Dodgy looking connectors on the thermal cutout crimps at 19:49? I wonder if the problem with the machine is in the thermal safety circuit. The belt and braces thermal protection is probably to avoid huge flaming plastic infernos. With the control of the heaters being from a microcontroller via triacs the two most likely overheating scenarios are a software glitch or crash jamming the heaters on continually or a triac (or triac opto-isolator) failure in the usual shorted state.
I bet I'm not the only one who wanted to see the action of the coffee brewing section where a brewing chamber would close, be filled with ground coffee, have water pumped through it by the solenoid pump and then have the grounds dumped out when the brewing chamber opened again. The bean counter is probably just to detect an empty bean hopper.

[@EEVblog]

The way this things comes apart it would be hard to see in action with the panels off.

[@jorno1994]

@@EEVblog dremel to the rescue!

[@staevobr]

Regarding plastic infernos: Thermostats can latently, undetectably fail short/open. It's not likely, but it is possible. That's a single failure that leaves the device in a latently unsafe condition. Putting a thermal fuse in series with the thermostat is simple, cheap insurance that the device will not become unsafe under single failure conditions. It is far easier to put the fuse is than it is to substantiate that the thermostat alone will keep the device safe. For domestic equipment whose function requires getting quite hot I think it would be very hard to justify not having both protection methods since a failure could lead to fire, property damage, injury, or death. The safety analysis should not consider how the device is meant to work or assume that any part of it will function properly under failure conditions. Safety analysis should only consider the consequences of possible failures and their mitigation. In this case the thermostat's single-failure modes are mitigated by the thermal fuse and vice-versa. Good design practice.

[@mrbwa1]

The heater blocks tend to clog up with any minerals in the water. If you don't clean the machine, the water channels will eventually clog completely. Without water running through the block, they can get hot spots fast.

[@eliotmansfield]

You should of torn this down Clive.

[@OverKillPlusOne]

The grinder drops coffee grinds into the brew group, the the motor turns it which seals the brew group (what you called the hopper) and the pump is run (usually PWM to control the pressure) to pump the water through the thermoblock through the brew group (and this the ground coffee) once done brewing it cranks the brew group again to dump the spent coffee puck into the waste bin. For steam the thermoblock heats up employing both sides and the flow is redirected to the frother, it can also give hot water instead of steam out the frothing wand.

[@EEVblog]

Thanks for the detail!

[@kissingfrogs]

I think if Dave juiced up on coffee he may have been able to deduce that on his own.

Hot water ejected from the frother would make a mess. If the water heater isn’t doing its job you get messed on. Only STEAM!

[@OverKillPlusOne]

Rýán Túçk you obviously haven't used one of these. They pretty universally have a hot water option and it comes out of the steam wand /frother. And yes if you don't have a cup under it there'll be hot water all over. Same issue when you use them in steam mode, there's always some water at the start. They also do not always produce very dry steam. In short thermo lock units are usually inferior to boilers.

@@twjonckheere exactly my thought when i kept hearing dave try to break it down lol

[@tookitogo]

twjonckheere At my old workplace, I was surrounded by coffee addicts (I myself am like Dave and don’t care for it), and the coffee machine wore out from 15 coffee drinkers each getting 5 cups a day. So they decided to upgrade to a machine intended for heavier use (like, suitable for a small cafeteria), and someone suggested looking into the automatic dairy option (which would enable one-touch lattes, cappuccinos, etc). They quickly rejected that option when they looked into the maintenance it required: flushing the milk system with special cleaner ***twice daily***. (Only a handful of the drinkers took milk at all, so it just wasn’t worth it.) I guess that as an emulsion containing fats, sugars, and protein, milk sticks to everything.

[@twjonckheere]

@@tookitogo You can get a powdered milk version. Just make sure it's not very humid where the machine is. You still should clean it, but not as often.

[@OverKillPlusOne]

No milk goes through that machine. The Y you saw is to split between the frother and hot water feed to the brew group (the brown thing that slides into the side). If you want milk you add it after. The pump has to be high pressure to pump steam.

