Hello everyone.
Today I transported my Nadesico Pachinko machine to a small matsuri nearby, and for some reason the machine won't stop flashing error lights and tells me that the door is open, however we have opened and closed the door multiple times to no avail.
We've even tried turning it on and off and attempting to reset multiple times.

This is the first time I've ever had this problem, and I honestly have no idea what to do. Any help would be much appreciated C:
