WM4000HWA PE error

Your LG WM4000HWA is showing PE. Before replacing parts, confirm the model tag matches WM4000HWA: Open the door and check the rim or door frame; the silver sticker is also on the rear panel near the top. On this LG washer, PE means Clutch or motor position sensor fault. The steps below follow the field-service order for the WM4000HWA platform — not the generic LG PE page. Cross-check part fit with WM4000HWA before ordering — use the model-specific parts diagram. If the code cleared after a reset but returned mid-cycle, treat that as a confirmed fault rather than a one-time glitch.
