LG Washer Dryer: not operating
What is this symptom?
If your LG washer dryer combo is not operating, it may show no signs of power, with no lights or response to controls. This issue can stem from various causes, including power supply problems or internal component failures. Understanding these common issues can help you troubleshoot effectively.
Important Tips for LG Models
- LG washer dryer combos use water‑free condense drying systems with specific drain hose configuration; unrelated to power issues but important for other symptoms like drying problems. (
