Dishwasher not cleaning dishes on top rack

The dishwasher isn't cleaning the dishes on the top rack. There is water going to the spray arm, but it doesn't have enough pressure to make the arm rotate or to create a spray.

    I have a Kenmore dishwasher that isn't cleaning the dishes very well. Glasses have a white gritty film on them. We added a rinse agent thinking that might help but it didn't. Any suggestions?

Check the riser tube coming from the pump assembly and be sure it isn't blocked or that something else isn't obstructing the pump intake area. Make sure the upper wah arm assembly isn't excessively loose on the spindle and losing pressure because it's leaking. You may have to remove the lower rack, lower wash arm and cover to see.

If everything is clear, it could be a worn or damaged pump impeller. If the machine drains normally, it's not the motor.

Why are my top rack dishes not clean at all?


It is likely that sufficient water is not coming from the top arm. These dishwashers oscillate the water flow between top and bottoms sprays alternatively. This ensures water is pumped with adequate force. It is possible this mechanism is not working correctly. The device called check ball item 58 in this diagram actually does this function. The ball might be out of shape or not sitting properly causing incorrect wash water movement.

Hi

If the top rack of the dishwasher doesn't get clean, check your appliance to see if you can fix the problem.
First check the spray Arms to make sure the holes in the spray arms are free and clear of debris. Your dishwasher should have several spray arms, including one at the bottom of the tub, one under the top rack, and possibly a third spray arm on the top of the tub. Sometimes food and mineral deposits can block holes in the spray arms, preventing water from spraying effectively. If this occurs, warm some white vinegar and pour it into a spray bottle. Spray the holes with the vinegar and dislodge debris with a toothpick or large safety pin.

Then check to see if your dishwasher has clogged filters. Filters generally cover the drain valve area to catch debris as the water drains from the dishwasher. Many dishwashers have maintenance-free filters, but your dishwasher may have filters that need cleaning. Read your owner's manual before you perform any filter maintenance to avoid damaging your dishwasher.

Check your water temperature to make sure it's hot enough. Water that is under 120 degrees Fahrenheit may not be hot enough to clean dishes effectively. Turn your kitchen hot water tap on and wait until the water warms up completely. Fill a cup and measure the water temperature with a kitchen thermometer. If the water is less than 120 degrees Fahrenheit, turn your water heater up to 120 degrees.

Load the top rack properly. Place cups and bowls upside down in the rack and don't nest dishes because this can prevent water from reaching dishes. Don't overload the top rack. Instead, position each item so the dirty areas of the dishes will receive full contact with water spraying up from the main spray arm located beneath the top rack. Prevent items from hanging below the top rack, which could prevent the spray arm from rotating.

The dishes are not being cleaned.


clean the arms of any food debris,then if this doesn't solve the problem,replace the water channel conduit that runs up the wall of the inside of the dishwasher,after years of water pressure it will erode the fitting on the wall and rack and when the drawer rack is pushed in to wash,water will get past the o-ring on the conduit and you will lose water pressure and the arm will not function properly,replace it from the sump to the top,its not that expensive and it will assure full pressure

TOP RACK NOT CLEANING DISHES


Possible that the motor impeller has good particles in it, causing poor water pressure, which would be most evident on the top rack. You would have to remove the spray arm, then the filter, then the torx screws to get at impeller....unfortunately, that model of dishwasher isn't the greatest in the first place for washing, since it only has the one spray arm.

Dishes, glasses on the top rack dont get cleaned. The bottom rack is fine. What may be the problem?


Hi,

Probably a blocked spray arm. Remove the top spray arm and check and clean all the holes as this is where the water sprays out from to clean the dishes and glasses. When they are blocked you get poor wash results.

Will not clean dishes on the upper rack


Make sure you get water to the dishwasher. Check to see if the water shut-off valve (located under the sink) is open. If you get water to the dishwasher, but there is still no water inside during the fill cycle, the problem might be with a faulty water valve (located at the bottom of the dishwasher, behind the kick panel, on either side), in which case replace the water valve.

If there is not enough water, the dishes would not get cleaned. This could be caused by a partially closed water shut-off valve (located under the sink), or a faulty dishwasher water valve (located at the bottom of the dishwasher, behind the kick panel, on either side).

There is usually two, sometimes three spray arms in a dishwasher. Make sure there is no debris blocking the holes inside each spray arm.

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.
