If your dishwasher won't start but the lights are on, check the door latch to ensure it’s fully closed. Inspect the control lock to make sure it isn't engaged. Verify that the delay start option isn't activated. Reset the dishwasher by unplugging it for a few minutes and then plugging it back in. If these steps don’t work, the issue might be with the motor start relay or a faulty control panel, which may require professional assistance.
