Well, it depends on the model, I looked the digital pressure cooker manual (found here http://www.hippressurecooking.com/category/manuals/cooks-essentials/) E4 is a Signal Switch Malfunction. The recommend turning off and un-plugging the pressure cooker and letting it cool of completely before trying to use it again.
