It seems to me that a part has gone missing but I can’t quite find out what part it is.
The water is feeding up through the black pipe and into water container, but not all of it. The problem is that the drawer is flooding. It’s like a seal is missing or similar. Some water will reach the container, some will miss the hole and collect in the drawer.
This is the water container:

This is what the dryer looks like from the inside with the the pipe coming in. The water is dropped into the container, from the pipe, most misses.

What is the part that’s missing?
