The bottom part of the door (with butt hinges) doesn't close at all, preventing door closure. I have tried taking out the metal sockets into which the sliding parts enter, nothing changed, and it remains exact same amount of open. Another symptom, if it matters, on an open-door mode - the upper part opens too (the mode where only upper part is lowered inwards as to not open the whole door/window, but get some air in). What could I do?
Sounds like the hinge is slightly bent. If this is the case you will need a new butt hinge. Note - Hinges can get bent in a number of different ways. Most common way is if a stone gets lodged on the frame on hinge side and someone than closes the door. Or on an open out door if the wind catches it and bangs the door leaf of the cement reveal. Also another way is people running an electric cable out the door on the hinge side for outdoor Christmas lights.
