I bought this for a condo that could not accommodate an exterior vent. Most horrible appliance ever. Takes 4-6 hours to dry 1 load of 4 bath towels (to damp-dry not fully dry). Are you kidding me. I bought a rack and hang dried them out of frustration, then fluffed them in the dryer - they came out wetter than they went in!! Ran diagnostics, no errors. Called service and they found appliance to be in proper working order and informed me that it takes HOURS to dry proper size loads. And yes I used normal not “eco” dry - eco dry is measured in DAYS of drying. Weird part - 1st ever load 1.5 hours to dry, 2nd load  3 hours+, 3rd load and on 5 hours if ever. Hence service. And service worked with LG to let me know ^^^^^ that was all in correct working condition.
