My Kenmore 13739k dishwasher has started to leave dirty streaks after the wash cycle has completed. It seems like the dirty water is not draining properly. Any ideas for how to possibly fix this problem?

what model number is your dishwasher?

Sounds like the wash/drain selector valve might be stuck. my Kenmore operating solenoid rusted and hung up. I cleaned and oiled it up. You can also have something that got into the valve and it won't close, or an obstruction in the drain hose or the drain pipe connector. Something is restricting the flow or the pump itself may have a bad impeller. Does it wash with vigor or has it lost a little oomph and sound different? Does it leave any debris on the dishes?

Check your drain hose to make sure no water from the sink is draining back into the dishwasher.
If it is,re-hook the drain hose up high under the sink.
Next.
Start the dishwasher without dishes or detergent.
Once the fill and was cycle begins,open the door and por in 1 quart of WHITE vinegar and resume the wash cycle to completion.

Make sure your Drain Pipe is properly fixed . any Blockage in the Drain Pipe Creates the above mentioned Problem

Have you confirmed the water has drained out, or is the water just too cold, so the heater coil is on to get water temp up. What happens if you just leave it alone? Does it continue through the cycle?

sounds like maybe one of your check valve is not working right.

wash them by hand

Try adding bicarb of soda/baking soda and vinegar in the detergent dispenser. Bicarb fizzes off hardened particles and vinegar strips off grease and aids rinsing.

Hi Dirty Dish gang.
After having 2 appliance repairmen here, I now have the latest scoop on our dishwasher problems, $200 later!
Los Angeles IS currently having hard water issues. Also, all the new cleaning gels etc. are actually a cause of our dishwasher problems.  
So, here is what we need to do:
1. Use Cascade POWDER detergent only.  Make sure is is just "plain" no "scented" or "complete"  or gel, etc. (I have tried a phosphate free powder and gel and this is a cause of our problem as well!) 2. Use Jet Dry in the dispenser (set it to a 2-3 opening) 3. Make sure water is at least 120 degrees 4. Only run dishwasher on "normal" setting.  All others just run it longer, hence causing more water stains. 5. Do not pre-wash dishes! You can knock of chunks with a "non" soapy brush, but don't rinse (the oils actually help to clean the dishes) 6.  Do not wash sponges in dishwasher.
Acid Wash: The repairman just gave my washer an Acid Wash today. It says it is an acid derived from lemon, I got mine from Carters appliance in Torrance, CA for about $19. I am to run a normal cycle with the above mentioned Cascade after this "acid cycle" is finished.
If you are still having problems:
Monthly maintenance: Glass Magic: Buy a box of Glass Magic (near the Cascade)  Use 1 Tbsb in main detergent compartment of dishwasher along with the Cascade, till washer starts working again. White Vinegar: You can run an empty dishwasher with white vinegar once a month.  Fill a bowl with 2 cups vinegar and place on bottom rack.  Then run as a normal cycle...this allows vinegar to disperse slowly.
So far it seems to be working.  Good luck.
