This website is pretty helpful in repair tips. I agree it is likely a clogged drain line - you may try to find where it is supposed to drain into the pain and work backwards

If you are still under warranty, call Viking and report it. We had the 36" fridge/freezer and the drain line clogged consistently - so much so that they replaced the entire fridge.

Thanks for the responses. I am not in warranty. I would love to find where it drains into the pan, but it's a bit tight in there.
