Leaking Front Load Washer Troubleshooting Guide

Leaking issues in front load washers can be resolved easily without a technician. If your machine is a top load washer, please visit our article on Leaking - Top Load Washer. The first step towards stopping the leakage is to discover the source.

Watch this instructional video to learn about How to Correct Leaking Issues.

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.

To fix this:

You need to clean the detergent dispenser properly; this simple step is mostly underestimated. Tiny debris, which are not easily visible do not take much effort to prevent proper dispensing, and cause the compartment to overfill and leak.

The steps are also performed in our instructional video on Play Video How to Prevent Leaking Issues.

  1. Remove the detergent dispenser

    Pull out the dispenser towards you until it stops. Locate the depressed tab between the bleach and softener compartment. While pushing down on the tab, pull the detergent tray out from the washer.

    After removing the dispenser tray, look inside the compartment to see if anything is obstructing the flow of water into the drum.

    Remove the detergent dispenser
  2. Rinse and clean with water and brush.

    Once the detergent dispenser is removed from the washer, disassemble the inserts from the tray, and clean each of the components with warm water, and a soft bristle brush.

    rinse the dispenser with water
  3. Replace the dispenser back.

    After the detergent dispenser is cleaned and rinsed, re-assemble the inserts, and replace the detergent dispenser into the washer.

    Replace the dispenser back

Leaks from Main Door

Go Back

Door leaks are caused by reasons most overlooked, such as hair, lint or residue on the gasket or the inside door glass. The most severe cause of door leakage is when your gasket is damaged; this will lead to excessive leakage from the door. Please visit our Request a Repair page for a professional service to replace a torn or damaged gasket.

How to fix main door leaks:

  1. Get a paper towel or washcloth.

    Towel & Wash Cloth
  2. Get bleach or vinegar.

    Dilute 3/4 cup of bleach with 1 gallon of warm water. Use vinegar in place of bleach if desired.

    Get bleach
  3. Clean the door-gasket.

    Using a cloth and the cleaning solution; clean the surface of the door-gasket. Pull the lip of the gasket back and clean its underneath part as well.

    Note: Do not use straight bleach to clean the gasket, this can cause the gasket to deteriorate over time.

    clean door gasket
  4. Clean the door.

    Wipe the inside door gently, from top to bottom, and around to the other side, but spend more time to wipe the round edge where the door meets the frame.

    wipe the door edge
  5. Remove hair, lint and residue.

    When cleaning the inside of the door, pay extra attention to the bottom of the door where hair, lint and residue can accumulate.

    remove residue
  6. Run tub cycle.

    If you see any hair, fabric thread or residue, remove it; run a tub cycle on your machine to check if the leakage 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. To order replacement parts, visit our Parts and Accessories page.

Leaks from Drain Pump Filter

Go Back

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

  • If the manual drain hose cap is loose; and

  • If the drain filter is not seated or screwed properly.

For your convenience, watch this interactive video about Play Video Cleaning the Drain Pump Filter.

  1. Turn off the washer.

    Press the POWER button to turn the washing machine off, and remove the plug from the outlet.

    turn off washer
  2. Service panel.

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

    service panel
  3. Unclip the drain hose.

    The drain hose is located beside the drain pump, Unclip it, and remove the plug (cap) from the drain hose to drain the water remaining inside a wash tub.

    Inspect the drain hose to ensure its not cracked or damaged.

    Note: Do not pull the hose too far out, it will kink the hose, and prevent the water from draining out.

    unclip the drain hose
  4. Remove the drain filter.

    Drain the excess water into a short bucket or shallow pan. After all the remaining water is drained from the drain hose, twist the pump filter counter-clockwise to remove it from the washer.

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

    remove drain filter
  5. Clean pump filter.

    Clean the pump filter with a soft-bristle brush with warm water. Do not wash the pump filter inside the dish washer.

    clean pump filter
  6. Clean the base.

    Clean the drain filter opening and it's base on the washing machine with a soft-bristle brush to remove debris.

    clean the base
  7. Return drain hose.

    Place the cap back into the drain hose, and re-attach the hose to the washer.

    Ensure that the drain hose is pushed in all the way back. It should not be split, cracked or damaged.

    return drain hose
  8. Return drain pump filter.

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

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

    return drain filter

If the drain hose or filter are damaged; or both are securely closed, but the leak 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.

Leaks from Safety Air Vent

Go Back
safety air vent

Though it sounds funny, leaks here are usually due to excessive use of detergent; new models of washers are built to use a little quantity of water and detergent, unlike the older washers.

We strongly recommend that you check our detailed article on Detergent and Additive Usage. You will be surprised to discover that leakage from safety air vent is mostly attributed to detergent usage.


  1. What type of detergent do you use?

    Use HE (high efficiency) detergents only.

    Beware:

    Concentrated HE: We do not recommend using concentrated varieties of HE detergent; because they can be easily overused. They can leave a residue inside the machine which builds up, causing the unit to leak from the safety air vent.

    Non-HE: Avoid using non-HE detergents, your machine is built to use less water, using these detergents will result to "too much detergent," that will eventually cause leakage from the safety air vent.

    HE detergents only
  2. How much detergent do you use?

    Follow the detergent manufacturer's recommendation, reduce the quantity whenever you notice suds. It may be necessary to reduce more if you still see suds.

    Beware:

    We do not recommend fill to normal or max line mark on your machine. For some detergents, you only need to use 1 - 2 tablespoons.

    The max line is simply the maximum amount that can be dispensed from the compartment before overfilling. All detergents are made differently, so the amount used should always start with what they recommend, and then reduced by half.

