Question about Dishwashers

Why is My new Bosch dishwasher leaving black marks on my dishes?

The marks look like charcoal has been scratched onto the clean dishes. You can scrape them off,but they almost look like a baked on mould of some sort. I have never heard of anyone else having this problem. Frustrating considering how much we paid for it and it had great ratings.

Is it perhaps coming off the racks? Are they black? Did they come with a plastic covering that has not been removed? Otherwise I would imagine it could be the rubber seals around the door. Have you tried wiping all around with a white cloth to try to establish where it may be coming from? Door or drawer?? If it is a drawer style unit, check the rollers are clean, they may have been over zealous when greasing them...

SOURCE: Bosch dishwasher

Although I previously posted with the same problem of a film on the dishes after cleaning, I did find a section in the owner's manual which solved my problem. Lift up the rinse aid cap on the inside door - the factory setting is on "4". The rinse aid works in conjunction with your local water, which has variations in it's hardness or softness. When your dishes are streaky, lower the rinse aid setting to 1 or 2. If your dishes are spotted, raise the rinse aid setting higher.

SOURCE: Dishes and glasses being etched; looking dirty; embarrassing

First of all, if you're talking about actual glass as opposed to crystal, glass can etch easily. Why? Because like crystal, there are variations in its quality. Cheap glass will etch faster with the use of an electric dishwasher compared to higher quality glass.

Did you know that the main constituent in most automatic electric dishwasher detergents is sodium hydroxide (lye) and chlorine bleach (another caustic acid)

A Bosch dishwasher has very long wash cycles, further exposing your dishes to the possibility of etching damage. You should stop using the sani-rinse cycle if there is such an option and switch to a gel format detergent as opposed to a powder. Use a rinse agent such as Jet-Dry. This should solve your etching problem.

Dirty dishes & not draining properly


The problem is most likely that there is still water residue at the bottom of your machine. If the machine is not fully drained it picks up some of the residue and sprays that onto the dishes during the final rinse, leaving an unhealthy and unsightly film on everything.
Remove the bottom strainers and make sure that there is nothing obstructing the outlet pipe and the pump. If possible back flush through the outlet pipe and try draining the machine again before using it again.

We had the same issue with a new Bosch. We called a technician out and we were told we were using too much dishwashing powder. He recommended Cascade Action Pacs....they work and we now have clean dishes.

Not cleaning dishes


Our Bosch does a pretty good job of washing dishes. But we rinse most of the time. Not a hard rinse, but a rinse.

Are both spray bars rotating? You can test by seeing that the bars rotate easily by hand, and also by starting a cycle and opening the door real quick when you hear the spray hit the door.

Make sure the spray bar nozzles are all clear.

Has it ever done a good job of cleaning dishes?

DI you leave a heavy build-up of food on the dishes, and allow it to dry before washing?

Just bought a Bosch dishwasher and we were told that they have no heating mechanism to dry the dishes, which is why they are more energy efficient.  You are supposed to leave the door closed for at least one hour after the cycle is complete.  The heat that has built up inside during the wash cycle will dry the dishes.  It is also recommended to always use JetDry. If you follow this advice, the dishes will come out fine.

Dishes are not coming out fully clean


first if the pump is running and you can hear it washing it should clean now hot water cleans dishes not the washer the hotter the better at least 130-135 degrees modern dish washers use less water than older models so if you don't get the water as hot as you can stand it at the sink before you turn the washer on you can fill it with cold water second its important that you use jet dry and if your dishes aren't dry at the end of the cycle then on most washers you can turn the disp up for more hope that helps let me know

Dishwasher not drying


Same problem here. I read the manual very carefully. "OptiDry", "ExtraDry", "EcoDry", "condensation drying" -- lots of fancy words to cover the simple fact -- they DO NOT DRY the dishes. There is no heating element. I wish they would just state this up-front. Air drying the dishes for 24 hours after each wash is not workable for most users...
