I have a concealed element. I assume the dry boil protection kicks in and turns off the element when there is crud baked onto the element cover.
As Ian H says a quick scrape and it doesnt cut out.
Cheers.
I have the same issue when the mash crud starts to bake onto the element(occasionally), a quick scrape with my brew spoon and it fires up again.
Not a huge issue, just a pain.
