Tub fails to fill with water at cycle start; machine senses and then drains without washing.
Control panel displays H2O Supply fault mid-cycle; washer drains and stops before agitation begins.
Water drips or trickles continuously into the wash basket when the machine is off, indicating a solenoid not seating properly.
Washer fills with water very slowly, or only one temperature (hot or cold) enters regardless of the selected cycle setting.
Bleach or fabric softener compartment fails to flush into the tub during the appropriate cycle stage due to a failed solenoid port.
Anti-flood circuit triggers the drain pump to run when the tub fills unexpectedly, caused by a valve solenoid failing to close fully.




💡 Pro Tip: How to Know Your Water Inlet Valve Has Failed
Your part is likely the culprit if you notice any of the following:
⚠️ Washer tub does not fill with water at the start of a cycle
⚠️ Water fills extremely slowly or only cold/hot water enters regardless of setting
⚠️ Water leaks around the back of the machine or drips into the tub when the washer is off
⚠️ H2O Supply error code appears on the display panel and the cycle fails mid-fill
Diagnostic tip: Use a multimeter set to ohms and probe each solenoid terminal pair on the valve. A healthy solenoid reads 500–1500 Ω. An open circuit (OL) or reading outside this range confirms the valve has failed and must be replaced — do not attempt to clean or rebuild the valve assembly.
