Dear dishwasher Guru! I have a built in Siemens (in many countries sold as Bosh) machine. the problem is that some glasses got a white semitransparent layer after washing. I tried to remove it with scale remover without success. What shall I do with my machine to avoid the generation of this layer? How can I remove the white layer from glasses?

Please specify the fault seen on the machine

This eventually happens to all glasses in dishwashers, especially if they're lead crystal. Only Pyrex and similar types of glass are somewhat resistant to the problem.

The whiteness is usually irreversible: it's caused by a craze of microscopic cracks in the glass surface, effectively etching the glass. There is only one occasional exception and that's where the fogging is caused by microscopic limescale deposits in the cracks when they're still not present in sufficient numbers to cause white fogging on their own. Adding a cup of white vinegar to the final rinse (if your dishwasher allows the door to be opened mid-cycle) usually clears such glasses, but is not a sure thing as those glasses are already damaged to some degree.

There are dishwashing powders/liquids/tablets which claim to be glass-friendly, but all they do is to delay the onset of glass etching. Even commercial glass-washing machines don't completely avoid the problem, but in commercial use glassware rarely lasts long enough to become cloudy.

You only have two sure ways to prevent this being a problem in future:-

1. Never put valued or lead crystal glasses in the dishwasher and to regard all others as replaceable items.

2. Handwash all glasses.

I hope that my speedy answer has met your requirements; please take a moment to rate my response.

If you have hard water, glasses can look spotted and cloudy even after cleaning. Sometimes changing the dishwasher detergent can help. The easiest solution to clearing up glasses that start to look cloudy is to add some vinegar to the bottom of the dishwasher before you start a cycle. Simply add 1/4 of white vinegar and it will clear up your glasses very well.
You should see marked improvement after the first time you do this. If they are not crystal clear then simply repeat the process until all of the cloudiness is gone. In fact I recommend to using a little vinegar in each cycle to maintain the clarity of the glass.
Note: you can pre-test this by rubbing some vinegar on an individual glass with a cloth. If you cannot remove the cloudiness by soaking it and rubbing vinegar on it then it is possible that the glass is etched due to harsh or cheap dishwasher detergent and vinegar will not solve the problem.

We live in the country and we have white film all over our dishes especially our glasses. My wife ran a cup of vinegar through the wash cycle and it solved our problems. I am not an expert at this but anything is worth a try. I hope I helped you.

We live in the country where the water is very hard and we would white scum looking stuff on our glasses my wife ran a cup of vinegar through the wash cycle withous anything in it and this stopped our problem. I hope this helps.

do you pre rinse the dishes before puting in dw?if so stop and dont use as much detergant

My dishwasher had the same problem. glasses were cloudy, inside the dishwasher was coated with a film, drawers were hard to pull out. tried rinse agents and vinegar and nothing worked. Found lemi-shine at WalMart (it's next to the dishwasher detergent) and the white stuff is gone! no more residue and glasses sparkle again. I was ready to buy a new dishwasher I was so frustrated. get some - it's amazing! a couple bucks and it's back to normal. I was SOOOO happy!

sounds like your plumbing in your sink is going wrong way check pipes or your sink maybe have a clog in it

You need a new detergent dispenser. cheers
