Choosing the Proper Location

Check the following requirements for the install location before installing the washer.

  • Allow for sufficient space between the walls and the washer for installation.
  • Make sure that the floor is clean, dry and free of dust, dirt, water and oil so the leveling feet cannot slide easily. Leveling feet that can move or slide on the floor can contribute to excess vibration and noise.
  • If the floor has too much flex, reinforce it to make it more rigid. If the floor is not solid, it may cause severe vibration and noise.
  • If a drain pan must be used, take extra care to follow the instructions provided with the drain pan and make sure the leveling feet are adjusted for firm and even contact with the pan. Use of drain pans and failure to properly level the washer may result in increased vibration and noise during operation.

Power Outlet

  • The power outlet must be within 60 inches (1.5 m) of either side of the washer.
  • Position the washer so that the outlet and plug are easily accessible.
  • Do not overload the outlet with more than one appliance.
  • The outlet must be grounded in accordance with current electrical wiring codes and regulations.
  • Use a time-delay fuse or circuit breaker.
  • It is the personal responsibility and obligation of the washer owner to have a proper outlet installed by a qualified electrician.

Flooring

  • To minimize noise and vibration, install the washer on a level, solidly constructed floor capable of supporting the washer without flexing or bouncing.
  • The washer must be installed on firm flooring to minimize vibration during the spin cycle. Concrete flooring is best, but a wood floor is sufficient, provided it is built to FHA standards.
  • The floor under the washer must not slope more than 1 inch (2.5 cm) from front to back or side to side.
  • Installing on carpeting and soft tile surfaces is not recommended.
  • Never install the washer on a platform or weakly supported structure.

Floor Installation

To ensure sufficient clearance for water inlet hoses, drain hose and airflow, allow minimum clearances of at least 1 inch (2.5 cm) at the sides and 4 inches (10 cm) behind the washer. Be sure to allow for wall, door, or floor moldings that may increase the required clearances.

Connecting the Water Inlet Hoses

To avoid the risk of costly water damage, purchase and install new water inlet hoses when installing the washer.

caution iconWARNING

  • Do not overtighten the hoses or cross-thread the hose fittings. Overtightening or cross-threading can damage the valves or couplings, resulting in leaking and property damage.
  • Do not reuse old hoses. Use only new hoses when installing the washer. Old hoses could leak or burst causing flooding and property damage. Contact an LG Customer Information Center for assistance in buying hoses.

NOTE

  • Periodically check the hoses for cracks, leaks, and wear, and replace the hoses every five years.
  • Do not stretch the water hoses intentionally, and make sure that they are not pinched, crushed or kinked by other objects.
  • Water supply pressure must be between 20 psi and 120 psi (138 – 827 kPa). If the water supply pressure is more than 120 psi, a pressure reducing valve must be installed.
  • Your hot water heater should be set to deliver water at 120–135 °F (48–57 °C) to allow the washer to properly control wash temperatures.
  • Do not store or install the washer in a location subject to freezing temperatures. Damage to the water inlet hoses and internal mechanisms of the washer can result. If the washer was exposed to freezing temperatures prior to installation, allow it to stand at room temperature for several hours before use and check for leaks prior to operation.
  • Do not use flood-preventing hoses with auto shut off devices. The devices can be tripped during fill and prevent the washer from filling properly.

How to Connect the Water Inlet Hoses

1. Check the fittings and seals. Inspect the threaded fitting on each hose and make sure there is a rubber seal a in place in both ends of each hose to prevent leaking.

LG WM4000HWA Ultra Large Capacity Smart wi-fi Enabled Front Load Washer User Manual - How to Connect the Water Inlet

2 Connect the water supply hoses.
• Connect the water inlet hoses to the hot and cold water faucets tightly by hand and then tighten another 2/3 turn with pliers.
• Connect the blue hose to the cold water faucet and the red hose to the hot water faucet.

Connecting the Drain Hose

Connect the drain hose to either a standpipe or laundry tub.

caution iconWARNING

  • The drain hose should always be properly secured. Failure to properly secure the drain hose can result in flooding and property damage.

