Leaking Front Load Washer Troubleshooting Guide

You may see water leaking from your washer bottom, door, detergent dispenser, hoses or other locations. Leaks from an LG washer are often easily resolved without a technician’s support. The first step toward fixing a leaking washing machine is to discover the source of the leak. After you have inspected the unit and identified the source, select an option from the list below.

If your machine is a Top Load Washer, please visit our article on How to Fix a Leaking Top Load Washer.

Leaks from Detergent Dispenser

Go Back

Dispenser leaks are normally caused by the following:

  • Obstruction in the dispenser or dispenser compartment.

  • Detergent or additive buildup in the dispenser.

This can be resolved by cleaning the dispenser drawer. Debris or additive buildup can prevent detergent from dispensing properly and cause the compartment to overfill and leak.

  1. Remove the detergent dispenser

    Fully extend the detergent dispenser drawer outward.

    Press down the PUSH button between the bleach and fabric softener compartments to release the detergent dispenser drawer.

    Carefully remove each compartment (lift the front side first as the tabs on the rear are delicate).

    Remove the detergent dispenser
  2. Clean the compartments and the dispenser drawer.

    Carefully remove each compartment (lift the front side first as the tabs on the rear are delicate).

    Once removed, wash thoroughly by hand with warm water and a soft sponge or towel to remove excess detergent or residue buildup.

    Use a wet towel or soft sponge to wipe away any detergent residue buildup inside the detergent dispenser drawer cavity.

    Once completed, let the compartments and drawer completely dry.

    rinse the dispenser with water
  3. Reinstall the compartments and dispenser drawer back into the detergent cavity.

    Reassemble the compartment inserts and replace the detergent dispenser drawer back into the washer.

    Replace the dispenser back

Leaks from Main Door

Go Back

Door leaks are caused by buildup of hair, lint or residue on the gasket or the inside door glass. Leaking can happen if the door gasket is damaged, leading to excessive leakage from the door.

How to fix main door leaks:

  1. Inspect the door gasket for tears or damage.

    NOTE: If torn or damaged, please visit our Request a Repair page to arrange for a professional repair tech to come out and replace the gasket.

    remove residue
  2. Clean the door and door-gasket.

    NOTE: DO NOT use straight bleach to clean the gasket, as this can cause the gasket to deteriorate over time.

    While wearing gloves, mix a cleaning solution of 3/4 cup bleach OR vinegar to 1 gallon of water.

    Wipe the inside door gently, from top to bottom, and around to the round edge where the door meets the gasket.

    With a cloth and the cleaning solution clean the surface of the door gasket.

    Pull the lip of the gasket back and clean underneath the lip of the gasket as well.

    Note: When cleaning inside the gasket, be mindful to clean out any hair, lint, and/or detergent buildup.

    clean door gasket
  3. Run tub cycle.

    If you see any hair, fabric threading or residue build up, remove it and run a tub clean cycle on your washing machine to check if the leaking stopped.

    If the rubber gasket is torn or damaged, or the door and gasket are clean but the leak persists, the unit requires a repair service. Please visit our Request a Repair page for a professional service.

    run tub cycle

Leaks from Drain Pump Filter

Go Back

Leaks from the drain filter are normally caused by two reasons:

  • The manual drain hose cap is loose.

  • The drain pump filter is not seated or screwed on properly.

  1. Turn off the washer.

    Press the POWER button to turn off the unit and unplug it from the outlet.

    turn off washer
  2. Locate the service panel for the drain pump filter.

    Find the service panel (drain filter area) located on the bottom-left corner of the unit and open it.

    service panel
  3. Drain out the excess water.

    Inspect the drain hose to ensure it is not cracked or damaged.

    Unclip the hose to the left of the drain pump, remove the cap and drain the excess water into a bucket or shallow pan.

    Note: The amount of water may vary according to when in the cycle the leak occurred.

    unclip the drain hose
  4. Remove the drain filter.

    After all excess water has been drained, twist the pump filter counter-clockwise to remove it from the washer.

    remove drain filter
  5. Clean the drain pump filter and the base

    With a soft-bristle brush and warm water, gently clean out any hair, lint or detergent residue.

    Clean the filter opening and its base on the washing machine.

    clean pump filter clean the base
  6. Reinsert the drain hose cap and reattach the drain hose to the washer.

    Confirm that the drain hose is free of any tears, cracks or damage before reinserting the cap.

    Ensure the drain hose is securely installed completely back into the washer.

    return drain hose
  7. Reinstall the drain pump filter.

    Insert the drain pump filter back into the washing machine, making sure it is inserted securely.

    When inserting the filter, make sure it is threaded correctly and tightened. It should stop turning once it is securely tightened.

    return drain filter

Leaks from Safety Air Vent

Go Back
safety air vent

Leaks from the “safety air vent” on the back of the washer occur when detergent residue has built up in the wash tub and on clothing.

If water or suds are seen leaking from the safety air vent located on the back of the washer or if large amounts of suds are visible in the tub during the wash cycle, try the steps below:


  1. Confirm the detergent type.

    It is recommended you ONLY use HE (high efficiency) detergents.

