- Repairing a Samsung eco bubble washing machine main control board.
I originally bought this washing machine as spares or repair as I wanted the motor to make a wind turbine. The washer was in very good condition, and it seemed a shame to just scrap it for the motor.
The wife also decided that she liked the look of it and asked if I could repair it.
After re-soldering quite a few dry joints, the drum still would not move at all, so I checked the voltages to the motor control chip which seemed correct. I ordered a replacement chip which was a IKCM15F60GA from ali express, the chips I received were actually faulty. I think they were copies or rejects. I ordered a one from mouser.co.uk which worked perfectly and is still working.
Got a similar problem on a s/h machine we bought cheap for spares. Found the original problem was a broken wire to the heater thermistor. Did a couple of test loads ok, then next time the thing would do a wash cycle and stop when trying to spin, got into the board and after a couple of taps with the screwdriver off it went, so I’m now removing the plastic base and the silicon goo looking for a dry joint ! Nice to see you’ve done likewise 🤗🤗
My wife just complained that the washing machine is stopping during its cycle, no errors on the display. I did notice it's always when the machine needs to spin is when it bugs out and stops working. Sometimes it spins and sometimes it doesn't. I do board lever repairs on Apple products and I've never seen a more terrible and deliberate attempt to stop people from repairing their devices than what Samsung has done with their EcoBubble washing machines! Using silicon to cover the entire board and prevent the owner from removing the board from the housing is a dick move from Samsung. We own the 6.0KG version and the board is a little different from what you own but it's covered in the silicon to its teeth! Removing all the silicon is proving to be near impossible!!! I won't give up, this silicon hasn't seen the last of me! Thanks for sharing your experience!
ive replied to this further down, i 'pryed' the whole mototr control section from the plastic housing, worked much easier ..
im on my 3rd chip replacement over this year, but this last one seem to of taken the fuse, resisters, and its looking like main chip out on the board :(
@@gadget7894 My board is not like the one in this video but uses the same silicon sealant and it's glued from the bottom and top, near impossible to remove without causing more damage. It's still a miss and hit with the machine, sometimes it completes the cycle sometimes it doesn't. Once it dies completely I will then rip out the board and repair it if possible.
I’m here for the help to repair the board but I cannot resist the reply. Apple used to make user repairable/ upgradable devices themselves till about 2014. Thereafter they began to weld ram onto boards, even on iMac consumer devices, seal up units etc etc. Drove me crazy.
It’s wrong that Samsung do it but Apple long since forgot about doing the right thing also.
Cool Video, good information! I have heared that this washing maschines have a Drum mounted on a Aluminum alloy which dissolves over time. The suds container is made of plastic and is glued so that it cannot be repaired.
Thanks. I think this was the first repair video I did and glad people still find it useful. I think most washing machines in the uk are mounted in a similar way. The washing machine is still working fine since I repaired the board in the video 👍
I had a similar problem with our Fridgidaire washer and it came down to dry joints and a relay that had become detached on all pads. Resoldered the relay with a generous dollop of silicone to secure the relay and prevent a repeat of the problem and it's still running 6 years later.
Nice. This one is still working fine too. In fact you'll probably see it in the next couple of weeks as I'm just about to start recording another Samsung eco bubble that my wife just bought for £27 and it's in really good condition but stops randomly during a cycle... and I was going to show this one still working since I fixed it 😂
thought i would just add my experience with this too ..
i didnt 'cut' the bottom off my control unit box ...
i used a plastic tool, and pried the whole PCB, along with its goo out of the plastic shell in one lump...
then access was much easier to get rid of goo, and work on PCB
(i felt was less risk in cutting board, and plusit left it in a much better state :)
well 3 months have passed, and my repair/chip replacement has been going well, but its just stopped again :( ..
we need a better/stronger output chip (i got my replacement from uk.rs-online.com )
shame i cannot add pictures here ? to show other people who have posted about my "better" method of getting the board out , so you get better access....
well after replacing the chip, it did go AGAIN, so clearly they are weak chips :(
but sadly this time the chip when complete short circuit, popped the fuse, and the 'protection' resistors inline with main chip....
replaced all these ! and its still not working, althou theres now NO error on screen theres still no motor movement :(
not really sure what to do :( other than new board ?
Surprised at Samsung using a plastic drum pulley! My new Hisense Inverter cost only £238, and has a metal drum pulley!
