Why Is My LG Washing Machine Leaking Water?
Check and tighten the cold and hot water inlet hose connections at the back of the machine — loose fittings are the most common cause of leaks and re-tightening them by hand plus a quarter-turn with pliers usually stops the leak immediately (takes about 5 minutes).
Fault description
A leaking LG washing machine is one of the more alarming faults you can encounter, but in most cases the source is straightforward to identify and fix without specialist tools. Water may appear at the front, back, or underneath the machine, and the leak can occur at different points in the cycle — during filling, washing, spinning, or even when the machine is idle.
The leak typically originates from one of several areas: the water supply connections, the door seal, the detergent drawer, the drain hose, or internal components such as the pump or tub. On some LG models, an overflow condition will trigger the FE error code, which indicates the machine has detected too much water in the drum — this can itself cause water to escape through the door or overflow channels.
Identifying exactly where the water is coming from before you start any repair will save you time and help you target the right fix. Place a dry towel around the base of the machine, run a short cycle, and check where the towel becomes wet first.
Causes
- Loose or damaged inlet hose connections — The hot and cold water supply hoses connect to the back of the machine with threaded fittings. Over time these can loosen due to vibration, or the rubber washers inside the fittings can harden and crack, allowing water to drip or spray from the connection point.
- Worn or torn door seal (door gasket) — The rubber gasket that forms a watertight seal between the door and the drum is subject to constant flexing and exposure to detergent. Tears, holes, or a build-up of mould and debris can prevent it from sealing properly, causing water to leak from the front of the machine during a wash.
- Blocked or misaligned detergent drawer — If the detergent drawer is clogged with detergent residue or fabric softener, water can back up and overflow out of the drawer housing onto the floor. A drawer that has been pushed in at an angle can also break the water seal around the inlet jets.
- Damaged or incorrectly routed drain hose — A split, cracked, or loosely connected drain hose will allow water to escape during the pump-out phase of the cycle. If the hose is inserted too far into the standpipe or positioned too low, it can also cause a siphoning effect that leads to continuous slow leaking.
- Faulty door lock or door seal retaining spring — The door seal is held in place by a retaining spring or clamp band. If this spring snaps or slips out of position, part of the seal can pull away from the drum opening, creating a gap through which water escapes during the wash.
- Overfilling due to a faulty pressure sensor or inlet valve (FE error) — If the water inlet valve fails to close fully, or the pressure sensor that monitors water level malfunctions, the drum can overfill. LG machines will display the FE error code in this situation, and excess water will overflow through the door seal or the pressure chamber hose.
Step-by-Step Fix
- 1
Locate the source of the leak
Before touching anything, run a short wash cycle and observe where water first appears — front, back, underneath, or from the drawer area. Lay dry paper towels around the machine to pinpoint the exact location. Knowing the source will tell you which component to inspect first and prevents unnecessary disassembly.

Inspect and tighten the inlet hose connections
Turn off the water supply and pull the machine slightly away from the wall. Check both inlet hoses where they connect to the machine and to the tap. Hand-tighten any loose fittings, then add a quarter-turn with pliers. If the rubber washer inside the fitting looks flattened or cracked, replace it — these washers cost very little and are available at most hardware stores.
- 3
Clean and reseat the detergent drawer
Pull the drawer out fully (press the release tab if fitted) and rinse it under warm water to remove all detergent and softener build-up. Use an old toothbrush to clean the drawer housing inside the machine, paying attention to the inlet jets at the top. Reinsert the drawer carefully, making sure it slides in straight and clicks into place.
- 4
Examine the door seal for damage
Open the door and run your fingers around the entire circumference of the rubber gasket, feeling for tears, holes, or stiff sections. Also check the fold of the seal for trapped debris, coins, or glass that may have caused a puncture. Small tears can sometimes be temporarily sealed with waterproof silicone, but a damaged gasket should be replaced for a lasting repair.
