So I recently received my Joule last week. I was able to use it fine the first time and made some chicken breasts. Today, however, I'm trying to heat up and get ready to cook and the Joule won't heat up the water. The water is above the minimum line, everything is clean and setup. I left it for an hour and the water just dropped from 89F to 84F with no signs of getting hotter. We tried a factory reset but that also didn't work. I'm not sure what to do.
