Water in the fridge? "Dry the fridge"
Some time ago, I made myself a new built-in refrigerator and after a few weeks with horror found that some water collected in the lower area.
Since I had no desire for the theater with the return and installation and removal, I tried out, if possibly a small container of moisture-absorbent granules eliminated the problem and behold, my fridge is dry.
Have at a well-known discount store, A is the first letter, bought a so-called Raumentfeuchterset Mini and I am very satisfied. Have passed this tip in the circle of acquaintances and two other users with the same problem are also convinced.
I have placed the container in the top compartment, after about 1 year, a new bag must be inserted and now and then the collected water to be emptied.
Good luck and success!
