What's inside a bread machine and how does it work, fixing it (it doesn't mix). Please support this channel on Patreon: / diodegonewild Instagram: / savage_danyk
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.
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.
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
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.
@@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
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.
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.
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.
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
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.
"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.
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 :(
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.
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.
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.
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.
@@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…
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 RU-vid 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? 🤷♂
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.
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 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.
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 .
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)
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. 🙂
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).
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.
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.
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.
😄What's wrong with right angles? Ask Rudolf Steiner or his followers, the anthroposophists. This machine nicely fulfills their desire to avoid right angles.
@@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....
