User manual Washer for LG Electronics WT7100CW
Choosing the Proper
Location Install the washer on a solid floor that is strong and rigid enough to support the weight of the washer, even when fully loaded, without flexing or bouncing. If the floor has too much flex, you may need to reinforce it to make it more rigid. If the floor is not solid, it may cause severe vibration and noise.
NOTE
Power Outlet
Flooring
Floor Installation

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

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




NOTE
Connecting the Drain Hose
Connect the drain hose to either a standpipe or laundry tub.
NOTE
Option 1: Standpipe


Option 2: Laundry Tub
Position the washer in its final location. Take special care not to pinch, strain, or crush the water and drain lines. If you have a carpenter’s level, you can use it to check that the washer level. The slope beneath the washer should not exceed 1 inch, and all four leveling feet must rest firmly on the floor.
Open the lid (door) and look from above to see if the tub is centered. If the tub is NOT centered, readjust the front feet. If you have a level, check the washer with the level.
Adjust the lower leveling feet. Turn in one direction to raise the washer or the other direction to lower it.
Recheck the washer’s levelness. Push or rock the top edges of the washer gently to make sure the washer does not rock. If the washer rocks, repeat steps 1-3.
Leveling the Washer
The tub of the washer spins at very high speeds. To minimize vibration, noise, and unwanted movement, the floor must be a level, solid surface.



Cycle Modifier Buttons
Each cycle has default settings that are selected automatically. You may also customize these settings using the cycle modifier buttons. Press the button for the desired modifier until the indicator light for the desired setting is lit. The washer automatically adjusts the water level for the type and size of wash load for best results and maximum efficiency. Due to the high-efficiency nature of this product, water levels may be much lower than expected. This is normal and cleaning/rinsing performance will not be compromised.
NOTE

Temp.
Temp. selects the wash and rinse temperature combination for the selected cycle.
NOTE
Spin
Higher spin speeds extract more water from clothes, reducing drying time and saving energy.
Soil
Adjusting the soil level setting will modify the cycle times and/or wash actions.
NOTE
Spin Only
Use this option to drain the water from the tub and spin the clothes. This can be used, for example, if the wash cycle is interrupted by a power failure. The spin speed can be adjusted using the Spin button.
Cold Wash
This option saves energy by using cooler water while increasing the wash and rinse times to maintain wash performance.
NOTE
Signal
The washer plays a melody when the wash cycle is finished. The buttons make a sound each time a button is pressed. Use this option to adjust the volume of the melody and button tones.
Delay Wash
NOTE
Rinse+Spin
Select this option to rinse and spin a load separately from a regular cycle. This can be helpful in preventing fresh stains from setting in fabrics.
Water Plus
Use this option to add extra water to the wash cycle for better wash performance (stain treatment) with large or bulky items.
NOTE
Soak
This option provides a 30-minute presoak prior to the start of the selected cycle. Use the Soak option to presoak garments to help remove difficult spots or stains on fabrics. At the end of the presoak time, the selected cycle will begin with the same water used for soaking.
Extra Rinse
This option will add an extra rinse to the selected cycle. Use this option to help ensure the removal of detergent or bleach residue from fabrics. Liquid fabric softener, if used, is always dispensed in the final rinse.
NOTE
Control Lock
Use this option to disable the controls. This feature can prevent children from changing cycles or operating the machine. The feature does not lock the lid (door). Once the Control Lock is set, it must be deactivated before any controls, except the Power button, can be used. Once the washer has shut off, the Power button will allow the machine to be turned on, but the controls will still be locked. When the controls are locked,
will display alternately with the estimated time remaining.
NOTE
Add Garment
Use this function to add garments or remove foreign objects like coins or keys after the cycle has started.
MAINTENANCE
Care After Wash
After the cycle is finished, wipe the lid (door) and the inside of the lid (door) seal to remove any moisture.
Cleaning the Exterior
Proper care of your washer can extend its life.
Lid (Door):
Wash with a damp cloth on the outside and inside and then dry with a soft cloth.
Exterior:
Care and Cleaning of the Interior
Cleaning the Tub
Over time, residue may build up in the tub, leading to mildew or a musty odor. Run the Tub Clean cycle monthly to remove residue and prevent odor. Run the cycle more often under heavy use conditions or if odor is already present.