NOTE

  • The drain must be installed in accordance with any applicable local codes and regulations.
  • Make sure that the drain hose is not stretched, pinched, crushed, or kinked.
  • The end of the drain hose should be located a minimum of 24″ (61 cm) and a maximum of 96″ (244 cm) above the bottom of the washer.
  • For best results, locate the end of the drain hose no higher than 66″ (168 cm) above the bottom of the washer. As the drain outlet is raised beyond 66″ (168 cm), the drain function will be increasingly affected.
  • Never create an airtight seal between the hose and the drain with tape or other means. If no air gap is present, water can be siphoned out of the drum resulting in poor wash/rinse performance or clothing damage.

Using a Standpipe to Drain

1.Clip the end of the hose into the elbow bracket.

    • Press the Start/Pause button to begin the cycle. The door locks, and the washer agitates briefly without water to measure the weight of the load.
    • If the Start/Pause button is not pressed within a certain time, the washer shuts off and all settings are lost.
  7. End of cycle.
    • When the cycle is finished, a melody sounds. Immediately remove the clothing from the washer to reduce wrinkling.
    • Check around the door seal when removing the load for small items that may be caught in the seal.

NOTE

  • The washer rotates the laundry in a way that allows it to use less water while still fully saturating the  clothing. It is normal to be unable to see water during the wash cycle.
  • If the temperature or the water level inside the machine is too high, the door will not unlock when the Start/Pause button is pressed, and the Add Item function will not be available (on applicable models). To stop a cycle and drain the water completely, turn the power off, then on, and then select Rinse+Spin.

Sorting Laundry

Grouping Similar Items

For the best washing results, and to reduce the possibility of damage to clothing, sort clothing into loads made up of similar items.

Mixing different fabric types and/or soil levels can result in poor wash performance, color transfer, discoloration, fabric damage or linting. Fabrics should be sorted into groups as described below.

Colors
Sort articles by color. Wash dark clothes separately from light colors or whites. Mixing dark clothes with light clothes can result in dye transfer or discoloration of the lighter clothes.
Soil Level
Wash heavily soiled clothing together. Washing lightly soiled clothing in the same load with heavily soiled clothing could result in poor wash performance for the lightly soiled clothing.
Fabric Type
Delicate articles should not be mixed with heavy or sturdy fabric types. Washing heavy fabrics with delicates can result in poor wash performance for the heavy fabrics and possible damage to the delicates.
Lint Type
Some fabrics attract and bind lint to them while others give off lint in the laundry process. Avoid mixing these lint collectors and lint producers in the same load. Mixing these fabrics will result in pilling and linting on the lint collectors. (For example, lint collector – knit sweater; lint producer – terry cloth towels.)

caution iconCAUTION

  • Clothing or articles that are waterproof or water-resistant must be washed in the Waterproof, Bedding, Bulky/Large, or Jumbo Wash cycle only. (Examples include water resistant clothing, mattress covers, outdoor clothes, and plastic mats.) Failure to do so may result in personal injury or damage to the washer, clothes, walls, floor, and surrounding objects due to abnormal vibration.
  • Remove the stuffing from pillows and cushions before washing the covers. Failure to do so can cause excessive vibration, resulting in damage to the washer, clothes, nearby objects, walls, and floor.

Fabric Care Labels

Many articles of clothing include a fabric care label. Using the chart below, adjust the cycle and option selections to care for your clothing according to the manufacturer’s recommendations.

Loading the Washer

General Tips

  • Check and empty pockets. Paper clips, coins, matches, and other items can damage clothing and the washer.
  • Close zippers and hooks, and tie drawstrings to prevent snagging or tangling of clothes.
  • Pretreat heavily stained areas for best results.
  • Brush off heavy soil, dust, and hair from items before washing. Excess dirt or sand can abrade other fabrics and lead to poor wash performance.
  • For best performance, load clothes as shown.

    – Do not press down on items while stacking them in the drum.
    – Load clothes loosely, and do not overfill the drum. Clothes need room to circulate in order to get clean.
  • Combine large and small items in the drum. Load large items first. Large items should not be more than half of the total load.
  • The washer can be fully loaded, but the drum should not be tightly packed with items. The door of the washer must close easily.
  • The washer will not fill or operate with the door open.

caution iconCAUTION

  • Clothing or articles that are waterproof or water resistant must be washed in the Waterproof, Bedding, Bulky/Large, or Jumbo Wash cycle only. (Examples include water resistant clothing, mattress covers, outdoor clothes, and plastic mats.) Failure to do so may result in personal injury or damage to the washer, clothes, walls, floor, and surrounding objects due to abnormal vibration.

