Frequently asked questions

This error occurs because the cover sensor detects that the top door is either open or not fully latched shut.

No, it is a safety feature. It usually just requires a firm manual adjustment of the cover.

If labels are stuck near the hinge, the door will not close, triggering this error.

Keep the latch and the sensor area clean, and avoid slamming the door.