    Concentrated HE detergent can leave a residue inside the machine which builds up and causes leaking from the safety air vent.

    Non-HE detergent will cause over sudsing, leading to detergent remaining in the tub after the cycle or leakage from the safety air vent.

    HE detergents only
  2. Reduce the amount of detergent and additives being used.

    NOTE: Depending on your brand of detergent, IT IS NOT recommended to fill the detergent dispenser to the max line mark. Some detergents only require 1-2 tablespoons.

    Follow the detergent guidelines from the manufacturer, however, it is recommended you reduce the amount used whenever suds remain after a wash.

    The max fill line on the dispenser only indicates the amount of detergent that can be dispensed from the compartment.

    If using fabric softener, it must be diluted with water to a 50/50 ratio.

    Beware: Filling the fabric softener compartment to the max line can leave residue that causes leaking.

    Recommended Amount
  3. Perform a TUB CLEAN cycle.

    A tub clean cycle should be performed at least once per month or more depending on wash frequency and the amount of detergent and additives being used.

    If it has been some time since the last tub clean cycle, it may be necessary to perform tub cleaning 3 times back to back to break down the buildup.

    Observe the unit for leaks after each tub clean cycle. If leaking persist after 3 tub cleans, please visit our Request a Repair page for a professional service.

    Tub Clean

Inlet Hoses and Valves

Go Back

Leaks from the washer’s inlet hoses are mainly caused by loose or misthreaded hose connections, slightly damaged hoses, damaged connector washers or clogged inlet filters.

  1. Turn off the water supply.


    Turn off home drain
  2. Inspect the inlet hoses.

    Ensure that the hoses are not kinked, cracked, punctured or have any visible traces of leaks around them.

    Look at both ends of the hoses, where they connect to the home valves and to the back of the washer.

    Check if there are wet areas at the end of the connections.

    If either or both are wet at the end of the connections, disconnect the inlet hoses and check the rubber washers.

    If the rubber washers are worn or damaged, replace the rubber washers inside the connections or on the inlet hoses.

    If the hoses and connectors look good, then you will need to check the inlet filters.

    inspect inlet hoses connection
  3. Disconnect inlet hose.

    Use needle-nose pliers or a similar tool to pull the filters out of the inlet valves on the back of the machine.

    Remove any buildup on the filters by washing them thoroughly with warm water and a brush

    Replace the clean filters in the inlet valves and re-attach the inlet hoses while being careful to thread them correctly.

    Turn the home water valves back on and check for leaks again. If the leak continues, you need to replace the hose.

    If you’ve replaced the hose and the leak persists from the home water valve connection area, contact your plumber.

    NOTE: If the leak persists from the back of the machine, please visit our Request a Repair page to schedule service.

    remove filter out

Leaks from Drain Hose

Go Back

Leaks from an LG washer are often easily resolved without a technician’s support, if the source can be identified.

If you have identified the source of the leak as the washer drain hose, try the steps below.

  1. Inspect the drain hose.

    Inspect the drain hose for any holes, cracks, or kinks and ensure the drain hose is properly inserted into the home’s drain.

    If you see a hole or crack, please visit our Request a Repair page to schedule service for the drain hose to be replaced.

    If the hose has come out, re-secure the hose properly.

  2. Inspect the drain area for evidence of overflow.

    If there is significant water overflow from the drain, the drain line may not be large enough in diameter, or it may have buildup restricting the line that needs to be removed.

    Evidence for overflow
  3. Check for clogs.

    Pour one gallon of water into the drain and watch it reaching to the top.

    If the water reaches the top and leaks over the edge, there is a clog. You can clear the clog by using a drain cleaner liquid, or you could call a plumber.

    If the whole gallon drains without leaking, the drain is probably fine. Make sure the drain hose is properly installed.

    Check for clogs

Leaks from Underneath the Washer

Go Back

Leaks that appear to come from underneath the washer are often coming from the door, safety air vent, or the back of the unit. The leak would have started during the wash cycle and accumulated underneath the washing machine.

Leaks from Underneath the Washer

Go Back

Leaks from an LG washer are often easily resolved without a technician’s support, if the source can be identified.

If unsure of the source of the leak, see the video below to identify the possible source of the leak.

Leaks from Unknown Area

Since you are uncertain about where the leak is coming from, you need to troubleshoot the machine. Do not panic; the troubleshooting steps below will guide you to identify the source of the leakage, and how to stop it.

Now, let's troubleshoot.

  1. Are you able to look around the side, or over the top of the washer, to see behind the unit?

    Yes No
  2. You may need a flashlight, in order to see the back of the unit properly.

    Inspect the length of the inlet hoses, including where they connect at the home valve and the back of the washer. You may need to check the detailed instruction about this from our Inlet Hoses and Valve section of this article.

    Is there any visible water on the hoses, connectors, or around this area?

    Yes No
  3. We just figured it out! The leak is coming from the inlet hoses. Proceed to our Inlet Hoses and Valve section to rectify this problem.

  4. Is the drain hose still secured in the home drain?

  10. At this stage we are left with two possibilities:

    • The leak may be coming from the door, if there is anything interfering with the watertight seal.

