The tub remains empty at the start of a cycle because the solenoid valve fails to open and admit water.
Dishwasher takes much longer than normal to reach operating water level, resulting in poor wash and rinse results.
Cracked valve housing or failed internal seal causes dripping from the valve area even when the machine is idle.
Control board detects a no-fill condition and halts the cycle shortly after it begins due to a stuck-closed solenoid.
Solenoid coil energizes (audible hum) but mineral scale or a seized plunger prevents the valve from opening 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:
⚠️ Dishwasher tub is empty at the start of the wash cycle — not filling at all
⚠️ Tub fills extremely slowly, leaving dishes dry or poorly rinsed
⚠️ Water drips or leaks near the bottom-front of the dishwasher when the machine is off
⚠️ Dishwasher starts a cycle but stops shortly after — water pressure error or no-fill fault code
🛠 Diagnostic tip: Turn off the water supply, disconnect the inlet hose, and check the valve screen for mineral scale. If the screen is clear but the solenoid does not click when the machine calls for water (test with a multimeter — coil resistance should be ~200–500 Ω), replace the valve assembly.
