2-2. How to Detect Laundry Weight
• This product detects 5 levels of laundry weight.
• Laundry weight detection is for pre-wash and spin-dried weight; the detected laundry weight
data is used for:
- Pre-wash laundry weight detection (prior to initial water supply): To determine the wash
duration and the remaining time
- Spin-dried laundry weight detection (after draining and prior to spin-dry): To determine the
spin-dry algorithm and unbalanced state
2-3. Water Level Control
• This product is equipped with a sensor-type pressure switch that detects the water level in the drum while
water is supplied into the drum via the water supply valve and a sensor-type flowmeter that supplies the
measured amount of water.
• Once a certain amount of water is supplied via the flowmeter, the microprocessor detects the water amount
and stops water supply to start washing.
(If the water level is reduced as the laundry is wet, water supply resumes up to the appropriate level.)
• Upon drainage via the drain hose, the air pressure of the switch is reduced, and the lowered water level is
detected. After a certain period passes, spin-dry is initiated.

6
2-6. Condition for Door Lock Icon and Pop-up Display
• The water level frequency is 23.2 kHz or lower (display off when the water level frequency is
23.4 kHz or higher)
• The in-tub temperature is 45 degrees or higher, and the water level frequency is 24.6 kHz or
lower (display off when the in-tub temperature is 40 degrees or lower and the water level
frequency is higher than
24.6 kHz)
2-7. Button Lock Feature
2-9. Smart ThinQ (Wi-Fi feature)
• This feature prevents children from changing the preset mode accidentally during the wash.
- This feature is enabled/disabled with the "Screen lock" icon on the Settings window.
- This feature may be selected even when the motor is not in operation.
- Once the "Screen lock" is enabled, no button is operated except the Power button.
• While the Screen lock icon is displayed on the Settings window, no button is operated except the Power button.
If you download and install the smartphone app, you can use various features, e.g., remote
control, smart alert, mode download, and smart self-diagnosis.
• To use the Wi-Fi feature, please install the app, register your product, and complete your Wi-Fi
network setup process.
• Wi-Fi connection may not be available depending on your home network setup. For issues in
this regard, please contact your Internet service provider or network admin.
2-4. Door Open Control
• Once the program is closed, the door lock is released, and you can press the door handle to open
it.
• When you pause the product, the drum operation stops, and the door lock is released and may
be opened if the water level frequency is 23.4 kHz or lower and the in-tub temperature is below
a certain level (45℃).
• During power outage, within 5 minutes of power down, you can open the door. (If the in-drum
water level is above a certain level, the remaining water removal hose cap [CAP, COVER
(REMAINING HOSE)] should be removed before water can be removed.)
2-5. The door cannot be opened if:
• The power is down, or the power plug is removed
• The product is in operation

leveling feet of the Mini Washer and
the floor.
• Check whether the front-loading washer
moves when you shake it.
• If a leveling foot needs to be loosened by
10 mm or more, place a height adjustment
plate underneath. (Height adjustment
plates are sold at LG Electronics service
centers.)
2
Adjust the four leveling feet so that
all of them are firmly standing on the
floor.
3
Once level adjustment is done,

1. Unfasten the adapter ring plate and the 4 adapter retaining screws.
2. Push the adapter onto the end of the tap so that the rubber seal forms
a watertight connection. Tighten the adapter ring plate and the 4
screws.
3. Push the water supply hose vertically upwards so that the rubber
packing in the hose connects fully to the tap and then
tighten it by fastening clockwise.
• Water supply pressure must be between 100 kPa and 1000 kPa (1.0 ~ 10.0 kgf / cm
2
)
• Do not strip or crossthread when connecting inlet hose to the valve.
• If the water supply pressure is more than 1000 kPa, a decompression device should be installed.
• Periodically check the condition of the hose and replace the hose if necessary.

Step3: Connect hose to washer
• Make sure that the hose is not kinked or crushed.
ඖ
When your washer has two valves.
• The inlet hose with the red connector is for the hot water tap.
• If the washer has two valves, energy is saved by using the hot valve.
After connecting inlet hose to water tap, turn on the
water tap to flush out foreign substances (dirt, sand or
sawdust) in the water lines. Let water drain into a
bucket, and check the water temperature.

14
Connect Drain Hose.
Connect power plug.
If the drain hose is not installed properly, the unit will not drain properly.
This allows water to flow back into the unit which can cause odors.
Refer to owner’s manual for proper drain hose installation.
The odor could also be coming from the home’s drain to which the drain hose is attached.
In this type of drain hose installation, the odor could be coming from the standpipe.
This odor can come up the drain hose and into the unit.
Pour a cup or two of bleach or vinegar down the home drain
and let it sit for 24 hours before running another cycle.
This will help eliminate odor from the home drain.
If a cycle is started too soon after doing this, it will not help the issue.
Connect the power plug to the wall outlet. Avoid connecting several electric devices,
it may be the cause of a fire.

Using the level, level the washing machine from front to back and side to side.
Step 2
Use the spanner wrench to adjust legs until level and try the Diagonal test.
Step 3
Perform a Rinse and Spin with some clothing in the machine.
To do this, put 2~3kg of clothing in the unit, turn on the unit, select the Rinse+Spin
and then start. When the unit reaches the spin cycle, check vibrations.
If the unit vibrates, adjust the leveling foot slightly until the vibration subside. (Repeat step 2)
Step 4
Tighten the lock nut up to lock the positioned leg.
Lower the foot until there is no gap between floor and foot.
And only use adjustment rubber when the gap is more than 10mm.
Place your right hand on the back, right corner and your left hand on the front,
left corner of the unit, then attempt to rock the unit from corner to corner.
Then, move your right hand to the front, right corner and your left hand to the
back, left corner and attempt to rock the unit from corner to corner.
If the unit is level, it will not rock. However, if the unit is not level, it will rock.
If the unit rocks, it will be necessary to adjust the leveling feet of the unit.
Adjust the foot on the front right corner.
