Dishwasher starts a cycle but no water enters the tub — dishes remain dirty. The solenoid coil or valve seat has failed, blocking water flow entirely.
Water drips from the valve body or bottom pan area. A cracked housing or stuck-open solenoid causes continuous seeping, triggering Bosch flood-protection drain mode.
Dishwasher keeps filling with water after the cycle ends or overflows onto the kitchen floor. The solenoid is stuck open and cannot shut off water flow.
Dishes come out dirty, especially on the top rack, because insufficient water enters the tub due to a partially clogged or weakened inlet valve.
A humming or buzzing sound occurs during the fill cycle but water does not enter. Mineral deposits have blocked the valve screen or the coil is energized but the plunger is stuck.
💡 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 will not fill with water at the start of a cycle — dishes come out dirty or unwashed
⚠️ Water leaking from the bottom or front of the dishwasher — valve body cracked or not sealing
⚠️ Dishwasher overfills or keeps filling after the cycle ends — solenoid stuck open
⚠️ Dishwasher enters continuous drain mode (Bosch flood protection triggered by water in drip pan)
🔬 Diagnostic tip: Remove the valve and test the solenoid coil with a multimeter. A healthy coil should read 900–1,100 Ω resistance. An open circuit or zero reading means the valve has failed electrically and must be replaced — water inlet valves are not repairable.
