Questions that only have an answer for the LG WashTower WKEX300HBA washer section

How do I tell if it's the washer or dryer at fault on my LG WashTower?+

Because the WashTower shares one control panel, note which drum the problem is in and which controls respond. Run each half on its own: start a short wash and, separately, a short dry, and watch which one shows the error or fails to start. A code on the shared display often has a washer or dryer prefix in the manual. Isolating the section first stops you troubleshooting the wrong machine.
