Dishes not dry enough & leak of water at sink vent device

HEATED DRY.Turns the drying heater on for fast drying.
ENERGY SAVER (no heat boost). Turns the drying heater off to save energy. Dishes will dry naturally over a longer period such as overnight. lf you need your dishes sooner, open the dishwasher door after the cycle is complete to reduce the natural drying time. Use of this option reduces the electrical energy used by this model approximately 7%. A rinse agent makes water flow off dishes quicker than usual. This lessens water spotting and makes drying faster, too.
Make sure inlet water temperature is correct.(SeePage6.)
Unload the bottom rack first.Water from dishes in the top rack may be spilling in to the
bottom rack.
Check for improper loading.Dishes shouldn’t nest together. Avoid overloading. Check the rinse agent dispenser to see that it’s not empty.

Inlet temperature....Good Dish washing starts with hot water, To get dishes clean and dry,you will need hot water.To help you get
water of the proper temperature, your dish washer automatically heats the water in the wash cycle. For good washing and drying , the entering water must be at least 120°E To prevent dish damage,
inlet water should not exceed 150”F. How to test water temperature: Check the water temperature inside your dishwasher with a candy or meat thermometer. Let the dishwasher run through
one fill and pump out cycle, then let the dishwasher fill with water
the second time. When you hear the water stop filling, unlatch the door and slowly open it. Measure the temperature of the water in the bottom of the tub this way: Remove the silverware basket and
place a candy or meat thermometer in the water towards the middle of the tub. If the temperature is less than 120”F,you will not get good washing results. Higher water temperature is needed to dissolve grease and activate powder detergents. If the unit is a long way from the DW you may need to let the water run in the sink until hot before starting the DW....or if is a cold day and water has not been used in a while the pipes could be cold....also if you have just used the hot water ( washer, shower...etc) give it time to recover first before using DW....All of the above mentioned material is straight out of the Users guide...but you may have an element that is going out also...so check the temp of your water and open it during the drying cycle to see if it is hot or at least warm inside...if not your element may need to be replaced...

I hope this helps...have a great day & good luck...please rate my effort.... the Fang.
