DW Auto programmes : do they always work ?

[mrboilwash]

Good point !
Not beeing able to detect tomato sauce in the prewash is just another disadvantage of my Bosch`s auto programme.
It takes at least a tablespoon of majonnaise to make it pump out the prewash water ;-)

Variospeed and Turbo can beat hi suds

High suds in DW are due to certain kinds of soil such as milk, meal and raw egg. There's no way, those need a lot of water to be diluted.
If some survive in the final rinse, the foam-action is enhanced by the rinse aid and spray arms go on strike .
In commercial dishwashing everything is prerinsed before loading for this reason, as rinse water is reused to wash the next load

Now latest Miele (miele-presse.de) claims to run "auto" with 8L of water.... my old miele G507 sucked 10L at each fill, but we never prerinsed and never had foam issues
The fault is is due to the A++++ struggle. A glass of water and a day-long programme @ low temp et voila, here you have the extreme eco-friendly DW
There should be the middle course

Semi-commercial mieles PG8050/1/2 are rated C-A-A not by chance, but to work fast and best
As Alex wrote, now we can go back in the past and run old style programs when required, thanks to VarioSpeeds and Turbos

My 4 year old Bosch doesn't have VarioSpeed as such, just a 'reduce time' option. Would this boost water levels and spray pressure? I've used it in the past, but never noticed much difference.

Rolls

Check on the manual - If it says that *reduce time* involves little higher comsumpions, probably it does boost

If your dishwasher, Rolls, uses both washarms all the time, without *reduce time*, so the water consumption will not be much higher.
My dishwasher also has VarioSpeed using both washarms, when VarioSpeed is selected. When not, it just alternates and only one is running, while the other is pausing.
I know the exact comsumptions of mine, when VarioSpeed is selected. If you are interested in that, just say and I will tell you!

just say and I will tell you!

Okay, I'm asking!

Thanks.

We have the Reduced Time option, too. Actually, they call it 1/2 Load. It does not cause more water or heat to be involved. When I use ECO 50° with 1/2 Load it'll cut the pre-wash. I have not noticed much of a difference adding 1/2 Load to any of the Auto cycles - but then I don't sit around in the kitchen for two hours listening to the dishwasher.

I once read, varioSpeed increases consumption by 25%. Here's a chart showing energy consumption in kWh of our Siemens. The two ** mean entering water had approx. 25°C (during the summer). Oh, and I have Intensive Drying enabled.

Reduce Time

According to my Bosch manual, the description is as follows:

"You can reduce the running time of automatic programmes. An optimum cleaning result is still obtained as both the water and energy consumption is increased."

There is no 'half-load' function on my machine, SGS 09 L 08.

I set the dishwasher in motion with the 'Reduce Time' option set to 'On'. The 'Auto Super Wash' programme was selected and the usual 'Finished in 2hrs 14 mins' changed to '1hr 46 mins'.

There is very little difference, the spray arms still alternate between the lower and upper baskets.

The only time both spray arms turn together, is on the pre-rinse regardless of whether 'Reduce Time' in on or off, and even then they only turn together for a short period before the diverter valve switches to alternate mode.

The pre-rinse which normally takes 20 minutes took 15 mins instead with 'Reduce Time' set to 'on'.

The main wash which normally lasts 40 mins took 25 mins.

Rinse-1 took 10 mins; normally it takes around 15 mins.

 

[rolls_rapide]

Rinse-2 took 15 minutes.

Final rinse lasted 16 or 17 mins. It was the usual lethargic, slow spray. My machine must be geared up to protect glassware at all costs!

Drying, which normally lasts 18 minutes, took 9 mins.

So it is clear to me that my machine has no booster function, merely saving time by shaving it off here and there.

thanks 4 all yours suggestions.
Had same Rolls' issues with Zan'olux DW and 2 fridges too.
Just seen that BOL miele costs LESS than MOL BSH, so ...

From a detergent and rinse aid point of view...we use Aldi tablets...their basic 2 in one...and have never had any issues at all....but, they are made in Germany...which my be part of the reason for this
