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

Is it important that the engine is inverter?

In my opinion, no, energy consumption will not differ significantly, and such an engine needs an additional electronic module to control it. The more basic models have a squirrel-cage motor with capacitor start, and the only thing that may affect it after many years of operation is the need to replace the bearings.

I'll post the photos after work. But for now, I will explain why the evaporator does not get dirty.
First of all, the entire lint circuit is wet, so there are actually no loose lints flying around. The fluff lands on the first filter, which is repeatedly rinsed with water during drying, together with the evaporator. The flocs flow into the basket, which is approximately half of it permanently immersed in water and constitutes the next stage of filtration. Something like a water vacuum cleaner. Secondly, the water accumulating in the condensate container is circulated up and down the dryer to rinse the system. I think several liters of water can flow through during one drying session. If the container is empty at the start, the process uses the water collected at the bottom of the dryer. And thirdly, from time to time the dryer calls for program cleaning and this process is carried out according to the principle described above.
The inverter motor should be quieter. The noise difference between the 4 and 8 series is very clear, but it is probably also influenced by other factors.

Squirrel-cage motor... yes, but controlled by an inverter, just like in the dishwasher pump heater.

There are two types of motors used in Bosch dryers. Inverter controlled and old school with a starting capacitor.

WQG2410GPL Series 6 comes to my mind, price around PLN 3,000 or WQG233DFPL, price around PLN 3,500. There are many similar Bosch dryers with similar functions, descriptions are often the same but the price differs by +-PLN 300, it's hard to figure it out. Initially, I looked at the 8 series because I like the display panel, but the series has functions such as steam which I probably won't use or AutoClean technology functions which were also advised against in the store. That's why I lowered my prices and I'm looking for 6 series dryers, unless there is one from the 8 series without the mentioned steam and auto-cleaning.

I'm looking for one and my wife says that BOSCH WQG233CRPL is the prettiest

I'm looking for my first hair dryer. Is anyone on this forum still able to tell me that it is better to buy a dryer without a heat pump than with a heat pump, since today the cheapest one is from Bosch:
- with heat pump costs WTH85V0EPL Serie 4 61.3cm 8kg PLN 1,918
- without Bosch WTG86401PL heat pump 8 kg PLN 2,100

This means that for a dryer with a heat pump we will pay PLN 182 cheaper and it still consumes less electricity. Even if we assume that the one with the pump consumes only 20% less, we will save PLN 100 on electricity per year at current prices. Let kWh increase by 100%, we have PLN 200 per year.

But I understand that without a heat pump, even after 10 years, I won't have to call a specialist, and with a heat pump, a specialist for PLN 600 every two years?

Indeed, paying PLN 182 for a device that consumes more electricity per year than a cheaper one seems absurd.

I saw cleaning of dryers with a heat pump on YT, can anyone tell me how much such a service costs from a specialist? Moreover, in these dryers with a heat pump, even the electronics were dirty, etc. Why can't they make it so that the dryer can be filled with water and some agent and rinsed, and the water does not come into contact with the electronics?

Is there also such mess under the casing in a classic dryer without a pump and after some time everything has to be disassembled anyway? Except that the entire pump will not fail, as I understand it, and the exchanger can be removed. Are there heaters in this exchanger?

If it fits your budget, buy it, the wife's happiness translates into the guy's happiness...

Different regions of the country have different rates.
The second issue is that many "experts" do cleaning in shortcuts, any way, as long as it works somehow and they get the money.
This is what one of my current clients did. He paid at least PLN 480 for them to cut off the front cover of the exchanger and wash it with a hose in his driveway. Then they sealed it with silicone. After half a year, the dryer did not dry again.
Proper cleaning basically means taking the entire exchanger outside and cleaning it thoroughly. There's a lot of work involved. Currently, in Poznań, I value such a service at PLN 600 + transport to the workshop.

The mess is the same, only it takes about 30-45 minutes to clean it and you don't have to tear the equipment apart.

michael1986 wrote:

NO. First, it is a condenser, not an exchanger, second, the heaters are built in the rear ventilation duct.

