My fridge has the drain tube in the back but it doesn’t go anywhere all the water keeps going on floor

if there's ice on the freezer floor it's usually caused by a blocked drain,when the fridge goes into defrost a heater comes on and melts the ice off of the evaporator coil,under the coil there's a drain,this can get blocked,the water can't drain into the drain tube and the water leaks onto the freezer floor,next time send the brand name and model number.some machines newer bottom mount freezers you have to change the drain tube,if it's an older fridge this happens,you have to melt out the drain and clear the tube,i use a steamer to do this but you have to shut the fridge down,get at the drain melt it out with hair dryer then you can try a turkey baster to push water through the drain hose and see if it clears,sometimes you might have to remove the back bottom panel,find the drain tube and snake a plastic wire tie up into it to clear the junk in there.hope this helps.

Not usually, will have to thaw, then run pan of hot water through drai. Can pull lower vent cover off to make sure it runs into drain pan under fridge. Drain may look clean but tube may not be. Can take wire from hanger to clear as well.

i know this is late but there's a heater kit made for this 4202160 is part number,you remove the shelves,you can put a mark under the shelf arm on the far outside where the shelves hook on so you can put them back in the same spot,then remove the light cover,the two screws and metal cover and then pull the wall off and set it to the side ,the drain heater kit plugs into the wire harness,the heater will heat up and keep drain from freezing,you can slide the tube off,stick a screw driver in to hold it down to the floor so you don't burn your hand and blow hot air into it with hair dryer to melt out ice,keep heat on for like 20 to 30 seconds then cold air or remove heat you don't want to mess the hose up from overheating wait a bit and hit it again until you melt out the ice,then i use a long plastic wire tie to stick into drain hose to clean it out,some nasty stuff in there,i use a steamer to clean the line out and then i have a piece of 1/4 inch plastic water line to snake into the drain,if this is the first time this has happened you don't need the heater kit,just clean out the tube and metal drain trough,also clean the back of the top crisper drawer shelf,crumbs and stuff can get in between the back wall and the top shelf and then will fall into the drain,if you keep that area clean you won't have to many issues and keep the fridge a little warmer so it doesn't freeze up the water in the drain tube,put the drain tube back onto the trough and pour hot water into it,if it drains down you're done if it's still blocked get a turkey baster and push hot water down into the drain tube to clear it,if it still doesn't clear remove the bottom kick panel,you'll see the drain pan and look at it because you have to get it back the same way in the clips then you can see the drain tube,stick a plastic tie up in there to clean it,sometimes there could be dust or something in the drain pan,when the water hits it it can get into the bottom of tube and block it but i've only had to do that once,hope this helps you out.

Two possibilities:
1. A cracked plastic tube. These will leak whenever there's a call for water - either the chilled water dispenser, or re-filling the icemaker tray (two seperate tubes). Pay particular attention to anywhere the tubes are clamped to the chassis; anywhere they're routed near or under the refrigeration unit; and near the solenoid valve - especially if there's a tight loop in the tube there.
2. A bad (leaking) connection where one of the tubes exits the water valve. Again, these will leak whenever the valve is activated.

Those plastic tubes don't last forever. I've replaced many of them for the same symptoms. They're known to simply deteriorate with age.
Manuf's make good money selling replacement tubing kits.

CHECK AT THE BACK OF YOUR FRIDGE IF THE DRAIN PIPE IS STILL ON THE COMPRESSOR. ON TOP OF THE COMPRESSOR THERE IS A BUCKET WHERE THE WATER FROM THE DRAIN PIPE RUNS IN. THE HEAT OF THE COMPRESSOR CAUSES THE WATER TO EVAPORATE.

You have a clogged drain. If you have a top mounted freezer you might have the drain line on the outside of the fridge. Look for a tube that is thicker than the water intake line and goes from back of bottom of freezer down into the back of the unit to a drain pan. Remove that tube and take it outside and use your hose to shoot a stream of water to clean it out.
If you have a side by side fridge, your drain is still at the lowest point at the rear of your freezer. You may have to removed the rear wall of the freezer to get at it. Remove the back cover to get at the other end of the drain tube. It needs to be cleaned out also.

no water will be coming from that line it is going to be a blocked drain line or a rust hole under where you can't see

If there is no water on the floor, it would have to be that the water entering the washer is going through the drain tube because it is too low, or for some odd reason the drain pump could actually be running, pumping out the water as its entering the washer. If there is water on the floor, there could be a leak anywhere along the drain tubing, the drain pump itself, or even the drum/basket seal.

hi thanks for the question the drain from the freezer to the drain pan is clogged up now with these new fridges the drain hose goes between the outside and inside wall of the fridge so the only way to clear the drain is to shut the fridge down with the doors open to allow the ice to thaw buy yourself a small plastic hose from hardware store and after it has thawed go to the drain tube at the back near the drain tray and blow into the tube to clear this should solve your problem thanks the appliance doc

It is supposed to drain to a plastic tray under the fridge. There is usually not a lot of water that drips down there... and the water usually will evaporate before overflowing.
If the water is draining on the inside of the fridge, then the drain tube on the rear of the fridge might be clogged. You should be able to remove the tube fairly easily, and then see if you can blow air into it to see if its clogged. Sometimes it just gets clogged with dirt and dust. If the tube is clogged, and you cannot blow air through it, then see if you can get a small somewhat flexible wire and push it through the tube.
Hopefully it will make it all the way to the other side.
Hope this helps.
Good luck.
