Safety Checks You Can Do
• Check that your home's circuit breaker for the dishwasher is in the ON position; if tripped, reset it by switching OFF then back ON
• Verify the dishwasher door closes completely and latches properly with an audible click
• Review your current cycle selection on the control panel and ensure you selected a heated wash cycle
• Allow the dishwasher to cool for 15-20 minutes before attempting to restart if it recently ran
• Perform a full system reset by turning off the dedicated circuit breaker for 60 seconds, then switching it back ON
• Check that the dishwasher is receiving adequate water supply by listening for water fill sounds at the start of a cycle
• Ensure the dishwasher is not in test or maintenance mode by reviewing the control panel manual
• Verify your electrical outlet or hardwired connection is functioning by checking if other kitchen appliances operate normally
