I have a new GE Dishwasher model PDW9900NWW that has a concealed vent with
fan assist drying.
It uses a fan that pulls the moisture out of the tub and down a tube that
exhausts through a plastic tube that runs half way across the underneath of
the door from left to right. As it blows the warm moist air across the
underneath middle to right of the door it appears to be causing moisture on
the metal right hinge, which depending on the cycle used may build up enough
moisture to drip to the floor.
The GE service tech mentioned that the solution is to reseal the fan
enclosure inside the door as they left a spot on the mold that does not
allow the gasket to seal. This causes the fan to suck in extra moisture.
I am wondering if anyone else has a similar model and can help with this. It
seems to me that as long as warm moist air blows towards that hinge,
moisture is going to form.
Thanks for your time and assistance,
I have a new PDW 9280. Not sure if it's similiar, but I keep the
"heated" option on all the time for the drying cycle. Does your
problem happen with or without the heated option on?
My fan stays on for a good 3-4 hours after the cycle finishes, but
according to tha manual, that's normal operation..
Have you noticed the tube I am mentioning? If so, I would be interested in
knowing if you look under the door bottom and notice a buildup of moiture
especially along the right bottom of it and on the right hinge.
The fan is suppose to run, and that is what appears to be taking the
moisture out of the tub and exhausting it at the bottom of the underneath
portion of the door.
Ben, I looked at mine. I have the same setup. I never really noticed
moisture on the floor, but I always use the heat dry setting. Next
time I do a load, I'll let it air dry to see if I notice anything.
sure, if you check out the bottom or the right hinge you will see moisture
on any setting. Please let me know.
BTW, does it have the Smart Dispense? If so, I'd be curious to know how many
loads you get from a fill up.
I did a load last night with normal dry, I did not see any moisture on
You mentioned that you use the antibacterial wash, which is when you
notice the moisture. Doesn't the water get heated up quite a bit in
that wash mode? When the fan takes out the high humid air from the
washer and expels it into a cooler environment, maybe it's condensing?

The next time you run any load would you mind looking/feeling underneath to
see if yours is condensing on the right metal hinge? Mine always condenses
there, and on the hotter loads the condensation drips from there to the
Again, I appreciate your assistance. Thank you.
I did try to feel for moisture at the right hinge last night while it
was drying, I did not feel anything, but I was on normal dry mode. Its
amazing considering the tube ends at the middle of the door, yet the
moisture travels to the right side of the unit.
Perhaps the moisture collects at the middle of the door, and if the
unit is not perfectly level, it rolls to the right side. Just a
For the heck of it, the next time I do a load I'll run on
antibacterial. I have not done that mode yet, so this will be a first.
Ben, I did a load on antibacterial, and while the air was super hot
coming out of the tube, I did not see any moisture on the hinge.
Although I can see why there is a real potential for moisture to form
on that hinge.
Just out of curiousity, why do you use antibacterial mode? It seemed
like the wash cycle took longer than the normal cycle. Antibacterial
seems like overkill, unless you really need everything sterile.
I always have atleast moisture on the right hinge/door area. I can put my
hand around the hinge and bottom door edge and always get moisture when the
fan is running right after a load. I will have the Tech seal the area around
the fan as he suggested. I'll let you know if that corrects it.
Again, thank you very much.
