GE Concept II fridge leaks inside fridge and then out to floor. Noticed that water is dripping in back under freezer where there is a cup-like part. What is the problem?

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.

There is hole behind the freezer panel that the water should drain thru . Use a small hose in the hole and blow thru to cleam drain .

I had the same problem & I had to clean the water collector at
the back inside the fridge. It was was plugged with residue draining from the freezer. Make sure you clean the drainage pipe behind the fridge also & run some water though the whole system to clean out.
No problems for me after that.

Something to try....on the back wall of the fridge nearer to the top is a little cup like part sticking out. There is water in it but it usually runs down an attached tube inside back wall and ends up under the fridge and gets evaporated. If that tube or the little cup thing is plugged then it will drip in the fridge and collect on the inside bottom of the fridge. So the trick is to clean them out. Check it out ...may solve the problem.

Most times this is a plugged defrost drain system. The defrost heater in the freezer section melts the frost and changes it to water, this water is suppose to flow down a drain system. If this drain system is restricted or plugged the water will leak inside the refrigerator. The drain system starts in the freezer section with a tray built under the evaporator coil. The water is funneled through a small hose into a cup in the top middle of the fresh food section ( not on all models, but this is the most common way ), from there, the water is directed out the back wall to a drain hose that runs down the back of the refrigerator into a condensing tray. The heat created under the fridge makes the water evaporate and disappear. Some of the cups ( in the top back of the fresh food section ) can be removed for cleaning. A turkey baster can be used to help clean out the drain system. Fill the baster with hot water and "blast" it into the drain hose to help flush it out. A piece of wire or pipe cleaner can also be pushed into the drain hoses to help clean then out. On a S x S style of fridge the drain system is in the bottom back of the freezer section and often you will have to remove the evaporator cover to access the drain hole. You can clean this out in the same manner as previously mentioned, but because of the water leaking into the freezer instead of the fresh food section you will have to remove the ice build up to clean out the drain system.


If in case the water is leaking on the floor then:--
There are several things to check for. The condensing defrost tray under the fridge can crack or develop a hole and leak onto the floor. A door gasket not closing properly may cause sweating and leak onto the floor. If your fridge has developed a frost free failure problem, often the frost will travel down the suction line at the back of the fridge and drip water on the floor. The heat exchanger tubing can separate and also sweat and drip on the floor. Ice maker and chilled water fill lines can crack and leak as well, this is fairly common with the plastic lines as they can dry out and crack.
Unplug the unit from main power outlet and empty whole unit and keep both the doors open and then connect the power after 24 hours and recheck.This procedure is called manual defrost reset.If this helps then its OK,but if this procedure not helping then its the faulty defrost unit and it needs to be replaced.

Well for one thing that unit was manufactured 10 years ago. But it sounds like the defrost drain is clogged and the water is running down the inside of the unit. The evaporator (not condenser) is on the bottom of the freezer compartment. The bottom panel of the freezer comes out. They are a bit of a pain to do, but can be done.

That water is coming from your freezer during the defrost cycle. Normally there is a drain in your freezer that goes to a cup in your refrigerator and through the back of your refrigerator through a drain tube which extends down to a drip pan. If this tube gets plugged up, water will overflow in the cup and leak at the back wall of your refrigerator and through the holes that lead to the crisper's floor area. If you can remove the cup and using a wire dislodge anything blocking the drain, clean the cup of any debris and check your freezer drain for any obstruction causing water backing up and leaking !

My Whirlpool fridge had water droplets falling onto all three shelves and pooling unter the crisper drawers. I solved the problem by clearing the ice-clogged drain in the freezer.

In Whirlpool model ET21UM, the condensation drain hole is located directly behind the freezer. To access the drain hole, remove all your frozen items and place them in a large picnic cooler. Notice that the floor of the freezer is basically a large plastic tray fastened by two small bolts. Unscrew the bolts with a wrench or ratchet and remove the plastic tray. At this point you will probably see that water has seeped under the tray and created a mini ice rink on the bottom of your freezer. You can tap the ice lightly with the handle of a screwdriver to break it up. Once it's broken, toss the ice into your sink, or put it in a plastic bag and store into your cooler to keep everything cold.

Once the ice has been removed from the freezer floor, you should be able to see a metal drip trough in the back under a false wall hiding the condenser coils. It's a little tougher to remove the ice from the drip trough with the screwdriver method, so you might want to use a hair dryer. After a few minutes with the hair dryer, you should be able to remove most of the ice by hand. You can remove any water with a sponge or turkey baster. The only ice left will be a plug of ice in the drain hole in the middle of the drip trough. Heat up a cup of water in the microwave and carefully pour it into the drip trough. If the drip trough is hard to access, you might need to use a funnel. The hot water should melt most of the ice in the drain hole. If it pools in the drip trough and doesn't drain, use a sponge or turkey baster to remove the water and add hot water again. A small length of wire or a pipe cleaner might help clear any other obstruction in the drain hole. When the drain is clear you should hear water flowing through it. Dry off the floor of the freezer and return the plastic floor tray to it's spot and fasten with the two bolts. Remove any water that has pooled in your refigerator and you're done.
