[@piotrt9779]

Thank you, mate. I just went through this process with my Heat Pump Clothes Dryer, and your guide was perfect for this task. I felt completely comfortable with the dismounting and mounting processes. Here are some lessons learned that might be helpful to others: 1. After dismounting all the elements, I decided to also disconnect the entire front panel of the dryer. There are just a few screws at the front that allow for this. You do not need to disconnect any cables; you can simply move this panel to the side. This provides far better access to clean the heat pump elements. You can also vacuum clean all the dust from the hidden sides. 2. I opted to use a Kärcher SC4 pressure steam cleaner. It worked very well, although even having such a strong tools it took about 2 hours (and several refills of the water tank) to complete the cleaning process. The final result was however worth it. All the water drains into the water container, so there's no issue there. I used a bit of plastic foil to separate other places (like back side radiator) and not allow steam to go everwhere. You also need to be more cautious when cleaning the back side radiator, as it does not have channels for water underneath. But rest assured, the steam cleaner is safe and does not damage the radiator components at all. 3. It's beneficial to dismount the small water pump at the back side as you did and clean the water container, as there's a lot of dust in the water too. To do this, you can place the base on some coasters, tilt the base to pour out the water, and then use sponges, etc. It is also good to rinse it with water. If available, you could use another water pump to pump out the water and clean the container (I unfortunately did not have any ). 4. Screws - there are two types of screws. It's helpful to note which type is where. My observation is that one type is used to assemble metal elements and the other is for attaching metal to plastic. By taking these notes, it's easier to select the right screws in the right places, when you are putting all the things back together. 5. Last but not least, I have added an additional seal around the removable filter because I think it is the area through which most of the dust passes (the original rubber seal is not sufficient). I created it from the type of sealant you can buy for home window insulation. However, this is an element where you can get creative with your own ideas ;-) : prnt.sc/Nf8JNTwNu_ew 6. Some clothes dryers, of that type do not have access to clean the heat pump from the front panel. I advise in such case to invest in the maintenance flap available i.e. on Amazon: Bosch Siemens 646776 00646776 : prnt.sc/smQvZk6wNvq6 There are movies on YT that explain how to mount it i.e. : kzbin.info/www/bejne/o4nJqmWFr9OagK8 I believe this is the best guide on the internet to fix Bosh heat pump clother dryer, and thanks to you, I saved the equivalent of 200 USD ( I double checked it) by not needing to call a service technician. Thank you again, and a BIG LIKE to you from Poland! 💪🙂👍

[@jessegoldswain5973]

You saved me a fortune not having to buy a new tumble dryer. We bought it new in 2014 and use it… extensively. When we moved house in 2018 bright spark over here decided to plumb it directly to the drain thus eliminating having to empty the condenser drawer. What I didn’t realise was this completely bypassed the condenser cleaning. After 3 years my wife said the tumble dryer is taking forever and our electricity bill was higher than usual. Being around Xmas time she was looking at a new one. At the prospect of dropping a grand on a new machine I decided to take a look. Low and behold the condenser was full of lint, and your tutorial helped me through the solution. Now the tumble dryer is good as new! I would sincerely like to drop a few quid your way to thank you.

[@askmrwashywashy]

So glad to hear you were able to fix it and it’s back working again Good on you for taking such an extensive repair

[@u1zha]

I'm facing a similar issue, absurdly fouled up condenser. Is it true that the drain setup bypasses the self-cleaning? Says nothing about it in the manual afaict. Are they nuts??

[@WardvanKoperen]

@@u1zha I have the same machine but then from Siemens, I have it connected to the drain. There is a valve in the system which selects every dry cycle to not pump to the drain but pump to the top reservoir. Then this water is then used to flush the condensor.

I would have never been able to revise our dryer without this video. Thanks!! You saved me a lot of money on a new dryer.

It's working back as new!

You sir are an absolute legend. Saved me calling out someone to fix. These car dashboard removal tools were great for removing the clips. Glad I watched all of the video before starting. Removing the heat sensor before trying to remove the harder to reach screws made it much easier. I could just use a straight driver. Thanks again.

[@lars-erikbtkerpetersen9466]

Exact my thoughts about the sensor and plastic shield. I'll also go cheaning ALL the support wheels for the drum, and add a bit lune before reassembly. Also a bit lune or copper grease for the main bearing. And thoroughly wacuum clean, plus use a soft aircompressor for the condensers.... Think it is worth is as it already IS taken apart. - 😇 Great video although the volume was very low... 👂🙉🎧 Thank you so much Mr. Washy Washy - 💪🤗🙏

Thank you for a truly detailed teardown and clean out video. Would agree with the other comments, do not use a cloth on the condenser, vacuum with a narrow tube and soft brush end. Fixed my Series 6.

