Question about Bosch 24 in. SHY66C05 Stainless Steel Built-in Dishwasher

2 Answers

Dishes and glasses being etched; looking dirty; embarrassing

My Bosch SHY66C05UC/14 is etching my dishes; i.e. my glasses look dirty and have scratches on them. Even my plates look like they have a film on them. Not all of my dishes get clean, either. I use the recommended Cascade and rinse agent. This is my 3rd dishwasher in this home in 7 years; the Bosch due to a remodel. I have less success with the Bosch than any of the others. Please help. - Lisa

    Thank you. You've given me more information than Joel at Bosch did this morning. I do use the longer cycles so will reduce the cycle I choose. I use glass and crystal. I haven't had this problem with any of my past dishwashers so don't believe it's the glass ware. My plates and flatware are also being left dingy and etched; embarrassing. I do use Jet-Dry. I was told by Bosch to use Cascade; a teaspoon of the powder, which I've used since we bought it. Joel told me to try Dishwasher magic or Finish Dishwasher cleaner, too. I'm willing to try that. Any additional thoughts? Thanks for your help. - Lisa

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.

Another suggestion: maybe you are using too much of the "right" kind of detergent. I have learned that this model requires very little detergent; a tablespoon at most. A salesman who has the same model told me that if you use too much detergent the dishwasher will smell bad. That made no sense, but he was right, and it took me a while to figure out how much "too much" is. I tend to operate on the theory "If a little is good, a lot is better."

Glasses have a white, chalky film around the top of glasses


This due in part with the government mandate to remove phosphates from detergent.
Several things can be done to improve the clean appearance of your dishes.
1. Start a wash cycle with no dishes and no soap. Once the wash cycle has stated and water is circulating,open the door and pour in one quart of white vinegar and resume the wash cycle.
2. Use a detergent named FINISH.
3. Use only the recommended amount of detergent.
4. Periodically use a product named LemiShine.
Taking these steps will improve the quality and appearance of the dishes.
On a final note: too hot water temperature can cause etching in glasses and only a lower water temp will prevent new glasses from etching.

Glasses marked in dishwasher


This is etching caused by your water source and detergent.
Begin using a detergent brand called FINISH or ELECTROSAL
Also use the LEMISHINE product to clean the dishwasher internally.
If you can not find LEMISHINE,start your dishwasher normally and with NO dishes. Once it starts add 2 cups of WHITE vinegar to the wash tub and let the machine run a full cycle.
These steps should produce cleaner dishes and no etching.
It will not remove etching from existing glassware.

It just starting sparking when I put any porcelain dishes in to re heat. Sometimes a glass mug with etching on it. Not consistent. I put butter in a porcelain dish to warm & it was ok sometimes not


The sparks are caused by metal content in the porcelain -- this is variable from dish to dish. The decorative "etching" which is sparking has metal in it as well.

Etching on the glass ware and the dishes don't come clean.


Dishes may not be getting enough rinse water. Had the same problem before I replaced inlet valve. My fisher packel was 3.5 years old before I replaced the inlet valve due to a knocking noise, but It still ran through cleaning cycle without any alarm codes.

Hi,

The scum, film and white residue problems have started since the reduction of phosphates in dishwasher detergents.

Dishwasher Residue and Film on Dishes

Dishes are no longer cleaned properly. They have a white milky film BUT if hard water is the problem, why were they coming out perfect for the past 8 years?


If the film is only on glass. wash the glass with a citrus cleaner, if they get clean then your glass ware may have been etched by your had water and the detergent from your dishwasher is staying in the etched glass.

If this is not the case, then your dishwasher might not be getting the proper volume of water, witch will decrease the pressure of the wash arm or your spray arm might be dirty.

My dishes come out with cloudy film on them.


From Whirlpool:

*Film is due to either etching or silica film. Silica film is a milky, rainbow-colored deposit and etching is a cloudy film. Sometimes there is a water/chemical reaction with certain types of glassware.
o Silica film and etching are permanent and cannot be removed. Both can occur in any automatic dish washing machine and result from a water/chemical reaction with certain types of glassware. They are caused by some combination of:
+Soft or softened water.
+Alkaline washing solution.
+Insufficient rinsing.
+Dishwasher overloading.
+Heat of drying.
+Long/hot cycles.

To slow the down this process:

*Use a minimum amount of detergent but not less than 1 tablespoon per load.
*Use a liquid rinse aid.
*Under load the dishwasher to allow thorough rinsing.
*Do not use heated drying.
*Wash glasses by hand.

Do the following:

1. do you use a rinse agent
2. clean out the drain.
3. if you have a food disposal, run hot water through it and turn it on to clear it out before you turn on the dishwasher. The dishwasher drains into that sink. If you notice food or dirty water backing up into you sink when the dishwasher is draining, then the sink could have a minor clog and is backing up and being re-sprayed onto your dishes.
Source(s):
Use SANIVAC to clean lime deposits and extend the life of your dishwasher. If you have heavy water.

Run your dishwasher empty and pour in a cup of bleach and a cup of white vinegar to get the residue out.....run a regular cycle.......How hot is your hot water tank set on? The hotter the water the better a dishwasher washes and rinses, be careful it's not to hot as your shower and other sinks also will get this hot water......cut your dish soap down and make sure to use a Jet Rinse Aid. Again, be sure to use a liquid soap, and rinse agent, powders will cause a caustic reaction. Hope this helps. Let me know if there is anything else I can help you with.

I have a GE, PDW8600 Series, problem is - no matter how I arrange dishes the top rack always has deposits left on dishes that are on the top rack. The water is plenty hot.


If your dishes or glassware appear filmy or spotted following a complete wash cycle, adjusting the amount or type of detergent you're using and adjusting your hot water heater's water temperature may solve the problem. But before you do either of these, put a rinse additive (such as Jet-Dry) in the rinse dispenser to improve the sheeting action of the water.
GA_googleFillSlot("HT_Appliances_Dishwashers_Articles_Box_Top_Left_ATF_300x250");

First you'll have to determine whether the film is removable or permanently etched. To do this, soak a glass in undiluted white vinegar for about 15 minutes. Or, you can wash the glass with warm water and concentrated dishwasher detergent or use a high-phosphate detergent (such as Glass Magic) according to label directions.
If film comes off, it is probably caused by hard water minerals, improper amounts of detergent, or unsuitable water temperature. For more, see "Dishwasher Doesn't Wash Well."

Permanent etching is often caused by a combination of soft water and excessive heat or detergent. If glassware is permanently etched, there isn't anything you can do to make it clear again. But you can avoid future etching by taking these steps:
1) Be sure hot water entering the dishwasher is no hotter than 140 degrees F. Don't use extra-hot settings, such as "Power Scrub," and use the "Energy Saver" dry cycle.
2) Adjust detergent amount.
3) Don't pre-rinse your dishes before loading them in the dishwasher. Food particles on the dishes actually help the detergent and drying agents clean better.

Dishes have soap residue despite using rinse aid. Machine is quite abrasive on coffee mugs etc. Unit is Fisher & Paykel DD605SS


use less soap.....excess soap in the rinse cycle will not allow the dishes to rinse properly causing white etching on the glasses and the dishes will have that gritty feeling