[@Chrisamic]

Double boiler - usually this means one for the espresso/hot water and the other for steam. This means that you can steam milk without having to wait for it to change temperature, or even steam the milk while it is expressing the coffee.
The grinder is a conical burr grinder. The big plastic wheel on the top rotates to change the grind from course to fine, by changing the distance between the burrs. High speed motor geared down for grinding grunt. It's often the most expensive part of the machines, due to the precision required in the burrs. If they are not precise you won't get a consistent grind or won't grind fine enough, and if they clash on the fine setting they can destroy themselves. People pay thousands of dollars just for a good conical burr grinder on its own.
The water pump has to be powerful because it has to pump water through the compressed ground coffee, so it's very high pressure (9 to 15 bars, 130 to 220 psi). A common failure mode for cheap machines (cheaper than this) is failure of the pressure fittings to the brew head, resulting in water coming out of the bottom of the machine.
I actually don't like these automatic machines. You have little control over how the coffee is tamped (compressed into the brew basket) and the auto frothers (tube on the steam wand) almost always stop a real barista from steaming milk properly. They do let the "general public" who have very little idea about how to do it with a real machine make something that resembles coffee however.
Despite the crappy plastic case, this one seemed to be rather clever and well made. It's not clear why this one failed, but it was probably worth fixing if it was something simple.

[@zachburke8906]

Chris Robinson ima guess it makes coffee 200x better than what I have

[@SeanBZA]

Most likely it has not actually failed, probably just needed to be properly cleaned, though with those heaters they do not like poor quality water, so they can corrode on the inside and leave a deposit in the water of sloughed off aluminium oxides. Just taking the unit and cleaning the grinder area, the press side and stripping and degreasing the brew end would have made it work well again, getting rid of the most likely fault, poor tasting bitter coffee.
Sad though that these machines also have built into the menu system a self clean function, which simply runs through a brew cycle without sending any coffe beans through the grinder, ad also upping the temperature of the boiler slightly, so that the hot water and steam can clean the stainless steel filter mesh and the tubing of residue, though some also have an optional cleaning fluid ( basically a mild acid and detergent blend) that is placed in the water supply, and which then is run through in the clean cycle, before draining the tank and doing a half dozen rinse cycles to get it out.
At my local bank they have some Azoyken machines, and I tend to run the unit through a cleaning cycle before getting a coffee out of it, it does make a difference to the machine. The semi automatic machine I often ask for the operator to wash the head before using it, and dry it under the steam nozzle, so as to get the oils out. They did not believe that you can dismantle those heads to clean inside, and now bleach them nightly (new catering group) and they are actually metal colour, not dark brown in the nozzle. Coffee machine service guy I talked to says the most common faults are not cleaning the heads properly, and poor water filters, along with adjusting the temperatures too high, plus not cleaning the grinder regularly. Grind then use, not grind till it stops because the output hopper is full.

[@a5ync]

It doesn't count beans :) it detects when these are gone, to not to start making a coffee when there is not enough of beans.

[@martinkuliza]

Actually NO that's not the reason
been a professional coffee maker for 18 years
Look as the coffee beans as resistance or a resistor if you will or a load
yes the sensor sensors when there is no more coffee is in the plastic holder
NOTICE HOWEVER, THAT THE SENSOR ALLOWS FOR A CERTAIN AMOUNT OF COFFEE BEANS TO SIT IN THE GRINDING ELEMENT BENEATH IT
Now. if you completely empty the grinding element and turned the grinder ON, you fuck the gears.
look at like starting your car with no engine oil
so the sensor in a fully auto coffee machine is as safety so that the grinders gears don't fuck up , WHICH ARE EXPENSIVE TO REPLACE, that's what it's for
it's not to ensure that there is enough coffee to start making the next one coffee, although this is part of the reason, but certainly not the primary reason
it is also possible that the sensor measures 1 shot of coffee, although there is no question that it would cut off so as to not damage the metal gears
the reason for protecting the gears is that they have precise adjustments , down to a mm difference to adjust the fine or course setting of the ground coffee
AND AS EXTRA CREDIT POINTS
Just like Volts Amps and Ohms are directly proportional to each other
in a coffee machine
Amount of Coffee in the Basket
Amount of water pressure
Course or Fine grind
are also proportional
Example
le'ts just say the shot of the coffee is the same amount of grams EACH TIME, let's make it a constant
however, if the water pours for 35 seconds, and the coffee is ground FINE it should cause the coffee flow rate to pour a shot that takes exactly 22 seconds, which should pour 30ml of coffee
now given this, if you keep the amount of coffee the same
if you keep the water flow rate the same
but you make the coffee more course, YOU'RE GOING TO GET A BIGGER SHOT
but the main point is
IT WOULDN'T EXTRACT AS WELL
but, make it too fine AND IT BURNS THE COFFEE and you get nasty burnt tasting coffee
so it's about
Amount of coffee in the basket in grams
course of fineness of the grind
Temperature of the water
Flow rate of the water itself
the end resulting coffee shot should take 22 seconds to pour and produce a 30ml SINGLE SHOT,
double shots are different however
so as you can see, it's a very touchy feely kinda thing
and if you ever work in coffee and on your first day you change the grinder setting just to see what it'll do , DON'T BE SUPRISED IF THE BOSS BITES YOUR FUCKING HEAD OFF

