Here is what I found from the manufacturer.....so I guess the only thing to check is the duct and the fan...Can you tell me how to check those two items? I used to live in this house and it never bothered me, but the last two renters have complained a lot. From manufacturer: "Because the unit does not rely on a heating element for this process, it relies on the heat that is retained by the dishes during the wash and rinse cycle to turn the moisture in the tub into steam (humidity). Warm, moist air in the dishwasher is then pulled into a condensing duct in the door by a fan. The duct allows the hot, moist air to cool, which causes the steam to condense. This process is aided by room temperature air which is also drawn in to the duct and cools the air."Rinse Aid is required to enhance dry performance of the unit. If no rinse aid is used, water will remain on the dishes and in the tub.
okay. so basically what the manufacturer is saying in the statement above that there is no heat or drying cycle for this particular dishwasher. That it uses the heat and steam from the hot dishes during its wash cycles to heat the moisture left over from wash cycle and will eventually evaporate. And the fan and duct inside the door, which usually doesnt have to be checked or cleaned or even maintained in any way, will aid in the drying time for the dishwasher.
on your model dishwasher there is a small duct or air channel inside the door that will vent out any steam and let in clean dry air from outside the door.
This duct doesnt ever need to be cleaned or checked. In my over 13 years of doing appliance repair i have never seen this duct jammed or blocked in any way.
The only way that the air can be obstructed is if you have a piece of decorative molding directly under the door blocking the air flow. And even on the integrated models that use a cabinet face to match your other cabinetry, the duct and air flow from it never gets obstructed to the point where it will prolong the drying time.
I would suggest using the rinse aid if you are not already, and if you are, make sure the rinse aid dispenser is set correctly and refill it. Then run about three empty wash cycles with no dishes. and just use white vinegar in the detergent cup of the dispnser. and use about 4 ounces of the vinegar.
And set the dishwasher on the longest, hottest wash cycle, usually the sanitary or pots and pans cycle will do, and let it wash and complete its cycle. Then run this cycle two more times with same amount of vinegar each time. This will clean out your dishwasher and help in drying time. It will even help in washing the dishes too.
After the three cycles run two empty cycles again on hottest wash cycle possible but this time use no vinegar just regular dish detergent.
after this you can use the dishwasher as normal again making sure you are using the rinse aid and everything should be fine for you. If the dishes are still nto coming out dry enough for you then i suggest again, after the wash cycle and draining of the water in the cycle, opening the door and allow the dishes to air dry.
