Automatic Washer - The world's coolest Washing Machines, Dryers and Dishwashers

Help Support :

Really? All of them? It looked quite a new thing in the bosch website...
Didn't know of that, so mine should also have it, funny enough never noticed of that, it always looked it filled cold water even though I have never opened it after the wash to see what water comes in the rinse, first (afterwash) rinse to be exact, but I know it does a warm short rinse after the wash and heater comes on as I can see it kicks on (the bulbs suddenly loose some power) and sometimes power meter would shut off if I am using the microvawe or something else, , then another longer rinse, , and the last long one at circa 60-70 degrees, then drain, fill water and dry by condensation, i also pretty dislike this drying system, not much good as a vented model, especially vented models on the fronts like Miele, not to mention ones with fans that are the top IMO, but one thing it does better than the haier and whirlpol is drying, with the whirlpool I always had to dry all of the stuff with the towel...with the bosch most stuff does not need to, ie pans and dishes..
Glasses and other items comes out with drops on them though..and still have to pass them with the towel.
 
washer111, using the water that is needed to purge the line is a very sensible idea. In my case, and I understand that everyone has different circumstances, I'd have to purge almost a small bucket (five liters or more) from the line and I have no use for so much cold water short of dumping it into the toilet after taking... never mind. ;-p At our old place, we had a recirculation pump and a hot-water connection would have made more sense there. Here, however, we asked out landlord to switch the recirc off because it made annoying noises in the pipes all day long. On top of that, the water cools off fairly quickly - like in ten minutes or so - and I'd have to be standing there purging the line as the DW goes through its cycle.

As aquarius pointed out, Bosch's heat exchanger has been around since "forever". I think it's the company's trademark just like Miele's cutlery drawer. Some of the cheapest models don't have it and special application units, like the counter top dishwashers, don't have it, ether.

The heat exchanger works during the post-wash phase, when dishwashers typically continue to wash without reheating the water. Roughly 15 minutes before the main wash drains, the heat exchanger fills with cold water and the temp inside the tub and inside the heat exchanger equalize. There's no extra energy or time needed to heat the water. This process takes place during every step of the cycle but the final rinse.

Vented drying in dishwashers? It's dead, I'm afraid. Most manufacturers have moved to some sort of condensation drying. I'm not actually sure why, though. For hygienic reasons? Because many people want fully hidden dishwashers these days? I don't mind vented drying - our AEG had it.

As for Maytag and KitchenAid: I'll add screen shots of the manuals for their current dishwashers:

The first one is Maytag's thirsty Pots & Pans cycle, which, by the way, is as fast or slow as the similar cycle on my dishwasher. Don't know what on earth you have to do to get the time up to 295 minutes.

The second picture is from KitchenAid. Seeing that you can use High Temp Wash even on the Though cycle, leads me to believe that even Though washes at 41C (or it might wash at 55C and HTW raises it to 60C).

About your Bosch dishwasher Freddy,

I decided to download the manual of it. I see there are some interesting things about it.

1. The normal cycle doesn't have a heated prewash. But the Pots and Pans cycle has. The prewash is 50 degrees Celcius, the main wash 70 degrees Celcius. After the main wash it has three rinses of which the last one is heated again to 70 degrees Celcius.

2. There is a recommendation in the manual to connect the dishwasher to cold water. If connected to hot water, the temperature of it should be max. 60 degrees Celcius.

3. It looks like there is no heat exchanger in this model.

4. For shorter cycles they recommend only powder, no tabs.
 
Sorry

Louis, I think I told you a wrong number , i looked online as I was not at home (nor I am now) and should have got the wrong one, my correct number should instead be sgs43f02 , my machine has max temperature written next to the program you choose, the stronger cycle do have stated 65 degrees....so it is not the model you got the manual for, I appreciate your effort and if it is not much trouble please look for the correct one...
For istance, my dishwasher is like this

For the record, our machine has vented drying.

 

Not that I let it run when I'm around. I cancel and open the drawer to flash dry, save some time and energy. 
 
I've never understood...

Why anyone opens the door.

 

If you're using Rinse Aid, and your last rinse water, was of a decent temperature, the combination should dry your dishes. By opening your dishwasher door, you're letting all the hot steam & thermal heat out, that helps dry off anything still wet. Leaving it closed, you get powerful and good condensation based drying. 

 

I've always noticed, that if I open the dishwasher door, after the cycle, things stay wet. If I keep the door closed (for at least a couple of hours) everything is perfectly dry, even Plastics. 
 
Why anyone opens the door?

I like to use a cloth on concave surfaces like the bottoms of cups and glasses or any other place where water pools and doesn't completely evaporate. Then I just close the dishwasher again and in a couple of hours everything is really dry.
 
Allow me to Explain :)

For me, it seems to save time and deliver better results - especially on the very hot cycles. In more humid weather, it just doesn't seem as if an environment at high humidity will be conducive to drying. 

 

I also haven't been using rinse-aid very much lately either, just on the minimum setting, and that stops all the spotting. The small addition makes flash-drying much easier.

 

Whilst it does work by letting the fan work, shutting the machine off saves whatever minuscule amount of power and drys everything in about 5 minutes - compare that to a 30 minute wait :)
