Well, I finally had it with the Bosch EcoLogixx 7 - it's taking it more than 4 hours to dry a normal load of towels spun at 1600 rpm (Not overloaded).

It also started to constantly display the clean filter message despite the fact that the filters were definitely clean so, I am assuming the condenser was starting to block up.

The machine was also having issues with black mould in the condensate tank which is just gross.

As we already have vent ducting in place, I decided to stick the Bosch in the shed and think about what to do with it and picked up a Miele T8722 vented dryer. We had a similar machine for years which sadly died due to someone placing sopping wet clothes into it (it was quite elderly). We should have probably just bought the new motor and parts it needed.

This machine seems extremely similar to it, I don't think very much has changed other than the door is bigger and they've added a honeycomb drum and a slightly newer version of the Novotronic controls.

The difference is like night and day! It actually dries clothes, gently and quickly. It had a load of towels done in under an hour, and it didn't seem to overheat them or cause any issues. It just seems to use loads of air circulation to achieve the results.

Yes, it's going to cost a bit more to run, but I seriously couldn't hack waiting over an hour to dry a few shirts.

Also the Bosch was turning absolutely every large size item into a tightly rolled ball and just not drying them at all which was making it nearly impossible to dry bed linen.

Tried the Miele with a couple of fitted sheets last night and they came out 100% perfect, not even slightly tangled.

I just feel perhaps I got the Bosch 'beta test' version of the heatpump machine, but I was loathed to purchase another one.
 
Well congratylations and salutations!!!

Those Mieles are just best, we have a Miele 8822 Condenser, could not be happier. It is like driving a Mercedes for a few years and then eventually thinking that all cars drive the same way, but then getting into something cheaper, and getting back to the Merc/Miele again you will immediately experience the difference, and I speak out of experience. Yes their parts are rather expensive but there is a reason for that, it simply is superior to the rest.

Well I truly hope that you will have many more years of happy drying! Immer Besser!!

Cheers.
 
The original Miele dryer we had lasted from 1995 until about 2010 when someone (a houseguest) flooded it with very wet (un-spun) clothes that had been removed from a washing machine where the circuit breaker had tripped!

It was a relatively basic, but rock-solid vented Miele with the simpler version of the Novotronic controls (row of vertical row of lights to tell you how dry the clothes were) and cycle selection the older way with a knob that pointed at text printed on the front panel.

I can't remember what model it was, but it was TXXX (3 digits.)

We looked at the repair cost, and because the machine was 15, we decided that it might be worth replacing it rather than repairing it as the parts involved (new motor) was fairly pricy.

A pushy sales person convinced us that the Bosch heat pump was fantastic and we went with it.
It is a bit like going from a very reliable Mercedes to an early beta version of the Prius to be honest.

Maybe the newer Bosch machines have ironed out all the bugs, and I have heard fairly good things about the Miele heat pump dryers, but I just thought I'd stick with what I know worked very well for now.

I suspect I'll get another 20 years out of this machine as long as someone doesn't try to kill it with dripping wet clothes again!
 
Mould in your condenser? I've had my bosch two years and never had a problem with mould...must be something you're doing wrong. Mine is a condenser and I am very happy with it, my dad has a vented version which is good too. Never really had problems with either dryer balling up either.

I prefer vented myself so might as well if you already have a vent in place!
 
I think the problem is the self-cleaning condenser system. It's a nice theory, but in practice it doesn't really work.

A normal condenser's tank is typically full of very clean distilled water. The BSH heat pump systems flush the debris from the condenser (mostly lint) back into the condensate tank. The problem with that is that you are flushing organic material (cotton fibres) back into a tank of water which will inevitably become food for bacteria.

Also remember that a normal condenser dryer also probably runs much hotter than a heat pump version, so you're really creating a lot of issues with warm, damp areas.

The ideal setup would probably have a drain connection and use mains water to flush the condenser once in a while from a connection to the washing machine supply.
 
The problem with using mains water would be that it would eventually clog up the condenser with lime scale. The condensate, as you've said, is destilled water that won't cause those problems.

