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: WM4500HBA
What that covers: LG front-load washer; ThinQ-enabled controls and menu paths vary by model.

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 & capacity: 5.0 cu. ft. mega-capacity FRONT-LOAD washer with a door gasket. On a drum this large, overloading is a common cause of unbalance, long rebalancing and poor rinsing — leave a hand's width of space at the top.
Motor — Direct Drive inverter (no belt): Belt-less Direct Drive inverter motor; noise/vibration is a bearing and load-balance question, not a belt.
Smart & wash features: TurboWash 360 fast wash and Wi-Fi (ThinQ). Gasket maintenance (wipe dry, door ajar, monthly Tub Clean) governs odour and mildew.

Exact questions

Questions that only have an answer for the LG WM4500HBA front-load washer

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.

My LG WM4500 shakes hard or walks during spin.+

The usual causes are load balance and installation. Distribute the load evenly (large single items like a comforter throw it off), confirm all four shipping bolts were removed at install (a very common miss that causes violent shaking), and check the machine is level with locked feet on a solid floor. Because LG uses a Direct Drive motor with no belt, persistent noise after those checks points at the drum bearings.
