I came home today to a terrible smell coming from the back of my fridge. I moved it forward and looked at the back and found the smell coming from a plastic container connected to near the bottom of the fridge. The container has this yellow stuff with black bits congealed at its surface and is filled with a liquid. The manual to the fridge says whatever is in there is meant to evaporate by its self. I have tried removing the container but it appears to be fixed in or I just don’t know how to. The fridge is a Bosch exxcel under the counter type fridge. If anyone knows what I should do or what the problem is I would greatly appreciate any help you can provide.