"Ally"-express? ... I call it, "Alley"-express!
A couple of people mentioned as in "ali baba" so at least I know now 😂 This machine is still working great. I recently got another but it has a different design now and is direct drive so doesn't have the motor / pulley arrangement like this one does.
Hi to all having the same problem. Mine stopt turning too. however, after the repair I did I'm not really convinced that the IC breaks. After I cut the legs of the IC to take it gently out I saw that some of the thin pins had bad solderings. Another video on youtube also shows that. Well since I cut out the IC and had to replace it I looked arounnd for the IC to buy. It is not really good available at stores. I found the IKCM15H60GA at Farnell. Also 10euros but they do not charge shipping costs. Check that the IC I bought is a slightly different type since it has an H instead of an F in the partnumber. I think it's an upgraded part. It worked in my machine after some PCB trace repair since I damaged the board an invisable bit close to the screws of the IC. When I removed the screws I accidentally bent the PCB and two tiny traces snapped. So take really good care for the PCB. It's very fragile....Good luck to anyone who has to face the same problem!
Hi, yes they are prone to dry joints also. The machine I repaired had quite a few, but also the IC was blown. 1st thing would be to check for dry joints, if it still doesn't work, then the IC is probably blown. Also beware of counterfeit IC's from China!
Mine had dry joints on the IC also. Big thanks for the helpful info ! My PCB had already been replaced during the warranty period and only lasted a couple of years.
This is great. I have a very similar machine and there is no power to the unit. I've seen a few videos which have helped but are different than mine. I'm winging it here. Any chance you can offer a video on how to take the top off to get to the boards behind the face of the unit? or point me in the direction find it...
From what I remember there was two screws at the back of the lid, then it should slide back (might have to give it a bit of a tap) that should give you access from the top..I've never had the front panel off one though.
Hi, do you think the silicone was to mitigate issues that may arise due to vibration? Do you think it would be worth finding a substitute?
Well, since I made the video, it's still working fine.. and that was 5 years ago 🤷♂️
@@BuyitFixit hi, well that certainly says a lot. Do you think it was over engineering on the part of the manufacturer and was in fact redundant. Just trying to understand why they would go to the expense.
By the way I have subscribed to yours and a few other similar channels recently and love the idea that these appliances get a second life and don’t end up immediately in the landfill. Cheers.
@H2Dwoat I'm not sure. I thought it was for moisture perhaps more than vibration? Anyway it seems fine without it 😂😂😂😂 and thanks for the sub 👍I've fixed quite a few interesting things and even had to jump into the software side of things too! Like on the solar inverter or ultrasound machine 👍
@@BuyitFixit hi, ahh that probably makes more sense as it is probably a moist environment for electronics. I have used silicone spray on motorbike electrics before to try and help with damp..
We have a Samsung ecobubble 7kg machine and the technician informed us that the rear PCB is faulty and beyond repair. I have managed to buy a rear PCB online but it is of a non- ecobubble Samsung 7 kg front load machine. Can it be installed in the eco bubble machine of the same capacity?
Does it look the same? same connectors etc?If the connectors are different then I'd say probably not. If the connectors are the same it still may have slightly different software so you might have to just try it and see if it works as expected.
Aha, so this is not a direct drive motor! :)
No. Not direct drive but 3 phase permanent magnet motor. Seems it uses the motors coils to measure feedback for position sensing.
It uses Inverter technology
I once gave up on a DE door error Samsung after I replaced the lock won’t ever do that and check it better , not sure with pcb though so hard to diagnose at times for an amateur like me
Sorry for the late reply. I had been thinking of doing a short video on testing basic components such as transistors, resistors, diodes etc if you would find that useful?
@@BuyitFixit wpuld be brillant as a hobbyist to see a pros thought process
I wouldn't call myself a pro, but I'm been doing some video's on basic testing of components, which should be released either later today or tomorrow.
May i ask for the solutions in no power problem..
Thanks for the help...
Check power going to the board then perhaps dry joints? If you have power there. Could be a number of things.
Hi, we've got a Samsung WF90F5E5U4W machine and we're now finding that it's stopping mid cycle. Any suggestions? Thanks 👍🏻
have replaced it, but the rotation is still weak, only up to 104, not up to 1400. what do I have to do???
I have similar isseu, but didn't get to check anything, as i can't get the top cover off, any directions, how do you do it? I've unscrewed everything stucks at the from?