But such cleaning involves not only removing the exchanger and rinsing it with water, but also removing the casing and cleaning everything with a vacuum cleaner? As I understand it, there is no access to the heaters without removing the casing? Does a dryer without a heat pump cause lint to fall onto the floor where it is placed? Is it really worth buying such a device if the prices have equalized and even those with a pump are cheaper?

In the heater, access to the condenser is through an opening flap at the front, so cleaning or washing this element takes up to 5 minutes for a woman. As for the rest, yes, you have to open the casing, but only once every few years.

michael1986 wrote:

Access by unscrewing the rear channel housing, a dozen or so screws on top.

Of course not.

I have already written, it is like an eternal fight between no PB and ON.
Personally, I prefer the heater, it dries much faster, which I really appreciate because it finishes drying before the washing machine finishes the next washing cycle. I am not concerned about power consumption, and the kWh consumption per washing cycle is not much higher than the pump (not to be confused with the energy consumption often given in the device data, i.e. kWh itself).

And such a thorough cleaning of a heat pump dryer by a specialist should be done once every, two or five years? Taking into account that I will wash and dry everything I will wash (160 washes per year).

I don't understand, kWh consumption per washing cycle ! = energy consumption often given in the device data, i.e. kWh itself? Why?

To assess this factually, we need photos of the condenser and evaporator from the front, from the back and above, and with good lighting. Additionally, please write how often the dryer is used.

Of course, the photo can be taken without disassembling it. Well, this is the place that gets dirty first in every dryer. The rest of the element in the inspection camera looks the same. There are only drops of water on the ribs. The dryer is used like in every home to dry everything washed. The next photo shows lint, which in this condition will not dust the device.

My dryer without a heat pump broke down. On Friday. Purchased at the end of 2013.
On Saturday, I bought a replacement part for PLN 18. I had a busy weekend, so the repair won't be done until tomorrow evening. By the way, I will dust it off after all these years of use.

I was wondering whether it would be worth replacing the old dryer with a new one. Taking advantage of the failure, because fewer and fewer of these good dryers are being made.

My family has one heat pump dryer from Candy, which is less than 2 years old. Recently, the drying process looks like this: for about half an hour it shows 0:02 or 0:01 until the end. Is this a fault or is it normal?

I was told in the store that those with AutoClean are the ones that break down and those without AutoClean don't break down. This is more or less what the lady in the store explained to me, encouraging me to buy it. The store didn't have the ones that break, they don't import them because they break .
She didn't have the ones with a heater either.

And what is a man supposed to do now? Should I buy a fancy dryer from AutoClean or listen to the lady in the store?

AutoClean is currently the leading Bosch technology in top models. Previously, there was some, I don't remember the name, that was installed in the 6 and 8 series and there is a lot about it on the Internet. People cut holes in the housing and stood on their heads. I'm not up to date and I don't know what's new in the 6 series, but in my opinion it's a pointless series because it's neither cheap nor luxurious. But as I wrote, I still have the 2018 Series 4 with manual cleaning and there are no problems with it. Of course, the condition is to rinse the filter after each drying.

I wonder one more thing: what is the temperature of the condenser in a PC dryer, not at the very beginning but at the end or in the middle of drying? And it is best to measure NTC on a cable from a multimeter, not with any pyrometers I wonder if it will be closer to 0 or rather around 20-30 degrees? This is a measurement with the device closed in a normal drying cycle. And the sensor was connected somehow cleverly, but in such a way that the device was tight.

I know that it will be quite low at the start, but if these dryers want to maintain a high COP, the difference between these temperatures cannot be too high.

Someone asked how often to clean the "interior" (really very troublesome) in a Siemens (or Bosch) PC dryer.
Reply every 2-3 years. 3 years is the longest I have ever gone without cleaning

Cleaning the interior involves pumping out all the water from the dryer system (together with the lint) - in my case, pumping it out at least three times.
This requires disassembling the dryer, removing the pump, connecting your pump, pouring water from the top and pumping it out at the bottom.
This is what I do every 2-3 years. It helps

And at this point, I'm sorry, but there's nothing else to talk about. We don't know anything about the condition of the condenser, and I've had cases where the evaporator was clogged and the condenser was clogged. And what's interesting, it most often occurred during self-celebrations.

