I unscrewed the lower panel on the front and cleaned out the large black round cap on my LG Tromm Washer. I blow thru the small rubber hose and it sounds clear. I am still getting the OE when getting to the rinse/spin cycle.

Get some towels ready for the floor'

Open the small door on the left side bottom
Unscrew the large black cap pull out and clean filter

that's draining error. check the filter cleanout behind lower left panel on front of machine; of course drain 1st via small drain hose. if thats o.k the drain pump itself may be jammed with debris or the drain hose could be clogged.

Is it pumping out water,im guessing not! OE outlet error.The pump impellor might be jambed with a hair pin or nail.if not,the pump may just be stuffed & impellor not turning & not pumping water out.Im presuming its not pumping water out on any part of the cycles at all.Also make sure you havnt attached extra hose to the the drain hose to water your garden,these pumps are weak.hope i helped.

on the front lower left there is a panel. Pry it open from the top. Unscrew the large black round cap. Be prepared for water to rush out. There is a trap to clean out. To the left there is a rubber hose with a plug in the end. Remove plug and see if hose is clogged. Clean it out. Replace and it should run. If not, try blowing through the discharge hose in the back to make sure all is clear. If not??

Part of the problem is that your filter is clogged. Remove the front bottom panel by unscrewing 3 small screws at the base. At the lower right, there is a filter cap that you need to unscrew by hand. Be sure to put a small pail before you unscrew it because a lot of water will come out. Then clean the filter and screw it back in.

In terms of the leaking, that started with my washer just recently. It's not the filter....think it's the rubber seal in the front. If you pull back the rubber, there are small drainage holes that can get clogged. Cleaning helps, but doesn't solve it.

There is a small panel on the bottom left front of the washer with a tab on the top middle holding it onto the front of the washer. depress this tab with a small flathead screwdriver and the panel will open downward. You will now see a small round black piece on the left with a flat screw head on it, about an inch in diameter. unscrew this about a quarter of a turn and it will come out with a small hose attached. This is connected to the drain pump. Have a shop vac ready, pull the black plug out of the hose and this will drain the pump. The larger round piece on the right, about 3 inches in diameter is your drain pump. After draining all the water unscrew it with your hand. When you get this out it will have a screen attached which needs to be cleaned at least once a year.
Please rate this post. Thank You.

On the front bottom left is a small access paner about 5 x3 1/2 in. Gently pop it open from the top. Tou will see a black drain hose with a plug in the end. Place a pan on the floor and remove the plug and drain the resudial water from the machine until it stops. Then, unscrew the filter in the same opening counter clockwise to remove it. Clean and replace in the reverse order installing plug in hose and do not over tighten filter. Run a load and check for leaks and replace panel.

Yes there is a filter, it can be found in one of two locations.
check to see if there is a removable plastic trim at the front of the washer, if there is then the filter could be located there..
It has a round black cover, which you unscrew anti clockwise to remove.
If no filter located there, then you need to remove lower rear cover of washer, locate large black hose on right, and undo clip and remove hose, be careful because there will be water in it.

Remove plastic filter and ball, clean and replace, making sure you refit hose securely.

Test for leaks before refitting panel.
Plz rate my solution.
Thanks.

oe is an error code for pump problem disconnect power cord open small door on lower front of cabinet pull little tube out and plug from tube and drain water in to bucket after water is drained unscrew cap of pump to clear out any obstructions reinstall the cap and plug and give a test run

Bent pinched or clooged drain hose. Other cause may be the drain filter in the front of the machine. (The small door on the lower left of the machine) With a pan, remove the cap and drain water from the small tube. Then open the larger cap and clean out the lint. This should solve the problem.
