Hello, I’ve had an F12 for 3 weeks. The top had no problems. The last 3 or 4 times it didn’t go on. After I tried it several times the top had opened and closed … Now nothing goes on anymore, the flap is open at the back, the top is angled at the back and it stops like this! When reading out it does not recognize the position of the top. The engine runs from the top while operating. After a time it switches off and then comes in the display an error message Cover in color red that this can neither be opened nor closed….. Who can help me, am grateful for any help.
