SOURCE: dishes not washing clean

check water level in machine
may be not filling enough and the wash pump is starved from water thus not pushing water to upper arm
drain water from machine dismantle and clean out air tube to pressure switch take off air tube at pressure switch and blow back into sump then pinch air tube with fingers to stop air from flowing back up tube then refit to p/s
run and see if that solves problem

SOURCE: upper rack dishes dirty

Is it filling with enough water. Look or if you don't know how much water is supposed to be there , Just add a gallon of hot water to the machine after it fills. If this solves the problem check the filter in the fill valve or replace the valve.

Check the upper spray arm for debris plugging the spray holes, if clean then pull off lower spray arm and filter screen, and clean and remove any debris found in the sump, check the disposal blades as well. You will need a torx style screwdriver to remove the sump screen on this unit. You can buy a set for under $10 at your local hardware store.

Glasses do not come clean in the upper rack but do in the lower. Is there someplace that should be cleaned out to make the upper rack work again


Not knowing what dish washer you have I would check on the sprayer make sure it turns or is not blocked in any way. If the water can't spray up you will not get clean dishes.

Top dish rack dishes don't get clean model 8575637


Most dishwashers have a rotating spray bar underneath the upper rack. Over time bits of food can clog up the holes and then dishes won't get clean in the upper rack. Check to make sure all the holes in the spray bar are clear and that it is rotating freely.

Dishes on top shelf not getting clean


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!

Kenmore 3380957 rev a won't get dishes clean


Make sure that that upper arm is free to turn. Check it while you have dished installed, because sometimes, dishes on the lower rack may stick up too high and hit it. Otherwise, check the back of the water-supply tube attached to that upper rack.... Is it lining up with the water feed port or hole at the backof the dishwasher? Is there a gasket that is either ripped or missing? And check that wash arm carefully.... Might it be split or bent? Are the holes on the bottom clear? (Those holes are usually angled to push the arm around; if they are clogged, the arm won't rotate.)

Dishes not clean?


Check all the water jet orfices in the moving arm. Try cleaning without loading the top rack.

If cleans well, mostly the upper rack dishes not arranged properly.

I hope you are using the main wash detergents. Rinse aid is just to remove the stains after the main wash rinse.

Dishes bottom rack are marginally clean. upper rack is never clean anymore. The dish washer cycles through NORMAL and Dries dishes OK. Motor is running, and rinsing can be heard as well as washing cycles....


Just fixed my Frigidaire. The outboard o-ring on the main pump became distorted and stretched. Check your local hardware store as Frigidaire wants $17.50 + shipping. Good luck
