My money would be on a electrical problem. Power dropping through a long lead getting hot or faulty power controller or element or the like, maybe even power drop from something else turning on during the run. Less power would equal lower output and lower% from less reflux?

Has anyone had this happen? What is the cause? what is the solution? Again the distillate flow rate over the course of several hours reduced.

Yesterday I did a spirit run of CFW. Using 4 plates. To get up to temp I was using 2 x 2400 watts elements, no controller. With both elements on it was easy for the distillate to push through. I turned off 1 element and adjusted the RCr. I noticed when in the 3rd or 4th jar, the abv was dropping. I also noticed that the 3rd plate wasn't loaded ant more - but the 1st, 2nd and 4th plates were very active. Has anyone had this happen? What is the cause? what is the solution? Again the distillate flow rate over the course of several hours reduced.
PeterC wrote:I had an issue with some plates loading and others were not and it came down to bypassing. The returned alcohol ran past the plate because it was not sealed correctly. I could see it running down the sidewalls. Suggest that you reset the third plate. Lots of power can overcome some slight bypassing but it is not the right fix.