Well done to the seller, she should get the bullshit pusher of the year award.

If you want, I guarantee you that there is no difference in terms of failure rate.

Previously it was called selfcealniny and was basically the same thing.

Borutka wrote:

And this is the basic key to success.

And that's the bottom line, but it's more of a curiosity, because this condition is not a rule, but one of the Bosch pumps with a self-cleaning system was cleaned after a year and a half of intensive use:

>>20834332
I have it once every 2-3 years, but it's a very annoying procedure

Added after 4 [minutes]:

>>20835875
Regarding the photos. From my modest experience, to disassemble the dryer like in the photos, you need at least 1 hour of practice, and for my skills, 2-3 hours. The same amount of time to assemble it

I assume that if there are no (simply no) lumps at the beginning of the road, it can only get better. Perhaps other items are rinsed as well. I can assess the amount of fluff after rinsing by visually examining the water from the condensate tank. The water is quite clean and you can see the suspension when held up to the light, which indicates effective wet filtration. I don't think this filtration was present in the previous self-cleaning system. Moreover, it is not known how the rinsing process was carried out during the dryer operation in the previous system. If any fluff remains on the evaporator after work, it is known that the snowball effect will continue and the water jet will never rinse it away.

If I assumed so, I would have gone like Zabłocki on a soap quite a few times.

Borutka wrote:

The hole for the "flush" is visible in the first photo above the exchanger, but to make it clear, because you have a different model, give me the entire E-number of your machine, I will look in the papers and we will see.

Borutka wrote:

As I mentioned, she had a hard life, and this condition was achieved in a year and a half. The mentioned cleaning with a hammer was previously performed by a dealer or his foreman, this device was from beyond our western border.

WTX87M30PL/03 is also FD:0107, Z-Nr: 2 00216

I watched the rinsing during program cleaning, with the filters removed. When water is sprayed onto the evaporator, water drips from the entire surface. The stream is so strong that it sometimes splashes outside the dryer when the spout is open.

On April 6, 2021, at pepper deals there was a Bosch WTG86401PL 8 kg dryer with a heating element for PLN 1,099 and then it was worth it. And now, when electricity prices are in great doubt and it is cheaper with a heat pump, it may turn out that it is cheaper to buy a dryer with a heat pump every 3-4 years than to buy an "everlasting" heater.

One interesting fact: I noticed that in many stores WTG86401PL is written that it has an inverter motor. Could this be true? Such a combination of a prehistoric heater with a modern energy-saving engine? This is strange because the SIEMENS WT45H25EPL heat pump dryer does not have such an engine.

Get down to earth, man. Do you want to spend PLN 2,000 or more every 4 years? This will not pay off in life, even if electricity was worth gold. For this to happen, the devices would have to consume 100 kW per cycle...

No, this is how stores focus on describing various types of devices.

With a pump, your electricity consumption will be on average 1/3 lower than with a heater.

Gentlemen... I admire your persistence EuroRTV offers 118 dryers, including one without a heat pump. In MediaExpert 176/5 respectively.
I know that the Nokia 6210 and 1.9TDI with unit injectors were good machines. I also remember speculations even here on the forum about no-frost refrigerators.
But the world is moving forward, and even trouble-free Toyotas are breaking down.
Unfortunately, the equipment is becoming more and more delicate and sometimes requires more care, but does this mean that you should not buy an induction hob because, for example, it can be easily broken...?

Why buy a new one, wouldn't it be better to let a specialist clean it properly after 4-5 years? I think that after a thorough cleaning, even for PLN 600, it will work again for another few years. Cleaning is probably not a problem. It's worse when the pump or electronics fails and has to be replaced every few years.

After a long analysis and discussion with my wife, we decided that the best choice in terms of comfort would be the 8 series, specifically WTX87K40PL BOSCH.
We decided that it has everything that will make it comfortable in our use, since whether it has AutoClean or not, it still needs to be cleaned thoroughly. Dryer specialists also have to make a living
The dryer we chose has everything except the Internet. We were wondering if it could be useful to us and we came to the conclusion that no, it doesn't make sense to spend PLN 1,000 more because that's the difference between the 8 series with and without the Internet. Thanks for any tips.
