Washing Machine Fills With Water When Off? Shut Off the Supply Before It Floods
If water enters a washing machine while it is switched off, unplugged, or between cycles, treat it as a flood-risk problem rather than a setting issue. A worn water-inlet valve can fail to close fully and allow a slow stream into the tub. Less often, a cross-connection or supply problem can push water through the machine. Do not keep running cycles to empty the tub, leave the home with the supply valves open, pull the washer out while it is full, or open cabinet panels around wet wiring. Shut off both washer supply valves if they turn normally, then arrange service before using the appliance again. If water has reached an outlet, power cord, extension cord, or standing water near electricity, stay out of the area and get qualified help.

Common Symptoms
- Water slowly appears in the washer tub while the machine is off or unplugged
- The tub refills after being emptied, often with clear cold, hot, or mixed water
- Water continues entering when no wash cycle is selected
- The laundry floor is wet, the drain hose is overflowing, or the machine has begun leaking
- The supply valves are difficult to turn, corroded, or show visible leakage
Most Likely Causes
- 1
Leaking water-inlet valve
The electrically controlled inlet valve should close when the washer is off. Mineral buildup, debris, a worn seal, or a damaged valve can let water seep through even without power.
- 2
Water-supply pressure or cross-connection issue
In some plumbing setups, water can move through a mixing fault or cross-connection. A technician may need to separate appliance and plumbing causes rather than replacing parts blindly.
- 3
Drain or overflow problem happening at the same time
A tub that fills is distinct from a drain hose backing up, but both can cause floor damage. If water appears around the standpipe or drain, the drainage system also needs attention.
- 4
Damaged supply hoses or shutoff valves
A failing hose or valve may leak externally while the machine has an internal inlet-valve problem. Do not force a stiff, corroded shutoff valve.

Quick DIY Checks
WATER AND ELECTRICAL CAUTION: Do not touch the washer, outlet, power cord, or breaker if water is on the floor near electricity. Keep people and pets away from the area and call a qualified professional if water cannot be safely separated from power.
CALL AN APPLIANCE TECHNICIAN OR PLUMBER if the supply valves will not close, a valve or hose leaks, the washer keeps filling after the supply is shut off, water has damaged flooring or reached electrical equipment, or you need to remove panels, replace an inlet valve, or alter plumbing.
- 1Stop water flow first. Turn both washer supply valves clockwise only if they move normally and the area is dry. If a valve is seized, leaking, or inaccessible, do not force it; use the home’s accessible main shutoff only if you know it is safe to operate and call a plumber.
- 2Unplug the washer only if the plug, outlet, floor, and your hands are completely dry. Do not touch a cord or outlet near standing water.
- 3Mark the water level with removable tape and check whether it rises after both supply valves are closed. Photograph the valves, hoses, and tub level for the technician. Do not remove hoses or panels while water is present.

Repair vs Replace
An inlet valve is commonly repairable and is usually far less expensive than replacing an otherwise reliable washer. Replacement becomes more reasonable when flooding, corrosion, multiple control failures, or drum and drive problems also affect an older machine.
Est. Repair Cost
About $150–$400+ for diagnosis and inlet-valve replacement; plumbing repairs vary
Est. Replacement Cost
$600–$1,400+ for a comparable new washer

Frequently Asked Questions
- Why does the washer fill when it is unplugged?
- The water-inlet valve can leak mechanically even with no power. Unplugging alone does not stop household water pressure, so close the supply valves.
- Can I leave the supply valves open until the repair appointment?
- No. Keep both washer supply valves closed when the appliance is unattended until the cause is corrected.
- Is a little water in the tub normal?
- A small amount left after a cycle can be normal, but a level that increases while the washer is off indicates a problem that should be addressed.
