Start by unscrewing the air, hose clamp, and gap cover from the sink and removing any food or debris that may have accumulated inside prevent water from coming in. Check the air gap hose for any visible blockages first, and remove any you find.
Finally, reassemble the dishwasher from leaking air gap, and you’re good to go! With these simple steps, you can ensure your dishwasher’s air gap functions properly and prevent any potential leaks.

If it doesn’t, it’s likely that the valve is faulty.
You’ll need to replace the water inlet valve to fix this issue. However, it’s a complicated repair that involves working with the electronics of your dishwasher. Therefore, leaving this task to a qualified dishwasher repair technician is best.
