Review inlet hose condition and age LG WM4000HWA Region: US | Content version: 2.0.0 Record visible wear and installation age, then decide whether to retain, investigate or replace the inlet hoses. MODEL AND MANUAL Exact model: WM4000HWA Rinse+Spin button with Control Lock marking; Tub Clean cycle. Compare your supplied manual with MFL71728908 Rev.02_051022. Manual: MFL71728908 Rev.02_051022 Excludes: WM3400CW; WM4000HBA; WM4080HWA; WM4000HWA with a different control panel or manual instructions PREPARATION [ ] Stop use for any active leak. Isolate power and water only from a safe, dry position. [ ] Inspect only visible, accessible inlet hoses. Keep fittings attached; do not pull out or tilt the washer to finish this record. TOOLS - Flashlight, optional MATERIALS - Installation or replacement record, if available FULL CHECKLIST 1. Record when the hot and cold inlet hoses were installed or last replaced. Use an installation receipt or service record; mark the age unknown if none is available. Source: LG WM4000H*A / WM4080H*A Owner’s Manual; pp. 4–6, 12–13 2. With the washer off, visually inspect the reachable hose lengths and couplings for cracks, leakage and wear. Do not bend or loosen a hose to inspect it. Source: LG WM4000H*A / WM4080H*A Owner’s Manual; pp. 4–6, 12–13 3. Look for pinching, crushing or tight bends where the visible hoses approach the washer. Arrange an installer for inaccessible routing rather than moving the machine. Source: LG WM4000H*A / WM4080H*A Owner’s Manual; pp. 4–6, 12–13 4. The manual specifies replacement every five years, with earlier replacement when wear or leakage is present. Record a replacement action for hoses at that age or older; unknown age requires checking records or asking an installer. Source: LG WM4000H*A / WM4080H*A Owner’s Manual; pp. 4–6, 12–13 5. Give the installer the observed condition and age evidence. Have suitable new hoses and the connections checked according to the installation manual; do not reuse old hoses for a new installation. Source: LG WM4000H*A / WM4080H*A Owner’s Manual; pp. 4–6, 12–13 STOP CONDITIONS - Smoke, a burning smell, damaged wiring, standing water near power, or an active leak: stop using the appliance. Disconnect power only from a safe, dry location and arrange qualified service. - Stop if a part is damaged, jammed, sharp, inaccessible, or does not match your manual. Do not force parts or remove a cabinet panel. BRANCH CHECKS Begin with: Is there reliable evidence of the inlet hose age? Is there reliable evidence of the inlet hose age? Is there reliable evidence of the inlet hose age? Use an installation or replacement record, not the washer purchase date unless it also establishes when these hoses were fitted. Follow checklist steps: 1 - Installation or replacement date is documented -> Continue to: Do accessible hose surfaces and couplings look intact and dry?. - No reliable age evidence is available -> Establish hose age. Check installation records or ask the installer. Unknown age does not prove a failed hose, but it cannot establish that the five-year replacement point is still in the future. - I have not looked for the record -> Observation still needed. Your notes are saved. The missing observation is not evidence of a fault or a completed action. Complete only the steps you can perform safely, or ask for help. Do accessible hose surfaces and couplings look intact and dry? Do accessible hose surfaces and couplings look intact and dry? Observe the reachable portions with the washer off. Do not undo a fitting, bend a hose or move the appliance. Follow checklist steps: 2 - Visible surfaces are dry with no wear or cracks -> Continue to: Are the visible hoses free of crushing, pinching and tight kinks?. - Cracks, wear or leakage are visible -> Continue to: Is the replacement or routing assessment ready for an installer?. - The surfaces cannot be seen safely -> Observation still needed. Your notes are saved. The missing observation is not evidence of a fault or a completed action. Complete only the steps you can perform safely, or ask for help. Are the visible hoses free of crushing, pinching and tight kinks? Are the visible hoses free of crushing, pinching and tight kinks? Leave inaccessible routing to an installer. A visible problem is grounds for assessment, not a reason to pull the machine out. Follow checklist steps: 3 - Visible route is clear -> Continue to: Are the documented hoses younger than five years?. - A kink, pinch or crushed area is visible -> Continue to: Is the replacement or routing assessment ready for an installer?. - The route has not been observed -> Observation still needed. Your notes are saved. The missing observation is not evidence of a fault or a completed action. Complete only the steps you can perform safely, or ask for help. Are the documented hoses younger than five years? Are the documented hoses younger than five years? The manual says to replace inlet hoses every five years and check periodically for wear and leaks. Visual appearance does not extend that replacement interval. Follow checklist steps: 4 - Under five years and no visible concern was found -> Visible hose review recorded. The documented hose age is under five years and the reachable portions showed no concern. Keep periodic checks and plan replacement from the actual installation date; hidden sections were not inspected. - Five years old or older -> Continue to: Is the replacement or routing assessment ready for an installer?. - I have not compared the documented dates -> Observation still needed. Your notes are saved. The missing observation is not evidence of a fault or a completed action. Complete only the steps you can perform safely, or ask for help. Is the replacement or routing assessment ready for an installer? Is the replacement or routing assessment ready for an installer? Record age and visible condition. Keep the washer out of use for leakage or damaged hoses; isolate water and power only from a dry safe position. Follow checklist steps: 5 - Observed concern is recorded for qualified help -> Pause and arrange qualified help. Keep the appliance out of use if a safety concern remains. Give the technician the exact model, the visible symptom and any displayed code. Do not open the cabinet or make electrical measurements. - Water is active or isolation is unsafe -> Pause and arrange qualified help. Keep the appliance out of use if a safety concern remains. Give the technician the exact model, the visible symptom and any displayed code. Do not open the cabinet or make electrical measurements. - The handoff note is not prepared -> Observation still needed. Your notes are saved. The missing observation is not evidence of a fault or a completed action. Complete only the steps you can perform safely, or ask for help. RESULT OBSERVATIONS - The accessible condition and age evidence are recorded with a clear retain, investigate or replacement action. YOUR RECORD Observation date: ____________________ BEFORE Documented hose installation or replacement date: ____________________ AFTER Visible condition and action: ____________________ Additional observations: ____________________ Result / reason for stopping: ____________________ Next action: ____________________ REMINDER Inspect periodically; replace inlet hoses every five years. Use the documented installation date, not this inspection date, to plan replacement. Interval: Choose a personal interval; basis: user-selected Source: lg-manual; p. 12 A calendar reminder is a personal plan, not a record of work completed.
