Whirlpool dishwasher leaving debris on top rack dishes

I've had the machine for about 4-5 years and recently it began leaving debris on the top rack glasses/dishes. Usually mostly on the exterior, but sometimes on the inside of the glasses as well. Technician advised me to increase hot water temperature, change detergent, and add more rinse aid. None of those things have helped. Any thoughts? He disassembled the pump, inspected the spray arms, etc. and didn't find anything unusual.

You did not list the model of the machine. But it appears to me that the disposal in the unit might be in need of work. There are teeth in the machine that grind food.

SOURCE: Maytag dishwasher quiet series 400. Dishes have hard stuck on grit and food particles after rinsed and dried.

Very common problem is soap build up in these machines. Try putting it into a wash cycle with no dishes, and no soap. Let it wash for about 5 minutes, and then open the door. If you see alot of soap suds, then soap build up is the problem. Try doing a couple loads with no soap, and no dishes, and throw a cup of vinegar into the machine halfway through the wash. Repeat as necessary. This should solve your problem.

SOURCE: kitchen aid dishwasher doesn't clean dishes in the top rack

Sounds like you have 1 of 2 problems. Either your pump is clogged or you need a bigger drain loop.

SOURCE: LG dishwasher wont clean top rack dishes

Recommend you remove the approximately 10 screws to pull the entire filter and manually clean. Remove all debris you find and thoroughly rinse out the filter if you can separate the top from the bottom. If the sump area is greasy, use a de-greasing spray to cut through it. Resemble, checking that there are no blockages in the holes on the spray arms.
Fill a bowl or cup with white vinegar and place it on the lower rack of the empty dishwasher. Do not add detergent. Run the quick cycle. The inside of the dishwasher should now be clean and not greasy. If still greasy, use the de-greasing spray (avaiable at all stores in the cleaning section.)
For 30 days, use only Electrosol or Cascade powder. Do NOT use gel or tablets, ever. Please report back your results. Good Luck!

SOURCE: dishwasher not cleaning dishes on top rack

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.

Top shelf dishes aren't getting clean in my 5 year old Whirlpool dishwasher. Any suggestions?


Hello,

The most likely reason the dishes in the uppper rack of your dishawasher are not getting clean is because the filter on the pump is built up withe debris and the water is havinga tough time circulating through the pump. This tip i wrote will show ya how to clean that filter.

Kenmore Dishwasher not cleaning dishes - especially top rack.

The top rack is not longer getting clean


Using liquid detergent is the worst detergent to use. One possible solution to your problem could be as follows...pour 2 cups of vinegar in to the tub and run it on the hottest longest cycle with no dishes in it. May need to do this several times (3 to 4). This will clean the residue out and what ever "gunk" may be in the internal parts. Use Only powder detergent. No gel, no liquid and no tabs. These 2 cause a build-up over a period of time of use and reduce the performance of your machine. This should take care of your problem.

Dishwaher does not clean, upper rack


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 (part # 8268383). If the motor gear is broken, replace the sump and motor assembly (part # 8535150). 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.
Good luck!

LG dishwasher wont clean top rack dishes


If the unit is cleaning the bottom dishes normally, try unplugging the unit for 5 minutes to reset the control board.  If that doesn't work, then the control board needs to be replaced.  The problem is that control board is not diverting the water to the upper wash arm during the cycle.  Possibly a program problem
