Tracking of user data

Being "on the inside" of such things now, they can track anything anyway anytime once you connect your machine.

If marketing wants to make some claim, they send someone on the software development team a request to insert that tracking feature in the next app update.
And within 6 weeks, you have your market research data, on the cheap.

I did not realise that it's a Sanitize with oxy cycle.

For such a premium appliance, I am somewhat surprised if they do not include a washing heater.

Load size is a thing there...
It is effectively the size of what an old school TL with agitator could wash, just for non stop washing and drying.

This is how it looks inside of the 24" Electrolux combos with heat pump.

The ELux HWD design

Is very "good" in ways and very "bad" at the same time.

They basically took a simple base washer dryer and bolted the heat exchanger on top.
That made it very easy to design and thus the first on the EU market.

Especially in the EU form factor, making a heatpump washer dryer combo is surprisingly hard.
Heatpumps rely on large heat exchangers and very good airflow, both things that just take up a lot of space.
They made it a tiny heat exchanger and a comparatively high power compressor with the compressor in the bottom of the machine.

Servicing is a nightmare.
Dry times aren't impressive. And it certainly is more efficient than a normal combo.
But nowhere near the potential.

LGs washer dryer combo with heatpump IS very efficient, but even slower.

That gets around the space issue by completely different means.
LG uses a moving drum inside a stationary tub - their "Centum" design.
With that, they can move the whole free travel of the suspension into different spaces - mainly horizontally in the base of the unit.
Thus, they mount fan, compressor and heat exchanger DIRECTLY onto the fixed tub at the top.
Combine that with an inverter heatpump and you get the efficiency you really should be getting.

That however leads to other problems.
The "Centum" system is pretty delicate for balancing, not very water efficient and known to eat socks.

Haier/GE used the fact that the US form factors are a lot more variable.

They took the 27" cabinet, filled it with a "one size down" tub and drum and stretched the cabinet by the height of a pedestal.
They then used the pedestal space as the dryer unit area.
Which in turn means you can have a normal wash unit with typical spin characteristics AND all the space of a typical dryer base unit.

An issue often encountered

With washer/dryers is when they have finished spinning an item or 2 can cling to the drum and refuse to move during shakedown and staying put when drying and you end up with an item of clothing like a piece of card !!

No amount of intelligent programming can stop things sticking to the drum.

Items sticking to the drum

My next door neighbor had the 33" wide Lady Kenmore as well as the narrower Lady Kenmore combos. Sears technician told her to use fabric softener (particularly with the 515 rpm spn seeed for the narrower combo) and that would keep the garments from sticking to the tub. I can say I witnessed garments completely falling in the first couple of minutes of drying.

 

[ozzie908]

515rpm spin

I would imagine they would be holding a little more water the last W/D I used had a 1400 rpm spin and a lot of stuff clung to the drum it needed an arm to swing in and peel everything off lol

Laundry ring protection

There IS a system that checks for that and tries to actively prevent that.
And the one manufacturer doing that is of course Miele.

Since Miele is one of the 2 combo producers that still use the metal electrode plate on the door for drying sensing, they can quite easily detect if stuff is touching the door.

If a non stop wash dry cycle senses a load in the wash, but then in the dry cycle, there is no touch count in a certain amount of time, it runs a recovery routine consisting of wetting the load and spinning it again.
At least, that's what the service manual says.

Miele also limitis the final spin in a non stop wash dry cycle to 1200rpm (max, that RPM is reducible in the settings).
Since it - usually - runs a thermo spin anyway and that is run at full speed the likelyhood is quite minimal it would run into a stuck laundry situation.

Many other manufacturers rely on a few other factors.

Since most use thermal drying sensing, a laundry ring will not cause early drying ending.
Given that most do run thermal spins and combo dry cycles easily run 2h plus, at some point, the laundry will most likely release from the drum.

I would guess that more modern direct drive motors could do some sensing routine to check for a laundry ring formation.
But not sure if anybody does.

Stuck laundry

I had that happen with my hoover 7kg washer dryer, a full load of towels got dried to the sides of the drum completely. I’ve noticed the new 14kg hoover I used they now do slow tumbles during sensing after the final spin and everything then just falls off, however still not anti crease or interval spinning. My sisters Siemens IQ500 washer dryer does interval spinning on any combo cycle, much shorter pause and tumble periods between bursts for gentle drying but cotton drying takes 25-30min to do the final spin since it does very long periods between spin bursts to make sure nothing sticks. It also does near LG stepping motion once the final 1400 is complete and during sensing, then again for about 10min once the thermospin has finished. Gentle drying does no thermospin however. I’ve noticed it stupidly gives up trying to spin if it can’t balance for the final spin easily or the thermospin, when drying bedding, that it’ll just end the prog and you come back to either soaking wet or warm very damp bedding at the end, think it’s happened 4 times in the 1.5yr she’s owned it. The hoover 11kg which had the 13kg drum never had stuff stuck to side, neither the Zanussi I had (though quite old)

GE combo

This was additional current I just got from yale appliances

 

[Chetlaham]

I'll take a combo

Without electronics, compressors, VFDs, wifi, detergent pumps, and complex air flow channels.

 

Give me a bank of 5,600 watt heaters, a 4/16 SPC motor and a 1970s Maytag Bakelite timer. 

 

 

 

 

 

 

[lotsosudz]

Spin speeds?

I wonder what spin speed it operates at on a regular load?
Hugs,
David

 

[appnut]

David, max rpm spin is 1300.

 

[appnut]

Well I have discovered the model offers "Sanitize with Oxi" which means there is no onboard heater/steam ability during wash, which now precludes me from ever considering this. No thank you!!!

 

[gelaundry4ever]

pumps

Circulation or no circulation pump? Inquiring minds want to know.

The new GE combination washer dryer

Looks like this could be a pretty good Appliance. The video from Yale appliances referenced in post number 28 is just painful to watch.

I can’t stand these guys to get on line that just blather on and have no knowledge about the product at all the stupid questions they ask Etc. like the stupid remarks he’s worried about how well it’ll dry because it has such a large drum ??????

Unless you have a half an hour to waste, don’t bother watching, I actually did have time to waste on Saturday and watch the whole video. Oh my God

Combination washer dryers will eventually be main stream in this country. It doesn’t make any sense to have separate washers and dryers at all.

Test

Attached below will be some of the test results from the same guys. Seems halfway decent.
This machine needs a built in heating element for wash water and a warm rinse option. Towels would likely dry quite a bit quicker.

 

[DADoES]

 
That Yale guy always says various wrong bits of info and detail in his videos.

Dress shirts shouldn't be washed/dried with bath towels.

 

[henene4]

Odd

Why this does not have a built in heater is beyond me.
It has pretty advanced controls and a hefty price tag - adding the relay and heater can't have been such a big challenge?!?

That's one of the things I don't really understand why apparently no heat pump combo does - for a "speed" drying setting, you could just cycle the wash heater during drying, much like a DW does during drying. Sure, eats into efficiency, but cycling it even to 500W or 250W equivalent heating power could get temps into the 100-120F range faster, kick starting drying.

It does have an "Extra Hot" temperature setting though that supposedly uses 100% tap hot water.
But explicitly states it does not heat the water.

 

[appnut]

Exactly Henrik!!!!
