Bodum Coffee Grinder. Looking for the problem.

- This is my first video on this coffee grinder. It hasn't been letting the coffee grounds through to the glass container. As I dissected it I found lots of issues with wiring.
I don't claim to be the right person to fix it as I have 0 experience with electronics, but I thought I would share my journey and see if anyone has any helpful suggestions.
Also, I'm sorry for the black screen time. I'll get a phone mount in the future.
Mine was failing, bogging down and making a snapping sound. This video was helpful in the dissemble. Those screws under the rubber feet were the ones I missed.
It turns out the problem was not the plastic gears as I suspected but the clogged exit chute coming off the side. The grinder was unable to push the coffee out. Mine was totally packed with fine coffee grounds. Bodum replaced mine under the warranty. I’m going to set it for a more coarser grind which may keep the chute clear. Also I suggest if this problem comes up again that you attempt first clearing the chute with a thin wire brush or something.
I wish Bodum would reply to my email about this same issue
I know this is pretty old and likely you don’t have it anymore but. That plate that is under the gear with the springs and ball bearings is most likely your culprit. The side the balls roll on will have indentations from all the times it has had issues with getting caught up. Flip it over to the other side without any indentations and reassemble.
Thanks for taking the time to show this.
Thanks for the video, David. I've got one of these coming in the mail. I know it's 4 years late, but I wonder if it's coffee that is getting in the teeth of the gears, and binding them up? They are made of nylon so they are meant to be self-lubricating by virtue of the nylon's ability to slip. Another video showing this grinder is experiencing the same issue. His has slowed down as well.
Well I have spent lots of time on my bodum which would only gring for a split second. It appears I have got it working but it still has a mind of its own. I may post a video
Any advice? Mine does the same thing. It will work for a split second then stop. Sometimes it will work for 4-5 seconds, but only sometimes. I’ve taken it apart and cleaned it and it still does the same thing. I just took it apart again and now I can get the start button to work at all.
@@zig23 it is the 50 k ohm bidirectional pot. AKA the timer knob. I took video to post my first youtube. It's hard to take off the board to fix. It was dirty and no way to spray in Deoxit cleaner and it appears this pot is undersized for the current draw . Did you ever smell any hot electronics smell? I needed to take off the board and clean but most importantly some of the spring contacts needing bending fir better contact. I'm thinking the much current caused them to bend. This seemed to fix mine. But then it didn't. It seemed so illogical but if I unplugged the unit I sometimes had to press the button 20 times which gave me a short run. After 10-20 times then it would run the full time. I used about 8 seconds as I was aiming for 28 grams of grind. The pot has a larger operational circle than the knob so you need to do some time tests before you press the time knob back on. I never had wired break but I did unsolder the switch and extended 2 wires as they were a bit short. Depending on factory worker I think wire length varied. It is possible to take apart if your wires are long enough. Mine barely were. I racked my brain trying to figure out how they assembled this thing. I think they did glue the top on last. So mine worked since I posted last but started doing it again last week. Worked, then not, then worked. Ordered the Baratza encore from burmancoffee.com for same price as amazon but got free # of green beans. Took for days just unpacked it. I need to make my youtube on how to fix this. It really needs a new 50k pot. It has 3 contacts. Measure ohms from center pin to one of the others it will go 0-50 k ohms while center pin to the other one goes 50k-0. Really need to find a replacement part. I also need to make a youtube on how to hack a airpopper to roast coffee beans.
@@elkskiutah8204 thanks! I took it apart and cleaned up the board, but I broke the on/off switch beyond repair. I’ve been trying to fix this for months and then realized that it’s not good for espresso. Just ordered a Baratza instead. They are apparently much more fixable and they sell the parts.
@@elkskiutah8204 I used to roast coffee too. I started with a popcorn popper and then built my own bbq rotisserie roaster using a 5lb. basket. Here’s an old video I made with my popper: ua-cam.com/video/15x8md2cRWA/v-deo.html
@@zig23 andy, I think I found my bad part . It's the momentary switch 6$/100 on Amazon. My pot fix from before seems to test ok. . This helps explain why I had to push the button 20 times to get it working. But then it worked for months. 100 6x5x5mm 4 pin momentary switch. Also I think these fixed are best done by taking off timer knob. And 4 screws on bottom. Separate top from bottom until switch binds. Remove flat plate coffee falls through. Then undo but from timer switch. The red button extension tube will fall off. Test pot and it should be smooth 0-27k. And the circuit has caps so the value will change slowly from meter voltage. If pot looks smooth then test 4 pin switch. Top connected and bottom connected. Pushing should make contact top to bottom. And not sometimes. Sunday I will have 99 extra. I could mail you a couple for postage. Probably 8mm tall with legs so will need a padded envelope. Not sure how to contact on youtube.
How do you remove the casing from the internals? There appear to be three screws sunken deep into the casing. It seems like they are riveted. Nothing fits the heads.
At this point all I can remember is that I had to take the rubber feet off the base... After doing this it exposed the screws that held it all together
Mine weren’t riveted. I was able to use a phillips head to get the recessed screws off. Getting them back on was the tricky part!
In mine the little ball fell out probably the one that’s sitting in the speing would this be bad? Bc i have no clue how to open this grinder as i don’t have the right tools...
Did you ever figure it out?!? Please do a follow up!!!
I switched to a hand grinder, because mine quit working. I just tried it again and cleaned it well with a q-tip, still no luck. Mine seems to spin, but the beans don't go into the grinder teeth unless I put it on the coarsest setting. I'm thinking some of the plastic has warped.
