Your explanation + schematics is what made your teardown videos much better than most others.
This is our second K-Classic. We had our first one for many years, so when we had to replace it, we wanted nothing else but this exact ua-cam.com/users/postUgkxBrV-RbF5Nk0Rlt9i15aao-YMzqzTG8Vf model. We use it for about three people everyday in the morning. The taste and quick brew is one of the reasons we like it so much. There are so many choices of brands of coffee that we would grab what was on sale and test the different brands from there. I would definitely recommend trying different brands of coffee to find the ones you like the most because there are brands that quite frankly taste horrible.

EVEN MORE SAAAALT INTENSIFIES
Newer version of this coffee maker that i own includes a special needle that you can put in the clogged needle to unclog it ;)
But what if unclogging needle will clog? (Sorry for bad english)
Hello uploader. Ive had allmoust the same type of coffee maker. Mine was whit electronic display. And...the same problem. I solved 2 years ago ,and give it to my sister. Still works in our days. Good luck forward.
I love studying electronics just because of you ;) thx a lot.
Wow!! I enjoyed so much especially your great Czech accent!!! I remembered when I was living in prague! Thanks
I love Czech people and country
You underestimate the cleverness of printer manufacturer. The cartridges of the printer you buy don't have the amount of ink as the ones you buy separate.
Even better is a leading manufacturer which name I won't name for legal reasons. But their logo has a H and a P in it. Offers a subscription service where they send you Ink if it runs low. The cartridges the use for this purpose are circa twice the size and quadruple the weight of the once you can buy.
Glad I'm not the only one who feels sleepy after coffee, it seems to make most people more miserable too even if they think it's helping.
That's strange
Well actually it really works for most people. You just need to know the chemistry, but everybodys body reacts differently. Some people will fall asleep and for some people it is just normal drink that does not do anything with them. :D
That needle gets cloged pretty easily. I had simmilar type (with slightly more practical shape) and i was cleaning it up quite often. I was also fixing the sealing from water tank and then happily get rid of it :)
BTW your videos are awsome and you are doing a pretty good job with the schematics! 👍
It was so satisfying to watch you opening it apart. What a complicated machine just for making coffee..
You should have started by checking the final output choked outlet nozzle.
The 🐈 so innocently sits and watching the machine.
I LOVE your reviews, and of course your cat. Thank you for your very informative, and educational reviews!!!!!!
Iam going to say this with much love, because you are tremendously smart with electrical components and schematics, but that would have been the frist thing I check. But really do appreciate the break down of the components.
best thing about this video is the cat at the beginning, bless her/his soul
You didn't had to cover your reflection. People who watched you in Czech republic as Danyk666 know you
Majklova bastlírna Don't worry. He can look like gray square irl who knows ??
Also there are photos of him on his site danyk.cz/ja_en.html
dama 43 This website doesnt work

R V Thanks
The coffeeeeeeeee I love how he speaks and love the Chanel
The BT137 800 is a very very common triac ... the bt137 600 is mostly found on those ebay blue handle solder irons with adjustable power ... they are named solder irons with adjustable temperature ..but it is just adjustable power solder irons.
The coffee maker is a very well known model all over Europe and from a very known brand :)
Your cat is very cool also.
Hell, I remember that these dispensers were available in my country, but it was probably long gone
You can take hairspray and spray it on chrome surfaces from maybe half a meter of distance to diffuse the reflections. Let it dry for a bit, it won't be tacky. Later it can be washed off with a rag with a bit of warm soapy water.
Thanks, that's a useful idea :).
Or just show yor face. Noone will kill you for that :D
Just cover with masking Tape will do the job..!
We really already know what DiodeGoneWild's face looks like from elsewhere >.>
Tape. Tape. Of course tape. I feel so stupid.
But he can't see with masking tape covering his face!
