Hello. I'm on my path to modding the Dedica and would like to have some advise from you please. Have you pulled shots after installing the dimmer and how did it go? Would you recommend installing a dimmer or rather mod/replace the OPV in order to get a pressure closer to 9bar ?
#Dedica, #Stilosa, #ecp, #GCP - they all out of the box provide an unbelievable easy way to reduce pressure)) Start main flow and also open a steam valve to control flow speed. It works!
Yes! Coffee meets engineering. Thats a niche i would like to see more of on youtube. And you are the guy for it. Please more videos of mods on cheaper machines such as these that are realistic to mod on.
I bought cheap one ($15) that connects to the outlet and provides another outlet to connect your lamp to. I pulled it apart and it had nice PCB inside with potentiometer. I'd say it's pretty compact and it'll be easy to repurpose. Last time I had my dedica apart, I remember there was some empty space at the bottom, so I'll probably try to drill a hole there. We'll see how it goes, and it should be much simpler to replace if it breaks.
Awesome, Tom! I installed a dimmer first on my Debica, inspired by your manometer mod. Then I installed the manometer as well! Starting this video and going to watch with interest! Mine are both “integrated“ in, with the manometer and a button (scroll wheel) showing on the left side of the machine. Looks almost stock! ❤
Hey, nice! Are you using a dimmer or a voltage regulator? I saw this video here where he uses a voltage regulator, and it also looks nice and clean: ua-cam.com/video/AqpqHcuFS0A/v-deo.html
@@TomsCoffeeCorner Hi Tom! Yes, Im using something very similar, although mine is smaller and I just fit it inside the machine and just drilled a small hole for the button to pass outside. And right next to that, I have the manometer, same as your installation. Wish I could share a picture, but UA-cam just deletes the comments if I add a link to a photo. :) I have been using that for about 3 weeks now, and have seen zero channeling as I start with a 3-4 bar preinfusion and as soon as the whole basket is covered with coffee I ramp up to as much pressure I want. You can also do 30 sek. blooming shots as well! Edit: my manometer is very stable, not fluctuating as his does on then video you shared. The regulator I have has 5kw capacity, and is on 220v 50hz.
Excellent video! I like that a grapgh of the voltage was provided. I wouldn't have expected less from an engineer :) I performed this on my Breville Barista Express and I use it to taper off pressure around 50% to 66% of the target yield. It results in a smoother shot and helps to accentuate the nuanced flavors of the bean. In a way, it mimicks the shot pulled from a lever machine.
I have seen people saying that after installing a dimmer on their espresso machine, they can make espresso with a much finer grind size compared to what they previously achieved without a dimmer. Is this logical? Thank you for the awesome content.
Hi, nice work. I am just wondering... Is this a better method than shortening the spring? Shouldn't we have a stable point knowing that we have 9bars and then adjust grind size etc? Using the dimmer and lowering the pressure we don't know if we low too much and have a coarse grind... Right?
I did try adjusting the internal spring, but that didn't work very well. I haven't found an OPV that I can adapt to the high pressure lines of the Dedica just yet...
@@TomsCoffeeCorner I was checking the Vibiemme Dombar adjustable OPV 1/8 male/female coupled with a Jura membrane pressure regulator, but I have to check if it fits inside the dedica
Hi! Your diagram is wrong. Voltage in the socket is from 320V to -320V. The 230V value is an effective voltage also known as RMS and it is not a peak of voltage.
Awesome Tom, I have watched almost all your videos. I have a DeLonghi EC220, I guess it's similar to the insides of the Stilosa, do you think that this cheap machine worth the pain to do this hack ?
It seems that I overcomplicated my dimmer implementation, I used a solid state voltage regulator controlled via a signal generator, I would love to share it with you and know your thoughts. I did choose this because of voltage spikes in the circuit due the pump being a inductive load.
@@DaddyMakesCoffee that was my first and foremost reason to do it this way, but It ended being a cumbersome implementation. Maybe I had the skills to make 3d models to print I would have made something better. I'll upload a video maybe.
@@TomsCoffeeCorner sure, here is a short video of the mod in action, If you want to know more about the internals, I would be more than happy to share my findings. ua-cam.com/users/shortsaXPC1pJ50DQ?si=5k0QuLu76EeF5cJr
Hi Tom, I want to buy a dedica, is It for you a good choice or you recomend other option ? I already have a grinder so I dont need a super automatic machine Thanks for your videos , It is helping me a lot
For its price range, yes I would recommend it. It really depends on your market though. I have heard these are really expensive in some markets, like South America, Asia, etc.
@@TomsCoffeeCorner thank you Tom, It is about 150$ here. And I want to buy also the bottomless porta filter, I learned that watching your videos Have you tried other brand named "cecotec" ? It is cheap , but I think is less durable
Hi Tom I think I asked you this question before but would like to ask your recommendation on De'Longhi La Specialista Arte, Bean To Cup Coffee Machine, EC9155.MB. Or the sage barista espresso bean to cup. Thank you.
Tom, what dimmer switch would you recommend for me to buy for my EC885? I have a US model. Also, I'm trying to search for the manometer parts here in the US, and it's been a mission. If you have any suggestions on that, please let me know. TIA
Sorry, but I don't have a USA parts list. I know they're hard to find. Maybe someone else can chime in here? Same with the dimmer - you just have to search for one to your liking. Should be a simple one (not with a chip on board), and able to handle the wattage of the pump circuit.
Hello Tom, I have a problem with my portafilter it keeps slipping out because of pressure and eventually making a mess. I don't know what the problem is exactly?! I'm also talking about a dedica.
Hi, Tom! Great Video as always Could you help me? I've bought a bottomles portafilter to my EC785 and it makes burnt and bitter caffee with zero crema and actually it's extremly hot. I use fresh beans but somehow it does not want to work :( Thx for your help!
Can u lower the Bar pressure as to make a good coffee good to lower these machines some have a control most machines do not a very good tool they all need
Interesting idea. Guess the same result can be achieved by a 5 euro ac engine speed controller. But most important. Did it improve the taste of the coffee?
great and thx a lot again and again.. one more fine mod - you already did this with an external Dimmer for the Dedica - here another similar (alternative) solution (in German), using a small(er) and perhaps cheaper voltage regulator : ua-cam.com/video/AqpqHcuFS0A/v-deo.html ,
Well, that remains to be seen. I don't know whether it will have an effect on the longevity. Essentially, truncating the time the pump gets voltage should just reduce the current that flows through it, but I don't know for sure. I think there are others that have had dimmers installed for quite some time without issue. Feel free to chime in with results, anyone. Cheers!
Infact the dimmer, simple as you mention which worked finally for you, is a potentiometer effecting voltage. We learnec at circuit 1 unit, V=R×I. Which means voltage and current will drop down as a result of higher resistance. That will affect pump in long run.
@@DaddyMakesCoffee as I’ve understood, you need to use a dimmer because a potentiometer won’t work for this pump (might have to do with staying over the voltage threshold). But that’s just what I’ve read, I haven’t tried it myself. That being said, a dimmer operates differently than a potentiometer. I wish I had a scope, so that I could check out the Signal.
Absolutely the dimmer is not equal to pot. I meant analog diammer which is pot base works. The first one, 100€ you bought, is digital dimmer. Because of that it didn't work. The triac used in analog pot base dimmer though cuts the AC sine wave signal, which cuts it into discrete sections, leading to well customized lower voltage output. Therefore, pump works on lower voltage anyway.
Thanks for watching, comments welcome!
Can you test Crm 3605 coffee machine please, I'm thinking to getting it.
Would you say the lowest 50% dimmer setting you talk about in your video, is equivalent to 9bars?

