Are you also back flushing it or only going in the wort flow direction?? I run flush water through mine in both directions and have never had any clogging issues. I fill it with PBW solution from time to time too.

Something else you could run through it would be a citric acid solution. Mix it up pretty strong (1 cup per gallon of water) and let it sit with that in it for a few hours. Run it out, rinse and see how water flows through it. You could also try running boiling hot water through it.

BTW, I run my wort through the chiller (a Duda Diesel large 40 plate) with a pump. I did gravity feed a few times, but then switched over to a pump and haven't looked back.

I think PJ is right. Self clean oven cycle thinking would turn everything not metal to ash. It's got to be hot enough, long enough. A call to Chirron might not be a bad idea.

I pressure cook mine for 15 min at 15psi. The pressure cooker will break down everything.

I might try the boil method, that sounds pretty easy. I usually did back flush it after every use, must have not done it enough. Should I try something like CLR or draino ?

No, I would not put draino in anything that was going to touch my beer. I say boil it and then run a strong acid cleaner through it. Next time dont bake the sugar in!!

What's wrong with drano? (Sodium Hydroxide)

Lots of bakers use it to make pretzels for instance. It's just a caustic mineral and in weak dilution is not harmful any more than phosphoric acid is. (used in sodas, and MANY other products, including treating beer water.)

For real? Just sounds crazy i guess. I would still start with boiling it imo.

Hmm... This is exactly why I can't see myself ever going to one of these.
I'm paranoid about what I can't see in there.

i use a plate chiller using a pump to start the siphon then gravity the rest of the way. plate chillers might be the most efficient way to chill any liquid (which is why commercial breweries use them) but you really have to be good about flushing and back flushing after each use, i pump boiling water through mine for 5-10 minutes. the only way i can imagine a severe clogging is not flushing and back flushing. baking it might kick it up a notch i suppose if there was wort inside. the pressure cooker seems like the best idea to me but who has a pressure cooker that big at home who isn't a canner?
