Yes, you will need to purchase a set of torx style screw drivers at your local hardware store. Remove the upper and lower spray arms and clean the debris out of the spray holes. Remove the screws that hold the filter in place and remove the gunk out of the sump. In the future stop using gels or gelpacks, just use electrasol powder or cascade powder. The gels and gelpacks clog up dishwashers like you would not believe. Run some Lemi-shine through the machine on a monthly basis, Lemi-shine is available at most walmarts.

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.

Bottom water sprayer not spining


If the dishwasher won't clean dishes, check the lower wash arm assembly. If the lower wash arm isn't getting water, all of the dishes in the lower rack will come out dirty. Check to be sure the lower wash arm assembly spins freely. Also check to be sure the little holes in the lower wash arm aren't clogged or blocked.

Dishwasher won,t clean dishes ontop rack


Make sure the top rack is pushed back all the way to connect with upper sprayer arm water port. Also make sure nothing is preventing either sprayer arm from rotating and there is nothing blocking the sprayer arm holes, like seeds or pieces of plastic debris. Also make sure your water heater temp is hot enough.

My dishwasher is leaving a lot of residue on dishes


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.

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!

KitchenAid Superba KUDSO1FLSS3 Not Rinsing? No Cleaning at all!


Hi there,

Here are a couple of things that you can try:

If there is hard water residue or film left on the dishes:
Check water hardness.
If the water is hard, use maximum detergent or try pouring 1/4 cup of Dishwasher Magic into the bottom of the dishwasher. I would also recommend using the High Heat option to ensure proper cleaning. To clean the dishwasher, use a cup of vinegar and place it in the upper rack.

Detergent carryover:
Check water hardness.
If it's below 10 grains, use less detergent and the High Heat option.

It is also possible that you may have a problem with the drain loop check valve as it's not sealing. This may cause residue or food to be left on the dishes. For this, I would recommend you have a technician do it, as it requires replacing the entire drain loop.

Let me know if any of this solves the problem.
