Dropping the board and shorting it out , we all did that in one way or another (or something very similar). Thumbs up 👍
specially right over a metal object. That's why I always have a sec camera recording my bench, never miss a moment like this if it ever happen.
Or shorting the board with probe 😅
@@MegaFoster86 Yes, the old classic!
@@MegaFoster86 slipping and almost kill the oszi
When I was troubleshooting a hard drive measuring voltages on the board the internal resistance of the multimeter was enough to trigger a reaction in the motor driver chip and it exploded
Glad you decided to publish this video as it shows the damage that can be caused to chips. Then very interesting to see how you used donor parts to rescue a device otherwise destined to contribute to landfill. Extra bonus is the two appearances of the cat. 💯
You seem to have spares for every repair you do so even mishaps such as having the circuit board drop into the chassis can be repaired. Very informational and entertaining (especially your "catty comments" ) bring a special warmth to your videos. I especially enjoy your home-made testing equipment.
It should mix the ingredients first, then iit should pulse the heater to get the yeast active and let the dough rise, should pause and do nothing for 20 or so mins when it does this. Then it should do a small pulsed mix to knock down the dough after it rises, then start baking. Thats kind of how mine does it. The programs on the panel can shift between different types of baking/kneading cycles depending on what type of bread/pizza base you are trying to make. The beeping might be for some breadmakers that will pause and let you know to add more ingreadients at the right time of the kneading cycle for making things like rasin bread or grain bread etc as they have to go in after the yeast has made the dough rise. Ive had a couple of different breadmakers over the decades and they all kind of do it a little differently but the method stays the same. Mix thoroughly, let yeast rise the dough, knock down dough, bake then done.
or to summarize, next time RTFM ;-)
One of the things I learned (the hard way) with these machines, is that the preset dough rise times are too short - to get a proper bread, you need to make an interrupted cycle, and control yourself the dough rise time, and only then proceed to baking.
I appreciate the effort you went to to repair something most people would have just tossed and replaced.
We have a Japanese bread maker (Zojirushi) with an identical internal layout. I've had it apart to clean and re-lubricate the sleeve bearings after about 20 years of intermittent use. It was interesting to see this same design pattern in a different machine.
Yes, I was also surprised that almost all bread makers from all brands use the same internals. I saw several videos of people disassembling them and the motor, the gears and the control board were probably all made by the same company. Disappointing. I had a naive belief that Eta was made here in the Czech Republic.
@@DiodeGoneWild Eta is now owned by HP Tronic, a Czech company with headquarters in Zlín, I believe. Alongside with milion other "private brands" (Goddess, for example) , they use it to brand many Chinese OEMs...
So in a way, it still is a Czech brand, but it has none of its former famous R&D done here anymore, I'm afraid.
Similar to the Ford EcoBoom engine timing belt - disaster.
No way Zojirushi is using some no-name chinese crap
@@paul_ko possible that Eta is outsourcing to Zojirushi, or licensing a Zojirushi design. Especially if they want to maintain their reputation as a high quality Czech/European brand it would make sense to use high quality designs rather than cheap crappy ones. Also the housing looks very similar to my Zojirushi rice cooker
My guess on the motor:
They used aluminum for the windings in the newer version and added the fan to compensate for the higher losses. So they cheaped out by adding the fan, not the other way around
I like that guess! As reveales by Danyk, copper cladded aluminium wire is very common all over Chinese electronics..
I'd love to see you making bread with this in the next video!
Maybe ring-testing motors without rotors shows some more rings?
Well, maybe :) but still, even iron transformers are not really suitable for ring testing. Removing the rotor would probably make it act similar to an iron transformer. The iron core is lossy, especially at a higher frequency. A higher ring test capacitance also won't help. It makes the frequency lower, but also gives it more time in each cycle to dissipate the energy in the winding resistance.
Those original belts look like Kevlar reinforced ones specifically meant for high temperature environments.
Hopefully your new belts will be ok in the hot environment.
Another great video, thanks for sharing & taking the trouble to make it for us.
Thanks for posting it, even with the mistake made. Your persistence is amazing.