For other tub cleaning products, follow the cleaner manufacturer’s instructions and recommendations.
Do not exceed the maximum fill line when adding bleach or powdered cleaners. Powdered cleaners may remain in the tub after cleaning.
NOTE
Removing Mineral Buildup
In areas with hard water, mineral scale can form on internal components of the washer. Periodically clean the mineral buildup on the internal components to extend the lifespan of the washer. Use of a water softener is recommended in areas with hard water.
Leaving the Lid (Door) Open
Cleaning the Dispenser Drawer
Detergent and fabric softener may build up in the dispenser drawer. Remove the drawer and inserts and check for buildup once or twice a month.


NOTE
Cleaning the Water Inlet Filters
If the washer does not fill properly, an error message will show on the display. The inlet valve filter screens could be plugged by hard water scale, sediment in the water supply, or other debris.
Storing the Washer
If the washer will not be used for an extended period of time and is in an area that could be exposed to freezing temperatures, perform the following steps to protect the washer from damage.
Make sure the tub is empty before following these steps.

Rattling and clanking noise
Stop washer, check tub and drain filter for foreign objects. If noise continues after washer is restarted, call for service.
Thumping sound
This is normal. If sound continues, washer is probably out of balance. Stop and redistribute wash load.
Pause the cycle and redistribute the load after the lid (door) unlocks.
Vibrating noise
See Unpacking and Removing Shipping Material in the Installation section.
Pause the cycle and redistribute the load after the lid (door) unlocks.
See Leveling the Appliance in the Installation section.
Make sure that the floor is solid and does not flex. See Flooring in the Installation section.
Squeaking noise
See Unpacking and Removing Shipping Material in the Installation section.
Banging noise when washer is filling with water (Water Hammer)
Water hammer is not caused by a defect in the washer. Install water hammer arrestors (purchased separately at hardware or home improvement store) between the fill hose and the washer for best results.
Adjust household water supply regulator to a lower pressure or contact a plumber.
Water leaking
Check hoses and connectors for leaks, cracks and splits.
Check and tighten hose connections.
The washer pumps out water very rapidly. Check for water backing up out of the drain pipe during drain. If water is seen coming out of the drain, check for proper drain hose installation and check for restrictions in the drain. Contact a plumber to repair drain pipe.
Tie drain hose to inlet hose or standpipe to prevent it from coming out during drain. For smaller drain pipes, insert the drain hose into the pipe as far as the drain hose flange. For larger drain pipes, insert the drain hose into the pipe 1-2 inches past the flange.
Use the Bedding cycle for large or bulky items. Use extra care and never wash more that half a load of items that float, such as pillows.
Stop the washer and check the load. Make sure the load does not crest above the top edge of the tub.
Oversudsing may create leaks, and may be caused by the type and amount of detergent used. High-Efficiency detergent is the only detergent recommended. The normal amount of detergent to use is 1/4 to 1/2 of the maximum amount recommended by the detergent manufacturer. Always reduce the amount of detergent if the load is small or lightly soiled, or if the water is very soft. Never use more than the maximum amount recommended by the detergent manufacturer.
Water leaks every load.
Check all fill and drain hose connections to ensure that they are tight and secure.
Excessive sudsing
HE detergents are formulated specifically for High-Efficiency washers and contain sudsreducing agents. Only use detergent with the High-Efficiency (HE) logo.
For detergent quantities refer to the Detergent Use section. If sudsing or detergent residue continue to be an issue, add an extra rinse.
Washer will not turn on.
Make sure that the plug is plugged securely into a grounded, 3-prong, 120-VAC, 60 Hz outlet.
Reset circuit breaker or replace fuse. Do not increase fuse capacity. If the problem is a circuit overload, have it corrected by a qualified electrician.
Wash cycle time is longer than usual.
This is normal. The washer adjusts cycle time automatically to provide optimal results for the selected cycle. The time remaining shown in the display is only an estimate. Actual time may vary.
Incomplete or no dispensing of detergent
Make sure that detergent and additives are put into the correct dispenser compartments. For all detergent types, always make sure that the dispenser drawer is fully closed before the start of the cycle.
