  1. 1
    • Check the circuit breaker panel and ensure the breaker serving the dishwasher is in the ON position; flip it OFF then back ON if tripped

  4. 4
    • Disconnect the inlet hose at the wall connection and briefly run water into a bucket to ensure adequate water pressure
  5. 5
    • Check if the inlet hose has ice buildup (in cold climates) and allow it to thaw naturally
  6. 6
    • Remove and inspect the inlet hose filter screen for debris or sediment; rinse under clean running water if clogged
