The inlet valve solenoid has failed open or the valve screen is clogged with mineral deposits, preventing water from entering the tub at the start of the wash cycle.
A partially blocked or worn valve restricts water flow, causing the dishwasher to underfill and deliver poor cleaning results due to insufficient water pressure at the spray arms.
The valve body or internal diaphragm has cracked or degraded, causing water to drip or stream from the valve area under the dishwasher tub during or between cycles.
A buzzing, humming, or vibrating noise heard at the start of the fill cycle indicates the solenoid coil is struggling to open the valve, signaling imminent valve failure.





💡 Pro Tip: How to Diagnose a Failing Water Inlet Valve
Your part is likely the culprit if you notice any of the following:
⚠️ Dishwasher does not fill with water at the start of the wash cycle
⚠️ Dishwasher fills very slowly or only partially during the wash cycle
⚠️ Visible water leak coming from the valve area under the dishwasher
⚠️ Unusual humming or buzzing noise during the fill phase of the cycle
Tech Tip: Before replacing, use a multimeter to test solenoid continuity on both terminals. A reading of OL (open circuit) confirms a failed solenoid coil. Also check the water supply line for kinks and the inlet screen for mineral deposits — hard water scale is the #1 cause of premature valve failure on Bosch dishwashers.