- 5
Check the door seal retaining spring
Peel back the outer lip of the door seal and look for the metal or plastic retaining spring that holds it against the front panel. If the spring has snapped or slipped out of its groove, the seal will not sit flush. Reseating or replacing the spring is a straightforward job that requires no special tools — just take care not to overstretch the rubber gasket.
- 6
Inspect the drain hose at the back and at the standpipe
Pull the machine forward and trace the drain hose from the pump outlet to where it enters the standpipe or sink. Look for cracks, kinks, or loose jubilee clips. The hose should be inserted no more than 15 cm into the standpipe and the entry point should be at least 60 cm above floor level to prevent siphoning. Secure any loose clips and replace a cracked hose.
- 7
Run a test cycle and monitor for the FE error code
After completing the checks above, run a full wash cycle and stay nearby to observe. If the machine displays the FE error code and continues to fill without stopping, the water inlet valve or pressure sensor is likely faulty. At this point, further diagnosis requires accessing internal components and is best handled by a service technician.
When to call a service technician
If you have worked through all the steps above and the machine is still leaking, or if the leak is coming from underneath the machine and is not related to the drain hose, there may be a crack in the outer tub, a failed pump seal, or a split internal hose — none of which are practical DIY repairs. Similarly, if the FE error code keeps returning after you have checked the inlet hoses, the water inlet valve or pressure sensor will need to be tested with a multimeter and replaced if faulty.
You should also call a service technician if you notice water near any electrical components, if the machine trips your household circuit breaker, or if the leak is large and sudden rather than a slow drip. In these situations, continuing to run the machine risks both water damage to your home and a potential electrical hazard.
Prevention
The parts most commonly replaced when an LG washing machine develops a water leak are the door seal (gasket), the inlet hose washers or complete inlet hoses, and the water inlet valve. Keeping a spare set of inlet hose washers on hand is inexpensive and means you can fix a dripping connection in minutes. Replacing the door seal every few years — or sooner if you notice any stiffening or discolouration — is the best way to prevent front-of-machine leaks from developing.
To reduce the risk of leaks over time, use only the recommended amount of HE (high-efficiency) detergent, wipe the door seal dry after each wash to prevent mould growth, and check your inlet hose connections every six months for signs of wear. Avoid overloading the drum, as excessive vibration accelerates wear on hoses and seals.

Frequently Asked Questions
Why is my LG washing machine leaking from the front?
A leak from the front almost always points to the door seal (gasket). Inspect the rubber seal for tears, holes, or debris caught in the fold. If the retaining spring that holds the seal in place has slipped or broken, the seal will pull away from the drum opening and allow water to escape during the wash cycle.
What does the FE error code mean on an LG washing machine?
FE stands for Fill Error and indicates that the machine has detected too much water in the drum. This is usually caused by a water inlet valve that is not closing fully, or a faulty pressure sensor that is not accurately reading the water level. If you see this code, turn off the water supply and call a service technician to test and replace the faulty component.
Can I use my LG washing machine if it is leaking?
It is not advisable to continue using a leaking machine. Even a small leak can cause water damage to flooring and cabinetry over time, and if water reaches electrical components it creates a safety risk. Identify and fix the source of the leak before running another cycle.
Why does my LG washing machine only leak sometimes?
Intermittent leaks are often linked to specific cycle stages. A leak only during filling suggests an inlet hose or valve issue; a leak only during the wash or spin points to the door seal or tub; a leak only during draining indicates a problem with the drain hose or pump. Running a cycle while watching the machine closely will help you narrow down the timing and location.
How long does it take to replace a door seal on an LG washing machine?
Replacing a door seal typically takes between 30 and 60 minutes for someone with basic DIY confidence. You will need to remove the door, the front panel trim, and the retaining spring before the old seal can be pulled free. Make sure you order the correct seal for your specific LG model number, as the gasket dimensions vary between machines.