[@martinkuliza]

@myVash1984
i know it doesn't count every bean
but if you notice... The sensor is located at the base of the plastic cone
and BELOW THAT CONE there is still room for some coffee beans to stay in the grinder teeth itself.
the point i was making was .... if the grinder teeth have no coffee to grind they get damaged
so the sensor is essentially cutting off while leaving coffee in the grinder teeth when there is a minimal amount
if it didn't do this , the grinder itself would not last too long

[@heyt54]

That solenoid is on/off, not variable.
One heater block in the boiler assembly provides water for brewing and feeding the second one which raises the temp and pressure for the steam wand.

Nahh Dave. The two separate boilers are both slightly different temps. One for steam for the milk frothing /steaming wand and one for the coffee. Coffee needs a lower temp. It burns if one uses boiling water, it needs be slightly less.
The pump should be capable of around 14 or 15 bar. It is only the resistance to flow from the ground coffee that creates the pressure. Hence the requirement for a correct grind and tamping into the Grouphead (the name young David couldn't think of). If the coffee is too course, the water will piss through without extracting all the coffee GOODNESS. If too tight it will clog and stall and pump will not be able to pump through.
David was quite a way off on a few bits and bats. For a Barrista. :-)

This was very informative.

today on eevblog, dave does his best little bitch impression. BEAN JUICE, IT'S GOOD FOR YA BOY, DRINK IT.

[@RonLaws]

Dave: The system takes water (not milk)
The 'Hopper' also makes up part of the filtering system; ground coffee beans are sent through the hopper to the filter, where it is met by the freshly boiled and pressurised water from one of the heater blocks which gives you the coffee then sent out the front (Used grinds sent to the waste tray in the back). The second heating block is for flash-boiling it to produce high pressure steam for the steamer nozzle.
As for the thermal cutout; the fuses likely serve as a last resort cut out in event the primary thermal cut out fails to disconnect.

[@wayneparris3439]

Sounds like you do have someone who knows about coffee. I am a COFFEE FREEK, I have ball park of $6000 U.S. on my coffee bar. What you have there is called a SUPER AUTO coffee machine. It is as David said, MEH at best, even the commercial SuperAutos in places like STARBUCKS (we call them CHARbucks for their burnt coffee beans) only offer MEH coffee at best. These machines will make several different coffee like drinks (coffee like due to the poor quality of the drink)
The dumpster is the right place for this machine but salvaging the parts is a close second!
The photo sensor is not to count beans, it tells the machine when you have run out of beans and shuts the machine off.
Uh, David, it is called a PortaFilter.
He is right with the beans, they go stale and need to be trashed about 1 month after ROASTING. Canned or bagged, uh are stale to start with.
This machine is not designed to be plumbed in so the container is for water ONLY. That is a vibratory pump, ... they work but are the lowest quality.
The brown assembly is to compress the coffee into the portafilter.
The adjustment on the grinder is to adjust how fine the grinds are. This is a low quality grinder, real low quality.
The heating block is as David said, it is a THERMOblock, lowest level of heating water, again bottom of the barrel. Dual stage, one for steam and one for coffee, they require different temps.
The block is called a 3 way valve, it diverts the water to the brew chamber, it does not regulate water flow at all.
2 thermocouples because you need 2 different temp. One for brewing which is 195 to 205 F which is below boiling and the other is for steam which of course is above boiling, typically about 260F
The water temp is CRITICAL for good coffee.
The wire insulation is for high heat protection.
No your lab does not smell like coffee, it smells like rank, stale and rotting old beans :P
Save the parts you can, toss the rest, that is the best use!
