Have to give @Mike Howard a shout out and HUGE thanks for the Hex Loop refill instructions. I finally went thru and spent the time to refill my hex loop... took about 8 oz of Glycol! Got the first full regular cleaning cycle thru the thing in about 2 years. I had brewed on it for only one trouble filled session, then couldn't get a cleaning cycle to complete without a FE #1. Thru moves, and busy schedule, and a determination to brew when in the brewery, and not tinker with equipment it took that long.

I have not set a definitive price yet, but I'm thinking of offering it in multiple ways:

1. Complete turnkey for those not electronically/mechanically inclined. Complete board, Raspberry Pi, pre-loaded with software, pre-configured and fully tested on my test Zymatic. Only minor mods to the configuration will need to be made. $$$$$*

2. Complete board, fully tested. You provide the Raspberry Pi and install the software yourself. $$$$*

3. Bare board with components, you solder them on. Provide your own RPi, etc... $$

4. Bare board, no components. You purchase components separately and solder them on. Provide your own RPi, etc... $

Eventually I want this all on github and open source. Folks can download the source files, build their own boards, modify the code, etc... The only money I'm trying to procure is to cover the development costs of the board.

* I'm only one guy with a full time job, so building boards, testing and getting them sent out, could be on a long delay.
That sounds amazing, once again thanks for your work! :D

Do you have any idea when you fell comfortable releasing your work?
I personally would be happy about version 3 or 4 to minimise your work load.
Or even 5: Just the schematics.

Putting everything open source would be amazing and would enable other Devs to help out with the codebase and testing.
And issue tracker and wiki so the problems and the knowledge is not spread out across multiple monster threads in this forum.

And I think nobody would resent you charging a bit of a markup on the hardware. ^^

Quick question. Is it possible to remove the rubber plug in the step filter? If so, how? Looks like there is a build up of trub on mine that I'd like to clean off, and there is a crack on the underside of the step filter there I'd like to inspect before I attempt to repair.

@Mike Howard Would you be so kind as to share your glycol refill instructions? I picked up a "new" machine and I believe the glycol loop is angry. Would it be a good idea to go ahead and replace the pumps?

I PM'd you about the glycol refill instructions.

As for the pumps, you probably don't need to replace them. I'd get the glycol refilled and then do several cleaning runs. Might also be worth doing a deep clean with PBW (being careful not to let the PBW touch your step filter).

If the machine has sat for awhile the HEX probably needs a good PBW soak and while you are in there if the hoses look really bad, it might be time to replace them.

@Trevor Mack Do you have any experience running the picobrew_pico as a container? I pulled down the Unraid container and was able to access the web UI but never was able to get the Zy to connect.

@Trevor Mack Disregard. My FW was blocking inter-vlan traffic. Moved the container to another vlan and set a local DNS entry into my PiHole for the PicoBrew server.

Last fall I bought a used Zymatic, which I subsequently refurbished with a super-thorough cleaning, new internal hoses, a new pump, step filter crack repair with Weld-On 3, and a glycol top up. I liked it enough to buy a second step filter, which unfortunately was cracked to a similar degree, but now repaired. Then, a brand new Z1 became available and I pounced on it. Although I suspect that its pinch valve may eventually prove problematic, I decided to standardize on the Z and bought a Z2. With three Zs, I no longer need my Zymatic. I wish only to recover most of what I put into the Zymatic, even though the buyer will greatly benefit from my hours of labor and also the assistance I received from the PicoBrew community, like Mike Howard, Trevor Mack, Ender Wiggin, Justin Hart, and others.

I have listed it on the For Sale forum here: Picobrew Zymatic

Mike,

I am new to this forum. I have found this thread to be most enlightening as I have been a Zymatic owner for a number of years now. As others have experienced, FE#1 is frustrating. I have been preheating my water prior to brewing which gets me through the single step infusion mash, but still having issues when raising temps in a multi-brew mash. If you would please send me your instructions for the glycol refill, it would be much appreciated. Many thanks in advance!!

I noticed that the instructions for glycol top-up were recently uploaded to the Files section of the Picobrewers group on Facebook, but now I don't see it for some reason. I have a copy, but I think the author, Mike Howard, prefers to send them out himself, perhaps to establish a line of communication in case of questions.

Think it is more to communicate and set expectations at the skill level of the recipient, vs having people get hurt or break their machines more by not actually reading the instructions fully. Though Mike may have other reasons as well, just make sure to unplug the machine before opening it up and "poking" or "proding" around things you may not understand.

I know this isn't going to have an "active" zymatic profile, but hey a Zy is basically a Z (or rather the other way around).

Anyways I've deployed a dev pipeline for my fixes and updates purposed to BrewCrafter at crafter.pilotbatchbrewing.com feel free to give this "alpha/beta preview" a spin. No clue when these new features (PicoFree / PicoPak recipe, and newly fixed email integration) will get merged into the "official beta crafter" experience.

I had the file removed, for the reasons Trevor quoted, and to be personally involved with anyone needing the procedure. I am more than willing to send it to anyone who needs it, except some of those jacks at the now defunct PB (they know who they are).

Hi Mike, I'm also a zymatic user and getting the dreaded error #1. It's circulating fine but suspect it may need some refurbishing. Any chance you could share the procedure with me as well? Thanks much.

Mike - I am having issues with overheat and would be interested in getting the refill instructions as well. My Z's are getting tired - 50 brews each now and need a tune up. Trying to brew 8 kegs for my friends wedding and on Keg 5 and running into overheats.