I have a Dolce Gusto mini, always wondered what was inside :) I had to repair the water tank with clotch tape for repairing glass windows on greenhouses. A new one is too expensive lol. They do cheaper Kenco and Aldi knock off compatible pods in the UK which I buy, but I sometimes get offers from NesCafe to get discounts ordering online. I won't pay more than £3.50 per box as they are a rip off lol You can get cold drink pods like Peach Tea, Lemon Tea and some other nice cold drink pods ;) Your always welcom to come round for a Tea if you prefer, but I do drink coffee but it keeps me awake lol not sleepy :), oh and bring your cat, I love it, I could stroke her all day :)
When the pin enters the pod, the clamp down creates a seal. The water pressure forces the water out the bottom, you can hear it pop when this happens. Inside is a small silver foil over little spikes in the plastic at the bottom and a plastic seal over the coffee under the label. The pods are self filtering.
As a first guess before watching the whole video is the pin is blocked by scale, there should be a small circular pin prodder behind the water tank you remove to unblock the water pin :)
Dolce gusto is an italian coffe machine, and it's not too bad
I have owned two K....g coffee makers, same idea as the one in this video, different shape. My first unit stopped pumping after three months so I called their tech support. Their entire troubleshooting procedure over the phone was to have the customer unplug the needle with a paperclip. I knew that wouldn't work because at the time I only made hot water for tea with my unit (didn't like the cost of the pre-packaged coffee cups which also tended to be stale from the stores in my area) but I let her follow her flowchart anyway. After several tries she finally agreed to send me a new unit. While I waited for it to arrive I took the broken one apart, found the hose that had pulled off the top of the tank, put it back on and the thing has worked fine since. The new one also had a problem which I'm sure would have not been repairable per their procedures. However, to save them the cost of replacing it (and my trying to convince them that I actually had two defective units) I took it apart, found the one-way valve inside the end of one of the tubes that had glued itself shut, gently pried it open with a small screwdriver (the valve probably became stuck due to some residue left over from its manufacture) and that machine, too, has been working fine since. BTW, K used to sell a filter cup and holder assembly into which you can put your own coffee grounds. You simply use it like a normal disposable cup and clean it out after each use. Mine has lasted five years and shows no sign of wear. Saves lots of money and tastes better because you can use coffee that you know is fresh.
love you vids keep it up bro
The heating element is inside that metal can thing. I took apart a Keurig version of one of these. Got a bunch of nice parts. A small air compressor and a very nice pump. There was an LCD screen but it was all white when you plugged in the machine which was the reason I got it to tear down.
some electronics nerds indeed have a rather peculiar accent, black sheep logic, dave jones (locker?), etc. just to name a few.
Love them and their videos though, I learn a lot from them.
LOL ;-) This is perfect Czech humour. Love it! You took the whole thing apart to clean the needle ;-) However, I've learnt how to replace the needle. It was very useful. Thank you ;-)
He is a complete idiot, nothing funny there.
You should have pointed out that every dolce gusto has a cleaning needle included. Yours is behind the water tank, left bottom. That round springy like thing is a cleaning needle ;)
Thanks for making this. There is a product to use once a month if you have hard water to descale the inside surfaces of the coffee maker. You can use it but of course less fun than a teardown.
Zavápněná tryska z tvrdé vody. Nejčastější závada všech kávovarů :D
I like seeing teardowns of things and repair and how they work
There is less in there than i expected, i first thought the bt151 was chopping the voltage to the heater to change the heat, but then you showed the valve mixer.
Odd how that tube got clogged.
Oh hiding behind grey squares don't stop us knowing that you like wearing a gingham dress he he :-D
Now I dont need to overhaul everything! Thanks!
Very enjoyable, brightened my day up!
I own one of these machines and have researched the working mechanism profoundly, both the machine and the capsules. I don't know why but I found extremely funny how he was so clueless about how the capsules worked. Also he didn't know a thing about the machine, but it's something to expect if you don't drink coffee at all. I feel kinda bad seeing this poor machine completely destroyed, but at least I learnt how mine works. Also is pretty funny that all the fault was a clogged needle. Those machines are pretty durable if you treat them right.
