Hello countrygirl, the WDT750SAHZ does not feature any kind of external air vent, rather as the unit cools the moisture forms drops of water on the stainless steel tub and with Rinse Aid, drains out. You may just need to increase the amount of Rinse Aid dispensed. Your Use & Care Guide will show you how to adjust this setting please see page 7. Also it is very critical each cycle starts with water at 120deg. We suggest turning one the water faucet nearest the Dishwasher to full hot and wait until that water is at the max temperature before starting a cycle. We value your time and would be happy to speak with yo on your appliance if you have any further concerns. Please reach out to us directly at 1-800-253-1301, via Facebook https://www.facebook.com/whirlpoolusa or Twitter @WhirlpoolCare. We’re looking forward to hearing from you.
