Dishes are not clean at the end of wash - Kenmore 16372 / 16374 / 16379 Built-in Dishwasher

Check your upper wash arm.... check the holes, especially the ones at the end of the arm. Are they possibly clogged with debris or hard water? This is the usual cause of dishes on the top rack not getting clean. The holes at the end of the wash arm are angled to eject the water at an angle to use the reaction to push the wash arm around. If those holes are clogged, then the arm won't rotate, and only those few dishes or glasses right under the arm will get clean, and the remaining 80% of the dishes on the upper rack won't get clean!

Your screens are plugged with food residue in the bottom of the unit. clean it out. You can use 1 gallon of white vinegar for your wash after you clean the screens. Start your washer to fill with water but after the water starts, open your door and pore all of the gallon in the unit. Let it now run for 4 minutes and stop it by opening the door. Leave the door slightly open for 1 hour. close the door and let the cycle continue for 4 more minutes. open the door and repeat it a couple of more times. Let it sit all night with the vinegar in it and in the morning - close the door and let the cycle continue to the end. This should help soften and clean out the food particles in the unit. You can repeat the process and get a better cleaning then too. All the scale should be off your dishes now.

You may have a bad detergent dispenser.

Remove the filter from the lower front section of the wash tub and clean it out.
Then start a wash cycle with no dishes and no soap.
Once the water fills and starts washing,open the door and pour 1 quart of white vinegar in the wash tub.
Close the door to resume the wash cycle.
Let the machine run a complete cycle to the end to help clean out the water ports.

Sounds like your drain is clogged. The drain should be located just below the blades inside the dish washer when you pull the lower rack out. If you can clean it from the top end, that could be a simply fix. Otherwise you'll need to pull the dish washer out and clean the drain from the bottom.

Also, check your Blower Fan to make sure it is still running.

Yes! you are already having the answer. check your water inlet flow. Clean the strainer at the machine water hose connecting end.

Check the drain filter also. Refer user guide for instructions on cleaning.

I switched it off at the wall and left it for a minute and set the dial to Stop and then set it again from the beginning and so far it has been fine. Thanks, DCD

Clean the filter.  It is at the bottom below the wash arm.  Remove the wash arm by lifting it off.  The filter is a round ring the can be lifter out and cleaned.

Hi there!

You've done the basics, so we'll treat it as a fault due to wear.

When running, do you hear the spray arms rotating - about twice a second?

If the water is actually reaching the dishes, bur the arms are not rotating, you may need replacement spray arms.

If the water is not even reaching the dishes with any force, The circulation pump may be faulty and needs replacement.

Hope this helps you.
