Water in bottom of refrigerator under vegetable bins.

Maybe coming from the water filter. How old is the filter?

You gave no manufacturer name or model number so this is only a guess: If you refrigerator is a self defrosting one, it will periodically, allow ice building up in it to turn to water which naturally drips to the lowest point. Most refrigerators have a drain below the vegetable bins on the bottom. That is probably where the water is coming from. Solutions include putting a shallow baking pan under the bins or under the refrigerator to catch the water, then empty it periodically.

Hi,
Here is a tip that will tell you where the water is coming from and how to fix it. The drain hole has froze shut and the water from the defrost will not drain out.

The drain hole is inside the freezer. you have to take the back panel off to get to it and thaw/clean it out. if this drain stops up it will cause water to run down the back wall of the refrigerator down to the bottom. you can pull the refrigerator out from the wall and see the plastic tube coming from the back of the freezer.

WATER LEAKING FROM REFRIGERATOR OR INSIDE THE FREEZER OR FRESH FOOD SECTION
You have a blockage in your condensate defrost line or the pipe that fill the tray below the refrigerator is missing the condensate collector pan that uses the heat from the fan to evaporate the condensate back into the air inside your home.

Hi, The drain is plugged coming from the freezer section. Please get me a model# and I can assist you with this problem. Thanks Vic

If water appears on the floor in front of the refrigerator once or twice a day, it could be due to a clog in the defrost drain tube. The usual evidence of a clogged drain in a side-by-side refrigerator is ice under the bottom basket in the freezer compartment, in addition to a puddle of water on the floor.

Air flow ports adjusted correctly? Air flow fan running? I once had a bad temp sensor on the freezer coil that would not let the fan run.
