What is the heater element resistance spec for the DEE/4-20? I measured 11.8 ohms, is this acceptable?

Rated voltage and phasing would’ve helped.  Given it’s a 40a breaker, I guessed that it’s a 208v or 240v kettle connected for three phase by using this chart from the operators manual:

Here’s a copy of that manual:

By doing some math using the 208v specs, the elements calculated to be 11.8 ohms.

 

That doesn’t mean all is rosy with the element.  Did you check them to ground? 

 

I’m not overly familiar with that particular kettle, but I AM of Groen’s competitor – Cleveland.  Cleveland’s equivalent kettles had problems with the wiring harness that routed through the trunnion eventually abrading through the wire insulation and would short or develop an open wire or two.

 

SO…take some better readings of those elements and also the wiring harness.
