My whirlpool dishwasher is not cleaning dishes all the way. some are still dirty after a full cycle

hit the cancel drain cycle. Often times the dishwasher drain hose is not installed properly. It must be routed up as high as the dishwasher as soon as it comes out of the unit. May be also that there was a little regular soap or something that made it sudds up. vegetable oil poured into the dw tub will remove the sudds. After running vegetable oil for about 5 minutes, pour 2 cups of vinegar in to the tub and run it on the hottest longest cycle with no dishes in it. This will clean the residue out and what ever "gunk" may be in the internal parts. Use Only powder detergent. No gel and No tabs. These 2 cause a build-up over a period of time of use and reduce the performance of your machine.

The problem is hard water. Go to www.dishwasherfilter.com and get their new product. It filters the water and takes out the hard minerals that cause spots and clog dishwashers. It is very affordable and has a money back guarantee.

Put dirty stuff in will eventually keep a tech like me very busy. We love to come and charge you alot for cleaning your dishwasher. Remember the Maytag commercials where they put a cake in it? Still got the dishes clean but before long it will cost you big time. Just run everything under the tap. Pot and pans should be lightly washed also. Watch how you place the dishes. Most dishwashers spray up from the bottom. Block it, and the spray will not reach the top.

If you have hard water, it is likely that the sprayer in the bottom of the dishwasher has become clogged with hard water deposits. This may be the case, even with soft water.

On most models, the sprayer looks like a propellor, and can be removed by carefully unscrewing the fastener at the top and carefully removing the sprayer. If you have a digital camera, I recommend taking pictures at each disassembly step, so you know how to put things back together (in the reverse order that they were removed). It should not be too difficult to remove it, but you may have to gently work with the fastener at the top to get it to budge.

You will need to clean all the spray holes and ensure that none are clogged. I used an ice pick and toothpicks to clean out the holes recently on my dishwasher. (We have hard water).

You may need to soak the sprayer in vinegar overnight if you're not able to completely clean out all the holes.

Good luck!

I had a similar problem with my last two dishwashers, with food still left on the dishes at the end of the cycle. What a nightmare. The most recent dishwasher is new, now the problem is solved. Here's what the manufacturer told me. Pour white vinegar (approximately 2 cups) into the dishwasher and run through the cycle. Buy some Cascade Complete and only use this type of soap for the dishwasher. Make sure you run a cup or two of the white vinegar through the dishwasher cycle once a week. My dishes are now clean and clear!!