It has been already 5 years since I have bought mine. I started to wonder does the "self cleansing condenser" need servicing and I got to your tutorial.

Welcome glad you found it and it will be handy one day

[@plusminus4883]

However - got really surprised, when I looked through the front grill. It is clean like brand new. Nothing covers the parts inside. Similar can be seen in the cooler compartment. Looks to me that the cleaning will have to wait a while. Could it be because we follow instructions to wash the filters every time after run?

[@chloe161088]

Thanks so much for this, what a great video. Easy to follow and really detailed. Our dryer started taking a really long time, it's 3 years old but has had heavy use. It lives inside a laundry cupboard, which is fine according to Bosch's website. The amount of lint in here was perplexing - I clean the filter after every use and always have done. What a huge fire hazard - I'm going to call Bosch and ask if I've been doing something wrong for it to get so built up. We can't thank you enough for the upload! Have a wonderful Christmas.

Wasn't looking forward to it but I managed to clean my "not-so-self cleaning" dryer thanks to your instructions. Took me about 4 hrs to dismantle, clean and reassemble. Great help. Thanks! 👍🏻

[@exNRGista2]

I'm currently cleaning the second machine in my career as an appliance repairman. It's a 2010 EcoLogixx 7 WTW86561IT/03, built on the older platform as the first I did, a 2013 one. Each time I do this job I actually disassemble the whole machine, even lifting up the entire heat pump assembly and pulling it out of the basement, operation that has to be performed slowly and gently. I'm helped by other two people: one holds the compressor, one the condenser (the hot side, in the back) and one the evaporator (the cold side in the front, referred as condenser because it collects the moisture). Then I blow and wash every single non electric bit, especially the basement which is always full of crap and the evaporator. Finally I reassemble the whole machine, replacing belts, rollers or felt seals if needed. But generally most of the time I find them in good shape, in the first machine I cleaned I've only replaced the drum belt and the second I'm actually doing has surprisingly everything OK. If it was an Indesit, it would be all worn out 🤣 There's still some typical German quality in these machines and they do worth the effort to extend their life, especially on the older ones. The only shortcoming IMHO is they don't reverse the drum rotation, otherwise they are very valid machines!

[@claudioborzillo6933]

Champion!! Got it apart all the way as described on video and back together with all screws in place👍 Thank you for putting this video together and posting it!

[@askmrwashywashy]

Welcome glad it helped

[@rudiselectronicslab861]

Also I performed this cleaning procedure, on a Siemens iQ800 WT47Y700NL. It has some slight design differences (there are two back plates, one metal and one plastic, and there is no additional wheel for the belt - just the motor axis and the drum). But the cleaning job is just the same. The machine was generally fairly clean inside. But in the end, there was a thin but impermeable layer of dirt blocking the condenser. Cleaned that and the machine runs as new! Thanks so much for doing the effort to post this, Me. Washy Washy! PS. By the way, the WT47Y700NL (and possibly others) does have a COMPONENT TEST MODE. It can be accessed by (1) switching on (2) setting the rotary knob to "towels" (3) pressing the "dryness level" button AND KEEP HOLDING IT (4) turning the rotary knob to "Blanket", (5 ) Release the “dryness level” button (5) Briefly press the “dryness level” button again. A menu will then appear with all kinds of measured values (sensors) and you can walk through eight options. P1 (motor, fan, P2 (compressor), P3 (rinsing), P4 (cond.sense), P5 (ref.pump), P6 (refresher), P7 (drain set), P8 OU test. Each option is with the At P1, for example, you switch the drum motor on and off manually, and at P8 the device tests all lights and the display.

[@askmrwashywashy]

Wow so glad you fixed it. Thank you so much for that handy tip for test mode. Much needed and will use it in future videos

Thank you very much for this disassembly video. Had the same problem and now the radiator in my drier is is clean (again).

[@indorock]

Thank you so much for making this, it was incredibly helpful. Without it I would have called in a professional and be a few hundred euros poorer at this point. My dryer was at least as lint-filled as yours, probably even worse. I just put everything back together this morning, and it's humming smoothly again and drying clothes as it should. As a note: our dryer is about 8 years old, and we always did maintain the good discipline of cleaning out the lint tray at the end of every cycle. So it's not a lack of care that is to blame, but probably poor design. From what I can surmise, the felt seals between the drum and the dryer frame are far from perfect and they allow lint to pass this barrier as the drum spins. This is the only way I can imagine the lint to end up everywhere like this. Bosch needs to improve this seal or add a secondary one.