The *C* Off *EEEEEEEE* I love how he speaks and love the Chanel
When you showed the needle, it looked blocked. I have on of these at home and you need to clean the stuff that builds up over use.
Great video mate, thsts so fiddly to take apart! you have got more patience than me I would have thrown that up the garden after about 2 minutes!
I saw your face in the reflection! It's beautiful brother
Which magic circuit do you use to convert power usage to DC voltage on your custom power cord? I like it!
What! “No fire extinguisher” you just broke all you’re health and safety rules.
Why a fire extinguisher? Isn't it leaking enough water all over the place? :D
Next video request "Face Reveal of Legend DiodeGoneCat"
WOW. SImple fix. Very interesting teardown. THANX.
Maybe the coffee pod bottom opens under pressure from the water?
Or maybe it melts... who knows... but the cartridge probably can't be pressurized much, it would leak around the needle.
You are right Stuart. Here is a cut of capsule. You can see that on the bottom is a thin foil which is pierced by field of plastic spikes on the bottom when top of capsule get under pressure. That is the reason why you shouldn't use capsule once used. ;)
commons.m.wikimedia.org/wiki/File:Dolcegusto_capsule_w_annotations.jpg
Cartridge teardown is in order, I think. I was thinking melting or dissolving like medicine capsules.
seems like the bottom just contains some plastic mesh, and the coffee inside maybe is so compressed, that it doesn't let air trough yet, when you press the bulged top.
Cheese 1337 I was curious, so I opened one and there is thin film which is pushed by pressure of injected water to small spikes. What make way for water.

Can you do a reverse engineering of your old switching+linear power supply that you have in old stuff ? I found it really interesting how it adjusts the minimal voltage drop across linear regulator .
Simple operating instructions: Make sure lever is in middle, lift flap, pull tray, insert pod, insert tray, lower flap, press the power button.. now the trick is to wait for the ringlight to go green before choosing hot or cold water, job done. 😊
glad to see that im not the only one that chews the hell out of things while disassembling things lol
Just descale this coffee machine with acid solution, check for any leaks and it should work fine. I think I can see metal pin for cleaning that needle hole at the back of this machine. Put your finger on that ring and pull it out. You can also get refillable silicone or metal capsules online. Parts for repair also available but sometimes it's not worth to do that. Better thing to do is to buy semi automatic machine with steam wand and seperate coffee burr grinder manual or electric. It's more reliable with only two thermostats for water and steam and you can make a lot of coffee drinks.
Thank you sooooooo much brother 🌹🌹🌹❤️❤️❤️
Covering up your face while you showed yourself in your old videos on your other channel :D
Big thank´s now i maybe can easy repair two of my coffie mashine i have three and i maybe i will look on the working becuse i think it soon stop in that also, good video you explain so mutch, like your videos.
I love your videos keep making them you deserve more subscribers!
Ben Logic Agree. He deserves it !
nice censering
you could probably bypass all the electronics with 3 position switch
Im not laughing, personally i think u are amazing. Like your videos!
I have one of these. The pod opens under pressure but if there is no water coming out then maybe the water injection nozzle (which penetrates the pod) is blocked. It can become blocked with limescale. I unblocked it with a needle.
I LOVE YOU man. Keep going.
Thanks for this very useful video, although I did not take our machine that much apart to make it work again👍🏻
probably one of your funniest vid ever hahaha.. i know it was perhaps not meant to be funny but still.. btw the hole on the underside of the cups is probably sum kind of plastic pressure seal..
because the machine produces pressure something like 15bar to push out the coffee . i got my wife the mini.. she love to drink hot coco and for the ease of use the price of the cups is ok.. you can aslo grab third party cups that cost way less.. for my day to day coffe i use a moccamaster that has a cooper heating element and a nice expensive coffee bean grinder same brand..can't start my day without a good cup of coffee my friend.. it's legal drugs hahahah
The top of the cartridge is like an aluminium foil. At 15 bar it would be long burst :). And it would leak around the needle anyway. How the bottom gets opened is still a mystery to me :).
so you think Dolce gusto is lying about these machines producing coffe at 15bar ?? that's one of their main selling points if you go on their site click machines and look at the specs and sum talking points they are pretty proud it produces 15bar.. reall espresso folks will tell you their machines produces something like 9bar ..that's why the folks from Dolce gusto like to advertise their 15bar.. but of course the pressure doesn't make the coffee taste better more things come in to play..
