Klaudio KD-CLN-LP200 Owners

I recently purchased a used LP 200 and it makes a loud bubbling/gurgling sound during the cleaning cycle. Of the Youtube videos I've seen, they don't exhibit this. I contacted the owner and he claims it's always ben like that. Also, during the cleaning cycle, I don't see much water on the record. 

Here's a video I uploaded on Youtube. I'm curious to know if his is the normal sound. Thank you.
