Washer will not drain:

Thedrain water pumpis the main part in your washing machine that pumps out the water. If this is defective or has failed in any way, this will be the reason why your washer will not drain the water. Before you order a new drain pump, make sure tocheck the pump to be sure a small object like clothing or similar has not lodged itself insideof it causing the NO DRAIN issue and even a no spin issue?. If the drain pump is not clogged, you can test it with a multimeter and remove and replace if needed. Go to Google or YouTube and search for "Replace Washing Machine Drain Pump" then type your brand and model number of washer to show you details on replacement.

The washing machinedrain hoseis where the water flows through to get the water out.If this drain hose is blocked, kinked, bent, or clogged, the washer will NOT be able to remove the waterfrom the tub. Check the drain hose to be sure it allows the water to flow freely. You can take the drain hose off and run water through it in your sink to be sure it is not blocked. If there is water STILL in the washer when you remove the drain hose, grab a bucket as the water will exit from where you disconnected it
Thewater pump belt(to drain out the water) may have broke or become frayed or loose.If this belt breaks then it is unable to drain and remove the water from your washer. Inspect the belt to see if this is causing theNO DRAINissue and remove and replace if needed.

If thelid switchis not working as required it will cause your washer to not drain (and many other problems).This may be unlikely as a bad lid switch will usually cause your washer to alsonot agitate or spin.However on some models this can vary. The best thing to do if you have a suspected bad lid switch is to test it. It can fail electrically and or mechanically. If mechanical failure is the issue, you should be able to see if it is cracked, broken, or not in place to make contact with the lid. To test it electrically, use a multimeter set on Ohms and test it for continuityMy advice is free cuz God is good!

hi Shellinator7.
check the small drain hose on the side of the pump that is clogged, then that is not a failure that will significantly affect the normal operation of the washer. If your washer is not draining okay and you don't mind catching some water that spills out of that pump filter area when you open it up, then you don't necessarily need to remove that front panel and bother with unclogging that small drain hose. If the large hose between the tub and the pump or the discharge hose between the pump and the house drain behind the washer is clogged, then you may need to open up that cabinet.

the pump should be easy to get from your appliance store if you bring the model number with you . Its a pretty common fault and repair part

Remove the dispenser drawer by pushing down on the tab at the center back and pulling drawer out. Now, remove the top of the fabric softener compartment and the parts of the soap dispenser and clean them all out. An old toothbrush often helps. Reassemble and replace. They should siphon out now.

If your washer won't drain, check these:

It spins, but doesn't pump 
It doesn't spin or pump
It pumps, but the water returns
It spins, but doesn't pump If your washer spins but doesn't pump the water out, the drain line is probably clogged. In many washers, a small sock or other piece of clothing can get between the clothes tub and the outer tub that holds the water. If the clothing gets between the tubs, it may then get into the drain hose that's attached to the pump--or even into the pump itself. If it's in the pump, you need to remove the hoses from the pump and pull the item out.

To remove the sock from the outer tub port, open the washer's main access panel and remove the large-diameter rubber hose that connects the pump to the bottom of the outer tub. Then, using needle-nose pliers, try to grab and remove the clothing through the port. 

Sometimes you can't remove the stuck clothing from below. Then you have to remove the agitator, top of the outer drum shield, and inner clothes tub. This isn't easy to do--and you may need special tools--so you might be happier getting a qualified appliance repair technician to do the job.

If the drain line isn't plugged, the problem may be with your pump. Even if the pump appears to be turning, the internal impeller may be broken. If so, you need to replace the pump.

It doesn't spin or pump If your washer doesn't spin or pump water out but the motor is running, your washer probably has a frozen pump pulley. If so, you need to replace the pump. To check the pulley, remove the pump from the washer and try to rotate the pulley manually. If it doesn't turn freely--if it's frozen or stiff--replace it. 

It pumps, but the water returns If the water that pumps out of the machine goes back into the machine after the spin cycle, your washer may be siphoning the water from a laundry tub that has a slow drain, back into the washer. The usual remedy for this is to improve the draining of the laundry tub. (Is something stuck in the drain?) Also, check for these problems:

• If the drain hose reaches more than about 4 inches into the laundry tub, cut off the excess.



• If your drain hose is lower than the washer's cabinet, install an air gap/siphon break assembly.

This is a problem with LG design. There are 2 problem areas that I have seen. One is that bottom on the rubber gasket and the other is in the filter drain pipe.

Beside throwing out the machine I believe you need to remove the rubber gasket and clean the mold from it, and also clean the filter drain pipe at the bottom.

I am not expert so I will let you know how this goes as I am trying it tonight. I just need to figure out to how to remove the rubber gasket .. as I see there is actually mold in there.
