Safety Checks You Can Do

Steps you can try at home safely

• Turn off the circuit breaker to the dishwasher for 60 seconds, then turn it back on to reset the appliance • Ensure the dishwasher door is fully closed and the latch is secure • Verify the water supply valve under the sink is turned on completely • Inspect the drain hose for visible kinks, bends, or damage and straighten if necessary • Check where the drain hose connects to the sink drain or garbage disposal and ensure it's firmly connected • Remove and clean the dishwasher's filter basket (usually located at the bottom of the tub) of any visible food debris • If you have a garbage disposal, run it to clear any clogs that might block the dishwasher drainage • Check that you're using the correct dishwasher detergent and proper amount for your water hardness • Review your dishwasher's control panel settings and cycle selection to ensure proper settings are selected • Look under the sink to ensure the drain hose isn't pinched between the cabinet wall and pipes • Run a cleaning cycle with dishwasher cleaning solution to help clear mineral buildup from internal components
