Question about Whirlpool Dishwashers
Your Whirlpool Quiet Partner 1 should have its model number inside along the left side. Mine is DU1010XTXT1. Your heater part is original Manufacture # W10518394. Can be purchased for about $38.00 at
or order an after market heater element part # AP5690151 for about $33.00 at
Hope this helps!

Ifixall is correct. I also learned several things with the apartment buildings I maintain.
1. the screen or pump trap must also be cleaned regularly to make sure there is no debris, food etc stuck in there.
2. The spray arms must be free of debris or obstructions.
3. Jet dry solution must be filled or has some solution in it.
4. Water must be hot
5. Scraping dishes and prewash them before putting them into dishwasher.
6 install water softner sometimes helps. (I don't know how true this is, since I am unable to do this in our buildings)
7 drain line must be picked up, or secured to prevent backwash.
8. MAKE sure that the lower rack is not obstructing the sprayer arms. Sometimes overloading dishwashers will cause dishes not being cleaned properly.
9. if all else fails, a service technician can come out to determine if the dishwasher is operating properly.

In my experience, you probably have a clog in the spray arm/arms for the top rack. Take the arm(s) out and see if the holes in them are clogged. Rice, plastic wrappers, and glass from dishes that broke in there are the most common culprits I've seen.

I have an older dishwasher also and recently my wife also complained about it not cleaning right... so me being the man I am tried in vain to clean the things... Bought new spray arms online and installed them in minutes...now the thing works like new... However I have also found that if the heating element goes bad then that also can mess things up bad... So I would buy new spray arms, and also check out the heating element to make sure it is working... Here is a tip that will help you with the online buying...
