The refrigerator leaks water inside itself from the freezer to the fridge. After a few days it pools on the bottom of the fridge. Wish I can send videos, its a pretty fast paced leak and happens occasionally
I'm voting for auto defrost freezer with obstructed drain too, but more specifically I'm guessing the drain is blocked by ice. Mine has the freezer on bottom, so when its drain becomes blocked with ice (has happened 3 times now) I get a sudden pool of water on the kitchen floor rather than dripping down into the refrigerator.
Really the only way to check whether this is happening is to disassemble the freezer compartment and visually check.
Remove the food from the freezer compartment. Have a look at its rear wall. There's likely to be a panel with louvers, or a gap around the edges, and held in place by several screws. Remove the screws and gently wiggle the panel out. There might be a foam seal, and it may be stuck in place with a little (or a lot?) of ice. You'll also want to take care to avoid damaging the fins on the heat exchanger (or cutting your finger on them; they can be sharp!).
What you find behind that cover panel might look something like the photo below (credit: www.indiamart.com). There's likely to be some kind of sloped drainage pan with a port at the low point. Is there an accumulation of ice in the area?
I do not know this particular refrigerator but most of the time when this happens the solution is relatively easy to resolve. The hardest part is to first find the drain. Once you find it flush it out with hot water using a turkey baster. Caution it is clogged with ice so it may take a few minutes to be effective. Do not use to much water or it will be on the floor. once you have it open use your shop vac to suck out any food or other debris that may be in there. Now enjoy a dripless refrigerator for a while, probably lots of years.
