Does it have sterilizing function?

Hello, Renata! Thank you for sharing your question to us about the LG Washer (WM3400CV). No, this model does not include a dedicated sterilizing cycle such as Sanitary or Steam functions found on higher‑end units. Instead, it offers core wash cycles like Normal, Heavy Duty, Speed Wash, Delicates, and Tub Clean. The Tub Clean cycle is especially useful for maintaining hygiene inside the washer by running a high‑temperature cleaning cycle with liquid bleach or specialized washer cleaner.
