Our Samsung Fridge Freezer model RSH1DBRS is leaking water into the bottom of the fridge area - we have tried defrosting but it is still leaking - anything we can do?

This is caused by a blocked defrost drain. The cold air for the fridge is vented from the evaporator behind the freezer. Once every 24 hours the defrost timer, stops the compressor and applies power to a heater at the freezer evaporator coils. The defrosted water drips and runs to a drain normally into a metal tray on the compressor where it evaporates. On my GE fridge freezer there is a hose and a small p-trap at the rear. Easy to remove, soak in bleach and hot water and then flush through. Help for Samsung drains in the link.

Freezer /fridge water/ice in fridge and or freezer

Usually due to CONDENSATION due to bad door seals or a plugged evaporator drain line? Can use a soft flexable tubing and very hot water to clean it out. Bad door seals usually need replacement, but u can use a blow dryer and something to pry it closer to the door wall while blowing hot air on to it. To create a seal, to test for bad door seals place a dollar bill in between the door and wall of fridge where it closes. Then slide out the dollar bill with door closed. It should offer some resistance and not be easy to pull out.
Most all fridges have a drain. Look inside your fridge for a "V" shaped channel with a small hole. This hole leads to a tube and a small pan which sits on top of your refrigerator's compressor. The defrost cycle causes water to run into the channel, down the tube, and then it generally evaporates with the heat of the hot condenser/compressor.
However, if that tube is clogged with food crumbs, particles , debris etc, you will have to clear it to get back to a normal mode of operation. A toothpick, pipecleaner, straw or a cotton bud can often do the trick.
Even a frost free freezer will still ice up at times in the areas away from the heated defrost area and the drain line can freeze. This icing causes the pipe work to the compressor to ice over or sweat and cause a puddle. Or if the drainage has frozen over, it will need to be de-iced. ( usually the line is under the freezer bottom plate covering. Towards the back of the unit) And there is another inside the fridge area also.
Give the freezer a good overnight defrost until it's totally clear of ice in addition to making sure the drain is clear to the pan at the back and then restart the freezer.

We had the same fault on our Samsung American style RSH1DBRS fridge freezer as lots of other people seem to be having. After doing lots of research, we found the best solution seemed to be to buy a repair kit from Appliance DIY Repairs. The instructions were fantastic and the installation was a doddle. Excellent service & well priced.

Sounds to me you are having a ice blockage and or defrost problem. When that happens water can not get outside of the refrigerator. If you look inside the rear of freezer you may see a frost line or layer building on rear panel. You may just need to begin manual defrost until we can get a look at the evaporator coils and condensate collection tray. Unplug and begin and let me know your model number. I can help if you like, Sea Breeze

I HAVE HAD THE SAME PROBLEMS WITH THIS FRIDGE FREEZER-THE ENGINEER WHO CAME TO FIX IT SAID THAT SAMSUNG STOPPED MAKING THIS MODEL BECAUSE OF THE PROBLEMS WITH IT- THE ENGINEER REPAIRED IT BY DEFROSTING IT WITH A WALLPAPER STREAMER AND ALSO SAID HE CUT OFF A PIECE OF THE RUBBER TUBING WHICH CARRIES THE WATER THROUGH THE DRAINAGE SYSTEM BUT HE COULDN'T TELL ME WHY IT DID THIS IN THE FIRST PLACE

3 common refrigerator problems you can easily fix yourself

The freezer drain hose will drain the defrost water into a drip pan at the bottom of the freezer. When this pan becomes full, it will leak water onto the floor. This is a regular maintenance task whenever the freezer defrosts. Empty the drip pan during the defrost cycle.
How to Fix Water Leaking From the Bottom of Freezer

Why is my fridge leaking water on the floor? If the refrigerator is leaking water it's possible that the refrigerator has a clogged or freezing defrost drain. If the defrost drain freezes the defrost water will overflow the drain and drip down to the bottom of the compartment, If enough water accumulates in the bottom it can run out onto the floor.
SOLVED Water leak in refrigerator Refrigerator

We were able to fix the freezer water leak. We unscrewed the false freezer floor and the inside back panel. Ice had accumulated on the freezer floor and the defrosting drain was frozen. We removed the ice by using a blow dryer then poured boiling hot water onto the frozen drain hole. The frozen water in the drain pipe hole eventually melted and the water released into the defrosting drip pan at the bottom of the refrigerator. Problem solved. We no longer have water leaking into the refrigerator.

Sounds like the drain for the defrost cycle water may be plugged and you eventually overflow water. See if you can find the little drain hole for the coil defrost water and check for dirty/plugged. Try to pour hot water in the drain area and see if it runs out the drain fast (if real slow it's a problem). Make sure the water is also going down to the holding pan near the bottom area/compressor area (that's where it evaporates later). Let me know what you find.
