You forgot to clean the ball ventile inside the plunger of the brewing unit. There is circular cap in the plunger that looks like it it is forming a cross with a little dot in the middle. It is housing a spring loaded ball ventile. You see it at 2 o'clock (or North-East however you want to see it) in the frames around 4:00. You can carefully turn that cap, e.g. with a knife or big slit screw driver. It isn't threaded or anything, but with each rotation the spring will slowing push the circular cap out. When not cleaned regularly, the spring, the chamber and exit to the side of the plunger can get clogged and the ball ventile can get stuck or will have hard time moving once it is all gunked up, e.g. when the mashine isn't used regularly. Be careful though, the small parts can easily be lost. You are welcome.

this video saved my machine. I was ready to get rid of it but after deep clean its working again. Thanks for the video

Absolutely brilliant, thank you. Great camera work. Saved to favourites.

Thanks! I had problems to get the part back in the brewer, but figured out I had to unplug power at a specific time

Thanks for your effort! It helps a lot... I have the exact same coffee machine and today I'm doing this 🙌

Dude you are an artist!

BIG THANKS PAL! You're awesome, so helpful 🙏🏻

Great vid in silence but so loudy with its quality : thank you very much

Nice video I thought, most intuitive. Thank you.

Aah a quality video without crappy music. Nice one dude!

Great Great video! Specially the first tip. I didn't realize you can have all that cleareance to lubricate the bar by using this method. I was worried to unmount some parts.

Great video. Exactly what I needed. Thank you very much :)

Super Video - Klasse gemacht / great tutorial to maintain the units in advance

Magnificent work!

Thanks for helping me to find the parts I need.

Pominięty został tylko zaworek do pianki.. Świetny film pozdrawiam!

Thank you very much for your effort 😊👍

every time i see internal parts and mechanism i can tell this is good design.

Watched this then changed the O rings, thanks.

Super Tuto! Merci!

Thank you for this good video ! I have a small remark concerning the cleaning of the brewing unit. It is written on the unit in capital letters "rinse with water only. No detergent". I don't know exactly why but when designers write such warnings I prefer to respect it.

Thank you helped me out great

thank you so much, this is importatn for me.

Thanks for de detailed documentary. One thing you forgot, to clean/replace the pressurevalve (04:45:00) in the brewunit.

Sehr schönes Video👌

Thank you so much!!!

Great helpfull video!!

The actual engineering in this is super interesting. Saeco/Philips brew group have much more part with thinner plastic, my bet is this solution from Delonghi is more robust with less moving parts and a more solid case. I was looking those maintenance videos to help me decide on which machine will age better and is easier to service by myself and I'm now convinced I'll probably go for a Delonghi. Thanks myworks ;)

Thank you friend.... 👍

Great video as always! There is one area that needs to be cleaned which is not often talked about - the spout assembly or even the door assembly. There can be a lot of espresso drips and leaks that are trapped and accumulated over time, in the adjustable spout, or in the hollow door panel of some Delonghi models. The normal hot water rinse bursts don't do the trick and cannot dislodge the build up. Second to disassemble the entire thing, I find that espresso cleaning tablets (not descaler), dropped into the manual coffee doser followed by a couple of rinse cycles will help keep the area clean. The descaler doesn't seem to breakdown those build up. Plus, on models with descaling function, the descaling is done through the hot water dispenser, so it doesn't get a chance to rinse through the spout. You'd be surprise the kind of mildew/mold coffee residue slime that can be flushed out that way - it's down right nasty. I have been tweaking the method and found that if break those tablets into 3 equal pieces and do 3 consecutive cleaning rinses, I can flush out most of the build up. I own several Delonghi and Saeco superautos and while very easy to make drinks, proper maintenance of these machines are overwhelming. Delonghi is particularly worse than other brands due to their design choices not favoring cleaning. There are just way too many parts needs to be cleaned or kept clean in order to have nice coffee and "clean/healthy" coffee while maintaining longevity of the machine.

Limpide , merci 👌 . 👏👏👏👏👏👏

great, thanks

Top, the tips to access the spindle....

Excellent merci.

can i use WD-40 instead of this grease ? because i couldn't find one locally

Excellent

Thanks for this vdeo 👍

Bonne vidéo, well done

I can’t stress this enough! Make sure the gears are lined up perfectly. Mine looked close but were apparently off a little bit. So, when using it it made the loudest popping sound. I thought it was broken. Make sure those are lined up. Luckily, I think mine survived, but do not take that chance.

