Safety Checks You Can Do

12
  1. 1
    • Turn off the dishwasher at the main control panel and verify the circuit breaker in your home's electrical panel is in the ON position; switch it OFF then back ON after 10 seconds
  2. 2
    • Power cycle the appliance by turning off the circuit breaker completely for 60 seconds, then turn it back ON to reset the control board
  3. 3
    • Verify the water supply shut-off valve under your sink (behind the dishwasher) is fully turned ON by rotating the handle counterclockwise
  4. 4
    • Check that the inlet hose connected to the back of the dishwasher is not kinked, twisted, or pinched; straighten any bends carefully
  5. 5
    • Inspect the inlet hose for visible cracks, holes, or water leaks along its entire length
  6. 6
    • Remove and rinse the inlet hose screen filter (located where the hose connects to the dishwasher) under running tap water to remove sediment and mineral buildup

    • Ensure the dishwasher door is closing completely and latching firmly with an audible click
  8. 8
    • Check that the door latch is not obstructed by debris or food particles
  9. 9
    • Run your kitchen sink faucet to confirm adequate water pressure is available (water should flow steadily)
  10. 10
    • Inspect the water supply line connection points under the sink to ensure they are hand-tight and not leaking
