What to Do When My Washer Is Leaking

A leaking washer — or a washer leaking water — creates an emergency: risk of water damage, damaged flooring, mold. The good news: the exact location of the leak almost always points to the diagnosis before a technician even arrives.

At Service 2000, our technicians have handled this symptom nearly 1,500 times between 2021 and 2025. Here’s how to read the situation before calling.

Key takeaways

• The leak location is the first useful clue — it directly points to the likely cause.
• The door gasket is the most common cause on front-load washers — about 21% of service calls.
• Internal hoses are responsible in about 18% of cases.
• The water inlet valve accounts for about 13% of service calls.
• In about 11% of cases, no part needs replacing — excess water pressure, too much detergent, or improper installation.
• Other causes (pump, dispenser, tub, motor): about 26% of cases combined.
• 94% of service calls for this symptom end with a completed repair.

What to Do Immediately When the Washer Is Leaking

Before calling, three steps to take in order.

1. Shut off the water supply. Close the water intake valves behind or under the washer. If the leak is active, this is the first thing to do to limit the damage.
2. Locate the leak. Watch during a cycle to see exactly where the water appears — through the door, under the machine, at the back, during fill, or during drain. This is the most useful detail to share with the technician.
3. Check the amount of detergent. Excess detergent creates foam that overflows through the door or the seals. Use only high-efficiency (HE) detergent in reduced amounts. If the leak disappears with less detergent, that’s the cause.

What Are the Most Common Causes Based on Leak Location?

Based on nearly 1,500 service calls for this symptom between 2021 and 2025, here’s what our technicians find depending on where the leak appears.

Leak Through the Door — Door Gasket

The door gasket is the most common cause on leaking front-load washers — about 21% of service calls for this symptom. This circular rubber seal ensures a watertight fit between the door and the drum. It tears, deforms, or develops holes over time, especially if hard objects — staples, zippers, coins — regularly pass through the machine. A moldy or deformed gasket can also fail to seal properly without visible damage. Check this visually first.

Leak Under the Machine or Midway — Internal Hoses

Internal hoses — the hose connecting the drum to the pump, the dispenser hose, the pressure hose — are responsible in about 18% of service calls. These hoses age, crack, or disconnect from their fittings. The leak often appears during spin or drain cycles, when pressure is highest. This type of leak isn’t visible from the outside — it requires access to the inside of the appliance.

Leak During Fill — Water Inlet Valve

The water inlet valve is responsible in about 13% of service calls. It controls the flow of cold and hot water into the machine. When it’s faulty, it can let water through continuously — even when the washer is off — or produce a leak at the back during filling. A valve that leaks slowly and continuously can cause water damage even between cycles.

Leak Through the Detergent Dispenser

The detergent dispenser and its hoses are responsible in about 7% of service calls. Foam overflow, a clogged dispenser, or a cracked hose produce a leak at the front top of the machine, often during fill. Cleaning the dispenser and reducing the amount of detergent sometimes fixes the problem without a service call.

Leak During Drain — Pump

The drain pump is involved in about 4% of leaks. A faulty pump seal or a foreign object that punctured the housing produces a leak under the machine only during drainage.

Leaks by Brand — What Our Data Shows

LG is the most represented brand for this symptom in our data — more than one in four service calls. The dominant cause remains the same: the door gasket, particularly on front-load models. If your LG washer is leaking through the door, that’s the first thing to check before calling.

When Should You Call a Technician?

Call without delay when:

• The leak is active and water is pooling on the floor — immediate risk of water damage
• The water inlet valve leaks even when the washer is off
• The leak is coming from inside the appliance and isn’t visually accessible
• The door gasket is visibly torn or punctured
• The leak appears during spin cycle along with an unusual noise — possible internal hose failure

Don’t use the washer if the leak is significant — water under a wood floor or in a basement can cause serious damage within a few cycles.

Repair or Replace a Leaking Washer?

Most washer leaks involve relatively accessible and inexpensive parts — door gasket, valve, hose. For an appliance under 10 years old in generally good condition, repair is almost always the right call. Beyond that, the decision depends on overall condition and estimated cost. Service 2000 will tell you plainly if the repair isn’t worth it.
