There is a smell coming. There is a smell coming from my KitchenAid Superba refrigerator and it

Question

There is a smell coming from my KitchenAid Superba refrigerator and it smells like glue. I've changed the filter and the ice maker was replaced because it stopped working. We thought it was the motor in the ice maker that caused the smell, but now that it is replaced, it is worse. The water is even worse than it was before - it smells like glue. Do you know what it could be? I've cleaned everything out of the frig. It is cooling ok, no problems there.
