I have a cat30trbs with a refer. Ice box.when I pump the drain pedal water comes up in the sink and drains out slowly. My problem is that the refer. never completely drains. How can I get the excess fluid out? Thanks in advance.

You mean there's water in "trap" in the drain below the bottom of the cold-box; or, that there is fluid inside the box itself?

The water in the trap forms a "air block" that is useful in keeping the box "colder".

If the hose is full of "crud", then you can try to i) blow it out (best in reverse); and/or flushing it with some cleaner.

If the the issue is that the drain line is "too flat" below the fridge, you could try to create a "trap"
