Safety first
Stop the washer for a water leak, burning smell, damaged cord, exposed electrical part or violent movement. Disconnect power only when safe; turn off the water taps for leaks. Never defeat a lid or door lock, reach into a moving tub or remove electrical covers. Drain or hose work can release water; use the exact LG owner manual and qualified service when required.
Quick help
| What you see | Safe next step | When to request service |
|---|---|---|
| Washer will not fill | Check that the external taps are open and that visible inlet hoses are not bent. | Leaks, damaged hoses or continued failed filling. |
| Spin is noisy or load stays wet | Pause safely, redistribute laundry once the lid/door unlocks, and check for an uneven load. | Hard impact noise, movement across the floor, or repeated failure. |
| Water remains in the tub | Check only that the accessible drain hose is not crushed; do not open any pump or electrical cover. | Water leaking, trapped water or repeated draining failures. |
Before trying a control or cleaning procedure: match the complete rating-label model, suffix and manual. These are basic external checks, not confirmed model-specific diagnosis or code-reset instructions.
Error codes and display messages
Evidence limit: LG publishes the following for its U.S. front-load washer family, but the reviewed online support listings have not established that each code appears on WM9901HBA with its particular production suffix. Every family shown below is not confirmed for this exact model and is omitted from the importer Error Codes records. Lack of confirmation does not prove a code cannot appear.
| Display family | Meaning in cited LG general guidance | Source / model status |
|---|---|---|
| IE | Water-supply / filling problem | General LG U.S. front-load guidance; not confirmed for WM9901HBA |
| UE / Ub | Laundry-load imbalance | General LG U.S. front-load guidance; not confirmed for WM9901HBA |
| OE | Water did not drain as expected | General LG U.S. front-load guidance; not confirmed for WM9901HBA |
| dE1 | Door is open or not properly closed | General LG U.S. front-load guidance; not confirmed for WM9901HBA |
LG warns that notifications can vary by model. If a message appears, photograph the whole screen and cross-check it against the model-and-suffix-matched owner documentation. Do not use a button sequence from a different LG washer.
Common problems
ezDispense or touchscreen settings are unclear: Confirm the active setting on the 7-inch touch display; LG confirms automatic dosing but the exact wash-cycle/dosing instructions must come from the listed WM9901HBA manual. Stop: Seek service for an unresponsive screen, leakage or dispensing that continues unexpectedly.
Filling: If no water enters, inspect external tap positions and hose routing before consulting LG general inlet guidance. If the unit leaks or the hose is damaged, do not keep running it.
Unbalanced spin: Once the lid or door is unlocked, check that the load is not bunched on one side. LG provides general balance checks. Continual large movement or loud impact noise calls for service.
Drainage: Look only for an obvious external drain-hose obstruction. Internal pump-filter access or disassembly must be checked against the proper owner guide and is not prescribed here.
