Temp Sensor Error on Ultimaker 2 Extended+

Hi,

i have the new Ultimaker and I want to look on the connection but I can't remove the two screws.

I hope this two screws are right?

Yes they are the screws to remove the main board cover.

When does the error occur? When you start a print as it's heating up?

To remove those screws, lift the bed up and use the screw driver/allen key on the top side, and hold the nuts in place on the bottom side (as in your picture)

Thanks, but i think there is a problem with the firmware. Sometimes before I start the print, I go directly to tune the nozzle temperature and the temperature standing on 0 degrees. After I change the temperature there is no problem.