Bulky Items

  • Wash thick, bulky items individually. Heavy blankets, comforters, bedspreads, or pet beds can get tangled or cause an unbalanced load if combined with other items.

Small Items

  • Do not wash a single small item. Add enough similar items to the load to prevent an out-of balance load.
  • Wash small, light items in a mesh bag. Small items can get caught in the impeller at the bottom of the drum, and brassiere hooks can snag on other clothing or the drum.

Adding Cleaning Products

About Detergent Use

This washer is designed for use with only HE (High Efficiency) detergents.

  • he logoHE detergents produce fewer suds, dissolve more efficiently to improve washing and rinsing performance, and help to keep the interior of the washer clean. Using detergent that is not HE may cause oversudsing and unsatisfactory performance which could result in error codes, cycle failure, and washer damage.
  • Detergents designated as HE-compatible may not provide optimal results.
  • For proper wash performance, always measure detergent using the measuring device provided by the detergent manufacturer. For an average load, use less than half of the recommended maximum. Use less detergent for soft water, light soil, or smaller loads.
  • Use extra care when measuring 2X and 3X concentrated detergents because even a small amount of extra detergent can lead to problems.
  • Never use more than the maximum amount of detergent recommended by the manufacturer. Using too much detergent can lead to oversudsing, poor rinsing, detergent buildup in clothing, and residue buildup that can contribute to odors in the washer.
  • Do not use more than one single-use detergent pack in the washer. Using too much detergent may cause oversudsing and unsatisfactory performance. Reduce detergent amount or add an extra rinse if detergent residue is left on fabrics. To add an extra rinse, select the Extra Rinse option.

Single-Use Detergent Packs / Gel or Tablet Detergents

Place liquid or powdered detergent packs, or gel or tablet detergents in the drum before loading laundry. Do not place these detergents in the dispenser.

Using the Dispenser

To add cleaning products to the automatic dispenser:

  1. Open the dispenser drawer.
  2. Load the laundry products into the appropriate compartments.
    • Follow the manufacturer’s recommendations when adding cleaning products.

    5.Liquid chlorine bleach compartment
  3. Gently close the detergent dispenser drawer  before starting the cycle.
    • Slamming the drawer closed may result in the detergent overflowing into another compartment or dispensing into the drum earlier than programmed.
    • Be careful not to get a hand caught in the drawer while closing.
    • It is normal for a small amount of water to remain in the dispenser compartments at the end of the cycle.

caution iconCAUTION

  • Do not place or store laundry products, such as detergent, bleach, or liquid fabric softener, on top of your washer. These products can damage the washer’s finish and controls.

Pre-wash Detergent Compartment

Add liquid or powdered detergent to this compartment when using the Pre-wash option. Always use HE (High-Efficiency) detergent with your washer.

  • When using the Pre-wash option, liquid detergent for the main wash needs to be loaded in the liquid detergent cup accessory in the main wash dispenser (where applicable), to prevent it from being dispensed with the pre-wash detergent.
  • The amount of detergent added for the Prewash option is 1/2 the amount recommended for the main wash cycle. For example, if the main wash cycle requires one measure of detergent, add 1/2 measure for the Pre-wash option.

Main Wash Detergent Compartment

This compartment holds laundry detergent for the main wash cycle. Either powdered or liquid detergent may be used in this compartment.

  • The detergent is added to the load at the beginning of the cycle. Always use HE (High Efficiency) detergent with your washer.
  • Do not exceed the maximum fill line. Using too much detergent can result in detergent buildup in clothing and the washer.
  • Liquid or powdered color-safe bleach may be added to the main wash compartment with detergent of the same type. Do not mix liquids and powders
  • If the dispenser has a liquid detergent cup and insert:
    – Make sure they are in place when using liquid detergent.
    – Make sure to remove them when using powdered detergent. Powdered detergent will not dispense with the liquid detergent cup and insert in place.
  • If you use a detergent that does not dissolve easily or a detergent with high viscosity, it will leave a residue and clog the dispenser.
