Some of LG's TROMM washing machines have nine washing modes, including steam washing. Steam is used in the wash cycle for washing performance and to reduce water consumption. You may need to modify some of your laundry day habits because these energy-saving machines require different soap to a normal machine. Problems can arise with these machines if you use regular soap.
M/F Unload the washer promptly if you continue to see wrinkles. Other causes can be the washer being overloaded---don't pack the tub---or the hot and cold water inlets being reversed. Pull the machine away from the wall and make sure the labels match the wall outlets.
M/F Reduce the detergent amount if you see excessive sudsing. Check that you are using High Efficiency detergent. It will be marked with the "HE" logo.
M/F Stop the washer and check the drum and drain filter for foreign objects if you hear rattling or clanking noises. Some thumping is normal; it's caused by heavy loads. If it persists, the washer is out of balance and you should stop and redistribute the load.
M/F Confirm that you are using High Efficiency (HE) laundry detergent in the correct amounts if you get a musty or mildew-like smell in the tub. Check the HE detergent instructions to verify quantities. Run the "Tub Clean" cycle periodically.
M/F Check all the hoses if you see leaking. The fill hose connections at the back should be tight. Unclog the drain pipe if necessary.
M/F These models also have a further steam function that kicks in at the end of the wash to get rid of wrinkles. You can use this "SteamFresh" cycle on its own to give your clothes a blast of steam and refresh them.