[@askmrwashywashy]

Welcome glad you were able to fix it. It’s poor design indeed. Hopefully the future models have better filtering/catching of lint

[@invisibblle]

I don't think that bosch will improve the design. Probably they are designed like that. @@askmrwashywashy

Big thank you! Our 8 year old Series 4 weren’t really drying anything anymore and clothes smelled funky once dry. Figured that heat exchanger needed a clean. Never really trusted that ”self-cleaning” function. There were some lint, nowhere near as much as the one in the video. Which was a bit surprising given the age. I guess we’ve been cleaning the filters properly. However, the HE. Oh boy! It was a thick thick layer covering both the small and the large one. 😂 Ended up removing the front. Not sure I saved any time, but I didn’t like the bending parts. Also, some commented about getting a proper seal again. Took me a total of 5 hrs. But only cause I had to go back and redo some parts. Cheers!

Now it works perfectly again.

[@MrJ8m]

Did you have to replace the pump or just clean everything out?

[@timusius]

@@MrJ8m Just below the pump there are two sensor "sticks" going down into the water in the bottom of the machine. They were coated in old textile fibers so they made a constant connection with the water. So the machine thought that it could not empty the water out. (It works in a somewhat backwards way. When the lower container is full it tries to empty it using the pump. If the pump runs for long, the machine concludes that the upper removable container is full.) It was enough for me to clean the machine. ( I manually flushed a bunch of water through the lower part, and emptied the pump chamber many times until the water started to stay clear.) I might even have been able to clean those sticks without taking it fully apart, since there is sort of an opening just above them, but I did not know that at the time.

[@timthorn6237]

This is a fantastic video, thankyou!! But it is worth noting that the later revisions of this model don't have an issue with the self-cleaning condenser clogging like you see in this video - because they added a secondary (very fine) lint filter to prevent the condenser and evaporator clogging. I did the full teardown of my dryer per this video (which was not drying properly) to find the condenser and evaporator perfectly clean. The problem in later revisions of this dryer is actually the fine lint filter they introduced to fix the earlier issue. It can visually appear perfectly clean and free of lint, but try blowing through it or running water through the filter. It's probably partially or completely blocked. Scrub it, vaccum it, and keep doing that until you can blow air unobstructed through all four of the lint filter panels. Replace the filter and your wet clothes and stupidly long drying times will be fixed.

Another observation; detaching the humidity sensor (two screws just above your left hand at 20:29) helps acessing the screws you are about to remove at that same time.

welcome im glad it helped. fingers crossed you've fixed it

[@Timmie44]

Thanks! What a perfectly detailed video. This helped me a lot. Took me 4 to 5 hours, but decreased the drying time significantly.

[@askmrwashywashy]

Awesome glad you were able to fix it

[@theC4CH3]

Thank you for all detailed disassembly, cleaning tips, extra reassembly technique. This is my favourite repair guide so far! Sadly the construction is complicated as hell. I hope my machine not like this. Cheers!

[@askmrwashywashy]

Welcome. Hope it helps you if you ever do need to fix yours. The trick is to do it I’ve a couple of days and not try to do it in a day

This is an upcoming task for me. Our dryer is now 9 years, so it's about time! I think I will add a step: dismount the refrigeration cycle (compressor, condensor, evaporator etc). This way, I think I can clean the coils alot better with air and water + a detergent. I might also be able to clean the underlying plastics. Not sure the plastics will matter, but cleaning the coils more extensively is not a huge added task compared to the overall project. Great video!

Thanks for your help, my Dryer is all clean again and goes fine now.

Great video, very helpful! I have a Bosch Series 4 (WTH85200AU) and the steps are very similar - up until the cover on the condenser. There is no separate plastic part to unscrew and the clips on two sides are as shown - but after that I couldn't figure out how to take it fully off. Thankfully from what I could see it wasn't very dusty (in contrast to the rest of the insides!) After cleaning out all the lint (worse than shown - this is after 4 years of almost daily use) and putting it back together, it is actually drying properly again! Thanks so much!

[@cheyennenicasia3178]

Thank you very much for the good explanation and keep up the good work. Our dryer is as new again!

thanks so much for sharing this detailed procedure! Have a good life.

[@VisualPrecisionLtd]

A good video up to a point. The biggest issue is you snapped the retained tabs off when removing the top of the condenser box. This means that the lip won't be held on properly causing hot and cold air leakage. You also didn't explain that there's a gasket that has to be seated carefully when replacing the consder box lid. The only way to successfully locate this and therefore get an air seal, is to remove the cover at the bottom of the front panel and loosen the screws that holds the front assembly in place. When this has been done, the gasket can be reseated. Other than that, a very good video. I fully dismantled my dryer and rebuilt it on the back of the video, so many thanks.

[@askmrwashywashy]

Glad you were able to use this. Will consider it in future videos to include that info. Sometimes it’s so long doing this procedure I forgot some bits

[@etherhuman]

Thanks, this comment really helped to figure out how to put back the condenser box properly which is a crucial step. The comment really should be pinned so that others don't break something trying the method shown in the video. Taking the front of also makes cleaning the front of the condenser much easier. Another note, it is tricky to open the front bottom panel without breaking the tabs holding it together. There are tabs behind the panel that need to be pushed with something like a screwdriver to release them.

