Not so easy, pull your refrigerator out and look for water, and on the wall behind.

Hoses from wall valves to where ever.

Worse scenario - I won't go there. If you can't find it, call a plumber. Water can do a lot of damage in a hurry. Mitigate

Water will travel downhill (might not seem like downhill), but can then show-up 5 or 20 feet away. This is very common with many floor coverings.

Laundry room - leaking washer, or faucets on the wall behind. Could also be a clogged laundry drain that only pukes when pumping out the tub.

I lay down paper towels under sinks and toilets. Anything leaking or dripping show right up. My guess dish washer?
