Model-Specific Repair Notes
The LG WM8100HVA should always be matched by the full model tag before ordering parts.

That is why the safest workflow is to confirm the symptom, inspect the most likely category first, and then match the exact replacement to the full model number.
FAQ
Does LG WM8100HVA drain pump replacement always mean one part is bad?
No. Even on the same model, the same symptom can be caused by more than one failure point. That is why the basic checks above matter before ordering parts.

Only after ruling out the simplest causes. For example, a drain problem should be checked for hose and filter blockage before replacing the pump, and a dryer heat problem should be checked for airflow restriction before replacing heat parts.

It is best used as a troubleshooting guide for this model family, but exact replacement parts should always be matched to the full appliance tag.