Nespresso page says "up to 19 bars". Some other sources for other machines claim "2 bar" or "4-6 bar". Which (UK) says "3.3 bar" for the Tassimo machine.
Bottom being opened by pressure appears to be a common theme.
Does the top of the capsule get pressed against the rubber seal, especially at the border? If the mounting pressure is sufficient, it would solve the issue. The structural integrity of the cup is then maintained not by the cup itself, but by the supporting structure, and the bottom can pop open.
In fact there's a possibility that the capsule sits loose in the holder, however with pressure being applied to the cavity, the capsule expands and seals against the surrounding structure.
nice explanation.. today i descaled my wife's gusto mini machine..i myself don't drink that crap.. 100yr old coffee without a burn date.. i use a nice drip machine with freshly roasted beans.. roast date no longer then 1.5 months ..and ground on the spot.. DiodeGoneWild will probably think i'm mad all that fuss about coffee..ahhaha
I enjoy your humor. Please let Americans in on the humor of your world. We are so isolated by our media czars that we only see what they want.
The way how he talks makes me laugh !! Lmfao!!🤣😂😂😂😂😂🤣🤣😂😂😅😅😂😂🤣😂😀😅😅 ( But I’m not making fun of him)
he is a legend...at speaking in English
He talks like chills lol
He is unique 👍
In the down right of the scheme is not probably 0v but at least 5v, (i mean the DC logic output) but thank you anyway....see if i'm able to fix mine!
Where do you get replacement parts? Thx
With Dolce Gusto, you press button and wait for a minute or minute and a half until it heats up the water, once it turns green then you can use it, by pushing lever to red, I have one myself and I am a coffee drinker
coffee catridge is made from top cover foil that is punctured by needle and 2 cm lower second plastic foil with small holes it keeps coffee in place-below that is coffee, below coffee is lower plastic foil that is seal and it is completely closed before using capsule, same as top cover seal. below lower seal is sharp strainer/filter, and last part is capsules hole, it works like this: needle makes hole on top seal and it is pressed and sealed from coffee machine rubber pilow that is pressed down when lever is down, hot water enters into capsule, and passes through, coffee , pressure raises in capsule and coffee and water brakes lower seal on plastic strainer/filter that has sharp tops , and coffe comes out of capsule,
How can you modify it to make the coffee hotter? Everytime I use a coffee machine like this, the coffee always seem warm and not hot
Excellent reverse engineering, we have some strange metallic disk shaped objects in Antarctica we would like you investigate. However you can't show it on UA-cam...
that's very interesting. I've had the square Krups dolce gusto in red for many years and got the exact same one in black for free with my news paper subscription... after not using it for a year, it did the exact same thing. I really wanted a second one for in the office because I really like them, you can make both cold and hot beverages (there's different pads / cartridges). I get the off-brand ones at the store and they're about €2,30 for 16 pods, which is very decent and about twice as cheap as the real ones. I ended up just buying a new machine (Amazon temporarily had Delonghi machines for only €25!!, usually they're only Krups in Europe). after your video, I'm just gonna poke a needle through the dispenser/needle... I might end up with 3 dolce gustos...
I also get really sleepy after drinking coffee! it's currently 00:17 and I just drank one, so... goodnight 😂 .. they make good hot chocolate and tea as well, though.
Usually if you get sleepy after coffee then you are overtired.
@@LimbaZero I think it's because of the heat, but it's a known fact caffeine has different impacts on different people. If I force myself to stay awake after drinking coffee, I won't be able to fall asleep for another few hours.
