Safety Checks You Can Do

Steps you can try at home safely

• Turn off power to the dishwasher at the circuit breaker for 60 seconds, then turn back on to reset the control board • Verify the dishwasher door is fully closed and latched securely • Check that the main water supply valve under the sink is fully open (turn counterclockwise) • Inspect the water inlet hose for kinks, twists, or damage behind and underneath the dishwasher • Verify your household water pressure is adequate by checking another faucet for normal water flow • Remove and clean the dishwasher filter basket of any debris or food particles • Confirm you are using the correct type of dishwasher detergent (not hand soap) • Check that the control panel settings are correct and the cycle selection is appropriate • Ensure the water supply valve shutoff valve is in the fully open position • Inspect accessible inlet hose connections at both the dishwasher and water valve for leaks or loose fittings
