[QUOTE="Agentgonzo, post: 1138730, member: 43016"] I would definitely contact GF and see what they say. As a question, how clean is your bottom plate? A lot of heater elements have safety cutouts in the element themselves to prevent burnout. I don't understand the exact mechanics of how it works, but if the element gets too hot, it cuts out. If there is too much build-up of 'old crud' on the heating element, then the following happens: [LIST] [*]The crud insulates the heating element from the wort [*]That stops the heating element from putting its heat into the wort as quickly as it should [*]That means the heating element gets hotter than it normally would [*]The thermal cutout kicks in to prevent the heating element damaging itself. [/LIST] I'm only on about 10 brews so far on my GF, so haven't had any problems with it, but my old plastic kettle that had a standard element in the bottom would suffer from this if I didn't clean it enough (especially after dark brews). It would cut out frequently, then restart, going from about 97 degrees, back to boiling, then click off and drop again. It was never as bad as you're seeing, but maybe the GF cutouts are more sensitive? Anyway, I'm not questioning setup, just sharing experience in case it helps. I've noticed buildup of 'crud' on the element on the bottom of my GF and so before the next brew, I'm gonna get some descaler/barkeep's friend on it and get it back to new. [/QUOTE]
