Washing Machine Leaking Water? Here’s Why (And What To Check)
Your washing machine is leaking water. Maybe it’s pooling underneath the machine. Maybe it’s running out from the door. Maybe it’s appearing at the back. Or maybe it only leaks during the fill, the drain, or the spin cycle.
The good news is that most washing machine leaks are caused by a handful of components, and the location of the water tells you which one. A leak from the door points to the door seal. A leak from the back points to a hose. A leak from the bottom points to the pump or a loose connection.
And in many cases, the fix is free or cheap. A loose hose connection, a filter that wasn’t tightened, or a worn door seal are the most common causes — and all three are affordable to fix.
This page covers the seven most common leak patterns, the symptoms to look for, and the checks you can perform yourself. If you need the complete diagnostic sequence with component testing and repair-or-bin guidance, the full guide is linked at the bottom.
Quick Diagnosis
Leaking from the bottom: a door seal, drain pump, or loose connection.
Leaking from the door: a failed door seal, door alignment, or debris on the seal.
Leaking from the back: a loose inlet hose connection or a cracked hose.
Leaking from underneath: a tub seal, pump seal, or internal hose.
Leaking during fill: an inlet hose or inlet valve.
Leaking during drain: a drain hose or pump.
Leaking during spin: a door seal or tub seal.
Why Your Washing Machine Leaks Water
A washing machine takes water in, uses it, and pumps it out. If any part of that path fails, water escapes.
Washing Machine Leaking Water?
The path works like this:
Water enters through the inlet hose and the water inlet valve
The water fills the drum through the detergent drawer and the dispenser
The drum holds the water during the wash
The drain pump removes the water at the end of the cycle
The water exits through the drain hose to the standpipe
If any link in that chain fails, water leaks. Where the water appears tells you which link has failed.
Common Causes
Failed door seal. The most common cause of leaks on front loaders.
Loose hose connection. The second most common cause.
Drain filter not tightened after cleaning.
Cracked inlet or drain hose.
Failed drain pump or pump seal.
Failed tub seal.
Failed water inlet valve.
Overfilling due to a faulty water level sensor.
Symptoms To Look For
The leak location tells you which fault pattern applies.
Leaking From The Bottom
A door seal, drain pump, or loose connection.
Leaking From The Door
A failed door seal, door alignment, or debris on the seal.
Leaking From The Back
A loose inlet hose connection or a cracked hose.
Leaking From Underneath
A tub seal, pump seal, or internal hose.
Leaking During Fill
An inlet hose or inlet valve.
Leaking During Drain
A drain hose or pump.
Leaking During Spin
A door seal or tub seal.
How to Diagnose the Fault
Step 1 — Disconnect the Power and Water
Turn off the machine at the circuit breaker. Shut off the water supply valve.
Step 2 — Locate Where the Water Is Appearing
Pull the machine out and look at the floor. Note where the water is pooling.
Step 3 — Check the Door Seal
Open the door and inspect the seal for cracks, tears, or deformation. Run your hand around it and feel for gaps.
Step 4 — Check the Drain Filter
Confirm the filter is tight. A filter that wasn’t tightened after cleaning is a common cause of leaks.
Step 5 — Check the Hose Connections
Check all inlet and drain hose connections at both ends. Tighten any that are loose.
Step 6 — Check the Hoses
Inspect the hoses for cracks, splits, or bulges. Replace any that are damaged.
Step 7 — Check the Drain Pump
Check the pump connections and housing for drips or cracks.
Step 8 — Run a Test Cycle
Run a fill, drain, or spin cycle and watch for drips. The moment the water appears tells you which part of the cycle is leaking.
Fixing Specific Leaks
Washing Machine Leaking From The Bottom
Check the door seal first, then the drain filter, then the pump and hoses.
Washing Machine Leaking From The Door
A failed door seal. Inspect the seal and replace if damaged.
Washing Machine Leaking From The Back
A loose hose connection or a cracked hose. Tighten or replace.
Washing Machine Leaking From Underneath
A tub seal or pump fault. Check the pump first, then the tub seal.
Washing Machine Leaking During Fill
An inlet hose or inlet valve. Check the connections and the valve.
Washing Machine Leaking During Drain
A drain hose or pump. Check the connections and the pump.
Washing Machine Leaking During Spin
A door seal or tub seal. Check the door seal first.
Washing Machine Leaking After Cleaning Filter
The filter wasn’t tightened properly. Tighten it.
LG Washing Machine Leaking Water
LG machines often leak from the door seal or the drain pump. Check the seal first.
Whirlpool Washing Machine Leaking Water
Whirlpool machines often leak from hose connections or the drain pump. Check the hoses first.
Samsung Washing Machine Leaking Water
Samsung machines often leak from the door seal or the drain pump. Check the seal first.
Repair Cost Guide
Door seal: $20 to $50 for the part, $50 to $100 fitted.
Drain pump: $30 to $80 for the part, $80 to $150 fitted.
Inlet hose: $10 to $30 for the part, $40 to $80 fitted.
Drain hose: $10 to $30 for the part, $40 to $80 fitted.
Tub seal: $20 to $50 for the part, $150 to $300 fitted.
Inlet valve: $20 to $60 for the part, $50 to $120 fitted.
Hose clamp: $2 to $10.
When to Repair vs Bin
Repair if:
The fault is the door seal, a hose, the pump, or a loose connection
The machine is under six years old
The repair cost is under half the cost of a comparable new machine
The machine has no other faults
Bin if:
The tub seal has failed on a machine over eight years old
The machine has multiple failed components
The repair cost exceeds half the cost of a comparable new machine
The machine has a cracked drum or tub
Safety Warning
Electrical risk. Washing machines run on mains voltage. Disconnect the power at the circuit breaker before removing any panel.
Water risk. The machine holds water. Shut off the water supply and have towels ready.
Slip risk. Water on the floor is a slip hazard. Clean it up immediately.
Water damage risk. A recurring leak can damage flooring and cabinetry. Address the fault promptly.
FAQ
Why is my washing machine leaking water?
The most common causes are a failed door seal, a loose hose connection, or a drain filter that wasn’t tightened.
Why is my washing machine leaking from the bottom?
Usually a door seal, a drain pump, or a loose connection. Check the door seal first.
Why is my washing machine leaking from the door?
A failed door seal. The seal has worn, cracked, or come loose.
Why is my washing machine leaking from the back?
A loose inlet hose connection or a cracked hose.
Why is my washing machine leaking during the spin cycle?
A door seal or tub seal that fails under the pressure of the spin.
Why is my washing machine leaking after I cleaned the filter?
The filter wasn’t tightened properly. Tighten it.
Is it worth repairing a washing machine that’s leaking water?
Usually yes, if the fault is the door seal, a hose, or the pump. If the tub seal has failed on a machine over eight years old, replacement is usually the better call.
