I've been drinking coffee for over 40 years, never knew how the maker worked until now. I see you made this 15 years ago. You're most likely working for NASA now. Keep up the good work!
Wow this tutorial helped me so much. I tried cleaning my coffee machine with vinegar and let it sit for about three days.. With no luck. Once I got to that little pressure ball, I cleaned all the gunk out, and had a great cup of coffee, thanks for that tip.
Yeah! White vinegar has about 10% Acetic acid in it. Good at getting hard water scale out of there! Did you know that Oil drilling rigs use it in the drilling process? I would caution against using it in the coffee maker though. The environment inside there is already slightly acidic from stray coffee grounds. The bugs inside will be adapted to that environment. Light acid cleaners are nice for loosening up crud but normally it leaves a black hydrolyzed gunk behind that you have to scrub out. Bleach has high PH and oxidizes the crud pulling it into the solution. The sudden change in PH specifically targets what's growing inside there. I normally go 10% bleach and let it set for 30 minutes to an hour. Rinse it out and run it a couple times without coffee. 2 years and going strong, I'm proud of it XD.
Wow, thank you very much. I opened my coffee cooker and made a wrong connection until today I stumbled on your video which gave me the correct way to have done it. Thank you very much for making this video......
Now I understand why I hear a sort of plastic ball while the coffee machine is pumping up boiling water. It is the ball check valve. Very interesting. Thanks for posting
this is a brilliant vid! thanks for explaining the mechanics as well as the physics behind all this. i really appreciate that you even live-demoed the whole thing so your viewers can truly understand
This was helpful, ty. I'd never understood the geyser effect and just spent 5 minutes looking for a pump instead of a 1-way valve. So easy fix thanks to you.
Excellent video. I just opened a similar coffee maker and was looking for a water pump but didn’t find one. I love it how manufactures find ways to make things as simple as possible to save money. It is very cool. Thank you very much for a great job.
Thank you so much! I was about to give up but your suck/blow demo saved me from throwing mine in the trash. I actually found a whole coffee been stuck in the tube which stopped full flow. I took it apart and back together and it was working even worse. I put the tube with the ball valve on backwards!
great video! very interesting! watched it with my four-year old cuz he asks me every morning how the Coffee Maker works! thanks for showing us! I learned something new right along with him!
I had always wondered if there was a pump in a coffee maker, or if somehow it worked without one, but I never took one apart. Thanks for sharing your informative and entertaining video!!
Really very good and concise explanation. Didn't waste time, clearly explained principles and excellent demonstration . your a better teacher than alot of engineers!
12.3.2021 That is awesome! I just fixed my very old favorite percolator, (internal wiring problem) and always wondered HOW it worked. The VALVE! That explains everything. Thanks man. 13 years later Mr. Brown Retired Software Engineer.
Good job. My Cuisinart coffee maker stopped brewing. Water got hot, but would not flow up tube. Took rubber hose off, removed and cleaned “one-way ball valve” and now works perfect. You saved me $100 from having to buy a new one. Thanks!
Love this guy, lol. You know he’s an interesting character when he zooms in while he is making his bacon flip tongs geyser display (with a glove twice the size of his hand, lol) and you can see juggling batons in the background, lol. Now I have to see some of his other vids! 😆 👍🏻😎👍🏻
Great video, fixed my Mr Coffee my heating element was completely blocked with calcium, used some bailing wire and a 22cal, gun cleaner wire bore brush and got most of it. Ran some vinegar through a couple of times and good as new!!! Thanks
Thanks for the video! My coffee maker broke and I'm going to try to fix it. The heating element is not working, so, thanks to your video, I'm going to disassemble and see if I can repair it and save some money and keep some plastic out of the landfill
Thjank you so much... I have a mister coffee that is exactly like this and took it apart to clean it... you answered the question as to which hose goes where.. and How.... now its all fixed!
most of your viewers probably never saw how a old fashion percolator coffee pot work before,,, unfortunately I'm old enough to remember LOL,,, real informative video, I think I can fix mine now, Thanks
Good Video Professor! You are destined to create great inventions. I appreciate the "How it Works Tutorial." Nice presentation, well spoken. Just nerdy Enough For We Nerds; Snort Snort Snort.
@Crazy Builders very nice video guide , but dud that's soooo crazy playing with "BOILING" water and "electricity" if it were me I wouldn't do it or at least use a pipe extension to extend the boiling water away from me and the electricity glad you're not hurt and thanks for the video
Excellent video. Incidentally those coffee element bullet fuses are also found inside the control panels of these fancier electronic model ranges. if the homeowner sets the oven on self clean, which goes to 900f inside the oven and the oven control section gets above 300f, which could damage the controls, the fuse melts and the controls no longer function.
First of all, thank you for taking the time to do this break down for all to see and experience! ------------------------------------------------------------------------------------------------- Loved your informative video, not all older coffee makers are made equally of course. Only part that I got a kick out of was learning about that one way ball valve in the intake hose. ------------------------------------------------------------------------------------------------ The few that I've broken down from long ago pre 90's did not have that great little feature, interesting the way of technology and how even the simplest forms take on new innovative directions! ------------------------------------------------------------------------------------------------- Again, thank you for your time and efforts!
I have (or had, until today) an older Sunbeam coffee maker. We bought it in Oct of 2003 and it just stopped working today (July 12, 2014). As I was taking it apart to see if I could fix it, my wife got your vid, I had figured it out (I'm sure these things are made specifically to be non-repairable), but decided to see what you saw, in case I had missed anything. It works the same (the Rival we got to replace it looks like it does, too), the only differences being that the one-way valve is in the plastic rather than the tube and looks like it has a diaphragm instead of a ball, and the security screws are a different design.
very interesting, was always curious how these worked, if there was a pump of some sort. a bit bothered by your disregard for safety by creating a geyser of boiling water with just about no meaningful safety precaution. pretty sure a couple of binder clips could have helped you prop up the tube, and then put the outlet and yourself a safe distance.
....So, the main fail with the system is the 'furring up' of the valve as limescale accumulates and calcification occurs over time and causes the valve to malfunction. I never knew that, my last coffee maker lasted 12 months before it 'died', and that is no doubt why. Great vid, well done.