Do the descale before the through manual clean & lube..... (those acids may reduce the grease effect)

Thank you for yet another detailed video on delonghi maintenance. Wonder if you help me find a substitute of the grease model OKS 470 (white grease) that you used to lubricate the brew unit screw shaft? I live in the UAE and unfortunately I'm unable to procure exact one locally. I appreciate your response. Keep good work and best regards!

Nice work! For greasing the transmision, after I take out the infuser, run it 6 seconds, unplug the device to have a better access but after that it will automatically come back in place? Thx

Thankyou....

I have saved your video for later use, as my unit is brand new, so I appreciate the detail of your videos. I have the De'Longhi ECAM35075SI Dinamica. I’ve noticed that when I turn the coffee maker on or off and the machine goes through the start up or shut down procedure, water also drips into the tray from the left, front, inside of the unit. This water is in addition to water being dispensed from the coffee spouts in the rinsing process (I catch this ‘rinsing water’ in a cup). I brought this to the attention of De’Longhi for warranty purposes and they had me take pictures and then had me send my unit in for repair. I received it back from their repair shop and they said that was normal. My question is whether this is normal or not? Thank you very much for sharing your knowledge base.

Hi brother, I just got my first coffee machine (second hand) and the model is exactly the same. There is also water in piston. I searched whole Internet and your video is the most helpful one. Thank you and now I am pretty confident to do if myself. Hi brother, I just got my first coffee machine and the model is exactly the same. Just one question (appreciated if I could have your clarification --- I counted there are 14 o-ring on the table before you assemble the piston, but the video only shows the size for 13 o-ring, I can not find the size of the o-ring in the very left (I believe this one is appeared at 5:18 of the video). Would you please help to give the information about this one? Thanks.

Fantastic video, looks like the same or very similar brew unit for my ECAM45.760.W that's squeeking whilst dispensing probably needs a clean and lube or just lube. I feel much more confident having looked at this.

Thanks!! Where did you get the O rings?

Amazing video - thank you, it's great to have my Magnifica S cleaned back to (almost) factory shape!!

Love silent films!

6.14 make sure the small, soft plastic, triangular pad is correctly mounted just in front of the screw near the word WASSER, that's near the red catches.

Thank you for this video! Is this a way to repair a machine that only gives half cups of coffee or sometimes no coffee at all? I noticed the two geared levers are very hard to turn to move the piston.

Thank you for your video. I would like to know what size o-rings are needed for the brewing unit?

The piston head. The small valve on the face of the piston can be removed to clean out the channel to the side of the piston. Another method to clean the channel is to push the head of the valve down, use a very small blunt tool, then force water into the small hole in the side of the piston. Not as good as removing the valve but you won't lose the tiny spring. To lubricate the O-rings use a food grease only. If it doesn't say "food compatible" on the pack DO NOT USE.

Great video thank you. Does it matter if you use OKS 1110 grease on the spindle (0:46) on video

Hello @myworks, You make very beautiful videos and I thank you for it. I own the Delonghi Magnifica S but I've had a problem for some time now, the machine won't turn on. When I turn on the power, the LEDs light up well and then go out. Nothing happens when I press ON. Only two LEDs light up when I remove the water tank and the coffee grounds container. I thought the problem was with the power board as there was a strange trace, the machine started up and was functional again and then broke down again. Would it be possible to give me a lead to repair the machine please?

you forgot to clean the valve and the channel inside the piston , under the metal screen. That has a major impact on creaminess of the espresso. And it is better to use an alcaline solution instead of dish soap.

Thanks for the video, I found it very useful.I have Magnifica Ecam 22.110.SB and the coffe is like water I tryed diffent kind of setting rotating the knob but the result is always the same, watery coffe :( . I can ear the machine don't put much pressure on the coffe at all. Any suggestions. There are any extra seting where I can fix this? Thanks

Super

Perfect video, exactly what I needed. Thanks.

Hi great video again, just curious, wouldn't the grease on the O rings collect the ground coffees and get stuck?

Great video I thank you how often would you recommend doing this?

Any alternative grease to the OKS 470 which I can use? I cannot seem to find this type of grease in small quantities. Thanks for the video!

