Dishes in upper shelf have food particles

Sounds like either the upper arm is clogged, or unable to move. Make sure nothing is in the way and that it can spin freely. Then, get lemishine machine washer (at grocery store) and run a cycle through - if it's hard water filling the holes, that'll solve it. Sounds too simple - but it actually worked for my exact machine.

this is a maintenance problem.. if the bits look like grains of sand it is actually food particles that breaks down during the cycle spraying the cups and glasses (usually the top shelf that gets hit worst). solution is to run a dishwasher cleaner through the system on a hot wash. To remove and wash bottom filters and spray arm jets. Lastly when loading the DW make sure excess food are scraped/rinsed off ...you will get better results. Thanks

Here is a link to a procedure I put together to clean out your pump. A plugged up sump is the most common reason for poor washing on the upper rack.

Let me know if this helps.

Check your drain filter and clean them. refer user manual for location

Before loading into the machine clean the particles that are sticking to the dishes.

Check the drain filter at the bottom rack and clean. It is user cleanable

check the holes on the sprayer for the upper rack, somtimes they get pluged up and the top rack dishes wont get sprayed off. if they are pluged remove them and wash in a sink

If someone is putting dishes in the washer and obstructing the spray ams that would cause food to stay on dishes. After loading dishwasher and pushing in baskets make sure the spray arm doesnt hit any of the dishes causing them to not clean properly. If that doesnt work or is definately not your problem try removing the spray arm and seeing if it has food inside of it. Some times they get food build up in them and need to be flushed out.

Is the top sprayer clean and not clogged so that the water can flow through? The top may not be functioning properly.

Hi, is the wash arm underneath the upper basket turning freely and is it not blocked with any food particles? I've had items out of my dishwasher with a similar problem and it's been when the upper wash arm has been blocked or a spoon has fell through and prevented it from turning and washing properly.

Good luck.

This was fixed on my unit by taking out the chopper assembly and cleaning the screen. There is full spray on top now. The screen on the chopper assembly actually had some plastic on it that was hard to see, but was blocking most of the holes. Since this was blocked, the pump couldn't pull enough water to push it to the upper spay arms. My chopper was actually broken so it wasn't clearing the screen, so I had to replace it. That will probably help prevent this from happening again, but if you ask me, the unit was designed poorly for handling normal debris that comes off of plates. I'd recommend inspecting this regularly to keep it clean.
