Brewed for the first time with my 120v 2000w electric HLT last weekend. However, there was rust completely covering the threads of the element and locknut, and it dripped onto the kettle and made a little rust puddle about 3" wide.
I thought surely it was the element (stainless) threads but the rust wiped right off. Had to really scrub the locknut though. Also, the element developed a lot of calcium precipitate on it.
I get out the Barkeeps Friend and really worked the threads and locknut, let it sit 30 minutes, then rinsed it well. Hoping the steel passivates.
Anyone else experience this with Rheem element or locknut from Bargain Fittings?