That's an interesting way to de-cap the microcontroller 🙂
Now we need a DGW-style bread baking video! Could be just a Short because it's off topic, but I'd still watch
Maybe on Danyk's 2nd channel? 😅
Finally I can look at repairing my mothers bread making contraption now I know what to look for! I am sure you are able to read minds LOL I say because before I watched all the video I was thinking 'I wonder if he ever breaks anything he tries to repair' You did not disappoint! For that I thank you kind sir :D
Prosím, could you do me a favour? Could you give your beautiful cat a big hug and kiss from me? Děkuji
My Father had a slightly simpler bread maker 20 years ago, the heater relay got stuck on and it charred the bread into a small block of carbon carbon and put 6 inches of smoke on the ceiling. That bread maker had a small fan with it's own motor, which might explain why NO thermal fuse tripped, it just kept going! It didn't catch fire however.
Great video, as usual. I think this is the first time you had to order parts to fix something ;)
3:20 Fully agree. I also hate this trend in modern designs where every corner is rounded, especially on websites. Just give me sharp, right-angled corners. At least online, there are plugins to remove them. Just wish it was this easy in real life :(
Its not the rounded edges that ticks me off, its the fact they they make a blob shaped
They say blobs are softer, more inviting and thus less intimidating
@@imeakdo7 if i were buying things at the store i would avoid the blobs
"Sanyou, not Sanyo" ;)
Woah! Now that's some rapid unscheduled discombobulation on that chip/board. Nice fix, putting a good one together from two damaged ones. Been there, done that many times.
The time scale is hours and minutes - the dough has to rise first, then it bakes. Dany, you teach us electronics, we teach you baking. 😂😂😂
Nice repair. You might find that the machine has test modes if you power it while holding down different buttons. My one has a test mode that pulses the motor, cycles the heater and makes all digits on the display count from 0 to 9.
Your patience is admirable 😊
I forgot I have one of these. Baked a few breads and lost interest after that like most people.
I like Pita and whole wheat buns more than bread loafs.
habiiibi ... love your work and your "lets try to fix it videos"
kudos from ethiopia✌
You have forgotten to bake a bread. 🙁
Cat so right...and thnx for sharing...
Very interesting.
Learned a lot.
Thank you!
That looks identical to the 120 volt North American Black and Decker model B2300 bread maker. It heats the pan for a bit before mixing the ingredients.
I have 3 of them, they all work except for one program setting (Knead only) . The same program setting failed on all 3 units, otherwise they all work with the other programs.
Nice work.
I would love to see you bake something in this machine & make a video
Thanks for posting
nice insight. should ring-test the motor stator apart from rotor when disassembled
13:04 I have that same exact motor that is on the left!
hi after years of watching you i just realised u are from czech! měj hezký den a pokračuj s tím co děláš
Opäť ti chcem poďakovať za toto video, pekne si ho dal dohromady, ešte môže nejaké tie roky pekne slúžiť. Súhlasím s tebou čo sa týka dizajnu tohto zariadenia, ani mne sa to vôbec nepáči, bohužiaľ takto dnes vyzerá hodne spotrebičov (ako detské hračky) a ten "hračkársky" dizajn sa dnes bohužiaľ nevyhýba ani meracím prístrojom, ktoré by v prvom rade mali vyzerať ako seriózny kus techniky. Celkom ma prekvapilo, že tá riadiaca doska má napájanie z klasického trafa a nie spínaným zdrojom, je to ale staršie zariadenie, dnes by tam asi dali spínaný zdroj. A čo sa týka toho failu s tou doskou displeja, ako si sám správne povedal, nikto nie je dokonalý a chyby sa proste stávajú, je dobre že si toto video uverejnil, lebo je tam spústa užitočných informácií.
Thanks
Danke!
Thanks!
thank you for your support ;)
Glad for you!
Amazing.
That was very interesting
Oh man, the breadmaker that you dismantled is 1000 times better than mine, whose every part, including the microcontroller is tampered by me.. Internet will collapse if I make a video of it. Still i make bread in it.
