[pierreandreply4]

hello to all again i apologize for my question on the bosch dishwasher should i activate the sanitize option or is is active by default because with the pandemic and all even if its dishes i went to be sure there no germ on dishes and my second question is it good to pre rinse dishes before filling the dishewasher i sometime have doubts if pre rinsing first before putting in dishewasher is good?

DWs and Covid-19

No covid-19 could survive any DW, even 100F + The strong detergent will kill any covid-19 almost instantly.

 

With a good DW no pre-rinsing should ever be necessary. In addition pre-rinsing is bad for your DW and plumbing and the environment.

I rarely use the sanitize option.  In most cases, it is unnecessary.  Also, just scrape the large bits off the dishes and put them in the DW.  In fact, The detergent's enzymes depend on the filth left behind on dishes in order to work effectively.

 

 

[sudsmaster]

Agreed, just hand washing in warm water for 20 seconds will kill the covid.

 

That said, I routinely run my Bosch at the hottest and longest cycle (about 2h) with Sanitize. Not because of covid, but because of bacteria, which are much harder to kill.

 

Also, for Bosch and similar Euro design DW's w/o grinders, it's important to get food bits off the dishes etc before loading.

Never pre-rinse dishes ever. Just scrape chunky things off but don't rinse. If you pre rinse your dishes it can shorten the wash cycle thinking all the dishes aren't that dirty, when they are. Plus with pre rinsed dishes the caustic nature of the detergent can etch glassware more easily because it has nothing to work on .I've hardly ever used the sanitize button

Bosch DW Sanitize

I rarely do. My old Point Voyager Whirlpool DW had the sanitize option that was 155ºF, and regularly would rinse at 140ºF. Quite a bit of people have survived using the lower rinse temperature. But our Bosch will actually always run the final rinse to a higher temperature. I think the lowest rinse temperature is on the Auto cycle, and it is 156ºF. A majority of bacteria will die between 150-156ºF as the machine is still heating (~2-3 minutes), so I personally don't find it necessary until someone in the house is ill, then I run the option to ensure it is killed.
However, I will say that the dishes are quite a bit more dry once the cycle is done when using the Sanitize option. As SudsMaster mentioned, I too run the Heavy cycle at least once a month to keep gunk from building up. That 150-160ºF wash makes sure she is in top shape.

Bosch sani cycle

Yes just scrape off large food debris, no prerinsing, leave your door slightly open between washes. My friend has ordered the same Bosch as you and plans on using Sani as others have posted both for extra cleanliness and also to help drying.

We generally always use the Auto with Sanitize option on our Bosch. We only scrape and never prerinse and everything comes out spotless. Opening the door at the end of the cycle allows any remaining moisture to quickly flash dry.

pre-rinsing

If you are pre-rinsing, quit doing it. All you'll do is ruin your racks and dishes over time. The dishwasher is doing a pre-rinse anyway. Let the dishwasher be the dishwasher. It's not a sanitizer.

Jerome, dishwashers have some function for sanitizing dishware.  Sanitized means germs and microorganisms are destroyed to an accepted non-infectious level.

I agree with everything above, however your dishwasher might have a rinse and hold feature… So that would be ok to use if some of your dirty dishes sit idle while waiting for more to be added between loads…

Otherwise why do what’s actually washing your dishes by hand which I despise anyone doing… Your dishwasher no matter how old or new and even regardless of make should do all!

According to the Bosch manual for my dishwasher, pressing the Sanitize option boosts the rinse water temp to pasteurizing 162 degrees F. Otherwise the Auto cycle boosts the water to 153 degrees F, which is still very hot and kills most germs. Notice the Sanitize indicator is lit in the attached picture, even without selecting the Sanitize option. Selecting the Heavy cycle option also boosts the water to pasteurizing 162 degrees F.

But
After you open the door an put the dishes away the dishes aren't sanitized anymore.

 

[DADoES]

 
Sanitization does not require killing or removing 100% of micro/bio organisms, only reducing them to a level that won't cause infection or disease.  No one with an illness coughs on the items, licks them, dunks in a toilet, sanitization is reasonably maintained.

Sterilization is a more intense protocol of killing/removing 100% of micro/bio organisms, including anything and everything that doesn't specifically cause disease.  Sterility is compromised upon removing from a sterile environment, opening a sealed package, etc.

As pointed out many years ago by groups such as Consumer Reports sani-rinse options n domestic dishwashers are of limited use. Once one touches things as they come out of machine and puts them away new bacteria or whatever will soon colonize.

Effort should go into making sure things come out of dishwasher totally clean free of yibbles and other remaining bits of muck. That bit of soil is what germs can feed upon and grow.

Quite honestly it often what goes in and comes out of dishwashers isn't the worry, but rather what grows in or on surfaces (such as rubber seals).

As part of bacteriology lab at nursing school we had to swab and culture various surfaces around lab, classroom and even homes. Believe me when I tell you if you could see what is growing on supposedly clean surfaces you'd never feel clean in your own skin again.
