Frequently Asked Questions - WW172EP LG

How often should I replace the filters?
Replace the Out Sediment filter after 3000 liters and other filters (Sedi+Carbon, RO, Mineral Booster) after 6000 liters of purification, or when the filter change indicator turns amber. Actual frequency depends on water quality and usage.
Why does the water taste strange?
If the purifier has not been used for 2 or more days, the water may taste stale. Discharge the tank once. Also check if filters are expired; replace if needed.
What should I do if no water comes out?
Ensure the water supply valve is open, the power plug is connected, and the filters are not clogged. If the issue persists, contact LG service.
How do I clean the water tank?
Close the water supply, drain the tank, unplug, open the top cover, wipe with a soft cloth using only purified water (no chemicals), rinse, reassemble, and run a full tank discharge before use.
What does the UV indicator mean?
Blue indicates UV sterilization is ON; white indicates OFF. The UV LED operates for 75 minutes every 6 hours and after power restoration. It automatically turns off when the tank cover is opened.
Can I install the water purifier myself?
Installation should be done by an authorized LG service center. Improper installation may cause electric shock, fire, or water leakage.
What is the recommended water pressure?
Water pressure should be between 10 and 860 kPa (0.1 to 8.8 kgf/cm²). The internal operating pressure is approximately 680 kPa before filtration.
How do I reset the filter change indicator?
After replacing the filter, the indicator may reset automatically. If not, contact LG service. The manual does not specify a manual reset procedure.
What does the flow sensor do?
It detects water flow. If no or low water supply is detected, the purifier stops for 15 minutes and then checks again. To restart immediately, turn power off and on.
Is it safe to use the purifier after a power outage?
Yes. After power returns, the UV LED will operate for 75 minutes to sterilize the water. It is safe to use after the tank is filled and discharged if it has been unused for over 2 days.

Water Reservoir Tank Over 1 Metre Water Purifier

Installing water purifier

1 Connect the product hoses as shown below.

  • Connect the white (water supply) hose to tap water.
    • Install the blue (drain) hose on the sink.

White Hose Blue Hose

2 Connect the power cord to an appropriate socket.
3 Open the water supply valve.
4 After installation, discharge water for the first time when water tank is full. Same process is to be followed after every filter change or digital sterilization. Appropriate time taken to fill the tank to the fullest is 1 hour, depending on water pressure, temperature etc.

CAUTION

Handle all packaging materials (such as plastic bags and thermocol) to keep away from children. The packaging materials can cause suffocation.

Important Note: All models can only be installed with water supply from overhead storage tank. No other water supply should be used for installation of these models.

Notes for Operation

  • Open the water supply valve. The water purifier operates normally only when water is supplied properly.
  • It is very important to replace the filter periodically in order to drink clean water. When using an expired filter, the performance of water filtration system can deteriorate. Always abide by the filter replacement period.

• If product has not been used for 2 or more days, discharge the stored water from water purifier tank.

- Do not use purified water for replacing water in the humidifier or fishbowl.

- Use the product only after closing the product cover completely. Otherwise, insects or other foreign substances may get in.

Note

• The reverse osmosis contains a replaceable treatment component critical for the effective reduction of total dissolved solids and that product water shall be tested periodically (during service engineer visit) to verify that the system is performing properly.
- Do not use with water that is microbiologically unsafe or of unknown quality, without adequate disinfection before or after the system.

Recommendation (when product not in use)

• If the Product will not be used for 2 or more days, unplug the power plug and close water supply valve before leaving premises and drain the water inside of water filtration(including tank) system completely before consumption of water.

Maintaining the filter

Process of Purification Drinking water

Step 1:

Out sediment filter with anti scalant module

- Removes big particles, rust stains, mud etc. and reduces input water hardness to enhance filter life.

Step 2:

Sedi + Carbon filter

• Removes unseen dregs and other contamination & removes invisible fine particles, residual chlorine, VOC (Volatile Organic Compounds) etc.

Step 3:

RO membrane filter* / RO recovery plus*

- Removes dissolved impurities and removes heavy metals, bacteria, viruses, VOC etc. from water.

• TDS Reduction upto 90% ppm of Source Water.

Step 4:

(For WW130/145/150/152/162 models)

Post-carbon filter

- Removes odour & improves taste of water.

(For WW140/151/155/172/173/174/175/182/183/184 models) Mineral booster filter

- Removes odour, add minerals in the purified water without mixing impure water.

Cleaning water for fruits & veggies\*

(Only with WW182EP/WW183EPR/WW184EPB/WW184EPC)

Step 1:

Out sediment Filter with antiscalant module:

- Removes big particles, rust stains, mud etc. and reduces input water hardness to enhance filter life.

Step 2:

UF membrane filter*

- Removes only bacteria and fine particle substance.

Step 1 → Step 2

NOTE

  • Do not use water drained from the product for drinking or cooking.
  • Use the water instead for cleaning the bathroom and house, gardening or for other various purposes.
  • Activated carbon inside the filter may sometimes flow in the storage tank. If so, a fine powder of activated carbon used in the post-carbon filter has come out, and it is harmless to the human body. If found, drain out the water from tank completely.

* For selected models only

** As per LGEIL standard.

Filter replacement period

The filter replacement period refers to the period that the purification performance of the filter is maintained. And, the replacement period is lesser in the case of a place with poor water quality or a large purification amount.

Filter nameRecommended purification amount**(in litres)
Out sediment filter3000
Anti scalant module6000

WARNING

  • Filter replacement and /or AMC request can only be placed via calling LG customer care (Refer last page)
  • Warranty shall be void in case of use of Counterfeit (duplicate) filters or replacement of filters from Unauthorized sources.
  • Using Counterfeit filters or procuring filters from unauthorized sources may negatively impact or degrade product performance and product life. It may not be safe drinking water and may also impact user's health.
  • LG shall not be responsible for any damage arising directly or indirectly out of any defect being noticed in the product due to usage of such Counterfeit filter's.

NOTE

If you wish to replace the filter, contact LG electronics customer care

• After replacing the filter, check if there is a leak from the product.
• After installation, discharge water for the first time when water tank is full. Same process is to be followed after every filter change or digital sterilization. Approximate time taken to fill the tank to the fullest is 1 hour, depending on water pressure, temperature etc.
- For RO Membrane Filter, around 25% of supplied water (based on the tap water pressure of 3.5kgf/cm2 at water temp. of 25°C) will be purified. While for RO Recovery Plus, around 50% (WW162EP/WW172EP/WW173EPB/WW182EP/WW183EPR) / 60% (WW174NPC/WW174NPB/WW175EPW/WW184EPB/WW184EPC) of supplied water (based on tap water pressure of 1.5Kgf/cm2, 750ppm TDS at water temp. of 25°C) will be purified and remainder will be drained.
- CAUTION: Outsediment filter may get choked in abnormal turbidity (Sand & mud) condition, it is suggested to switch ON water purifier after 1-2 hour of overhead tank filling so that sand/mud will get settled. Outsediment filter should be cleaned regularly to prevent choking in above condition for better performance.