Two screws at the back, then the whole lid slides back. You may need to wiggle it a bit side to side.
Hi! Thank you for your video it was really full of information
I have a Samsung washing machine eco bubble the motor won't to turn on I changed the main power CHP number ikcm15f60GA it works only ones and then stopped working
I bought the new chip but i did not change it yet so I wandering is there any other things to test it before I fits the ic.
Thanks in advance
Hi buy it fix it and everyone. I want to repair my elderly neighbors Dyson washing machine control board, the first 3 words out of the 6 on the digital control board are to faded to understand, what type of metre is best to check for faulty components on the PCB control board please, and is there any tips or advice anyone can give me please it's for a good cause. Well done on fixing that circuit, just getting to it looked extremely difficult never mind repairing it. Great video thankyou.
Thanks 👍I use fluke meters but they are quite expensive if it's not something you are going to use often. Get an auto ranging meter as they are easier to use. Perhaps have a search on Google images for Dyson washing machine board as other people might have repaired one and you may find pictures of one. I've not worked on a washer for a while but I'm looking at another Samsung one at the moment. Video soon...
Hi buy it fix it, thankfully I got a few auto metres but I don't know what setting to use when checking the little capacitors etc to find which 1 is faulty on a circuit board, could you advise me please, and also when taking readings how would I know iwhat capacitor etc is faulty please, especially if there's only one of each, I hope that makes sense. Great repair many thanks.
Capacitors are a bit tricky, you can't normally measure with a meter unless it has a capacitance mode which a lot don't have. You could always get one of those component testers. I've got one they are very handy. Just put the component in and it will tell you what it is. Capacitors transistors etc. They are about £15 for one on amazon. Mine's a white box with a screen and a button on it. It's also rechargeable.
these washing machines are terrible.
we got it fixed for 250 pounds because we tried all of this plus more and it still wouldnt work
then the motor broke and yet it was still under warranty but samsung did not give a crap at all.
we decided to just scrap it like this one has. dont buy them unless your using it for parts lol.
Chapeau!. You need a bigger workshop. Any idea how to remove the door catch? You have to hinge the right hand end towards the back to release the lip, but the casing is in the way. Do you remove the side or the front panel? If so where are the screws please?
Yes - you need to remove the front panel. However, the door latch was okay and the dE error was caused by a faulty PCB - you only need to remove the top to replace that so easy repair and works okay now. A lot quicker than trying to resolder the PCB.
Hi! Thank you for sharing this. My Samsung washer is about 3 years and has the same problem.
I wanted to ask:
1. Did you cover the circuit board with something or just left it without the silicone gel? What would you suggest should be used to cover the circuit board once the silicone gel has been removed and repair completed.
2. How did you fix the plastic underside of the board.
Hi, I just just left it without the silicone gel. I also didn't do anything with the bottom plastic part, although you could just put a few blobs of silicone on it, and stick it back on if you wanted.
mickr1969 Right, thank you so much.
hi, I have the same problem, which is short on pin 23 and pin 19 IKCM15F60GA, after I replace it all works except the motor doesn't rotate. motor measurement results:
U-V = 5 ohms
V-W = 5 ohms
U-W = 5 ohms
I have changed all the ic 817 photocoupler, but there is still no change
Is the IKCM15F60GA chip that I replaced not the original part?
Depends where you got it. I got two from ali express and they were fake as the quality of the logo and writing was poor and one didn't work at all and the other only worked briefly.
I ordered two new ones from mouser and both were almost identical to the original in terms of quality of text etc and its still installed and working fine.
@@BuyitFixit thank you so much.
@@BuyitFixit Hi Mick, is this the part number from Mouser www.mouser.co.uk/ProductDetail/Infineon-Technologies/IKCM15F60GAXKMA1?qs=sGAEpiMZZMtKB4wrjsn3lR0wClk1gB2cgWDyi49%2Faxw%3D
It was enough to clean the Filter, or if you hear clicking and the engine does not start, it is a problem with the brushes. If you were permanently connected to the power supply, it was a capacitor, i.e. a mains filter. Certainly not a programmer. Samsung floods with silicone and there is no possibility of a fault
There is no brushes. It's a 3 phase BLDC motor. (BrushLess D.C.)
You can buy motor brushes on ebay. I had the same problem, one brush on the spring did not come out to the motor and there was no tension, I replaced it and it works like a new washing machine
@@-ENIAC- must be a different model. These motors do not use brushes. Hence being BLDC motors.