Make sure that the suggested amount of detergent is used per the manufacturer’s recommendations. You may also dilute the detergent with water to the maximum fill line on the compartment to avoid clogging. Use only HE (High-Efficiency) detergent. NOTE: Always use as little detergent as possible. High-Efficiency washers need very little detergent to achieve optimum results. Using too much detergent will cause poor wash and rinse performance and may contribute to odors in washer.
Make sure that both hot and cold water faucets are turned on all the way
It is normal for a small amount of detergent to remain in the dispenser. If this residue builds up it can interfere with normal dispensing of products. Refer to the cleaning instructions.
Washer will not operate.
This is normal. Press the Power button to turn the washer on.
Make sure cord is plugged securely into a working outlet.
Turn both hot and cold faucets fully on.
Make sure the cycle was set correctly, close the lid (door) and press the Start/Pause button.
The washer will not operate if the lid (door) is open. Close the lid (door) and make sure that nothing is caught under the lid (door) preventing it from closing completely.
Check house circuit breakers/fuses. Replace fuses or reset breaker. The washer should be on a dedicated branch circuit. The washer will resume the cycle where it stopped once power is restored.
Press the Power button, then re-select the desired cycle and press the Start/Pause button.
Press the Power button then re-select the desired cycle and press the Start/Pause button. The washer will shut off if the Start/Pause button is not pressed within 60 minutes.
Check another faucet in the house to make sure that household water pressure is adequate.
If the washer has been exposed to temperatures below freezing for an extended period of time, allow it to warm up before pressing the Power button. Otherwise, the display will not come on.
Washer is not filling properly.
Make sure the inlet filters on the fill valves are not clogged. Refer to the filter cleaning instructions.
Check that inlet hoses are not kinked or clogged.
This is a High-Efficiency (HE) washer. As a result, the water level settings for this washer may be different than for conventional washers.
Make sure that both hot and cold water faucets are turned on all the way
The washer will not operate if the lid (door) is open. Close the lid (door) and make sure that nothing is caught under the lid (door) preventing it from closing completely.
The water will not normally cover the clothes. The fill level is optimized for the wash motion to achieve the best wash performance.
Water in the washer does not drain or drains slowly
Make sure the drain hose is free of clogs, kinks, etc., and is not pinched behind or under the washer.
Move the end of the drain hose so it’s lower than 96 inches (2.4 m) above the bottom of the washer.
Bleach does not dispense
Make sure that the bleach cover is properly installed and snapped into place before the beginning of the cycle.
Lift out the bleach dispenser cover and clean out the reservoir. Lint and other foreign debris that collects in the inside the dispenser may prevent proper dispensing of the bleach.
Premature dispensing of bleach
You cannot store bleach in the dispenser for future use. The bleach will be dispensed every load.
Overfilling the bleach dispenser will cause the bleach to dispense immediately, which will damage the laundry or the washer. Always measure bleach, but never fill above the max line on the dispenser. A half cup of bleach is sufficient for most loads. Never use more than 1 cup of bleach.
Wrinkling
Always remove items from the washer as soon as the cycle is complete.
The washer can be fully loaded, but the tub should not be tightly packed with items. The lid (door) of the washer should close easily.
Hot water rinse can set wrinkles in garments. Check the inlet hose connections.
Staining
Dispenser compartment is overfilled causing bleach or softener to dispense immediately. Always measure bleach to prevent overfilling one cup maximum.
Dispenser drawer closed too quickly causing softener to dispense immediately.
Always use the dispensers to ensure that laundry produdcts are properly dispensed at the right time in the cycle.
Always remove items from the washer as soon as possible after the cycle is complete.
Always wash dark colors separately from light colors and whites to prevent discoloration.
Never wash heavily soiled items with lightly soiled items.
Poor stain removal
Heavier soils and tougher stains may require extra cleaning power. Select the Soak or Stain Care feature to boost the cleaning power of the selected cycle.
Articles that have previously been washed may have stains that have been set. These stains may be difficult to remove and may require hand washing or pre-treating to aid in stain removal.
Musty or mildewy odor in washer
Use only High-Efficiency (HE) detergent in accordance with the manufacturer’s instructions.
