    Why are my clothes wrinkled after washing in my LG WM3488H Washer?
    • B
      Brandon McdanielSep 12, 2025
      If you find your clothes are wrinkling after being washed in your LG Washer, remove the load immediately after it finishes. Avoid overloading the tub. Check the inlet hose connections to ensure hot and cold water inlets are not reversed, as hot water rinse can cause garments to wrinkle.

      If your LG Washer has water leaking around it, check the faucets and water lines for leaks. Also, inspect the drain pipe or drain hose for clogs and unclog them if necessary. If you can't unclog it yourself, contact a plumber.

    Why won't my LG WM3488H turn on?
    • B

      If your LG Washer won't turn on, make sure the power cord is properly plugged into a grounded 3-prong, 120 V (60 Hz) outlet. Also, check if a house fuse has blown, a circuit breaker has tripped, or a power outage has occurred. Reset the circuit breaker or replace the fuse, without increasing its capacity. If the problem is a circuit overload, consult a qualified electrician.

      If clothing gathers on one side of the tub in your LG Washer, rearrange the items to help balance the load. If you are washing stuffed animals or mats, rearrange the knitwear to help balance the load and drain it again. When washing blankets, put one blanket in at a time.

      Steven GrahamSep 18, 2025
      If you hear a banging noise when your LG Washer is filling with water (Water Hammer) and plumbing in the home moves or flexes when the water valves in the washer shut off, install water hammer arrestors (purchased separately at hardware or home improvement store) between the fill hose and the washer. If the household water supply pressure is very high, adjust household water supply regulator to a lower pressure or contact a plumber to have a regulator installed.

    Why is water not supplied to my LG WM3488H Washer or the water pressure is low?
    • A
      Ashley YoungSep 7, 2025
      If water is not being supplied to your LG Washer, or the water pressure is low: turn on the faucets; if a faucet is frozen, thaw it with warm water; check that the water lines are not pinched or bent, taking extra care that water lines are not twisted or pinched by other objects.

    Why does my LG Washer smell bad?
    • P
      Pedro HinesSep 23, 2025
      During the initial phase of operation of your LG Washer, lint from laundry can settle on the heater and cause strange odors. This is normal and will not affect performance. If it is the first time using washer, smell comes from the rubber attached to the washer door and it will eventually dissipate after first couple of wash cycles. Periodically clean the gasket. Mold and foreign substances inside the gasket may produce mildew or musty smells. Clean the drain pump filter regularly, as foreign substances on it may produce mildew or musty smells. If the drain hose is not installed properly, the odor may be emitted because of a backflow of drainage into the tub. Make sure that the drain hose is not kinked or clogged.

    What to do if my LG WM3488H Washer is draining slowly?
    • M
      Mrs. Melinda HancockAug 31, 2025
      If your LG Washer is draining slowly or not at all, ensure the drain hose is positioned within 3 feet below the end of the elbow bracket. Position the drain hose on a smooth surface to prevent bending. If the drain hoses are frozen, thaw them with warm water. Also, open the drain pump plug cap and remove any accumulated dirt.