 

I have used a bunch of condenser dryers in the past and all had fluff residue in the water tank - so it's not just something that happens on the selfCleaning BSH machines, which, by the way, we revised several times since they were first launched.

 

With that being said, in an ideal world, I'd love a Miele vented dryer - but we have no way to vent and Miele pretty much stopped building them, as there's only one lonely model left on Miele's homepage. :-(
 
Oh certainly! There are plenty of Pro vented models available over here... but only one residential unit. From what I understand, Miele stopped selling vented residential units in the US altogether.
 
I was wondering about heat-pump dryers and how effective the condenser flush feature was. You have confirmed another aspect (black mould) which I thought might rear its ugly head. It is based on refrigeration type technology.

A conventional heated dryer basically sterilises itself as it dries (hot steamy air). The down side is that plastic parts can deform over a period of time, eventually making for poor sealing of the system.

4 hours to dry clothes would absolutely drive me mad, as would the balled up laundry.

Sometimes simple technology works best of all.
 
Good choice!
The Siemens we have is just beyond awful in my books, same issues you've stated and I don't like how the clothes smell after, kind of a clean but musty smell (my mother doesn't notice and brushed what i said off)
I much prefer using my AEG lavatherm dryer or Whirlpool 6th sense dryer during the winter.
My mother isn't overly keen on it and said she's looking at getting a Beko to replace it with
Best of luck Iej
 
Only thing I need to do now is set the water hardness to the ultra low setting as apparently Miele's sensors can misread dryness levels on very soft water

Our water is about 125 to 156 µs/cm conductivity according to what I can find online. I must pick up one of those little meters for testing it they're very cheap, just a simple conductivity thing. You get them on Amazon for about €10.00

You can programme the dryer to measure correctly for very low conductivity water.
 
Well I did not know that you had to adjust the dryer according to the hardness of the water.

Apparently our machine does it by itself, there is a video on youtube regarding the "perfect dry". The machine detects the ph of the water and adjusts accordingly. I might be wrong though.

However your machine sounds rather grand and I hope it will give you years of quality service.

To AEGOKOCARAT, I think that the inner workings of the Siemens and Bosch is probably the same, hence the fact that they ball up the washing.

As for the heatpump dryers I would like to try one but they are rather expensive, but on the other hand electricity in this country is sky rocketing, and a lot of the time we don't even have electricity as our one and only power supplier is in severe financial problems and the whole of the system is just falling apart, but I degress.

Back to the dryer, enjoy drying the clothes and I don't think you need to bother with adjusting the machine for Ph variances, just enjoy and relax in the fact that you now have one of the most reliable, albeit not the most flashy dryer there is!!

Cheers
 
T8822c dryer

Hello All,
I’ve got the condenser version of your vented machine, I love it, my t8822c (Energy rating B) dry’s even and no fuss when it comes to tangled up bedding, the perfectdry has always been spot on never under dry or over dry I’ve always found it to be effective, clean the condenser and wash the filters the first of every month religiously just to keep the machine running as efficient as possible. An 8kg wash load from the WKF120 normally takes around 70 mins dried on cottons normal + low temperature (all my washing gets dried on low temperature) I’ve had the machine now for a while I wouldn’t change it for anything I’ve contemplated purchasing the matching T1 machine but I just cannot justify it as I’ve got a perfectly good machine with 10 years parts and labour

I need to check the water conductivity with a meter. The County Council website have various different levels most of which were 150-170µs/cm but some were 76µs/cm

My area is in a different water authority (City Council vs County Council) so I need to get info from them or just measure it myself.

I think I might buy the measuring device abuser as it would be handy to have for purely geeky reasons.

The water around here is extremely soft though. We get absolutely no limescale of any type at all.

It's mostly abstracted from a river dam and most of the rock around here is non-soluable : granite etc
 
I got around to testing the water 176 µs/cm (microsiemens/cm) which is extremely low but still just above their 150 µs/cm limit
