Confirm the model first

Which units this covers, and how to tell yours is one of them

Every answer below is scoped to these model identifiers. A neighbouring model in the same line can use a different part, a different reset sequence or a different radio, so matching the identifier before following a procedure is the step that decides whether the rest of the page applies to you.

Model numbers and patterns: WKEX300H*
What that covers: WashTower model with center controls; confirm washer versus dryer status.

Published specification

What is true of this model and changes how you fix it

These are the properties that decide which procedure applies. Each is read from the manufacturer’s own published figures for this model, not carried over from a sibling that shares its retail name.

Type — WashTower: stacked washer + dryer, one control panel: A larger-capacity WashTower with the washer below, dryer above, and ONE shared center control panel. As with any WashTower, a control/power fault can affect both halves together, and a centrally shown code may belong to either section — determine washer-versus-dryer first.
Motor — Direct Drive inverter (no belt): Belt-less Direct Drive inverter washer motor; noise/vibration is bearings and balance, not a belt.
Smart: ThinQ Wi-Fi with AI-sensing. Washer front-load gasket care for odour; the dryer needs normal lint/vent maintenance.

Exact questions

Questions that only have an answer for the LG WashTower WKEX300H washer section

Each answer below uses this model’s own published figures. The same question asked about a different model in the line has a different answer, which is why it is answered here rather than on a general page.

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.

Structured depth, not empty permutations
