Bosch Condenser Tumble Dryer: Comparing WTW85460PL Heat Pump Model and Conventional Options

by cleaning the heat exchanger regularly

I don't really see any connection with cleaning the exchanger. I cleaned the exchanger in the heater once a month or two and generally other places were very dirty - the channel behind the exchanger, around the fan - leakage between the fan and the motor - generally behind the rear casing/duct there was a lot of wet dust and it probably flowed from there - I don't know and I won't analyze it now. I took it apart, cleaned it and that's it.

Unless you want to make me understand that cleaning the exchanger will not prevent this crap from occurring.

I don`t make it clear, I just write directly that you turned the dryer on as far as it would go. And now you blame the dryer

You turned the dryer all the way down.

I have a different opinion - I believe that this particular dryer is in better condition today than on the day it came to me.
The fact is that I carried out activities that an average user could perform, not being aware that such crap could happen somewhere in the back of the casing. Well, when I bought it used 5 years ago, I didn`t believe that it would work for so long, about a year ago there were some squeaking sounds that could be heard from time to time, I even called the guy who sold it to me to look inside, and he said that I had don`t worry about it, because these are durable devices, so I didn`t worry - I didn`t bother with disassembling the whole thing, because I have no experience with household appliances and I only disassembled it completely when I had a new device - I cleaned it, put it back together and somehow it works.

How about the back of the case? Even in your video you can see that you start from the front, in the place where we regularly remove the heat exchanger and clean it:

And this is the difference between a classic condenser dryer and a heat pump one. In the first one, we regularly remove the entire heat exchanger and clean it in a very simple way.

The narrative falls apart.

Nothing is falling apart. The video shows an old WTE86386/30 heater dryer and a view after removing the side casing, removing the inspection flap (0509) under the exchanger and removing the water pump (0512) - you can open this inspection flap after removing the exchanger (from the front), but cleaning is difficult.
Yes, a heater dryer appeals to me more structurally than one with a heat pump - that's why I'm not getting rid of the old dryer and I approach the new one with caution.

I only found out that I had dirt in other places when I completely disassembled the dryer. The chamber in which the exchanger is located was clean - as far as I could reach with my hand, but there was a lot of dirt at the back, where the fan 0507 and under the housing of the fan cooling the exchanger. 0526.

Well it died, model WTH8520SPL after 5 years, like clockwork.

Refreshing the topic:

What dryer do you recommend now, what is the least bad?

@lukiiiii What happened? And why doesn't anyone want to address it...,

So it's not too bad - assuming it cost 2,000, you were paying £33 per month for the ability to dry laundry quickly whatever the weather .
I wouldn't overpay when buying another one.
It would be good if you could let us know what specifically died, say what symptoms, show pictures of the exchanger.

More specifically, I've had it for 5.5 years, a 2+1 family, we dry it all year round.

For a good year it does not dry, we add a manual program first it was 20min, yesterday 120min (!).

About a month ago I took it apart, all the way down to the exchanger cassette, tried to clean it, wasn't happy with the result, put it back together, the only plus is that it started to run quieter. I'll give a picture tonight, how to clean the damn thing????

And that's good advice, a simple model with no superfluous software and so uses up to 2-3 . But are there companies or ingenious solutions that should be avoided more?
Have they come up with anything innovative when it comes to pollen?

I have never done this, I have seen videos of people disassembling the whole thing and cleaning the exchanger with a pressure washer, but in my opinion you have to be very careful because these plates are very delicate and the whole thing is fragile - you have to pull it out carefully for cleaning so as not to bend the tubes. Basically, two things happen with these units - either the exchanger gets dirty or the system loses its tightness and lacks the refrigerant, so cleaning the whole thing does not guarantee that it will work properly. As far as pollen is concerned, there are a number of solutions in more expensive models - whether they are effective and whether it is worth paying extra for them, I do not know - if the manufacturers offered a 10-year warranty, I would not hesitate.
Here is a sample video of exchanger cleaning https://youtu.be/FcCs5vwiDRw?si=r0Ldp-NIqS0S-90U

Another question - before the exchanger you have such a sponge filter

.

