Water Pressure at Your Dishwashers

[lavamat78800]

Hey there,

15 minutes ago, I loaded my Bosch up with many items-a real BOBLOAD
I started the Auto 55-65°C cycle, the machine drained, filled and the washarms started rotating.
5 minutes later I noticed a rattling noise..I opened the dishwasher door to see what´s going on inside.
I removed some items, started again, no better.
I did so for about 5 times, until I noticed a plastic cup not sitting perfect, it obviously was rattling while washing.
That´s really annoying!

Is the water pressure at your DW´s also such strong that plastic cups and other light items turn over or rattle?
In my old AEG I never had problems like this.

Nino, for almost all of us here in the US, we're pretty used to this being normal because, until the last 7-10 years, our dishwashers used lots of water and had very powerful pumps. This made things rattle, clink, and plastic items completely flip over or flip on their sides. Now with the tall tub, small pump, 1.2 gallon amount of water per fill, dual pump new dishwashers, it's rare there's enough spray power to flip plastic things over or make things rattle. But, the load still manages to get clean, amazes me at times, with this much gentler sray that has cycles run from anywhere from an hour to 3 hours.

I have the same machine and the same pressure. I had that problem too but I got used to it and now I install plastic items so that they can't rattle or turn over. No probs any more.

Water pressure

Yes, ain't it great? Those B/S/H have an amazing water pressure. I've seen it a few times when I watched the machine wih the door open (and the front covered in cling film): the lower spray arm shoots the water all the way to the top - I love it. I've even had small items in the cutlery basket ending up in he filter after the cycle - eventhough I had the cutlery basket cover closed. And all that with less than one gallon per fill.

When we still had the AEG, it was always "risky" to stack items, as they often wouldn't come clean. The Siemens is just so much better: even baked-on stuff is almost completely removed after the prewash. Only disadvantage is that you can't put delicate glasses in the lower rack - despite the designated two glass holders - because the water spray knocks them around.

Here's a still from a video I made: I know it's hard to see but you should be able to "identify" two water jets in the middle of the picture and water bouncing off the ceiling - that's the pressure from the lower spray arm.

how're they able to be so quiet with that pressure?
that's how the American brands are quieting their machines. just turning down the pressure.

weak, weak i say.

Our Siemens is rated 44 dB. Basically, the entire machine is insulated from top to bottom. First, there is a thin layer or IIRC tar baked onto the tub, then a thick layer of sound absorbing material (not sure but I think it's felt) and finally stainless steel panels on the outside. The buttom (pumps etc.) is fully encloded, too so that noise and possible leaks are caught inside the unit.

I've already put delicate glasses in the lower rack and they didn't knock around. no probs here. It is all a question of how you fill your dishwasher

 

[logixx]

Well, I guess Bob-loading is the only way to fill a dishwasher, isn't it?

The glasses were fairly large yet light-weight so the water could easily move them. It took some time until I got it right.

I never had any problems with fine glasses, such as glasses for Sparkling.
I put the prickles in the lower rack slant, so the water can run down of the wells.
I install them to stand freely, so they can´t rub on other items.
When I run the dishwasher the first time, my parents were shocked to hear that rattling and beating noise.
That noise made them think the DW would be broken..I also was a bit disappointed.
But now I know how to load my dishwasher and am completely satisfied with it.
It´s fun to stack items on top of others and they still get clean.

My mum doesn´t like the dishwasher as she has problems with the interior and the racks.
But I think she´s going to get used to it and shefinally will love it too!LOL

Have to say I'm not too in love with the racks as far as glasses are concerned. I actually liked the top rack of the AEG better: it securely held up to three rows of tall(er) glasses, while the Siemens only holds two. If I could exchange the utensil rack in the upper basket for something to securely hold long-stemmed glasses - that'd be nice. Overall, the Siemens is the better dishwasher, though.

Dunno if my mother likes the DW or not - and it doesn't matter, actually. Other than for the past couple of months, she never had to use it (or any dishwasher for that matter), since I've been doing dishes ever since we got our first dishwasher when I was 13.

Here's the load in question. Took some fine-tuning to get the glasses to stand securely. The top is already filled with other glasses.

Bosch top basket

With my Bosch, I think it would be better if the folding shallow saucer rack, was able to fold at several angles in order to accomodate glasses at an angle (similar to the photo above, of the rear racks in the lower basket).

If my machine has been jam-packed, I sometimes put the handle of a utensil under the saucer rack, to put the rack at an angle to allow water to run off the glasses/mugs.
