Drain pipe under eaves on second story

This is because that loop of drain previously was keeping the water from draining. Try tying the hose to the back of the unit and then down to the pipe under the sink. Like an upside down "U"

try by taking of the trap under sink, and clearing it out ! its the U shaped pipe under sink drain. this is where most of the sinks plug up. unless you have a plugged up drain pipe. do the drain trap first. if this does not solve all of problem, put some good drain cleaner down sink drain. good-day ! and have a merry christmas.

I assume it is dripping water when the AC is running. If you look at the attic unit, there should be a PVC pipe running from the unit - probably an insulated PVC pipe. This pipe probably goes across the attic to the edge of the house and drains outside. The drain pan may also have a drain pipe, but the one on the AC unit is the issue, and is probably plugged. Go outside and see if you can locate the AC drain pipe. See if the ground is wet below the pipe and if water is steadily dripping from the pipe (with AC running). If the pipe and ground are dry, the pipe is plugged. If you have a wet/dry vac, try connecting it to the drain pipe outside to see if you can **** the pluggage out. If you can get it clear, water should start dripping out of the pipe. This same thing happened at our house. I decided to cut the pipe in the attic, and add in a PVC isolation valve, tee, and water hose connection with plug, so I can valve out the AC unit from the pipe, remove hose connection plug, and hook up a water hose and flush the line to outside. Lowe's sells all of the PVC pipe fittings. The water pressure from the hose will always flush out the algae and crud to the outside of the house. I can also remove the plug and pour a cup of bleach down the drain pipe every couple of months to keep algae growth in check. I also cut out the trap (u-leg) from pipe in the attic and purchased a ready made trap a Lowes (the contractor who built our house had made a lousy homemade trap). I purchased a few PVC elbows and installed the trap on the drain pipe outside. By the way, our AC drain pipe comes out of our wall outside and drains near our outside unit. Our secondary drain pan drain pipe comes out outside from an eave on the side of the house. I don't know what you drain line looks like (it may have a port to add bleach, or some cleanout provisions, maybe not). If you choose to modify/improve it, then make a sketch of it, go to Lowe's and get the PVC parts you need + PVC pipe primer and cement. PVC cement dries fast. Remember, the pipe must flow downhill from you AC attic unit. You can use a regular wood saw to cut the pipe. I hope this helps you. You need to keep the drain line clear as algae will continue to grow in it. Pouring bleach in the line every month or two helps. You also need to check maybe once a month that the line is draining properly (check to see if dripping outside). You can get some serious water damage to your ceilings if the water backs up and overflows. I discovered that our drain line was plugged just in time as our drain pan drain line was also partially plugged and drain pan was about to overflow.

When your refer defrosts a couple times a day it produces about a quarter of a cup of water each time.This occurs in the freezer section.The water travels down a drain pipe (or tube) that leads to a drian pan in the bottom of the unit. It is collected and evaporates from the heat of the motor.
If the drain is plugged water will form inside the unit itself.If the drain tube has somehow moved and not allowing the water to collect in the drain pan it will go on the floor.Either way,if the drain is the problem the amount of water should be pretty small, no more than a cup or two.If you have an icemaker or ice and water through the door and the amount of water on the floor is more than a cup or two. I would find the water shutoff for the supply line(probably behind the unit in newer homes)and turn it off.Clean up the water and wait a day.If the water goes away assume that one of the plastic lines in the unit that carries water to the icemaker or door is leaking.If the water continues I would suspect the drain.The only way to check the drain is to unplug the unit and remove the cardboard back,locate the drain pan and see if water is present and that the drain line is in it's proper place.
If one of the water lines is leaking you will most likely need a service tech.
Also it's best to turn the icemaker off by lifting the arm or switch before you turn the water off for testing.

sounds like the overflow drain is picking up the water that means the main drain is clogged.you need to find the main drain pipe if lookin at the air handler in attic there should be 2 drains from unit one higher than other follow it and blow out drain they put the other overflow drain out the eve so if it stars leaking someone notices it and it doesnt damage cieling but it sound like it needs imediate attention befor it does go to the overflow pan and damage your cieling. i hope this helps and good luck

Are you taking an “ND” error to the display? Good job on checking for the clog from the sump cap to the input to the drain pump and out the drain pump to the drain pipe. The sump cap is sort of semi transparent if you shine a flash light on it do you see any restrictions? I had half of a bank card stuck in mine. This the sump cap item 9 of the parts view.

Drain Pump opened up;


I would try to turn on the drain pump in service mode and see if you hear it spin up. I guess the impeller could be jammed up. So let’s try that first. I post these links constantly for support so disregard if you have them. Link to Service Manual for reference. Sears Parts Direct for reference.
I would go to page 16 of the SM lower right hand part of page, Board Output Test and turn on the drain pump in service mode and see if the motor runs. Here is the test; close the lid and enter the Service Mode by pressing and holding the Enviro Plus and Spin Only keys for three seconds or the display reads “00”
Pressing the Delicates key will lock the lid. Now press the Presoak key the drain pump will turn on do you hear it run? Stop the test as the SM states with off button or hit the Presoak key. If the drain pumps sounds like it turns on I would put in a bucket of water in the wash basket and see how the output stream looks out of the drain hose when you turn on the Drain Pump in service mode. I get about a 2.5" vertical lift of the output stream from the drain pump.

Post back for questions or any help we can provide. Rich

yes, that is your emergency drain pipe. You need to have the a/c drained cleaned out. It is probably jammed up with algea. A professional should be called to blow it out. or get ahold of your Mr. Fixit buddy. If you leave it like this your drain pan will eventually rust out and cause major interior damage to your home.

Solved by draining water from bottom pan.

I had same problem twice, the first time there was a sock in the filter at the front adjoining the pump, the second time a sock had got in the pipe under the drum which is more awkward to get to but is possible if you have the tools to remove the back plate and are ok at diy, there is a spring tension clip on the pipe which comes off quite easily with a pair of pliers.
