My Dishwasher keeps leaving food bits on items in top shelf - HELP!?

Question

I have a Bosch Dishwasher which is about 3 years old. Over the past month or so I have noticed that when cycle has finished, items on top shelf (mainly glasses) are left with varying degrees of food scraps. I have tried cleaning filter and also have bought commercial dishwasher cleaning products to no avail. It also happens to some of the bottom shelf items occasionally as well. Any suggestions?

Answer 1

for all the misconception that is out there, the impeller in a dishwasher will not grind much!!!! if you ever saw how tiny it is and, how loose the chamber that it spins in is, you would understand. it will not grind steak or chicken scraps until they rot and breakdown, in the meantime they sit in the d/w sump. they are more for mushing up tomato chunks from sauce left on a plate that didn't get a brushing before it was loaded. scrape your plates into the trash and then rinse them with hot water and a brush before you load them. it will be easier than trying to get encrusted food particles off of you glasses and plates after they dry. good luck.

Answer 2

I would recommend using a commercial dishwasher cleaner to clean the mineral deposits and soap residue from the internal workings of the machine and adjust the water temperature so you are getting at least 130 degree F. water in the dishwasher. It is always best to run the hot water in the sink until it gets to be the hottest available before you start the dishwasher so you at least start off with good hot water. Water temperature has a lot to do with the end results.

I have a Kitchen aid and it has a food trap that grinds the food scraps (like a disposal). Maybe yours isn't working or your just not cleaning well enough before loading.

Leave it empty and run cleaner through it once. Then again run white vinegar through it.

Just remembered, my Husband is a toothpick freak, and one got in the drain line and caused havoc. The thing clogged and ran over. You might have something caught in a line some where. Not allowing it to drain as quickly as it should.

I think I would pour vinegar over the holes in the arms that spray the water, if you have hard water , the tiny holes might be slightly clogged.

Top Shelf Glasses

Answer 5

That is truly strange. I have had similar problems with my machine but usually because it's too full and can't clean everything properly. Do you have to add a rinsing agent to your machine or salt? (that's what I have to do on my machine for reasons even I don't know). Since the commercial cleaning products you tried didn't work either, I would check your warranty and have it serviced.

Answer 6

1. Muesli bars, 2. Canned tuna, 3. Instant noodles, 4. Wholegrain crackers, 5. Popcorn seeds, 6. Canned tomatoes, 7. Tomato sauce, 8. Pasta, 9. Canned lychees and 10. Nuts.

Answer 7

I had this problem twice and draining and cleaning the filter along with cleaning the hard water deposits fixed it. We also ran 2 cycles with CLR. My husband drained something underneath it and it's fine now.

Answer 8

i find topping up the salt container can sometimes help this or buy a detergent that contains salt and rinse aid. sometimes this happens if the dish washer is over filled or the delph is very dirty going into the dish washer. try rinseing the plates under the tap first

Answer 9

Clean the filter in the bottom of the machine.

Oh dear,Oh dear!.If you take the time to read the operating instructions I can pretty well guarantee it will say something along the lines of "Rinse dishes before placing in the dishwasher.",sounds simple but TRUST ME IT WORKS!!!.
