What to do for Error code 4000?
FAQ ID -9071

Identify and make a note of the axis in error (e.g., Error 4000 axis 3). Check the worktable and the centrifuge for obstructions. Make sure that the correct plasticware is used. Check that all plasticware is loaded in the correct positions and is seated firmly.

 

Power off the QIAcube and carefully pull the robotic arm forward. Check the tip disposal slot is not blocked. Make sure that a disposable tip is not stuck to the tip adapter or that a spin-column or microcentrifuge tube is not stuck to the robotic gripper. If an item is stuck, reinitialize the QIAcube.