Great video. Have some water coming from under the machine, on the left. Is it because brewing unit seals are old?

Hi, thanks for the video. Where can we buy the O rings for replacement?

Excellent and informative...I have this machine and recently been getting Install Infuser Assembly error. I keep tricking the machine into working again but I would much rather repair the issue. Any tips?

Thank you for this video! Question: I found a very small black rubber thing shaped like a triangle. I saw that in your video too at 3:36 (in between the red push buttons, right below the spring, it's sitting there) and again on 4:03 (a small black object under the water, next to your brush and it stayed there for a few more seconds). It was not shown in your video where that part is supposed to go and I cannot figure it out myself. Any ideas/advise? Thanks!

Hi, great video, but I'm confused about the greases - you have linked 2 types. Which one goes on the piston seals? In the video you are showing a pictogram "food safe" but I don't see it either of those links.

Hola, me gustaría saber el difusor de mi cafetera delonghi no retrocede la palanca para quitar el café sobrante y cuando la apagas no baja la palanca hacia abajo del todo.. Muchas gracias por tus videos, saludos desde España

Hello, and thank you for this video. We have an identical machine. How OFTEN are you doing this cleaning? Do you judge it by sound, Taste, or time?

Brilliant could ypu tell me ifi can take the coffee nozzels apart as they keep blocking pls

Danke für das video!Sehr hilfreich und super qualität!Ich versuche auch selber reparieren und reinigen...bei mir ist das wasser geht zu langsam durch,auch nach die entkalkung,kann irgendwo eine verstopfung sein Mfg:Z

Thank you for your clear informative videos, they are brilliant! Quick point regarding this video, when cleaning the piston in the brew group, you left the clear amber coloured crema piece in place, I often find this to be gunky and in need of a good soak, removing it allows the piston/plunger to be cleaned through the hole where it was situated. Going on to your grinder disassembly video now, my grinder sounds rather clunky and the grind adjustment is on the finest setting to get a decent shot out. Is there room for adjustment on these by pulling out the piece which limits the setting and bringing it back a few notches to go finer? I don't know anyone who has their setting all the way down to the course setting, seems pointless. Thanks again!

Can you help with replacing the steam knob? I have got a new one and read I can just pull out the broken one and push the new one in but it doesn't want to lock in. There is a spring/split ring on the end that seems to be stopping it.

Great video. I’ve just acquired a used unit and was having a look at the seals on the brewing unit as per tip No2. In taking it apart, a small triangular shaped rubber fell out from somewhere on the unit. Can you tell me where this goes as it’s not clear in the video. Keep up the great videos ,

Thank you very much for your videos, it helped a lot. I use lactic acid for descaling. According to the composition of the original recommended descaling agent, this acid is used. What do you think about it? It is a liquid form in a concentration of 80%, which I dilute to 25-50% (composition of the original descaling agent). Of course, lactic acid (1L/7.30€) costs a fraction of what the original descaler (0,5L/11€) - in Czech Republic . My coffee maker is DeLonghi Magnifica 23.210B

Thank you for your video. How often should I perform these maintenances?

Nice video, where do you get the replacement parts ? Ebay ? Do you have any service manual ? Error codes etc ?

Hi :-). Great video! I’d like to know what you do after greasing the transmission? Do you simply turn the machine back on, and it then goes back to the correct state? Thanks in advance 👍.

How did you lubricate the brewing unit seals? What lubricant did you use?

What are the most important maintenance tips for Jura E6 coffee machine? Thank you🇺🇸

Note the rubber seal at the top of the left part at 6:13 It came off during wash for me, believe it was on the right hand part here., and I had no clue where it was supposed to be :D There are some diagrams online as well which show all the parts. On my machine the (not sure what it is in English (hubs? / the mounting pin and hole)) for the cogwheel / arms was greased well as well.

❌❌⭕⭕ Hello, this video is interesting and helpful. Unfortunately in my opinion something is missing. There is another large o-ring in the machine located where the extraction group gets pressed upward. In my case it was causing squeaks. To access it you must let the carriage go down and then remove the electrical plug for safety because the leadscrew is very powerful. Good luck.

