The Service Call: Uncontrolled Water Inflow
An Oakland Park homeowner contacted iFixExpress after discovering their LG washing machine was overflowing with water even when switched off. To prevent extensive water damage to their laundry room floor, the customer had wisely shut off the main water supply valves behind the unit before calling for emergency repair.
Diagnostic Procedure & Testing
When a washing machine continues to fill while powered off or in pause mode, the culprit is almost always mechanical rather than a control board failure. In modern electronic washers, the water inlet valves rely on electromagnetic solenoids and internal diaphragms to seal water pressure.
1
Safety Isolation: Disconnected the appliance from AC power and pulled the unit forward to access the rear connection panel.
2
Bench Testing the Coils: Removed the wire harnesses from the multi-valve block. Using an external 12VDC test battery, direct voltage was applied systematically across each solenoid coil to monitor operation.
3
Pinpointing the Defect: While three of the valves energized and closed crisply upon removing power, the cold rinse valve opened under current but failed to reseat mechanically once voltage dropped, letting pressurized water bypass the diaphragm.
The Repair Solution
Because the valve seats are sealed factory units and internal plastic diaphragms degrade over time from hard water or sediment, replacing single solenoids is not recommended. We removed the entire defective manifold and installed a genuine OEM LG water inlet valve assembly.
After securing all internal feeder tubes, tight hose clamps, and wiring clips, the home supply shutoffs were restored. The washer was run through an express fill and drain cycle to verify fast shutoff response and confirm leak-free seals.

Preventative Advice for Homeowners
If your washing machine continues filling with water when the power button is off, immediately close both the hot and cold wall valves. This symptom indicates a mechanical seal failure inside the valve assembly that no cycle reset will fix.
Frequently Asked Questions
When a washer fills without power, the internal diaphragm inside the water inlet valve has physically jammed open or degraded. Because it requires mechanical pressure to seal against house water pressure, a worn valve will constantly leak water into the drum.
Modern LG washers utilize a molded multi-valve assembly. Replacing the entire block ensures balanced water pressure, new internal seals for both hot and cold lines, and long-term reliability against future leaks.
Locate the water shutoff valves behind or above the washer and turn them clockwise until fully closed. This prevents the tub from overflowing onto your floors while you wait for a technician.
A standard water inlet valve replacement typically takes between 30 and 60 minutes, including testing the electrical solenoids, installing the new assembly, and testing full water cycles.
