Refrigerator Leaking inside

I have been finding lots of water on the bottom of the fridge or in the bottom drawer.

Today I was getting water from the door and heard water spraying. Took the bins out and when I get water from the door it sprays from the back from a stomach looking thing. There is a tube with a blue fitting.

And, The water in the door doesn’t always work. That may be another issue. I thought it froze. Just wanted to mention.

I have a Whirlpool WSF26C2EXF01. I have a video of what happens but can’t figure out how to attach.

Is this the part?

It holds the cold water for the front dispenser. If it gets too cold it can freeze and crack. Does any of your fresh food freeze too?