Mine is doing the same thing. I think the motor has decided to start turning backwards. I suspect the polarity has reversed somehow but not sure if its related to the motor or the electronics that are connected to it.
Thanks for sharing! Great job!
I"m the person who just gets a new/better machine. 😂
Is there a video that show how to disassemble ?
where does the small metal part seen on 0:28 (middle lower part of the screen, closesr to you) come from? It fell off the grinder when I was cleaning it and it stopped working after that. was it in the power button?
Nice try. Did you ever fix your problem? I don't think you needed to take the gear box apart but it gives us an idea of what's in there. When you're putting it back together, make a video. I've taken mine apart to clean it but as you mention, the wires are so flimsy that they break off. It's a real pain to get it all back together. I use blue putty (Sticky stuff) to hold the small start button in place while I screw the circuit board control nut in place. The hardest part is fitting the on/off switch. Basically, it's just not meant to be taken apart...and getting the two plastic rings to match up at their respective positions, if you haven't marked them before disassembly even after all that, now it doesn't grind properly, too coarse and uneven of a grind except at the very fine settings...a real pain.
I ended up trashing it. Lack of knowledge and lack of time. It sat to long in the work shop. The blue putty idea would have been perfect... Too many times that switch got put in the wrong position. Haha
For the two plastic rings, (If you dare battle the on off switch again) there should be an arrow and a tiny plastic nib on the other ring so they have a place to match up.
Best of luck and sorry I didn't make a follow up video.
Too bad you trashed it. I need the on/off button and the micro switch. I may just by-pass those.Good on you to have spotted the nib and small notch on the two rings. Not very obvious to spot. Took me a while to do so. I think, in the factory, the very top, which has the button and timer controls) of the casing is separate from the main body and it's easier to work on then they must glue the top. I've looked to separate it but doesn't seem possible...
@@HagmanDavid dude, i hope you at least recycled
So sad to see this, compared with its advertisements... the best plastic coffee grinder?
Hey David can you tell me how you got the main on off switch off. And how did you get the board off. It looks like you broke the red switch?
I didn't break the switch... But I definitely broke some skin trying to fit my fingers back there to force it in and out. It was difficult!!! The switch has plastic nubs or pins that I would flex to put in and to get out. My main struggle was accidentally putting the switch in upside down.
Which nubs? The red tabs on the switch or the black ones in the ring around the switch. If the wires were longer the top and bottom would come apart making it easier to get to switch. How did you get the board off? I have not tried pulling on the big red tire knob yet. Is that all thats holding it in place?
@@elkskiutah8204 if I remember correctly, the tabs on the black ring around the switch. And I can't remember how I got the board off. I'm sorry.
I wanna say there were screws holding it from the back side. I remember taking some pads off the bottom and using a long screw driver to loosen screws. But I don't remember if those were the screws for the board or not. Again I apologise.
Good luck! :)
I got it all apart. That switch is a weird thing. Designed to pop in once.
Do not try to take off the switch I have a posting in here of how to take this thing apart and fix the components on the board if you're having certain problems It is not the grinding mechanism it's the timing board potentiometer or push button switch the on/off switch is very fragile and it's really up one time assembly part
Did you consider that the burrs May have been dulled? I’ve pulled a pebbble or 3 out of mine over the years.
Hi Dave how did you take it apart , ive taken the 4 screws out what do i do next ?
Kind regards
Ian
It's been a while since doing this video but I believe I had to take the rubber foot pads off to find more screws, much deeper inside the unit.
I hope that is helpful
Respectfully,
David
@@HagmanDavid Hi David I’ve have found the screws and removed but after that, it does appear to drop out from the top any guidance ???
Kind regards
Looks like the gyroscope is warped and you might need to give it a papshmear.
I wasn't able to fix it. Neither was I able to have someone better at fixing things fix it.
Just did mine, the board was shot so I bypassed it and now it grinds when I turn on the switch. Only difference is having to count to ten.
@@RetiredPilot I should have had you do mine. Hahaha
@@HagmanDavid It wasn't hard, and mine had enough wire to remove the cover without removing the switch. I just snipped the four wires and bypassed the board and the switch on the top. I now have a manual bur grinder.
Cheers
@@RetiredPilot Thanks for the tip on bypassing the timer board. I just took apart my son's grinder to clean it out and figure out why it wasn't grinding consistent (the bur was not seating properly and not getting locked down when the hopper was turned). He also told me that the timer didn't seem to be working. Sure enough, I push the start button and it only runs a second. Could you share how you wired to bypass the board? Thanks @David Hagman for you video as well.
@@vhovar1 A wire comes from the switch to the board and a wire goes from the board to a small micro switch. When I did mine I also bypassed that switch. so I cut the two wires from the board and connected the wire from the switch to the wire on the other side of the small micro switch. Now when you turn on the switch it directly powers the motor. It will run as long as the switch is on so count the seconds you need to grind.
the idea of your video is good - making a video with a phone upright is terrible, why can't you do a horizontal shot and give more wide view? Also recording with one hand and trying to work with the other is real bad... a phone is not a camcorder since it has no stabilizer
Hm. I'll side with the producer here. If we removed all the vertical hand-held how-to videos from UA-cam, I for one would be a poorer man for the doing. I could follow along just fine despite the production flaws you mention. It takes a LOT of work to make a good how-to, and most fixers are fixers first and you-tubers/video producers second, if at all. I encourage all those who take the time to dump out their efforts for all the lesser fixers out here, vertically or horizontally produced.
