Welcome to the forums! That should have made it one of the longer ribbons but those connections are very sensitive. If the lid was opened to the max or the ribbon disturbed during cleaning could throw it off. The lid open sensors are also as they do need to be and any small thing that gets trapped near the lid or sides of the front door can throw it. I even had a stiff latching mechanism on the front door throw it so just pushing it in the last millimeter settled the sensors.
Interestingly because it has a “Z” passage there is a bit of space between the door and the lid so if the exhaust is blocked or messed up that will be among the first places the smoke gets out.
If you still can’t fix the issue get photos as noted here and also close-ups of each end of the ribbon in the back so when Support gets to it they will have the data they need.
