Odd, I've never had any of this. I think I've made a lot of different types of beer.

I have a 5500W ULWD "ripple" element in my BK. I don't do any cleaning other than hosing it after use. It gets 100% power until the boil, then about 75% duty.

Yes, I agree that it is the worts w/ greater percentages of protein that are the most problematic. I also guess that simply stirring the wort a few times while approaching boil might resuspend the trub enpough to alleiviate the issue. What I think bit my ass is the fact that I allowed the trub to settle around the element, and then refired the kettle without stirring.

Dumped 15 gallons

Noticeable burnt flavor...drinkable but would have made me nuts...the lost malt and hops I can handle, but all the wasted labor...I learned the downside of larger batch brewing but learned a lesson all the same.

I noticed that there is a very fine coating on the 2000w HWD elements I got from home depot. I used to scrub them with a green scrubbie after each batch. One day, I saw copper...next brew was a Rye IPA...elements scorched and couldnt be cleaned-beer was fine. Next elements I installed were still 2000w HWD, but I only clean them with a plastic bristled brush now. I also mounted the new elements rotated 90 degrees from how they are in this pic which makes them much easier to clean. Mounted like this, I had no idea what was on the bottom after a brew.

I just got ready to start a brew and i noticed "flaking" on my element. I tried to chip off as much as possible but only 1/3 came off. 30 Min PBW boil of 5 gallons just cleaned the kettle. Have 7 Gallon PhosAcid boiling right now hoping to get it all off.

Had a late brew night Friday and didn't clean as well as i should. Not sure if its left over crud from a previous brew that got baked on Friday.

May have to eat a new element.

Suck.
