How did the replumb project go? Did it fix anything?
My Zymatic stopped heating and it's out of warranty. I ran the full system test, and it appears the heat pump doesn't work. Keg and drain pumps work, but when it gets to heat pump test, nothing fires up. I've run cleaning cycles several times and gunk comes out, but it doesn't heat up on its own.

@seabrew several of us have replaced the motors with better ones, replumbed all the lines and done some minor upgrades to the HEX loop that improves performance and increases the time between glycol loop top offs. I am crrently putting together the procedure for the mods, but I do have a procedure for the HEX maintenance if you want to try that first, its been used by nearly 50 folks on here with great success.
As for Picobrew, you can stop going to them for answers and help because at this point I think this forum has become the expert knowledgebase. The only thing we can't fix right now is a main board issue, but I'll have that cracked very soon.
PS Still working on the stainless steel step filter...I've actually just been too busy to get to it.
