Q: QuestionWhat is the warranty
Asked by Chicken.
- A:Answer Do not count on the warranty being very helpful. LG support is terrible, and you will be without a washer so long waiting for repairs that you will be forced to buy a new one.

Q: QuestionHas anyone had issues with this machine rinsing? Just got it and on it doesn't do a rinse, it just sprays clothes while spinning.
Asked by Mike.
- A:Answer The rinse cycle on the ENERGY STAR® Certified LG 5.5 cu. Ft. Mega Capacity Smart Top Load Washer with Impeller, EasyUnload™ & AI Sensing, Model # WT8400CW, does not work like on older top load washers. It is designed to remove detergent residue, excess water, and other impurities from your clothes. It uses fresh water to flush away any lingering residue that might irritate your skin or leave your clothes stiff. The rinse cycle is often combined with a spin cycle, which removes excess water from your clothes by spinning them rapidly in a drum. This helps to speed up the drying process and prevent your clothes from being overly damp...^Ivan.

Q: QuestionIs there a soaking option ?
Asked by ML.
- A:Answer There is NOT a soaking option. I’ve had to try different things with pausing the machine to be able to soak. Regardless of what the LG customer service person said, there is NO SOAK OPTION on this model. If I had known that, I probably wouldn’t have bought it. And you cannot download a soak optio.

Q: QuestionDoes the 8400 series have the same Deep Fill Max option as the older 7400 series? On those, you could hold the Deep Fill button for 3 secs to activate the Deep Fill Max water option. Don't see that on these newer models. Is it available in the app?

Q: QuestionWhat is the total height with the lid in open position?
Asked by Saul.
- A:Answer Hi there, Saul. Thank you for reaching out with your question. We understand you're asking about the total height of the LG WT8400CB Top Load Washer with the lid in the open position. While the product height is listed as 43 inches with the lid closed, the total height with the lid open will be approximately 59 inches. This accounts for the additional height when the lid is fully raised. https://www.lg.com/us/washers-dryers/lg-wt8400cb-top-load-washer#pdp_specs If you have any more questions or need further assistance, feel free to send us a private message on social media @LGUSSupport, and our team will be happy to help.

Q: QuestionThis machine mess up clothes as pilling the fabric. How to "make" a gentle and delicate cycle?
Asked by Eswn.
- A:Answer Pilling of garments in the LG 5.5 cu. Ft. Mega Capacity Smart Top Load Washer with Impeller, EasyUnload™ & AI Sensing, Model # WT8400CW, or any other washing machine regardless of brand or manufacturer, is due to excessive agitation, high spin speeds, or overloading. When clothes rub against each other too much, it leads to fiber breakage and tangling, creating those annoying pills. Using gentle cycles, lower spin speeds, and washing similar fabrics together can help reduce this problem. Excessive agitation during wash cycles can cause fibers to break and tangle, leading to pilling on clothes. High spin speeds may create friction between garments, increasing the likelihood of fabric pilling. Overloading the washing machine restricts movement, resulting in more rubbing and wear on fabrics. Using hot water can weaken fibers, making them more prone to pilling compared to cold or warm washes. Washing different fabric types together can heighten friction, contributing to pilling on softer materials. Some fabrics attract and bind lint to them, while others give off lint in the laundry process. Avoid mixing these lint collectors and lint producers in the same load. Mixing these fabrics will result in pilling and linting on the lint collectors. (For example, lint collector - knit sweater; lint producer - terry cloth towels.). Many articles of clothing include a fabric care label. You should adjust the cycle and option selections to care for your clothing according to the manufacturer’s recommendations. To avoid overloading the washer, the washer can be fully loaded, but the tub should not be tightly packed with items. The lid of the washer should close easily. Although the washer does not have a 'Delicates' cycle, it has a Downloaded cycle with which you can use your smartphone to download a specialized cycle to this cycle position, the default cycle is the Delicates cycle. You can refer to the LG ThinQ application to see other cycles that are available for download....^Ivan.

Q: QuestionWhy its too loud first used after delivery?
Asked by JoshuaC.
- A:Answer Is the ENERGY STAR® Certified LG 5.5 Cu. Ft. High Efficiency Smart Top Load Washer with EasyUnload - Alpine White, Model # WT8400CW, too loud during the wash cycle, the spin cycle or throughout the entire wash cycle? The tub of the washer spins at very high speeds so if it is not installed on a level, solidly constructed floor capable of supporting the washer without flexing or bouncing, if the leveling feet are adjusted more than necessary, or failure to remove shipping materials can cause excessive noise and vibration. You also need to make sure that the floor is clean, dry and free of dust, dirt, water and oil so the leveling feet cannot slide easily. Leveling feet that can move or slide on the floor can contribute to excess vibration and noise...^Ivan.
