Washer filling: supply clues and handoff LG WM4000HWA Distinguish the household water observations from the washer display. Keep leak evidence separate so the machine is not run again to recreate it. 1. Check an IE inlet error from outside Status: Planned Reason: Start with accessible valves, visible hoses and household flow for an IE or filling symptom. Continue / skip: Begin only for IE or failure to fill, from a safe dry position. Skip this step if the issue is solely a previous leak. Stop: Stop for an active leak, damaged wiring, a stuck valve or any check that requires moving the washer or undoing plumbing. Guide: https://csl-13-appliance-repair.pages.dev/tasks/lg-ie-inlet/ 2. Record external clues after a water leak Status: Planned Reason: Record where water was previously seen for a technician or plumber, without a new test cycle. Continue / skip: Continue only when a leak actually occurred and observations can be made safely from a dry location. Skip if there has been no leak. Stop: Stop if leakage is active or observing would involve standing water, wet power or moving the appliance; keep the washer out of use. Guide: https://csl-13-appliance-repair.pages.dev/tasks/lg-leak-check/ YOUR PLANNING RECORD A filling and service handoff: actual display, accessible supply findings, household flow, any previous leak location and the appropriate appliance-support or plumbing next step. Notes: ____________________ A plan status records an observation or decision. It does not complete the linked task or certify a repair. FULL TASK GUIDES Check an IE inlet error from outside LG WM4000HWA Region: US | Content version: 2.0.0 Check supply valves, visible hoses and household flow without disconnecting plumbing. 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 [ ] Dry hands and floor; stop if there is leakage or damaged wiring. [ ] Inspect only reachable hoses without moving the washer or disconnecting a fitting. TOOLS - No tools needed MATERIALS - No materials needed FULL CHECKLIST 1. Check that the accessible hot and cold supply faucets are fully open. Do not force a stuck valve. Source: LG WM4000H*A / WM4080H*A Owner’s Manual; pp. 43 2. Look along visible inlet hoses for kinks, pinching or crushing. Do not pull the machine or alter a connection to reach them. Source: LG WM4000H*A / WM4080H*A Owner’s Manual; pp. 43 3. Check water flow at another household faucet. Low household flow points to a plumbing issue; contact a plumber. Source: LG WM4000H*A / WM4080H*A Owner’s Manual; pp. 43 4. If household flow and external conditions are normal but IE remains, arrange support. Inlet-screen cleaning requires a separate water-isolation procedure, which this checklist does not perform. Source: LG WM4000H*A / WM4080H*A Owner’s Manual; pp. 43 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 IE displayed or is filling absent? Is IE displayed or is filling absent? Is IE displayed or is filling absent? A fill message is an observation, not a valve diagnosis. Inspect from a dry position with the washer assembled. - Filling is normal and IE is absent -> Choose the next inlet check. Normal filling needs no action here. If filling remains poor after the external checks, inlet screens are one possible user-maintenance check under a separate isolation procedure. A persistent IE message does not establish that a valve has failed. - IE appears or filling is absent -> Continue to: Are both accessible water faucets fully open?. - I have not checked this yet -> 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 both accessible water faucets fully open? Are both accessible water faucets fully open? Open only an intact, freely moving faucet. Leave stuck valves and inaccessible connections for a plumber or installer. Follow checklist steps: 1 - Both are open, or an ordinary closed faucet was opened -> Continue to: Do the visible inlet hoses have a clear route?. - A valve is stuck, leaking or inaccessible -> 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. - I cannot confirm the faucet positions -> 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 the visible inlet hoses have a clear route? Do the visible inlet hoses have a clear route? Check without moving the washer or disconnecting a hose. Note kinking, crushing and any leak-limiting hose label. Follow checklist steps: 2 - No visible kink or crushing -> Continue to: Is water flow at another household faucet normal?. - Hose is kinked, crushed or damaged -> 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 route is not visible -> 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 water flow at another household faucet normal? Is water flow at another household faucet normal? Use a normal household faucet only. Low household flow calls for a plumbing assessment. Follow checklist steps: 3 - Household flow appears normal -> Continue to: Does the next normal fill complete?. - Household flow is unusually weak or absent -> 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. - I have not checked another faucet -> 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. Does the next normal fill complete? Does the next normal fill complete? If IE remains with normal external conditions, choose the separate inlet-screen task only when both supplies and power can be isolated safely. Otherwise request service. Follow checklist steps: 4 - Filling resumes without IE -> Result recorded. You recorded the task result from your own observation. Keep the before and after notes and recheck during normal use. This record does not certify the appliance condition. - IE or poor filling remains -> Choose the next inlet check. Normal filling needs no action here. If filling remains poor after the external checks, inlet screens are one possible user-maintenance check under a separate isolation procedure. A persistent IE message does not establish that a valve has failed. - No new fill has 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. RESULT OBSERVATIONS - An external restriction is identified, or filling resumes after opening the supply YOUR RECORD Observation date: ____________________ BEFORE IE and external supply conditions: ____________________ AFTER Household flow and next-fill result: ____________________ Additional observations: ____________________ Result / reason for stopping: ____________________ Next action: ____________________ REMINDER Use when IE appears or filling changes; no scheduled diagnostic interval.
