How to fix it

  1. Open the under-sink water shutoff valve fully.
  2. Verify water flow at the kitchen sink.
  3. Pull the dishwasher out far enough to check the fill line for kinks; reroute as needed.
  4. Close the door and press Start — the dishwasher will resume the cycle.
  5. If H2O returns with the supply confirmed open, escalate to F6E1 troubleshooting (inlet valve / strainer).
