OPERATION

Before Use

WARNING: To reduce the risk of fire, electric shock, or injury to persons, read the SAFETY INSTRUCTIONS before operating this appliance.

Operation Overview

1. Sort laundry and load the washer.

  • Sort laundry by fabric type, soil level, color and load size as needed. Open the door and load items into the washer.
  • If using single-use detergent packs, or gel or tablet detergents, place them in the drum before loading the laundry.

2. Add cleaning products.

  • Add the proper amount of HE (High-Efficiency) detergent to the detergent dispenser.
  • If desired, add bleach or fabric softener to the appropriate areas of the dispenser drawer.
  • Do not place liquid or powdered detergent packs, or gel or tablet detergents in the dispenser.

3. Turn on the washer.

  • Press the Power button to turn on the washer.

4. Select a cycle.

  • Turn the cycle selector knob or press the cycle buttons repeatedly until the desired cycle is selected.
  • The preset wash temperature, spin speed, soil level and option settings for the selected cycle are shown.
  • The Normal cycle must be selected in order to change its default settings.
  • Pressing the Start/Pause button without selecting a cycle immediately starts the Normal cycle with the default settings.

5. Adjust settings.

  • Default settings for the selected cycle can be changed, if desired, using the cycle modifier and option buttons.
  • Not all modifiers and options are available on all cycles. A different chime sounds and the LED does not light up if the selection is not allowed.

6. Begin cycle.

  • 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 locks and cannot be opened.

Sorting Laundry

CAUTION

  • 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.

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.)

How to Sort Laundry

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

CAUTION: 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.

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.

    See other models: 34BP65C-B LK75C DLHC1455P A939KBGS GSLV50DSXM
    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.

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-ofbalance 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 (HighEfficiency) detergents.

  • HE 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.

  1. Maximum fill line
  2. Average load fill line
  3. Liquid detergent
  4. Powdered detergent

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.

    1. Main wash detergent compartment
    2. Liquid fabric softener compartment
    3. Pre-wash detergent 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: 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.

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 (HighEfficiency) 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.
  • When using powdered detergent, remove the insert and liquid detergent cup from the dispenser. 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.

Fabric Softener Compartment

This compartment holds fabric softener, which is automatically dispensed during the final rinse cycle. Either powdered or liquid fabric softener may be used.

  • Do not exceed the maximum fill line. Using too much fabric softener may stain clothes or cause buildup on fabrics or in the washer.
  • Dilute concentrated fabric softeners with warm water.
  • Never pour fabric softener directly onto the load or into the drum.

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.

  • Press the Spin button repeatedly until the desired speed is selected.
  • Some fabrics, such as delicates, require a slower spin speed.

Dry Cycles

General Tips for Drying

Use the automatic cycles to dry most loads. Electronic sensors measure the temperature of the exhaust to increase or decrease drying temperatures for faster reaction time and tighter temperature control.

  • Use the Wash+Dry cycle to automatically wash and dry laundry.
  • For better drying results, make sure all items are similar in material and thickness.
  • Do not overload the appliance by stuffing too many articles into the drum. Items must be able to tumble freely.
  • If you open the door and remove the load before the appliance has finished its cycle, remember to press the Start/Pause button.
  • After the end of dry, ENd is displayed.

Woolen Articles
Do not tumble dry woolen articles. Pull them to their original shape and dry them flat.

TROUBLESHOOTING

Before Calling for Service

The washer is equipped with an automatic error-monitoring system to detect and diagnose problems at an early stage. If the washer does not function properly or does not function at all, check the following before you call for service.

FAQs

Q: Why does my washer make loud banging noises while it is filling with water?

A: This is actually a problem with the plumbing in your home. When the water valve in the washer shuts off, it can cause pipes in your home to move, resulting in a loud banging noise. This effect, called water hammer, can be reduced by installing an item called a water hammer arrestor. Add-on arrestors can be purchased through your local hardware or home improvement store.