How often have you cleaned / washed it? Similarly with the lint filter which is by the drum.... I ask these types of questions because heat pump dryers are, if nothing else, a novelty on the market and I always wonder whether by taking care of these filters the user can extend the life of the appliance in any way. I bought myself a new sponge filter with my dryer (also Bosch) - every 2-3 dryings I replace it with a clean one and that's it, and I clean the lint filter after every drying - and in my opinion cleaning these filters has a greater impact on drying time than on the life of the appliance, but life will tell.

Definitely but I won't tell you which ones, there are certainly more experienced people here. I for one have not had anything other than a budget Bosch for the last 20 years.

I've had a Bosch serie 4 since 2017 and it works without a problem, but unfortunately throwing away the lint and making sure the gasket is clean after each use is a must.
And unfortunately I can see how this is handled by women. As for the male population, washing and drying is not a manly thing to do and most can't even turn on the dryer, let alone bother with cleaning. Also, it is what it is.

lukiiiii wrote:

And this is the normal time for cleaning the exchanger. You have to take everything apart, remove the pump system and gently clean the entire exchanger so as not to damage the plates. A normal thing for any heat pump dryer.
Here a little overview:
https://www.elektroda.pl/rtvforum/topic3864613.html

In my opinion, this material from the link is a description of some pathological situation, because equipment four years old from a normal house, at least from a cursory inspection, should not differ much from new condition. The copy described is more likely to have emerged from the lowered states of the Vistula or served some large locksmith's workshop.
I think this is also probably obvious to my colleague and I don't know what the purpose of the crooked mirror is.

The equipment in question was used by a family of 2+2 in normal domestic conditions in a dry bathroom.
Samsungs just happen to have problems with corrosion at the exchangers. In fact, every single one of them is more or less rotten after five years. However, this was not the point, it was to illustrate to my colleague @lukiiiiii what stage he has to reach if he wants to clean the exchanger properly.

I'm a rather conscious user of all sorts of equipment and I'm teaching this to my family. I started my dryer purchase just by reading this thread.
From the very beginning me and the wife even morbidly cleaned the 2 filters and every now and then the sponge plus vacuuming and, and g.shit it did.

I have been writing about this for a long time, that five filters, 3 sponges will not help much anyway, the exchanger will sooner or later have to be cleaned anyway. This has to be factored into the operation like the timing on a car.

So one can conclude... that if a really conscientious caring user has a problem after less than 5 years, it means that almost everyone should have problems after that time, especially as the less caring ones tend to be in the majority.
It's not that bad, because Poles bought almost 300,000 tumble dryers in 2021 and the trend is probably upward, while traditional dryers are practically non-existent in shops. So, statistically, after 5 years, these nearly 300 000s would end up in service or be scrapped? Probably an exaggeration.

Sometimes one unfortunate event can initiate the destruction of an appliance. My wife once threw in some trash and the first filter was destroyed because the permanent fibres stuck together (melted?) the surface of that filter. If such rubbish is pelting the exchanger, the snowball effect will be that more portions of dust will be caught avalanche by avalanche. There are also factors that can have an impact, especially as, according to the manufacturers' labels, the vast majority of clothes are not designed to be dried. So we need to use our intuition and think for a while before putting them in the drum. Perhaps too often we buy appliances from the lower end of the market, carelessly or provocatively designed where low-quality plastic components lose their stability and tightness over time.

Under the shower possibly make a stronger stream with a finger from the hose. A pressure washer will bend the fins.

And after three months a repeat of the fun only it will be an even bigger problem to clean the exchanger well.

Well, the stupidity of people can be striking. I have a client who works at a PSZOK. Every now and then he brings me some cool equipment to check out and most of it manages to be brought back to life quietly. The most recent was a 2019 Bosch HomeProfesional 8-series dryer. The only defect was a clogged exchanger and did not dry, after cleaning it runs like gold, the guy gave it to his daughter.
Fact, the cheap Chinese g. the guy does not even take, because with these the chargeability is indeed questionable.
On the other hand, people have given themselves a lot of crap and this is the image of the modern world today.

This is a topic for another discussion and big calculations.
A man here on the forum once wrote a wise thing:
"He who buys cheaply, buys twice" and this has proved true in many cases.

