tried to add photo?here is picture of front.
OK, worked...On the front, though, it flashed the number "20".No, its not a Men-In-Black memory neutralizer, its just the error code.The 'manufacturer' FAQ video indicates that the system is designed to not start boiling, unless the interlock for the pressure is in place.Most likely, is that the locking mechanism is stuck, or broken.This is the 2nd place to check after the "seal" portion on the edge.