Thanks so much for uploading this mate! Perfect timing coming into some wet weather. Saved some coin too. Legend!

Welcome mate glad it helped

[@raftonpounder6696]

Great job. I was wondering why our dryer wasn’t heating very well. I already had to pull the motor out and stick one of the magnets back on so I may just prepare myself for a more complex strip down. Thank you.

[@Itslvle]

Thank you, helped when we had to take apart ours as it started to smell and there was no way of getting to the heart of the problem without disassembly.

Great vid, worked like a charm, thanks!

[@alicewilson5166]

Fantastic thanks, really helpful. Managed with the help of your video to take our tumble dryer apart, clean it and get it working again. We had a problem with the condensate sensor under the pump which also had to be cleaned along with the sump to prevent incorrect condensate reservoir full errors.

[@askmrwashywashy]

welcome im glad you were able to fix it.

[@DavidBridgeTechnology]

Was considering a heat pump dryer. Now not so sure I want one. Great instructional video for anyone who already has this but also a good warning to people like my considering this to replace a vented dryer, believign them to be safer as well as cheaper. At least the vented dryer expels most of the lint. (BTW: Maybe consider buying a new microphone. It's a bit weak.) Thanks 😀

[@askmrwashywashy]

Hi thanks for tip. Will fix up the audio in post.

[@martienswart196]

Mr Washy Washy, thank you very much for you very detailed instructions! With your video I repaired my 9 years old Bosch WTY87700NL heatpump dryer with the same amount of lint as yours. Just tell me how I can buy you a beer.

[@manicstream4844]

Just attempted this today on my Bosch series 8 dryer. It was such a fantasitc and easy to follow tutorial! Took a few hours, the lint that came out filled the vac twice! The baked on lint on the side of the condenser had to be wet down and gently scrubbed of with a tooth brush. It's all back working perfectly now. Many thanks to you.

[@BAD480MAN]

Thanks a lot for this video, now my dryer runs like it’s new. I also removed the complete heat pump assembly, just 3 screws on the base of the pump, you just need some help to carefully lift it out, then I used air pressure to clean the condenser and heater. I can really recommend others to do this as it also makes it possible to clean the disgusting water tray underneath the condenser.

[@forfengeligfaen]

How did you disconnect the compressor electrics?

[@russellthomas3999]

We bought our Bosch heat pump in 2016 and we use it nearly every day. Recently it hasnt been drying properly and found this video. I did go one step further than this video in that i removed the compressor (3 screws, earth connector, senseor connector amd 3 pin plug at top. And lifted it out to clean it. Under where the condensor sits there is another removable tray and underneath that wad all clogged up as well.

[@TangoMikeyB]

This is a great video. However, I fixed mine without pulling it all apart. I did a couple of things, and I'm not sure which was more important. Perhaps also relevant is that mine is plumbed in so that it automatically empties. First, without dismantling anything I poured water into both the filter slot (with the filters removed) and the flush hole underneath the water collection drawer, near the front if the drawer is removed., About 4-6 litres each time. Then I ran the dryer on a timed cycle for 20 minutes each time and at the end of it emptied out the water collection drawer. I did that a few times until the remaining water was clear, in the early cycles the water was obviously cloudy from lint fragments collected from the condenser, but after a few (6-8 times, can't remember how many exactly) it was quite clear. Second, following the video I pulled the right-hand side panel off (looking from the front) and vacuumed as much of the lint as I could get to from around the heat exchanger pump and pipework and anything else I could get to. And, like in the video, there was a lot of it. Since then it's been as good as new and dries stuff in the indicated time or less. Before I fixed it it was taking hours, often 4-6 hours to do a load of towels, and since the fix it's never taken more than three. I suspect the main thing was cleaning the condenser vents by flushing them with loads of water. One time I put 8 litres in at once but I think that was too much, water ended up in the drum, but it seemed to sort itself out in the end, and next time I do it I'll stick to at most six. However it might also have been to do with clearing the lint around the compressor, I suspect there are temperature probes in there that are important and if they are insulated with fluff they're likely to feed back wrong readings. Dunno, but since it's been done it's been within the indicated times and also it seems to get hotter as it's drying too. Usual disclaimers: Don't blame me if you break yours doing this 😂

[@markb3787]

Wow that’s more intense than the Bosch washing machine repairs that I’ve done But I’m going to give it a go My Bosch dryer has this exact issue It’s a crazy design that seems deliberate so it can’t be serviced Call me normal if you must but normal folks don’t clean the lint filter after each load It’s hard enough to simply get the other people who live here to even turn it on 😊
