• Turn off the dishwasher and allow any standing water to cool for 15-20 minutes before attempting inspection• Verify the home circuit breaker controlling the dishwasher is not tripped; reset if necessary• Unplug the dishwasher from the electrical outlet or turn off its dedicated breaker for 60 seconds, then restore power to perform a reset• Check that the water supply shut-off valve under the sink (if accessible) is fully open• Inspect the drain hose connection at the sink or garbage disposal for kinks, twists, or pinches and straighten as needed• Verify the drain hose is not positioned higher than the dishwasher drain outlet, which can trap water• If a garbage disposal is connected, run it to ensure it is not clogged or jammed• Open the dishwasher door fully and ensure it closes completely with a solid clicking sound, indicating proper latch engagement• Remove the bottom rack and inspect the drain filter area for visible food particles, debris, or mineral buildup; rinse the filter under running water• Check the spray arm holes (located on the spray arms) for blockages caused by food or mineral deposits; clear with a toothpick or small wire if needed• Examine the drain hose where it connects to the sink or garbage disposal for cracks or damage• Run a test cycle with an empty dishwasher to see if the error reoccurs after your checks• Confirm you are using USA-appropriate dishwasher detergent in the correct quantity for your water hardness level; excess detergent can create foam that interferes with drainage
