Top Rack doesn't get clean


The upper arm attaches to a tube in the back of the dishwasher. If the support clamps come loose, the upper spray tube will not be flush with the tube and can't carry water to the sprayer arms. Also the sprayer arms can become clogged with paper remnants, bone fragments, or pieces of peeling. You'll need to remove the sprayer arm and flush it at your sink. If there is a jet that is clogged, tweezers will help remove the residue.

MY DISHWASHER DOES NOT APPEAR TO BE CLEANING MY DISHES


Your sprayer arms may be clogged.

If there is a jet that is clogged, tweezers will help remove the residue.
Finally, the bottom of the door INSIDE the washer often get covered with gunk. Be sure and gently wash the bottom of the door INSIDE. You can open the door, spray some window cleaner on the bottom and then gently brush away the 'gunk.' Rinse with hot water from a pitcher or your sink sprayer and this can eliminate some of the residue that is showing on your dishes.

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.

Residue inside dishwasher sprayer arms


What it is called is calcium deposits, your water is high in calcium. You may have to clean the part occasionally with CLR or something similar.
You should look into flushing your hot water tank occasionally as well, calcium deposit biuld up after awhile and your water tank has to work extra hard to heat your water, which cost you more money in the long run.
Hope this helps you .

Top sprayer wont spin . dishwasher goes through cycles and only partially cleans. bottom sprayer does spin.


The sprayers are not powered but rely on the water pressure to spin them. If it's not spinning it could be
the spinner isn't engaging in the top rack as you slide it in
blocked jets on the spray arm
blocked feedpipe to the spray arm
faulty pump

Most dishwashers are fairly easy to dismantle to check the first few

My 6 yr old Kitchen Aid dishwasher is leaving food residue


After checking all sprayer arms for clearance, and checking heating element and discharge pump, the problem was solved by replacing the small sprayer arm at the top of the washer. This small arm had popped off some time ago - obviously the water pressure was excessive for the small and unimpressive fastener. Luckily we had saved this piece, which I refastened with a strong aluminum non-corroding small bolt. Presto - now the water distribution is back to design specs, with sufficient water coming out under pressure from the mid level arm. Lesson: always look for the simplest cause first with the simplest solution. TCA

Most dishwashers have a little filter basket in the bottom. Depending on the brand, you can slide out the bottom rack, and in the bottom underneath the sprayer (the propeller thing) there should be some sort of basket that can be removed and cleaned. You also may have some water quality issues, or some detergents will leave residue. Also, make sure most of the large food is removed before loading.
