Hi everyone,

Miele is launching a new G 6000 series dishwasher with QuickPowerWash programme. This cycle has been tested to provide 'A' rated cleaning results in less than one hour. This programme has been in their W1 series washing machines for some time now.
Temperature is 65 degrees (149 deg F) for the main wash and final rinse. It does do an interim rinse. Total water consumption is 11.5 liters (3 US gallons)

New basket design elements have also been introduced for even better stacking.

Thanks!

Hm, sounds like Miele got some inspiration from BSH with the way they are preheating the water and the cycle is almost identical to the 55-minute Fast 149°F cycle on mine.

Look forward to

trying the dishwasher tabs.

Is this where the magic is?

However, the ingredients don't look to out-of-the-ordinary.

Rod,

The NZ and AU G6000 dishwashers don't seem to have the drying condenser anymore. Is it just us down-under who miss out or is it everyone?

Why do NZ and AU machines have different operating noise levels to the UK?
Different ways of measuring or more noise for us down under too?

I think the condenser is only available on the PG models. I have a service manual from a few years ago and it already indicates that the condensers were removed and that air is simply blown around the tub during condensation drying.

I did look at the manual for the G6997 and see how the Eco cycle got its efficiency rating: 54C (129F) wash, followed by a rinse and a 44C (111F) final rinse. Cycle time is 3:42 with cold water or 20 minutes less with hot water going into the dishwasher. Fortunately, the Eco cycle is the only one running so cool and long*.

* with the exception of the Overnight cycle

Noise levels

mielerod69's profile picture
The machine in the EU measures its noise level using their ECO programme which runs quieter than the AU version. The AU version uses higher pressure spray during certain parts of the programme which affects the noise levels average values.

Turbothermic drying

Is that what the thing on the right is called?
I remember looking at a few different units in the showroom and they didn't have the drying unit under the green felt soundproofing and there was no opening on the underside on the right too.


The new heating system does sound very Bosch.

But no heatpump?
I suppose we'll have to wait to find out.

So far, I think V-Zug is the only company to have a heat-pump dishwasher.

Great picture


However considering how much space this heatpump unit occupies they may be the only heatpump dishwasher maker still.
What a beast.
Extra tall sized with regular sized wash cavity.

Im assuming this machine is like this because it needed a repair.
Manifold gauges or multimeter for this repair?

Thanks for the info Rod on how the noise levels were determined.

Cycle times

These cycle times are way longer then the "previous" line-up!

Automatic is now 2:05, up to 3:21, but final rinses on that cycle can reach up to 70°C. It basicly gained 40 minutes.
Intensiv, Delicates as well as Normal seem to have grown by something like 30 minutes, power and water consumption seem to be barely improved.

I'm really interested to see if they change something about the SlimLine models as well, but it seems not quite a major improvement, nor a step back.

I'll stick with V-Zug and their 3 kW heater.

3 Things I don't like about the VZug

1. Only an,optional prewash on Intensive.
2. Consistent low final rinse temp.
3. Low temp range on the Automatic cycle.

However, cycles are incredibly fast. And well selected.
But, one thing I love about Mieles still: The nuclear wipe out Intensive cycle.

I *think* switching the AutoOpen function on the Zug off, could increase the admittedly low final rinse temp. The manual makes it sound like this by saying that automatic door opening gives optimal drying with lower energy consumption. Turning it off also increases cycle time.

2 questions:

1. Do you think Miele just "copy-pasted" the BSH heat exchanger idea with the tank integrated into the side wall and heat exchange via recirculating water inside the DW or did they add a special tank where this exchange can take place?

2. Do you think that TurboThermic drying actually got lost on that lineup? (Or did I get the idea wrong in reply #2?)

Both things I highly doubt, simply due to the fact that the manual allows to bypass the heat exchange system for hot water connections and that this machine has a "drain system" operation.
If there wouldn't be a kind of TurboThermic drying (maybe they now cool the whole tank), one key feature of the AutoOpen drying would get lost as well (work top protection via the air stream of the drying fan carrying away all the steam). And with the tank system deactivated, there would be no other drying method then.



Further, the seperate tank idea could explain the longer cycle times: The DW just allows pause time between fills to exchange heat between old and new water. That could explain further why the QuickPowerWash uses the same Energy in 1 hour as the intensive does in 3 1/2 hours: No heat exchange times.

But it adds the question as to how Miele would handle the soil in the water settling down in the heat exchange tank. Though the last water remaining in said tank would be the clean final rinse water, but after the main wash quite a mass of solid food could mess up heat exchange.

This is from a service manual that dates back to the G1000 units. You can see that Miele had already began  dropping the condenser pocket back then.

This seems to be what is in the G6000 units

So how will this work if the new heat exchanger is mounted on the right side?
Won't that mean less space for the fan to blow onto?

I also have wondered about its effectiveness considering the side is covered in thick bitumen (Or something like it)

Miele heat exchanger

mielerod69's profile picture
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.

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.

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.

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.
