Pulled a ~ 600 € DeLonghi coffee maker out of the dumpster and invested about 50 € in spare parts (water tank, grounds container, and a new magnet valve). Seems like I have a new coffee machine now

Is it just me or should the insides of a coffee maker not look like the exposed workings of a jet engine

Tbf this is a relatively fancy espresso maker.

Looks like a "super automatic" espresso machine.

It grinds the whole beans and typically they also have a doser (measures the weight or quantity of the ground up coffee beans), then it tamps the grounds, brews the coffee (which is some at a specific temperature and pressure), then ejects the used up coffee puck in a bin in the bottom of the machine.

The mechanism for the automatic tamping, brewing (with pressure valve) and ejection is one very complicated piece as well as the controls for the motor that operates it. Then there's the temperature and pressure controls for both the brewing of the coffee and the milk frother the machine likely has.

Edit: Video with partial teardown and which shows how the internals operate

If you're not drinking turbine coffee whats the point?

- If it doesn’t taste like JP-5 I don’t want it.

I recently replaced the heating element in my delonghi coffee machine, and was also surprised to see how wild it was inside

What do you do for a living and how do you know how to fix coffee makers?

@workerONE Officially, I'm a computer scientist 😉 But over the years, I've fiddled around with enough electronics and mechanical engineering as well that I'm overall pretty good at fixing stuff 🤷

@floe @coffee that’s totally fucking awesome

Way to go!! I didn't realize these were so fixable but not surprising. My old Gaggia was easy to find parts for and easy to work on.

@agent_flounder Yes, big kudos to DeLonghi as well. They could just have glued everything together into one big epoxy block, but no, they chose to make it actually repairable (and even let you buy replacement parts). 👌

- Big W for DeLonghi there for sure. New respect unlocked :) it looks like it is well designed and laid out too.

- I think they make too much money repairing complex coffee machines to make it difficult
  
  Also unlike phones they don't need to make them small as possible and able to survive being carried all day, so don't have those reasons for making things tight and sealed

Hot damn, nice one

@floe @coffee awesome! 🙌

Pretty neat!

Wow great find and work in fixing it up.

2

That’s fantastic! 👏

It's amazing what a little curiosity can do. Most would consider the machine dead. A friend also had a similar coffee maker that stopped working and just decided to pop the cover off to see if there was anything obvious. A quick replacement of a deteriorated hose and they were back up and running when it otherwise would've ended up in the landfill.

1

Amazing dumpster find! How long did it take you to fix?

1

@gronjo45 I'd say roughly an hour to take the cover off and find the broken valve, one week waiting for the replacement to ship, and half an hour to put it back in 😉