    Recommended Amount
  3. Do you use fabric softener?

    If you must use fabric softener, dilute the softener with water in ratio 50/50.

    Beware:

    Avoid filling the softener to the max line; softener should be used sparingly to prevent it from leaving a residue that causes leaking.

    fabric softener
  4. How often and what do you use for tub cleaning?

    NOTE: If you have NOT been performing tub cleaning, that may be the cause of the leakage. It may be necessary to perform tub cleaning three times back to back to break down the buildup and really clean it out. Buildup does not happen after one or two cycles, but after multiple cycles without tub cleaning, so one tub cleaning can only remove some of the buildups but not all.

    Perform tub clean at least once per month, or more often, using a tub cleaner. Bleach or vinegar is okay, but they are not as effective at removing buildup as a tub cleaner.

    Beware: Avoid using bleach and vinegar together.

    Tub Clean

Important tips to remember:

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

  2. Use only HE detergent, which is formulated for your HE washing machine.

  3. Since detergents are formulated differently, use the amount recommended by the detergent manufacturer. If you see suds, use half the recommended amount.

  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, it may be necessary to use as little as 1-2 tablespoons, especially if you have soft water.

  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.

Inlet Hoses and Valves

Go Back

Leaks from inlet hoses are mainly caused by two reasons:

PART 1 - Inlet Hoses and Rubber Seal

  1. Inspect inlet hoses.

    Prepare to inspect the two ends of the inlet hose, where it connects to the HOME VALVE and the WASHER, as shown in step 2 and 3 below.

    inspect inlet hoses connection
  2. Inspect connection to home valve.

    Inspect the inlet hoses connected to the home valve. Check if it is wet at the end of the connections.

    Check if the inlet hoses are kinked, punctured or visible traces of leaks around them.

    inlet connected to home valve
  3. Inspect connection to back of machine.

    Inspect the inlet hoses connected directly to the back of the machine. Check if it is wet at the end of the connections.

    Check the length of the hose for damage, also check for holes or any visible traces of leaks around the inlet hoses.

    check rubber seals
  4. Check the rubber seal.

    If either or both of them is wet, turn off the valve, remove the inlet hose, and check the rubber seal at the end of the hose.

    replace inlet hoses
  5. Replace seal and inlet hoses if necessary.

    If the seals are worn or damaged, find the same size replacement of rubber seals, or replace the hoses completely. You can find replacement hoses on our Parts and Accessories page.

    If not, re-attach the inlet hose, and endeavor to thread it correctly. Turn valve back on, and check for leaks again. If the leak continues, you need to replace the hose.

    replace rubber seals

NOTE: If inlet hose connected to the HOME VALVE has been replaced and the leak persists, contact your plumber. If the hose has been replaced and leak persists from the BACK OF THE MACHINE, the unit requires a repair service. Please visit our Request a Repair page for a professional service.


PART 2 - Clogged Filters

Clogged filters may not allow water to flow properly, causing back pressure, which could lead to leaks.

To clean the inlet filters:

  1. Turn the water off at the wall valves.

    Turn off home drain
  2. Disconnect inlet hose.

    Disconnect the inlet hose(s) from the back of the washer.

    disconnect inlet hose
  3. Remove inlet filter.

    Use needle-nose pliers, or some other grabbing tool with small tips, and pull the filters out of the inlet valves.

    remove filter out
  4. Remove buildup.

    Wash thoroughly in warm water until all signs of build-up are gone.

    Wash the inlet hose

If you have checked all of the options above and the leak 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.

Leaks from Drain Hose

Go Back

Leaks from the drain hose at the back are normally caused by the factors listed below; but if you see a hole or crack on your drain hose, a repair service is requested to replace it permanently to stop the leakage.

  • Drain hose not secured properly to the home drain.

  • The drain hose is secured, but the home drain is overflowing.

  1. Inspect drain hose.

    Locate the drain hose at the back of the machine, check if it is properly inserted to the home drain, or if it has come out, re-secure the hose properly.

    Inspect length of drain hose for holes, kinks or cracks.

    Drain hose at back of machine
  2. Look for an evidence of overflow.

    Look around the home drain for an evidence of overflow, such as water marks on the wall. If there is huge water overflow from the drain, the drain line may not be large enough(in diameter) or may have some buildups restricting the line. You will need to contact a plumber for proper adjustment.

    Evidence for overflow
  3. Check for clogs.

    If the water is leaking from the drain hose area, it may be clogged:

    You can confirm it by using a gallon of water. Pour the gallon of water into the drain and watch it reaching the top.

    If the whole gallon drains without leaking, your drain is probably fine. You may need to make sure the drain hose is properly installed in this case.

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

    Check for clogs

Important tips to remember:

  1. Make sure the drain hose is properly installed.

  2. Make sure the drain hose is not stretched, pinched, crushed or kinked.

  3. Make sure the drain hose is not air-tight inside of the drain.

  4. Check for a clogged drain.

If there is no overflowing from the home drain, but the leak is coming from the washer (not the wall or the hose), the unit requires a repair service. Please visit our Request a Repair page for a professional service.

Leaks from Underneath the Washer

Go Back

Leaks that appear to come from underneath the washer are often coming from the door, or a safety air vent, at the back of the unit.

Apparently, the leak must have started during the washing cycle, but the leakage accumulated underneath the washing machine.

View how to stop leakage from the either of the two options below:

Door Safety Air Vent
Leakage from underneath

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?

  9. 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 our Drain Pump Filter section to rectify this problem.

  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.

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 troublesshoot 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.

Do you know where the leakage is coming from?

Yes, Proceed No, I Don't Know
