Sorry to break it to you but the element may not be ok. I have done this on two occasions. Both were very brief, less than 5 minutes. Both times the elements were the ULWD incoloy elements that "resist dry firing". One time the elements were ok, the other time not. Unfortunately, I did not figure it out until the next brewday when I had 40 gallons of wort in the BK and only one of my two BK elements turned on. The element worked fine to heat my strike water but failed when I went to start my boil.
