Q: Questionhow do I clean the filter behind the panel door
Asked by Rock.
- A:Answer Hi there, Rock. Thank you for sharing your inquiry with us. We understand your question about cleaning the drain pump filter on your LG Front Load Washer, Model WM4000HWA. Regular cleaning helps maintain the performance of your unit. Here are the basic steps for cleaning the drain pump filter: Ensure the washer is off and grab a shallow pan and a towel. Open the access panel door, which is located on the lower front corner of the unit. Carefully pull out the small residual drain hose, place the hose into your pan, and remove its plug to drain the remaining water. Once drained, put the plug back in the hose and reinsert it. Remove the main pump filter by turning the large cap counter-clockwise. Clean any debris or lost items from the filter and its housing. Reinstall the clean filter by turning it clockwise until it is securely locked, and close the access panel.

Q: QuestionWhy do I need to use a 4 prong cord vs a 3 prong?
Asked by Jul.
- A:Answer Hi, Jul. Thanks for your question about the LG Washer (WM4000HWA) model and the difference between 3- and 4-prong cords. The 4-prong cord is beneficial as it has separate grounding and neutral wires, reducing electrical shock risks and ensuring proper grounding, which is crucial for modern washers and dryers. In contrast, 3-prong cords, common in older homes (built before 1996), have two "hot" wires and a combined neutral/ground wire. Choosing between a 3-prong or 4-prong cord depends on your home’s electrical outlet, not the dryer. This unit is compatible with both, but cords aren't included due to varying home wiring, so select the right one for your outlet.

When ready, press Start/Pause again to resume the wash. https://www.bestbuy.com/site/lg-4-5-cu-ft-high-efficiency-stackable-smart-front-load-washer-with-steam-and-built-in-intelligence-white/6419621.p?skuId=6419621 If you need further assistance or have any other questions, please send us a private message on social media @LGUSSupport.