After my experience with the LG washer dryer and the Bosch exhaust dryer and after visiting many stores, looking at dryers with pumps from probably all manufacturers, scrolling through tons of opinions and reviews on forums and youtube, I have given up on a pump dryer for the time being. Early on I was thinking Miele or Bosch with AutoClean. Instead I decided on a room dehumidifier (works the same as a pump dryer as it has a compressor and filter, just dries the air throughout the room) + traditional folding dryers. I have an unused room so there is room for traditional drying, the only problem was the perennial damp, dripping windows, even when I unsealed the window. The appliance has a laundry drying programme and also an automatic programme with manual adjusting of the humidity in the room, so in addition to drying laundry I can also dry the house from excess moisture in winter. The price is 3-4 times lower than a pump dryer. Power consumption approx. 200 watts. No clods on the filter, in the drum, no shrunken clothes, 2x less use of clothes, because they are not doubled in the drum with the drum drum filters, no release of microplastics in the form of tons of clods in the filter and faster consumption of already disposable clothes.

I started this topic 10 years ago, I purchased the Bosch WTW85460PL heat pump dryer discussed in the topic at the time.

The dryer has worked all these years and still works perfectly. One fault is the door closure sensor .

I would definitely buy a heat pump dryer again.

I do the same, but this is a solution for people who have the space and want to hang laundry in the bathroom (laundry room), or do not have room for a dryer. Economically speaking, it works out cheaper, especially if you already have a dehumidifier, so the cost of buying one is dropped. Besides, part of the moisture is removed by ventilation, so the dehumidifier only mixes the air and collects the rest of the moisture.

my sister has a heat pump dryer and she told me today that it destroys/shrinks clothes, besides that after every drying process handfuls of dust from clothes gather on the filter (which does not happen when drying on strings), it does not consume little power, the only advantage is that the laundry dried in the dryer is soft, and on strings it is stiff, which I confirm myself

piokrza wrote:

You can talk a lot about this, but the problem with shrinking is one I had with a traditional dryer. Besides, first of all 95% of clothes (also "branded") on our market are of poor quality, on the labels there is a ban of drying in a dryer, and even the washing itself is limited to a delicate program at 30 degrees. So putting them in the dryer is usually an experiment. Admittedly, it mostly works out. On the other hand, I have polo shirts from a recognised brand that shrink after every wash without using the dryer. Personally I used to sort the dryer cartridge, now owning a better model I throw everything in even suit shirts. After such drying they look better and iron better and even the collar stays clean longer.
In the case of your sister's friend, there may still be a dryer malfunction. E.g. because it's dirty and not efficient, she turns up the heat or extends the drying time.

@Borutka says that synthetics and synthetics shrink, so as you write that it's on the label, it's most likely fabrics not meant to be tumble dried at all. I think most people dry their clothes like that in the tumble dryers without paying attention to it. The latter is also possible, as far as I know they've had it for a few years so the capacitor is probably clogged already, although I haven't seen it myself.

piokrza wrote:

shrink.

That is, things that are not suitable for the dryer and that's it.
It's like complaining that a petrol powered car won't run on oil.

In the 2 largest chains covering 70% of the market, in one there is 1 condensing model out of 160 with a pump and in the other 0. Nobody wants condensing ones, what they have taken into stock lies for years, to be sold out.

@Sebastian_M26
What kind of crap are you writing again ?

Sebastian_M26 wrote:

What is a dryer with a pump if not a condensing dryer ?
Educate yourself, boy, because your head is stuffed with merketing gibberish....

I will educate myself, especially about heat pumps and exchanger links, thank you for the reminder.

So maybe as a way of defusing the atmosphere I'll throw in an interesting fact I have a Bosch appliance, a WAN2826EPL washing machine (usually spins to 1400) and a WTH85V8EPL dryer. Dry 99% mix, statistically ~1kw/dry. While it's obvious that manufacturers are sizing up the actual consumption (because as you know everyone uses differently), you never know what to expect. In my case it came out just under 20%, to my eye not too bad. Family of 2, one of which is a bobo.
