I recently withdrew a large vegetable drawer from a nearly new Bosch refrigerator. As I did so, part of the left hand slider fell onto the floor.
SWMBO hadn't seen but nevertheless yelled at me to be more careful.
When I tried to fit it back, I couldn't. There was no way it can be fitted unless the section attached to the side of the fridge was first taken off.
It isn't screwed on. It appears to be jammed in from above. I couldn't shift it by hand. I reckon it needs a tap from below with a light hammer, taking care to protect the side.
Before doing so, I thought I had better ask my betters on this group.
