    Hi textonor


    sorry i was not clear. the dishwasher is not out of the box new. i've had it since july but the residue has been  building up  since i first started using it. the powder is hard  and cake like and has attached itself to the racks and stainless sides of the unit. and on random dishes a grit will remain, as if it has not rinsed properly.
    does this help

    I am experiencing the same problem. We have had this problem since getting the unit, and it is almost 1 and half years old now, and the problem has never remedied itself. We have tried switching dishwashing soap (from powder to liquid, and different brands) we have tried changing the setting on the jet dry dispensing unit, and that does not seem to help - in fact I can't really tell a difference between the settings anyway!

    The dishes, especially visible on the glasses, are starting to get a film build up, looking a little foggy. We also noticed that sometimes the dishes on the top rack do not rinse clean, leaving tiny food particles/residue.

    As I am using the dishwasher for my glass baby bottles - this residue has been a problem!! Re-washing a lot of times by hand and then putting them through again to get sterilized.

    I could use some suggestions!

    I just noticed my dishwasher leaving dishes and utencils with a white residue. This was the first time it has happened after 4 years of daily use. I did switch to the new Palmolive "Green" liquid dishwasher detergent about a month ago. I wonder if that has anything to do with it.



    How do you "clean" a dishwasher? I heard of putting vinegar in a coffee machine...would that work with a dishwasher?

    The powdery residue started appearing on dishes after about two years. I try rinsing them in the rinse cycle, but it remains on there. Liquid soap, no construction going on in the house...

The is a new product out called the dishwasher filtration system. it actually filters the water going into your dishwasher and leaves your dishes spot free. after the first load i was amazed that the white film was gone and my dishes were sparkling. you can get it at www.dishwasherfilter.com.

Hello Susano, Having been to the plant where this dishwasher is built I know that they test every machine with water in it. This testing is to reduce units needing servicer when they arrive to the customer. My question is this. Is it possible that this white powder could be from some construction done in your home? Since you only say you just got the unit, I ask. I have seen sheet rock dust in dishwashers when work is being done in the home after the machine is installed. I have never opened a new dw from a box and found what you are describing. Sorry to not be of any help.

    Yes it does. Sounds like the residue left over from hard water. See a lot of that in some areas because of high lime in the water and such. You can get a product called Dishwasher Magic to remove this buildup. Also Citric Acid (such as in Tang Breakfast drink) will also remove this. I have heard some servicers have good results using a enviromentaly friendly detergent. They have said it helps to reduce this happening. What is causing it to happen with the Bosch is that it is hitting the proper temps for cleaning. However this will sometimes speedly remove the minerals from the water as well. Happens to my parents old machine. It was totally white inside.

Another option is if you use powder soap. I've seen build-up from soap that just doesn't dissolve. I would suggest run your kitchen sink before starting your dishwasher. Most dishwashers get their water from the sink supply and if you don't run the sink for a few seconds, cold water will enter the dishwasher and not dissolve the soap completely.

I have a Bosch dishwasher. I am getting a very large build up of crust on all the parts to the point that it clogs up and won't drain. This white build up is so thick at places it is past like. Help!


Dishwashers do not drain a such. The water has to be pumped out so it important that you don't do anything that will interfere with the efficient operation of the pump.

1. You need to pull every movable item out of the washer (baskets and the water filter units at the bottom of the washer) and give them a good clean. Then clean as much of the white gunk you can out of the machine. This is a build up of soap residue and may include undissolved soap.

2. Then run the machine while empty through 2 complete wash cycles with maximum hot water temperature to clean what remains out of it. Do NOT use any dishwasher powder while you are doing this.

3. The problem you have can be due to
- poor quality dishwasher soap powder being used or soap products completely unsuitable for dishwashers are being used
- too much soap powder product is being used
- the water temperature in the machine is far too low. In that event the water heater unit in the machine may be faulty.

Whatever dishwasher powder you are using I would change and buy a better one and also use less than what you have been using in each wash up to now. I would also STOP the machine in the middle of the wash cycle, then open the door and check the water temperature. It should be so hot a wall of steam should rush out when you open the door.

Even after a wash-a white detergent residue is left.


I have a Whirlpool Gold dishwasher and had the same trouble. I found the solution. Fill the detergent dispenser to the top with Cascade Complete liquid gel - it is in a green bottle, then put a half a cup of white vinegar in the bottom of the tub before you start the dishwasher. I have tried them all and Cascade Complete Gel works best. Don't use powder. It really builds-up on my dishes and only the gel keeps the film off my dishes.

I also add Jet Dry in the rinse-aid dispenser but I have a friend who use vinegar in that too. The dishes come out sparkling clean with no film or white build-up. If they still are filmy after three washes using this method, then you may have some build-up in the dishwasher and you can put a cup or two of white vinegar in the bottom - with no detergent or dishes and wash and rinse well. That helps get rid of build-up.

Dishwasher leaving white powder residue on dishes. Why and how to fix?


I have a Bosch also with a similar problem. I cleaned everything that I could (lower screen, etc.) and still had scum. I do have hot and softened water and neither fixed it.
Here is a cheap solution. If it does not work, you are out some vinegar. I started the rinse cycle, once it was full of water, used 1 cup of white vinegar dumped it in the bottom of the washer and ran it through. 20 min. Then ran another rinse cycle to wash it down. Next load came out 5 stars! Just like new. The vinegar can be corrosive if left in there for a long time, but it breaks down a lot of the mineral build up. Very acidic. Hope it works.

My Bosch shu 42 just stopped cleaning. there is soap residue also on the dishes. It doesn't seem to be getting really hot water. We cleaned the filter and made sure it was loaded correctly.


When the heating element fails on dishwashers, the wash cycle water can not be heated high enough the activate the DW detergent powder.

Replacing the heating element should fix you right up.

Also, resist the temptation to switch the a cheap, generic powder. A brand name e.g. Electrosol or Cascade powder is proven to work well. The ultra-cheap powder will leave white patches on the dishes and it will not dissolve completely, even when the heating element is working properly.

Good Luck!
