An LG washing machine that leaks during the drain cycle can quickly turn a routine laundry day into a cleanup problem. You may notice water pooling around the front or back of the appliance, damp flooring beneath the cabinet, or water dripping from a connection near the drain hose. In many cases, the leak is related to the drain pump, a loose hose connection, or a damaged component in the drainage system.
Because the leak often appears only when the washer removes water, identifying exactly when it happens can help narrow down the possible cause. Addressing the problem early can prevent water damage to flooring and nearby cabinets while reducing the risk of additional washing machine repairs.
Why Does the Leak Happen During Draining?
During the drain cycle, the washing machine’s pump pushes used water out of the tub and through the drain hose. This process creates water movement and pressure within the drainage system. If a hose connection is loose, a seal has deteriorated, or the pump housing is damaged, water may escape while the machine empties.
A washer can complete its wash cycle without leaking and still develop a noticeable puddle during draining. This pattern is an important diagnostic clue because it suggests that the problem may be associated with components that handle wastewater.
However, the timing alone does not confirm which part has failed. A technician may need to inspect the drainage system to identify the source.
Possible Cause 1: A Faulty Drain Pump
The drain pump is responsible for removing water from the washing machine after washing and rinsing. Over time, its housing, seals, or internal components may wear out. A crack in the pump housing or a deteriorated seal can allow water to escape when the pump operates.
Other symptoms may accompany the leak. You might hear unusual buzzing, grinding, or humming during draining. The washer may also drain slowly, stop before completing the cycle, or leave water inside the drum.
A blocked pump filter can sometimes contribute to drainage problems. Coins, lint, hair, and other small objects may accumulate in the filter, restricting water flow. Although a blockage does not automatically mean the pump is leaking, it can be part of a broader drainage issue that requires inspection.
If the pump itself is damaged, cleaning the filter will not solve the problem. The faulty component may need to be replaced.
Possible Cause 2: A Loose or Damaged Drain Hose
The drain hose carries wastewater from the washing machine to the household drain. If the hose becomes loose, develops a crack, or suffers damage near a connection point, water may leak whenever the washer pumps water out.
Inspect the visible section of the hose for signs of moisture, splits, kinks, or loose fittings. Pay particular attention to the connection at the back of the appliance and the point where the hose enters the household drain.
A hose may also become displaced if the washing machine moves during operation. Strong vibration can gradually affect connections, particularly when the appliance is not level or the load is unbalanced.
If the hose is cracked, replacement is generally more reliable than attempting a temporary repair. Loose connections should be secured according to the manufacturer’s instructions, without overtightening fittings or damaging the hose.
Possible Cause 3: A Clogged Drain or Restricted Water Flow
A partially blocked household drain can interfere with wastewater removal. Water may back up around the drain opening, overflow, or escape near the hose connection.
This type of problem can be mistaken for a leaking washing machine because the water appears while the appliance is draining. Check whether water collects around the standpipe or nearby plumbing rather than directly beneath the washer.
If the household drain is obstructed, repairing the washing machine alone will not resolve the underlying issue. The drain may need to be cleared or inspected by a qualified plumbing professional.
Possible Cause 4: A Worn Seal or Damaged Internal Hose
Washing machines contain internal hoses that connect the tub, pump, and other drainage components. These parts can deteriorate, loosen, or become damaged after years of regular use.
A leak from an internal hose may be difficult to locate because water can travel along the bottom of the cabinet before reaching the floor. As a result, the visible puddle may not be directly beneath the damaged component.
Seals and gaskets can also deteriorate over time. If an internal connection is responsible, accessing it may require removing parts of the washer’s cabinet. A professional inspection can help distinguish between a failing seal, a damaged hose, and a defective pump.
What Should You Do If Your LG Washer Is Leaking?
If you notice water during the drain cycle, stop using the washing machine until the source has been identified. If it is safe to do so, switch off the appliance and disconnect power only when the plug and surrounding area are dry. If water is near electrical connections, avoid touching the appliance or plug and use the appropriate electrical isolation method from a safe, dry location.
Turn off the water supply if necessary and clean up standing water to reduce the risk of damage. Do not pull the washer away from the wall if doing so would expose you to water near electrical components.
You can inspect visible hose connections and look for obvious signs of damage without dismantling the machine. Before checking any accessible filter, consult the owner’s manual, disconnect power, and prepare for residual water to drain out.
Avoid repeatedly running the washer to reproduce the leak. Additional cycles may allow more water to escape and increase the damage.
When Should You Call an Appliance Repair Technician?
Professional service is recommended when the leak continues, the source is hidden, the drain pump makes unusual noises, or the washer fails to drain properly. A technician can inspect the pump, hose connections, internal drainage hoses, seals, and related components to determine what needs attention.
Accurate diagnosis matters because replacing the pump will not fix a leaking hose, and tightening a connection will not resolve a cracked pump housing. Identifying the actual cause helps prevent unnecessary part replacements and repeat service calls.
Regular maintenance can also reduce the likelihood of drainage problems. Clean the accessible filter according to the manufacturer’s recommendations, avoid overloading the washer, and check visible hoses periodically for wear or damage.
