Dishwasher does not clean properly

The top arm in my dishwasher does not seem to be spinning during wash. Items on the bottom rack are clean, but not the top. I have removed the spray arm and cleaned it, but no help. The tube feeding the arm is not clogged either, as it also supplies the "rain" at the top of the tub, which is working. Help! I have by-passed the lach to keep the dishwasher running while door is open. There is water coming out the bottom spray bar (but not enough for it to spin) there is no water coming out the top spray bar. Can you help!

SOURCE: dishwasher does not clean properly

sewnice, you might have to dig a little deeper to correct the problem. As long as you can spin the spray arm with your hand and it's not split it should be ok. Your chopper screen might be plugged. You will have to remove the lower spray arm and filter cover. These are torq screws. The accumulator assy. turns to the right to unlock and will lift off. It will take some pressue to snap it off the rear fill tube. Now you will be looking down at the cover that protects the chopper and screen. There is one torq screw holding it down. Remove the screw and lift it off. See if the screen is clogged. If it is, it will prevent the pump from sending water to the upper spray arm in force. Catriver..post back

Aquarius model dwf31. Why doesn't it clean items in top rack?


If you look at the bottom arm you will notice an extension nozzle that comes up out of the center. If you block that from going up during the wash cycle with dishes then the water will not reach the top. This is what makes the top arm spin.

  1. Check the water temperature. Should be 125 to 140 F.
  2. Check pump re-circulation., Listen, see if it sounds like it is spraying the water around with enough pressure.
  3. Check water level when the fill cycle has completed. Should be just under the heating element. If not, possibly need to replace the water inlet valve.
  4. Check the spray arm and pump cover for splits or leaks.
  5. Check to make sure dishwasher is draining after each cycle. There should only be a little water in the bottom of the tub.
  6. Make sure the dishes are loaded properly, or dishwasher is not overloaded.
  7. Possibly try a different detergent. Some liquid-gels will bubble and a pump cannot pump bubbles.
Scrape away large pieces of food, bones, pits, toothpicks, etc. Burned on food should be loosened before loading. Empty liquids from glasses and cups. Foods such as mustard, mayonnaise, vinegar, lemon juice and tomato products may cause discoloration of stainless steel and plastics if allowed to sit for a long period of time. Unless the dishwasher is to be operated at once, it is best to rinse off these food soils. Load racks so that large items do not prevent the detergent dispenser from opening. If the dishwasher drains into a food disposer, be sure disposer is completely empty before starting the dishwasher.

Why are the items on bottom rack not being cleaned properly


If is clean dishes in the upper basket, I conclude that the pump produces enough pressure what means that the lower spray arm for some reason does not rotate and because that washing result is bad. Before washing I would check the lower spray arm rotates freely and after that open the door during washing and check if the lower spray arm rotates. Sometimes, the holes in the spray arm clog and disable turning which leads to poor washing results in the lower basket.

Dishwasher leaves dirt on top rack


Still worth checking for hot water though, stop machine when you know its at a stage where the water is suppose to be hot. Also when the machine is loaded that the top arms are able to spin freely without hitting anything. Also make sure top arm holes have not got any old foo stuck in as this will stop them from spinning properly. Open door during wash and close door then re open to see how far around it has gone. Not as powerful as the bottom arm but shouldnt be that far of.

Bottom rack cleans fine, top rack doesn't clean at all - can I take apart the top spray arm?


yes, the spray arm can be removed and cleaned out.

Also, clean the 3rd (very top spray area) located attached to the top of the dishwasher. You want to make sure this small (1 inch size) piece can spin freely, so water can rinse the upper rack items.

The dish washer is taking ages to wash and it not clean ing dishes well


ok so If your dishwasher has worked fine in the past but, suddenly, your dishes aren't clean after the dishwasher completes all cycles:
1) Check your water heater's temperature dial to be sure it hasn't been changed recently.
2) Be sure dishes haven't prevented the detergent dispenser from opening properly during the wash cycles or kept the spray arms from turning, the lower arm from rising, or the spray from reaching the upper rack's dishes.
3) During the wash cycle, listen to the spray arm spinning inside. If it seems to be spinning poorly, clean out the spray holes in the spray arm(s) with a stiff piece of wire; wait for the machine to cool, and then remove the spray arm(s) by unscrewing the hub cap and lifting the arm(s) off

Upper rack is not cleaning. Greasy dishes on top seem that dishes are not being washed. Seems the upper water turning dispenser is not working, Bottom rack seems ok. I guess I only have half a dish washer...


Check the upper arm for free spinning, then remove the arm and check that the seam between the upper and lower halves has not split somewhere. Also check all the small holes for debris plugging. Run the machine in wash cycle for a little while with the upper arm off--that should flush out anything blocking the pipe up to the arm. If still nothing from the upper arm, tear down the lower arm assembly down to the deck while noting position of all parts removed. Clean the big screen at the bottom in white vinegar and hot water. Inspect the holes in the bottom for anything blocking them.

My dishwasher is not washing dishes on the top rack...


HI,

The top rack is not cleaning because of low water pressure from the wash motor to the upper spray arm.
Assuming the top spray arms are clear of debris, remove the lower spray arm to access the wash motor. Remove the 4 torx screws and the filter (accumulator assembly). Remove the torx screw and the inlet protector that covers the chopper assembly. Make sure the chopper is not broken (broken chopper will fill with debris and block water flow). While holding the chopper blade, reach inside the "D" shaped opening on top of the motor and spin the wheel/motor by hand in each direction to make sure either the chopper gear or the motor gear that drives the chopper is not broken. Replace the chopper if necessary . If the motor gear is broken, replace the sump and motor assembly . Remove any debris from the sump area in the process.
You don't have to shut the power off to the dishwasher because the door will be open, but if you feel more comfortable, do so.


thanks,

Only washing top rack


After observing the water just gushing out when the spray arm was removed, we determined there was still a bunch more calcification/soap in the ends of the spray arm. (We have very hard water in our area). Unfortunately, you cannot open up the spray arms to clean them out, so it took about 30 minutes of pounding and manipulating to get all the gunk out. Now my dishes are clean again. Hallelujeh! And the water cleaning the dishes is cleaner, as well.