Ok now having disassembled , cleaned, lubed and reassembled my brew unit I can confirm there is a small piece missing focus from this video (as it is there if you watch closely, it is visible at 6:29), which for me at least turned out to be a bit crucial. When you take it apart a small black piece of rubber with a groove will fall out and its not entirely obvious where it came from. If you look at the unit with the piston, and by the screw hole there is a bit of plastic that juts out with a small notch above it, seat the rubber gasket on that bit jutting out so the top sits on the notch above the surface. Now take the other side and assemble just as shown in this video, you will notice a small piece of plastic covers it, looks like it compresses it. This was necessary for my unit to fit back together snugly and ensure smooth operation, I am not an expert but another thing that wasn't obvious to me was when you look in the piston shaft you will see a little pinhole in the bottom, align the piston (which has a pin that goes in that hole) with that. Thank you @myworks for the excellent video, there is no tech manual easily found for this and these sorts of maintenance instructions should really be in the manual for the product. Lubrication for mechanical parts it important, you should not really need to have the machine serviced professionally to do these sorts of things so once again thanks so much. Your work is appreciated.

Thank you very much, I have learned a lot by watching some of your videos. I wanted to ask you about a problem that I have in my magnifica S 22.110b. It has 2 years of use. In every coffee I make, a little water comes out of the frother (cappuccino maker). The coffees often come out with little quantity, and I think they no longer come out with the same pressure as at the beginning. I have noticed that sometimes it takes an extra second for the coffee to come out since the pump starts to make noise. I'm thinking of changing the gaskets, but I don't know if it could be a pressure relief valve or something. thanks for your time, greetings.

Do you know how easy it is to replace the 'Control Level Regulator' on a Magnifica S ECAM22.110.B please?

nice video !!!! how often you recommend doing this cleaning and which pills do you recommend?

Great job. Just wondering where I can order those O rings?.

Hi, kann es sein das die Firma OKS irgendwas an deren Fetten geändert hat? Es fehlt mittlerweile das Symbol für Lebensmittelsicherheit?

My machine won't function on the preground setting, it works on beans but appears to just drop the preground into the tray at the bottom. It had the light on for a descale so I did that and the light still doesn't reset so I assume this has got something to do with that, I'm a gas engineer/plumber by trade so figure I could probably give fixing this a go. Is it necessary that I strip and clean everything, it probably needs it anyway, can you direct me to a seal kit that I may need if I go ahead and do that? I have a msgnifica S but it's the 4 horizontal button arrangement with dial in the centre below the buttons.. TIA

Thank you for the video. I have a question. Last 2 days water goes really slow when making the coffee.(drop by drop) Machine was always on same grind settings from first day so I think it is not that. Any advice. Sorry for bad english

What does it mean when water comes out clear from frother, but black/brown floaty bits in the water from coffee outlet spouts?

Hi, thanks for the informative video. When I took mine apart a small piece of rubber came out also. Any idea where this goes? Thanks... EDIT: Nevermind I saw it at 6:14

Hello, can I pick your brain with couple of issues: -often the piston of the infuser doesnt travel all the way and the puk is not ejected and get stuck there which is a problem when u do your next coffee. I have put some grease on the transmission and on the piston after doing a clean up as shown on your vid, but it doesnt slide easily compared to a brand new infuser. Another problem im recently having is just after grinding the bean I hear a wind noise as if the air pressure suddenly dropped and the coffee is very watery/light, the puk is very thin although it grinded the beans for 7-8 seconds, and there is water in the puk container.

Hi,when I use the pre ground coffee function and then add the coffee and press the Cup button it starts up but then gives the error where it's says no preground coffee added. Any ideas what's wrong or some thing I am doing wrong?

The model I am using is the DeLonghi Primadonna ESAM6600. The brewer piston sometimes does not go down, so the brewing process is in progress and the coffee powder falls down. Why is this happening? Is there not enough grease?

how do I make the espresso with grease on top again? When the machine is new, same coffee bean with not too fine grinding, the espresso was very intense and lots of grease on top. But now, the espresso is weak. Do you have any recommendations?

Excellent tips. Help needs: please advice how to fix watery coffee problem! The machine runs fine but coffee is not as good as before. Thanks in advance.

wait, do you use the same OKS 470 silicon grease to lubricate the o-rings and spindle?

Hallo. Danke für das Video. Kann man auch bei DeLonghi ECAM 28.466.MB Getriebe schmieren wie in diesem Video gezeigt wurde?