Each washing machine has replaceable brushes, which is the basis of the service. But not everyone wants to unscrew the bolts and take the motor out to clean it and replace the £ 3 brushes
@@-ENIAC- Yes I have replaced carbon brushes in washing machines before such as hotpoints etc, but it seems that you fail to understand that the motor in this particular washing machine does not have carbon brushes. It is a permanent magnet motor which is BRUSHLESS. It also uses an inverter drive. Please google BLDC motor for further clarification
Hello. Brother i have the same problem. But i am stucked at the values of gate source and drain of the module IC in a Pcb. What should I do now? Each UVW circuitry of the module IC have a combination values of resistance and capacitance values. Though I dont have the schematic diagram,, which is not available any where. So what I do now.
Hi, I'm not 100% on the resistance values of the module, if it's the same symptoms the either and dry joint on the board or the module I would think. I would also chance the small 3 capacitors next to the module too.
@@BuyitFixit but Sir what if the resistance and capacitance are gone burst and someone have no any way to fix it with the proper values instrument then what would you say. Though a fluke may work here by any value of the component resold on
@@BuyitFixit what values of the capacitors did u change?
Sorry I can't quite remember it was 3 years ago. It was the 3 small ones next to the main IC. They should have the values written on them. They were only small. Perhaps 1 or 10uf from what I remember and all 3 were the same.
@@BuyitFixit but you are quiet sure that after replacement of the faulty IC,,, the PCB works.... I have made several practices in before. But all time I failed. Dont know whether the IC's were faulty or may be the wrong combination of resistance and capacitance values... As I watched your clip today, i am just convinced one more time to try. 😜😂. Dont know why
Samsung washers are terrible, the Samsung technician charges almost the price of the washer to repair my two years old, so I bought a new Panasonic.
What do you think could be the cause of the washer stopping mid cycle, also a Samsung ecobubble
Probably dry joints (bad solder connections) on the circuit board, or the motor drive chip failing.
@@BuyitFixit thanks for the quick reply, I'll get a multimeter on it
👍👍
Very old video, partly one of the reasons that got me started doing repair videos as it seemed to be quite a popular one.
Hi @buyitfixit i have this same and washing machine is not turning on i have open the same pcb box and fould 1 black ic/capator broken can it be fixed? Plz help me plz resopond if u want i will post the pic also kindly help me
Plz help me
Hi, it's been a long time since I looked at this, can you still make the number out on the blown IC? Was it a different IC to the one I changed?
@@BuyitFixit the ic name is SYP12270
@@BuyitFixit that's is different this is small can round in shape
@@dssvivekvicky3073 a quick search on that number says it's a PTC thermistor used to protect motors instead of a conventional fuse. Either that has just failed or something further on is shorted and caused it to fail.
man, what kind of material did you rip off the resin on the bord?
It wasn't resin as such. More like a soft silicone based compound. I just scraped it off a bit at a time with a flat blade screwdriver
Mate it gave me hell of a time! It took a whole day to peel it off even then not as clean as buy it fix it
You did not use any chemicals to remove the master silicone, the printed circuit is damaged with a screwdriver
No. It just easily peeled off with a screwdriver on the back if the PCB. On the front I just dug around the motor IC. Perhaps they might be using a different compound now? If you are having difficulty.
@@BuyitFixit thank you where do you live
Bien explicado solo no entiendo el idioma pero se save lo que hace tengo el mismo problema nadie mostro el numero del integrado del motor el lo iso veré que pasa si lo encuentro gracias saludos de chile
No hay problema. saludos para ti tambien!
Thanks for the interesting video. We have a 9kg Ecobubble. Looks to be a bit different inside. The PCB is on the back of front panel. It was a bit of a pig to get to the solder joints. (Samsung must have watched your video and decided it was too easy). Tried the dry joints but am still getting error 3c2 when I put in test mode. Have ordered a new motor controller from mouser so fingers crossed. Quick question. Did you test the motor at all. If yes, how? If not, why not? I am guessing the answer is "no" as this is the bit they guarantee for 10 years and so they will have made it reliable. :) Just interested to know.
Yes you can check continuity between the motor leads. You should get a low value reading between each of the leads when disconnected from the pcb. Also on a side note. Mine is still working fine since the repair.
