black check valves
#44164.1000   Set of 5 red check valves

Hope this helps and take care!

Jim

I've been busier lately, and so less chatty online, but I do want to take time to thank you, Jim, for that cleaning info. Very good to know.

Agreed that it's hard to get Amanda to charge you for anything concerning the MB! She recently sent me a new filter removal tool after I stripped mine out trying to remove the filter from a new brew chamber. The new tool didn't help, so I'm using a screwdriver to remove that particular filter until I get a chance to shave it down a little. The filter's the issue, as it's hard to get out of other brew chambers, too. Or maybe I'm the issue, fundamentally, since I feel compelled to remove the filter after each brewing session for a quick rinse and wipe. Excessive tidiness for the win!

Amanda sent an email. She said the valves are free, simply call the number on the back of the machine to order. Sounds good to me!