Q: Why is there so little water in my washer? How can it clean the clothes?

A: HE (High-Efficiency) washers are designed to properly wash your laundry while using a minimum amount of water and energy. Because the water volume is low, the small amount of detergent used is more concentrated in the water, resulting in excellent cleaning performance.

Q: When I press a button, why does my washer beep and then nothing happens?

A: The Control Lock feature is turned on. To turn it off, turn on the washer, then press and hold the button that has Control Lock on or under it for 3 seconds.

Q: Where should I pour the powdered laundry products when doing my laundry?

A: If you are using powdered laundry detergent, load it in the main detergent dispenser after removing the liquid detergent insert. Powdered laundry agents or powdered color safe bleach should be put directly into the drum. These products can be put in the empty drum before loading or on top of the laundry after loading the washer.

Operation

Problem Possible Cause & Solution
Water Leaking

Hoses are not connected correctly.

  • Check hoses and connectors for leaks, cracks, and splits.
  • Check and tighten hose connections.

House drain pipes are clogged.

  • 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.

Drain hose has come out of the drain connector or is not inserted far enough.

  • 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.

Oversudsing of detergent

  • Oversudsing may create leaks, and may be caused by the type and amount of detergent used. HE (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.
Excessive sudsing

Too much detergent or incorrect detergent

  • HE detergents are formulated specifically for HE (High-Efficiency) washers and contain suds reducing agents. Only use detergent with the HE (High-Efficiency) logo.
  • For detergent quantities refer to Detergent Use in OPERATION. If sudsing or detergent residue continues to be an issue, add an extra rinse.

Wash cycle time is longer than usual.

The washer automatically adjusts the wash time for the amount of laundry, water pressure and other operating conditions.

  • 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

Detergent compartments clogged from incorrect filling.

  • 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.

Too much detergent used.

  • Make sure that the suggested amount of detergent is used according to 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. HE (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 the washer.

Insufficient water supply

Inside of the drum was not cleaned properly.

  • Run the Tub Clean cycle regularly.

Odor

Problem Possible Cause & Solution

Odor

Some odor is caused by the rubber attached to the washing machine.

  • This odor is normal for new rubber and will disappear after the machine has been run a few times.

If the rubber door gasket and door seal area are not cleaned regularly, odors can occur from mold or foreign substances.

  • Be sure to clean the gasket and door seal regularly and check under the door seal for small items when unloading the washer.

Odors can occur if foreign substances are left in the drainage pump filter.

  • Be sure to clean the drainage pump filter regularly.

Odors can occur if the drainage hose is not properly installed, causing siphoning (water flowing back inside the washing machine).

  • When installing the drainage hose, be sure that it doesn’t become kinked or blocked.

Using the dry function, odors can occur from lint and other laundry matter sticking to the heater. (Dryer model only)

  • This is not a malfunction.

A particular odor can occur from drying wet clothes with hot air. (Dryer model only)

  • The odor will disappear after a short while.

Wi-Fi

Problem Possible Cause & Solution
Trouble connecting appliance and smartphone to Wi-Fi network

The password for the Wi-Fi network was entered incorrectly.

  • Delete your home Wi-Fi network and begin the connection process again.

Mobile data for your smartphone is turned on.

  • Turn off the Mobile data on your smartphone before connecting the appliance.

The wireless network name (SSID) is set incorrectly.

  • The wireless network name (SSID) should be a combination of English letters and numbers. (Do not use special characters.)

The router frequency is not 2.4 GHz.

  • Only a 2.4 GHz router frequency is supported. Set the wireless router to 2.4 GHz and connect the appliance to the wireless router. To check the router frequency, check with your Internet service provider or the router manufacturer.

The appliance and the router are too far apart.

  • If the appliance is too far from the router, the signal may be weak and the connection may not be configured correctly. Move the router closer to the appliance or purchase and install a Wi-Fi repeater.
