New Miele G 6000 EcoFlex dishwasher with QuickPowerWash

Miele heat exchanger

The Miele heat exchanger always uses fresh water in the tank, it never re-cycles the water from a previous rinse. It pre-heats the water for the successive portion of the cycle. As in the past with Bosch, the main wash cycle would pre-heat the water for the interim rinse which in turn would let the tub cool down completely.

I know they don't recycle the water. But they use it to heat up the previous water. And thus the question, if they don't do it the BSH way, and it seems to me they don't, they'll use a pipe-kind system. This pipeing could accumulate the dirt in the water, thus creating smell and/or heat transfer issues.

Bosch dishwashers still work that way. After the heating and reheating steps of the main wash are over, the heat exchanger fills with tap water and the temperature in the tank and tub begin to equalize, leading to a smooth temp transition from the otherwise hot wash to the cold rinse.

I have wondered about the effectiveness of the condenser pocket-less drying cycle as well, but I guess it still works well enough despite the tub being covered in Bitumen. My Bosch, with Bitumen and felt all around, still heats the drainboard above it enough to melt butter on it.

I tried searching for the patent of the new Miele system but only found one for a spray arm with rotating jets and a built-in detergent dispenser.

From the instruction manual

This explains how the heat exchanger in the dishwasher works.

Quote from the press release

"This device comprises two separate water circuits in a heat-exchanger unit. One of these circuits transports fresh tap water; the other constitutes a series of loops. The latter contains hot water from the last programme stage which circulates to pre-heat the fresh water in the reservoir."

This does not sound anything like the BSH system to me.

Speaking of Miele: I see that Miele Pro has new undercounter models that look just like Winterhalter models - spray arm, user interface etc.

 

[henene4]

There is a new slimline lineup, with the QuickPowerWash cycle sans the heat exchanger part, cycle times are still slightly longer.

These indeed look too similar to these Winterhalters. But I guess, these are so common, Miele just took the chance to get some retail out of it.

UNDERwhelmed

From the videos to the website, its rather blah.

Its essentially the same machine from the g1000/g2000 range.
Soft spikes? Thanks electrolux.

Marketing more than engineering.

 

[henene4]

But the heat exchange does indeed seem to have an additional port on the diverter assembly.

And it does not have soft spikes. Though it hast the glass holders.
And since the G1/2 series, they changed to all variable speed pumps, changed the cycles arround. So there have been few improvements, but not like a total re-do. Though I don't think there is a reason for a re-do either.

Hey Rich

Our First Miele Dishwasher was a G2220 and when we put it into a rental property we bought a G5715 to replace it.

From a usability perspective they are totally different machines, it really is engineering (Hardware and Software) not just marketing.

The big things we noticed
1) Cycle times, G2220 always around 2 hours, G5715 varies between 90mins and 140mins including 30 mins drying
2) G5715 has the turbo function, can run a load of heavily soiled items on auto in 60 minutes
3) G5715 has the Intensive Lower rack with Auto cycle, can run a everyday mixed load of Glasses/pans without the high temps that cloud/etch glasses
4) G5715 has the new style lower basket, that lets me get 2 rows of 28cm dinner plates in side by side, in the G2220 you could only fit one row
5) G5715 has the 3D cutlery basket, scoops, big spoons and ladles now fit in the third rack rather than needing to sit in the second.
6) G5715 by has the filter housing fixed to stop small pits jamming the drain pump. On the G2220 there was a plastic ring with teeth that you could fit to the filter, by the G5715 there is much more of a recess. (In the first year we had the G2220 we had 2 pits jam the drain pump badly enough that you couldn't remove them from the pump inspection cover. After we fitted the teeth to the filter it never happened again)
7) Silence, you just cant hear the G5715. The G2220 wasn't loud, but you still knew it was on. The G5715 is that quiet we regularly open the door while its running and get a face full of water.

The changes they've made over 10 years are a huge improvement in usability and performance.

I will admit I see some retrograde items in the G6000 series. The G6XXX XXL SCU model has dropped back to the basic racks, whereas in the G5715 XXL SCU you got the mid spec racks. If we had to replace the current one, I'd have to go to the cost of a high spec SCi XXL version to get the flexible racking.

They are like Toyota Corolla's

A skin job but no "new" guts.

Tried and tested tech from previous machines.
I have no doubts the racking has improved but that too is evolution.

On a side note, I have refused to get new plates. Our dinner plates are 22cm in diameter and the cups and glasses are thimbles so fitting stuff in is not an issue.

These "improvements" could have been rolled out with the launch of the G6000 however what would/could be thrown in for the next iteration?

The switch to variable speed style motors is probably due to cost savings (They are much lighter and have less copper and less metal in them. Electronics can be mass produced)
I have a variable speed motor here and compared to an older motor from a G600 the weight and metal used is significant.
I hope they have improved the diverter seals robustness.

re; no new guts

Yeah, sort of like a Porsche also. If it aint broke, don't fix it.
