Frequently Asked Questions - WM3700HWA LG
How to properly install the LG WM3700HWA washing machine?
Place the washer on a solid, level floor. Remove the 4 shipping bolts using the provided wrench and install the caps. Connect new water hoses (red for hot, blue for cold) to the faucets, then to the water inlets at the back. Connect the drain hose to a sink or standpipe respecting heights (0.7 m to 2.4 m). Adjust the feet to level the appliance and tighten the lock nuts. Plug into a 120 V grounded outlet and perform a test with the Rinse+Spin cycle.
What detergents to use and how to dose them?
Use only high-efficiency (HE) detergents. Pour liquid or powder detergent into the main compartment. For prewash, use half the dose. Do not exceed the maximum fill line. Detergent pods should be placed directly into the drum before adding clothes. Never use more than the manufacturer's recommended amount to avoid excess suds and poor rinse performance.
How to use the steam cycles?
Select a compatible cycle (e.g. Normal or Heavy Duty), then press the Steam button. Hot steam improves cleaning of tough stains. Do not use steam on wool, silk, or delicate items. Do not touch the door during the cycle as it becomes very hot. Wait for the lock to release before opening.
What to do if the washer does not drain water?
First, check that the drain pump filter is not clogged. Clean it regularly by removing the cover at the bottom of the appliance. Ensure the drain hose is not kinked or blocked. If the problem persists, check the water inlet filters and clean them if necessary. Refer to the manual for detailed procedure.
How to clean the drum and door gasket?
Use the Tub Clean cycle once a month with a special cleaner or a little bleach. Regularly clean the door gasket with a damp cloth to remove lint and moisture residues. Leave the door ajar between washes to prevent mold. Avoid abrasive cleaners.
The washer vibrates a lot or is noisy, what to do?
Make sure the shipping bolts have been removed. Check that the washer is level by adjusting the feet. Use the anti-slip pads if necessary. An unbalanced load can also cause vibrations: distribute items evenly. Avoid washing waterproof or very heavy items alone.
How to add garments during a cycle?
Press the Add Garments button. The door unlocks after checking temperature and water level. Open, add or remove items, then close the door and press Start/Pause to resume. This function is not available if water is too hot (>45 °C) or during the spin phase.
How to save energy with this washer?
Use the Cold Wash option which washes in cold water with extended time for equivalent efficiency. Select the highest spin speed suitable for the fabric to reduce drying time. The Allergiene cycle uses steam to reduce allergens while being water-efficient. Enable Delay Wash to take advantage of off-peak hours.
How to use the Smart Diagnosis function?
Download the LG SmartThinQ app on your smartphone. In case of a problem, open the app, select the appliance, and launch Smart Diagnosis. Place the phone near the control panel when the washer emits a series of beeps. The app will analyze the diagnosis and may transmit data to a technician for quick repair.
What to do if the washer displays an error code?
Common error codes are: dE (door not closed properly), IE (water inlet issue), OE (drain blocked), UE (imbalance). See the Troubleshooting section of the manual for full meaning. In most cases, check connections, clean filters and redistribute the load. If problem persists, contact LG customer service.