@@BuyitFixit Many thanks. Just got the part from Mauser. Soldered it in. Motor works - Hurrah! Doesn't fill on main wash though. :( Think the solenoids are ok. but it isn't getting power when it should. Think a Bosch or Miele is on the cards!
ha. Weird thing. If I blow into the level sensor (which I know i shouldn't do) it starts to fill. Also fills on rinse and spin without any fiddling. It might live to fight another day! Time to google how to test the fill sensor!
@@carolinemills1282 Glad you got the motor working, not sure on the level sensor tho, have you checked the tube from the drum in case it is blocked or something? They work on pressure, so the more water in the drum casing, the more pressure of air is pushed down the pipe into it.
@@BuyitFixit Mick Thanks. I checked the tube is clear and it is. The funny thing is that it won't fill until I have blown into it. I was expecting it to fill until it reached a certain pressure and then stop i.e. I might have to blow into it to stop it filling, but not to get it to start filling. Seems it needs a minimum pressure to activate it?? Have ordered a second hand sensor on eBay. Let's see.
I have a same machine and when i plug it, it does nothing, like does not turn on at all no signals of life. Any idea what it could be?
It could be a number of things. Check you actually are getting power to the main board, if so, I'd then start checking you are getting voltages out of the power supply on the main board. To do that you'd need to hack the plastic part off on the back like I did, and remove all of the silicone stuff (which is a bit of a pain to do). Then I'd start seeing if there's any voltages coming off there. There's a 5v, and a 12-14v from what I remember.
I have the same problem, did you fix it allready?
mickr1969
I have same machine
Eco bubble 8 kg
It’s nt power
This is BLDC motor?
Yes
Those motor mounts are pathetic. My Samsung eco bubble chewed 3 out 4 mounts, and the motor came off.
Bought M6 30mm threaded rods to fix this obnoxious engendering
Interesting. This one is actually still going strong, should the mounts fail I'll keep this in mind 👍
Would have been better doing what you first wanted, turn it into a wind turbine. Samsung quality is now crap compared to many years ago.
We actually are still using that washing machine, it's worked flawlessly since I repaired on that video 🙂
Hi, how do you disassemble the top cover?
Just remove the two top screws at the back, then bash the top front of the machine backwards. Sometimes they are a bit tight, but the top kind of slides towards the back about an inch or two, then it lifts off.
Hi I have a samsung eco bubble washing machine which switches on and when i try to put the machine on it takes water but fails to spin I've tried to calibrate the machine again it does not spin can anyone please help on what's the problem is and how i can fix it would be highly appreciated thanks guys
If the drum is hard to move by hand then it is mostly because of that igbt or chip he is replacing.
G
sod that i would rather just buy another machine
Hi i have samsung washing machine ww70h5200ew is not turning the drum but i heared noisy sound
Try turning the drum by hand, see if it sounds noisy or you can hear any unusual noises. Perhaps something is jammed or the bearings have gone?
ok thanks for reply, i forget to tell the machine is not draining itself still have water inside,
Caro amico la Samsung è stata sempre una merda di produzione. La Samsung da quando si è formata come firma ha sempre dato merda di elettrodomestici. Io conosco questa marca dal 2005 ed ha sempre avuto problemi sulle schede di migliardi di lavatrici. Ho lavorato per la Samsung e ti dico che è da scartare come azienda. È l' unica marca che ha dato sempre elettrodomestici con schede che danno problemi. Ora lavoro sulle riparazioni ma di tutte le marche e di queste lavatrici come la tua ne arrivano a miglioni, noi siamo costretti a cambiare scheda ma per me la Samsung dovrebbe partire la fame perché oltre a vendere gli elettrodomestici e anche molto cari di prezzo specula il cliente vendendo schede a prezzi molto alti. Il tuo filmato è stato utile non per me perché già sapevo il guasto ... ma per migliaia di gente che deve capire di non comprare la scheda ma solo il componente. Perché la Samsung si ritiene furba a mettere una specie di gel sulla scheda. Ma la Samsung non ha capito niente che se continua cosi la gente non deve più comprare Samsung di qualsiasi elettrodomestico anche TV. Tutto qui
Hi I've a Samsung ecobubble and when i put it on a wash it starts filling fills the first compartment and when it starts filling the second one it then stops and when i put it on test mode it comes up code UC I'm wondering if you have any ideas what it would be it would be very much appreciated
Sorry not 100%. Not had that problem. Have you tried searching on the web for that fault code? It may shed some light on the problem.
