the only way you can tell if the upper rack is not getting enough water is to turn a glass right side up in each corner. then run for 2 minutes and see if there is water in each cup.
if you still dont get water, then you have checked the pump, the only thing left is that you are not getting enough water into the unit.
start the d/w at a normal cycle, let it fill and go into the wash cycle, takes about 3 minutes, then check to see if the water level is just below the heating element. if so then it has to be the wash pump being plugged.
if not enough water then you should change the water inlet valve. some times they do get plugged but also make sure you are getting full water pressure to the unit as that could cause not enough water into unit. the faucet under sink could be at fault i have seen valve work but not let enough water in, so dont be surprised if you need a new valve.

SOURCE: 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,

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.

SOURCE: My whisper quiet dishwasher is not cleaning the top rack dishes

I'm having the same problem. Did some testing and found that the sprayer on the top rack is not even moving and hence not getting any water. Not sure what to do.

Dishwasher leaves upper rack dishes dirty. It's Whirlpool Quiet Partner II


Your water pressure is not high enough in the dishwasher to wash the dishes on the top rack. The most common reason is that the pump in your dishwasher cannot pump fast enough to keep the water pressure up. That is because the shaft that drives the pump impeller also drives the macerator cutter that grinds up bits of food fine enough for it to pass through the screen and out to the drain. Over time, small bits of bone, broken glass, eggshell, and other items that are too strong to be cut up by the cutter end up sitting in the area where it has to spin, and they prevent it from spinning fast enough to pump enough water to the top rack with any pressure. It is simple enough to repair. You need to take out the racks, remove the bottom arm and clean out the little macerator. Once that is done, it should work great again.

My dishwasher wont clean the dishes. The bottom rack gets kinda clean and the dishes on the top rack come out dirty and covered in film.


Check whether the top rack spray arm main hose sits firmly into the
machine. If there is a leak in this area water pressure may not develop.
Also check the water pump in the machine!

DISHES ON TOP RACK ARE NOT GETTING CLEAN TOP SPINNER NOT SPINNING POSSIBLY NOT ENOUGH WATER PRESSURE?


It would help if you provided the make and model of the dishwasher.
Most likely cause of not getting enough water pressure to top rack is the water diverter may be faulty.

Depending on the model - it is a small ball floating in a vertical channel which alternately opens and closes the bottom and top water inlets to the spray arms. Check part at Repair Clinic after selecting make & model of your dishwasher.

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.

Bosch SHU 8805 upper arm is getting no water.


replace the upper water arm conduit and wash arm hub as they leak under years of pressure and the o-rings leak water and then it can't hold pressure and supply the upper arm with full pressure water,also replace the center arm conduit if it has one as this will wear out too

DISHES ARE NOT COMING CLEAN BYPASSED THE DOOR LATCH TO WATCH CYCLES,LOOKS LIKE THERE IS NOT ENOUGH WATER PRESSURE TO ACTIVATE THE WATER TOWER AND ROTATING ARM?WATER PUMPS OUT BUT NOT ENOUGH TO MAKE THINGS...


I had the same problem and fixed it by disassembling the lower spray arm and return filter, and cleaning all the junk out.
Most dishwashers have 'risers' that bring the water up to the top sprayer or arm located under the top rack. If the recirculating pump is plugged even a little there won't be enough volume or pressure to get the water up there.
Test this by putting a dry muffin pan in the top rack, flat, and running the dishwasher for a bit. If there is no water on the top (or the bottom) either the top sprayer or the sprayer arm underneath the top rack is not getting enough volume.
To fix this you need to clean out the screen and filter, where the water returns to be recirculated. If you don't have any confidence to remove the parts and clean it out yourself, get an appliance repair person to do the job.

Top Rack not cleaning


If you have the model with a garbage disposal, more than likely the chopper assembly broke. It's a fairly straight forward fix. Sears part# 8268383.

Top rack arm doesn't spin.


matt, did you get down to the chopper screen? If that screen is clogged the flow to the upper arm will be restricted. Check out the pic, Catriver