Gee your cat is *very* judgemental, eh. 😁Joke's on them because you got a running bread maker out of it. 👍 I do so envy your electrical and electronic skills. Really nice job fixing it and explaining the issues involved. *Thank You!* LLAP 🖖
I hate my bread maker. It takes 2 hours 45 minutes from pressing the Start button until it has finished baking. It takes less than 10 minutes to make the baked loaf disappear. I even purchased an electric slicer so we could make thinner and straighter slices but the damned loaf would evaporate even faster. Made a croissant mix in it once but adding all the butter was messy and it would explode my calorie intake for the week. 😱
I also got on the air fryer bandwagon early and ended up purchasing a reasonably (for me) expensive one but the digital display stopped working about 16 months into the 24 month warranty. Got it swapped for a brand new one and that also stopped working with the same fault so I looked on TH-cam to see if there were any videos on how to fix the -Phillips- brand name that I won't mention and there was such a video. AUD$12 worth of parts and it appears that an IC fails taking out a capacitor and a couple of fusible resistors. The short is caused by moisture from the food being air fried getting on to the circuit board and according to the clever person who made the repair video that once fixed the circuit board need to be sprayed with a sealing compound to stop the moisture from causing that same damage again. Well it did in his case and I would like to try the fix but I have to purchase the components online and with delivery plus the sealing spray the repair cost increases to AUD$63 and a new air fryer cost AUD$79.
Apologies for the TLDR off topic air fryer story but wondered if that kind of moisture causing short could happen in a bread maker and could cause motor and/or circuit board damage? 🤷♂
I had a lathe belt turn to dust and string like that while I was using the lathe. One minute it was working fine, the next minute it made a weird noise and stopped.
the angle of the display might make it easier to read if there's kitchen cuoboards above
well covered as always!
Could You share ways to disable auto cut-off on short-circuit in laptop adapters?
I've several salvaged, and on running high current loads (within adapter rated output limits), it still senses it as short-circuit and cuts-off. I've tried with scr based power regulators to soft-start the load, but the adapter keeps cutting off the output.
it works fine with very low current loads, e.g. lamps/LEDs (low power rating)
Is there not a third wire that needs a resistance to ground or vcc to "detect" the laptop and power okay?😅
The heater may come on at the start in some programs to melt butter and "wake up" the yeast.
At least you got a good pop out of one of them, not bad!
3:25 i really agree with you, i dont know why designers design their cases in the ugliest way as possible
because this device would be mainly used by a woman and women won't buy a square box.
@@g4z-kb7ct On a related note, is it me or do designers tend to put feminine names on underbuilt “sissy” versions of products? (See for example DGW's broken Eta “Marell” vacuum cleaner.) If the commercial vacuum cleaners (as I use) are indeed too heavy for housewives, I'd rather they just made a smaller (and lower-powered in both suction *and* electrically) version of those. Anyhow that's some fine misogyny…
Not that “butch” products are necessarily all they're made out to be, either: In Australia HPM's power-boards have stooped to the USAmericans' level by disclaiming that they're for “residential use only”, and *this even includes their overpriced “heavy duty” models* (which of course contain the same flimsy socket contacts as the basic versions). Ningbo Kaifeng power-boards have much better socket contacts than anything else you can buy new (at least in Australia) so I've bought nothing else since…
No cake ending! Gutted! 🙈🤣🤣🤣
The non-stick quality of the baking pan is what always limited the fullness of my bread makers. The bread get stuck in the pan. The other problem is the seal of the paddle shaft in the bottom of the baking pan. Digging the paddle out of the finished loaf was another issue.
❤
Oh wow, had an exact same model as this die on me.
Did your incident actually trip the breaker? Anyway, nice video once again!
První verzi měli moji rodiče a vím jen že taky odešel řemen. Asi nebyl nic moc. Jinak díky za zajímavé video.
They got 2 mixer paddles now mine only had 1 lol😂
I can't imagine being in a poorly ventilated heated box did anything good for that motor either... Nice repair!
You should have baked a loaf of bread.
i realize that the belt is broken or missing when u turned the tow shaft of the mixer at 1:46 ، i have the same model with the same fault they must use mechanical chain drive or gears , the belt melted because it was near the heater .
Môžem potvrdiť, že tie ozubené remene sú "kurvítka" a na mojom to tiež skončilo ich rozpadnutím. Chlebopiecku som potom vyhodil, ale stihol som z nej vybrať sklo, ktoré malo presný rozmer, aby pasovalo do skrinky pred hodiny (elektromer) v garáži. 🙂
Great video but very disappointing that you didn't make something with it...
