LG washer/dryer combo WM3455HS not drying

[expatriot98]

I just bought a used LG WM3455HS from a private party. The machine washes great and will dry the clothes to a damp state, but not to fully dry. In some googling, I've read that lint may be collecting in a tube or duct and hinders or stops the drying process completly. A service call is required where a tech digs into the works of the machine to clean out the lint. I have not been able to find any DIY's for this process or even where this collection point is located. Any hints from the experts would be greatly appreciated. I have done some washer repair before (Neptune bearings) so not afraid to dig in.

Thanks,
Mark

Looks like I got the model wrong. It is a WM3431HS instead of a 3455. thx

The best thing to do is take the dryer vent off back of dryer, see if it drys better.

Even though ventless , there is a "dry vent" assembly with dry fan at top . There will be a clog of lint midway in plastic vent . Take off back of machine, take off top of machine, unscrew dry vent fan (white and in top corner of machine), unscrew bottom of white plastic vent 5 screws, I used wire hanger from top to push clog to bottom, then used fingers to pull out. Yuck.

When this problem arises, AIRFLOW is the issue. I remove the top and rear panel. The dryer and its venting system is slightly like a puzzle. Removing the large tube that runs from the top to bottom and washing out FULLY with a garden hose will resolve the problem. Be prepared, when it gets to the state of not drying fully, there will be mucho linto.... As a curiosity, inspect where the dryer casing (BROWN) makes a 180 degree turn into the top of the front outer tub... I've seen airflow so inhibited that it melted the tub!!!!(Directly underneath) Let me know if i could be of more assistance.
