Csn you remove trap where lint filter goes - LG DLE5001W Dryer

Washing machines vary by manufacturers and models and some don't have a lint trap. Lint pumps out of the washer with the water, during the drain and spin cycle, and goes down the drain.

Have you cleaned the sensor bar? Did you remove the grates and clean out the lint traps, not the filter the actual traps? Does it have any codes stored? Most modern dryers can give error codes (even ones without a display)

Unplug it overnight. That will definitely reset it. Did you remove the cover where e the lint filter goes in. It is usually held in by two screws from the inside. There should be two wires leading to two metal strip on that cover. Make sure they are clean. You can also reach down into the lint trap to remove any more lint.

We have the same model and experience the same thing. The way I fix it is to remove the filter, then with a flash light I look down into the lint trap. You will notice that lint has built up in the track where the lint filter sits. I use a wooden skewer to run along the track and lift out the lent. Hope that helps

make sure that when you replace your filter that there is no obstruction in the filter thread(small stone), i have had many problems with this,if the drain light keeps comming on then check the waste pipe stand.

The pen has fallen into the blower housing and is hitting the fan blades.

Unplug the dryer!! Remove the two screws at the top of the lint trap. Remove the rear panel. Remove the four screws at the bottom that attach the lint filter housing to the blower housing. Then, remove the pen from the blower housing.

if it is a top lint filter take the lint filter out,turn dryer on,put your hand in it and you should feel a stong stuckion,if not remove the back panel and the 2 lint filter screws and check for clog-mike

you have to remove the top then the control pannel then the entire front. are you ready for this?

Hi,
To find the filter you need to do the following steps. Find your lint trap. Lint traps in washing machines can be in the agitator (the large plastic piece in the center of the tub), at the top of the washer on the rim of the tub, or attached to the washing machine's drainage hose. Pull out the agitator tube to check for the lint trap. Peel any loose lint from the filter. Scrub away lint that doesn't peel off easily with a heavy-duty paper towel or a wet sponge. Feel your way around the top rim of the washing machine's basin. If you locate a trap, pull it straight out of the machine. Peel away loose lint and follow up with a wet sponge or heavy-duty paper towel. Check your machine's drainage hose for an attached lint trap. Remove the trap and peel the top layer of lint off. Rinse the trap in low-pressure, warm water. Reattach to the drainage hose. Check for and remove any lint or debris that may have dropped into the washing machine basin during the cleaning.

It's an auto-clean internal lint filter. Lint is trapped from water circulating through the filter during the wash cycle. During the drain cycle it's backwashed and the lint goes down the drain.