The belts disassembled (crumbled) in my breadmaker too. Such a crappy design. And everything is from China now and they put a different label on it depending on who ordered it. ETA was once a quality product. ETA Hlinsko. My 40 year old kitchen robot ETA 1•012 with all its accessories works fine. I just had to replace some safety pins that got worn over time, but they save the motor from burning if you decide to overload the machine by putting too much in or pressing too hard when grating or slicing or using a meat grinder and throwing too much into it.
There most be a thermometer in the case somewhere.
- Mom, can we have a Thermomix?
- But we have a Thermomix at home.
* Thermomix at home * :
I asked you several times to make a video about all your incandescent lights 😫
I have never seen a cooking machine require a chief to trouble shooting
For some other annoying beeping device I put a tiny screw a few turns through the buzzer hole. Done, volume reduced :D
Can't you test the coils of the motors without the rotor with your ring tester? And the most important I want to see the bread!
Will be chleb making video?
Rip
I was never a fan of the bread out of these kinds of automatic bread makers. Not because the bread wasn't nice, it tasted great, but because the paddles in the bottom always left a weird shape in the bottom of the loaf. That and I could never get perfectly straight and even slices, even with the slicing guide (that said, I usually left the slicing to someone else, so perhaps I'd get better with more consistent practice).
OOOOOOOOOOOPS!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
12:13 🤣☺
I wanted you to show us the identification on the chip... but I suppose it's to late with a hole blown in it. ;)
There was a partial ID shown. It's a custom re-badged microcontroller so the number means nothing. Breadmakers have lots of weak points causing it to be scrapped, the microcontroller being custom is one.
Hi man :) Can You answer me? :) Best wishes!
Wouldn't it be easier to go buy a loaf of bread at a bakery? 🤣
This bread maker mixes breads inside it cause I never used one.
now bake/make some breads in it.
Technically I hate cats! However yours is so good looking that it breaks my heart! Even big bluffer Rossmann can't compete with his 3.
Make a bread in it😂
How can such a small motor consume 80 watts with no load ? That's a catastrophically low efficiency.
Now you have to learn how to bake bread. I'm no expert but I know bread needs to rise and proof. All of that takes time. Which is what I imagine those time delays are about.
You can't make a cake without breaking eggs, so it looks like you can't make bead after breaking your bread maker. 🙂
😄What's wrong with right angles? Ask Rudolf Steiner or his followers, the anthroposophists. This machine nicely fulfills their desire to avoid right angles.
I was hoping to see a baked loaf of Czech bread 😀 You can make marmalade in that bread maker?
I also hate that modern devices look like blobs. Or cars that look like eggs with 4 wheels on it. Ugh...
I agree
my most recent mess up showed today when i built a prototype for a remake of a 30 year old product. i copied the parts of the schematic i was going to re-use for the new design.
there was an active high enable signal tied to ground. the schematic pre-dated integrated cae/cae software, so somehow the layout still worked.
sometimes, stupid things happen.
one is allowed to laugh about them.
cae/cad
Controlling a induction motor with a triac is inefficient. That’s why the motor failed
The triac only turns the motor on or off, it doesn't regulate the speed.
@@DiodeGoneWild yeah but you could hear the motor pulsing, right?
@@user-mz1uh4ju1n pulsed operation is different from phase cut. It allows multiple full waves instead of partial half waves.
@@ovidiulu yeah but isn’t this bad for the motor?
@@user-mz1uh4ju1n Even running the motor at constant load and speed is bad for the motor as it will eventually wear out :)
Phase cut induces more losses so it will heat-up more but it's smoother mechanically, pulsed control relies on inertia so it will be more harsh mechanically. In the end it comes down to what is better for each application.
Would have been better to download and read the operation manual first because breadmaker can mix+bake or just bake. Of course when just baking the motor doesn't turn. Wildly pressing buttons is not a good idea. Next time you get something like this read the manual....
Kitty not approving
No longer see the tasty bread mixes in grocery. 3d printers suffer same faith