    • The leak may be coming from the safety air vent, that is mostly caused by detergent usage.

    • View how to stop leakage from the either of the two; by selecting from the options below:

      Door Safety Air Vent

    If you have tried everything, and the leakage persists, the unit requires a repair service. Please visit our Request a Repair page for a professional service. To order replacement parts, visit our Parts and Accessories page.

Our first stop is the detergent dispenser. Leakage from the dispenser can be a little bit hard to notice, when the leak occurs, the water flows from through the tiny pathway below the dispenser, to the door frame, and then to the bottom of the washer.

  1. Does this step stop the leaking?

    Yes No, Proceed to Next Step
  2. Good job, tiny debris go a long way to cause leakage, remember to always clean the detergent dispenser to avoid leaking from this area in the future.

  1. Does cleaning the main door stop the leaking?

    Yes No
  2. If you open the service panel, on the bottom left corner, is this area wet?

    Yes No
  3. We just figured it out! The leak is coming from the drain pump filter or manual drain hose inside the drain pump filter.

    Proceed to Drain Pump Filter
  4. Are you able to look around the side, or over the top of the washer, to see behind the unit?

    Yes No
  5. Is there any visible water on the hoses, connectors, or around this area?

    Yes No
  6. Good, the leak is coming from the inlet hoses or main drain. Our first stop is the inlet hose, we need to check it is properly connected and ensure that there are no damages to the inlet hose valves.

  7. This leak may be coming from the safety air vent at the back of the unit, if the washer is not inspected during a washing cycle (when the machine is ON), you may not be able to see flow of the leakage. But if the leak has been occurring consecutively for some time, you may be able to see traces of residue buildup on the safety air vent, at the back of your machine.

    Proceed to Safety Air Vent
  8. Good job, cleaning the main door for tiny debris and residue should become one of your maintenance habits, remember to always clean the main door once in a while with bleach or vinegar.

  1. Does this step stop the leaking?

    Yes No
  2. Good job, we have been able to stop the leak from the drain filter. Remember to always check this area for clogs, this will prevent leakage in the future.

  3. Are you able to look around the side, or over the top of the washer, to see behind the unit?

    Yes No
  4. Is there any visible water on the hoses, connectors, or around this area?

    Yes No
  5. Good, the leak is coming from the inlet hoses or main drain. Our first stop is the inlet hose, we need to check it is properly connected and ensure that there are no damages to the inlet hose valves.

  6. This leak may be coming from the safety air vent at the back of the unit, if the washer is not inspected during a washing cycle (when the machine is ON), you may not be able to see flow of the leakage. But if the leak has been occurring consecutively for some time, you may be able to see traces of residue buildup on the safety air vent, at the back of your machine.

    Proceed to Safety Air Vent

Since the accumulated buildup cannot be removed with immediate detergent adjustment and tub cleaning, it will take some time for the leakage to stop. We recommend that you check the remaining two leakage areas below.

Important tips to remember:

  1. Your machine uses little water, which makes it practically easier to use too much detergent.

  2. Use only HE (high efficiency) detergent, because some regular detergents do cause over-sudsing.

  3. Since detergents are formulated differently, read the detergent manufacturer's recommendation. It is advisable that you use less during each cycle.

  4. Keep reducing the amount of detergent until sud stops occurring.

  5. If sud persists, reduce the volume of detergent again, and run a washing cycle without detergent.

  6. For HE non-concentrated detergent, use no more than 1-2 tablespoons.

  7. For softeners, the recommended dilution is 50/50 dilution with water

  8. Perform regular tub cleaning at least once in a month to prevent residue buildup from detergent additives.

  9. For maximum cleaning of your tub, tub cleaners are more effective than bleach and vinegar.

When performing recurrent tub clean, observe each tub clean for leaks, if the leakage persists after three tub clean cycles, the unit requires repair service. Please visit our Request a Repair page for a professional service. To order replacement parts, visit our Parts and Accessories page.

  1. Does this step stop the leaking?

    Yes No
  2. Good job, we have been able to stop the leak.

  3. This leak may be coming from the safety air vent at the back of the unit, if the washer is not inspected during a washing cycle (when the machine is ON), you may not be able to see flow of the leakage. But if the leak has been occurring consecutively for some time, you may be able to see traces of residue buildup on the SAFETY AIR VENT, at the back of your machine. Otherwise, proceed.

    Proceed to Drain Pump

END OF TROUBLESHOOT

If you have tried everything on this troubleshooting guide and the problem still persist, the unit will require a repair service. Please visit our Request a Repair page. A technician will be assigned to check your problem for further troubleshoot and repair.

How to Perform Tub Clean Cycle

The tub clean cycle is a cycle that is pre-set with the optimum settings to clean the inside of the wash tub.

When the tub clean cycle is selected, the washer will run a hot wash cycle to clean the inside of the unit, followed by a high spin speed that helps to dry the inside of the drum.

To activate the tub clean cycle, press the tub clean button, and then press the START/PAUSE button.

Note: If the washer is not equipped with the tub clean cycle, use the SANITARY CYCLE instead.