For example I drink coffee at 23:00 and fall asleep by 23:30. But if I stay awake until 0:00, I'll find myself doing something random at 2:00 because I can't sleep.
thanks for this video , can you make a video about phase angle control for triac and these quadrant thing
The capsule sensor is a reed switch. There is a magnet embedded in the rear of the holder. I fixed one of those once, it was the reed switch that wasn't working. :)
Thanks for this knowledge :). So many details I didn't examine, and the video is already over 30 minutes long :D
You are supposed to turn it on and wait for the led to turn green before you turn the valve. 😂
Yeah, something like "Windows 95 is booting...", only there to be there, not neccessary but looks more technical.
Why this channel is so good ?!!! :D
Ahmed Dagher how he talks
Poor man, you can't drink coffee :o
Very like your video, I also open every device to see what is inside :-) This learn...
Very very nice video, i have a question, can you make a video teaching us how to make schematics from any board?
You can buy "star with pin in the middle" shaped from Bosch to use with your Makita
Good job
1:18 yeah man...
So we drink coffee to stay awake 😎
The bottom of the cup has a coffee filter in it, blocks coffee grinds only liquids to escape.
Thanks God... You are back.. 😍😍
Sorry for the delay :). Tomorrow I probably publish one more video :).
DiodeGoneWild I'm feeling lucky you replied. 😇😇
Yes please post video regularly.. I love your videos.... Always find something educational 👌👌❤️❤️❤️
6:10 when the water gets inside it opens the special valve wich opens only when there is water inside(this is why it's so expensive) :)
Excellent video thank you
Muchas gracias, expectacular su explicación. Saludos
Very funny how you tried to hide the name of the machine at one point, whilst you showed many times the bottom reading KRUPS!!!!! lol
Big thanks, nice video !
very smart man !!!!!!!!!!!!!!!
Now that you finished it you can have a coffee and go for a well deserved nap.
Actually there's a tool under the tray for that reason, i have the dolce gusto krups lumio and it has clogged only once, i found the tool by mistake and curiosity. It's a very common problem for the needle to get clogged
Nice diagnosis of the blocked needle using the syringe of water connected to the tubing. The excess of plastic parts in the design seems a little overcomplicated.
You could do a teardown on the capsule itself. I guess it is filled with a noble gas to keep oxygen in the air reacting with the coffee, and the bottom seal is held on by the pressure. If the top of the capsule is punctured by the machine, it releases the pressure, that releases the seal and lets water flow through it.
Another comment already answered this. See commons.m.wikimedia.org/wiki/File:Dolcegusto_capsule_w_annotations.jpg for a sliced capsule.
I've since taken one apart myself, and it was more or less, like my assumption. Pretty clever construction that keeps your coffee fresh until you use it.
You shouldn't reuse the capsule once punctured. It opens under pressure. The needle tends to clog a lot. Especially in areas with 'hard water'... so its best to often run a cleaning solution through the device.
DGW great work man, thanks for sharing :)
Coffee makes you sleep
Get it
Now that was funny.... thanks DGW!
i have one of those to repair sometimes the power button doesnt work any ideia i replaced the button but it did not solve the problem
Ball valve, water comes in,, it floats then the water can go through and then where there is no water it goes back and seats, also there is an in built filter
0:50 As a coffee lover, let me tell you that the powdered stuff tastes like dust. You don't need a big machine to make coffee, but you do need a big machine to make good coffee.
17:48 HAHA I GOT YA FACE jk but there you go my friends
Love your videos 👍👍👍
Hey bro, I missed you. It's been a long time!
Useful video
So basicly.. If youd just take the metal wire from the back of the water tank you'd have fixed the issue in seconds. Its there for a reason, the needles get clogged pretty easily.
Ta mačka je nádherná
Viac takychto videi :) Pozdrav zo Slovenska.
Díky :) nějaký ještě určitě budou ;)
Great~! Really interesting.