Hi tom. Can i put dimmer alone? I cant find manometer parts here in amazon uae.
next week ,Tom will be fitting a portable lcd tv and a radio,plus a can opener to a Dedica lol :P
😅😅🙋🏼♂️
Gaggiuino version for Delonghi. Why not Tom 😊
We definitely need a knife sharpener ✌
This machine is like a toy ,it gets so many customizations. You 've got to love the Dedica 🙂
Delonghi should hire Tom under their R&D department.. 💪💪

The Dedica master strikes again 👍🏾great video.
It seems that the combination of Manometer and Dimmer helps to adjust the pressure and keep it always at its correct range 🤩🤩🤩
I'd like to play with this but would never try it on my 3630.
Totally fascinating video
Omg, that is soo crafty...easy knowing you're an engineer..well done 😁👍🏼👍🏼

Haha, love your videos! Next step: a Diesel engine for a smoother extraction :D
Hi Tom, thanks for this. It would’ve been nice if you shared the measured portafilter pressure at different dimmer settings
That's true. Maybe I'll have to put the manometer back in and measure. Thanks for the feedback! Tom

Lol, thanks for the feedback! The K6 is nice! Cheers, Tom
Cool. I'd really like to do this but with some kind of smart dimmer to set up flow control curves instead of doing it manually, really dial it in.
Hi, nice work. I am just wondering... Is this a better method than shortening the spring? Shouldn't we have a stable point knowing that we have 9bars and then adjust grind size etc? Using the dimmer and lowering the pressure we don't know if we low too much and have a coarse grind... Right?
Why don't we just replace the spring in the pressure valve to decrease the browing pressure ?
this is some absolute nasa-shit! I love it!

From such a change in the sinusoid - will the pump be damaged?
Hi Tom! I really like your videos. Did you try modding the Dedica with an adjustable OPV (Saeco maybe) and with a pressure regulator(Jura maybe)? Tya

Showing your age now video tape lol interesting video, it’s just a pain taking it apart
Thanks for complete description. Is this mod replaces pressure valve's mod you presented some time ago? To make water flow slower...
Yes, I'd recommend this. The OPV is not really adjustable in my opinion.
Awesome Tom, I have watched almost all your videos. I have a DeLonghi EC220, I guess it's similar to the insides of the Stilosa, do you think that this cheap machine worth the pain to do this hack ?

That's the safest way of controlling pump power rather than dimmer only. Longevity wise I am speaking.

Maybe you're grinding too fine? Otherwise, if you're using an aftermarket PF, it might not have just the right fit.

Hi Tom. Any idea on how to fix my issue? The steam wand on my Dedica started to drip water while I brew espresso.
It could be that the steam valve is becoming leaky, a not unusual thing for espresso machines. Have you recently descaled?
@@TomsCoffeeCorner yes, I’ve recently descaled. It’s never done this for years and now just happening. I upgraded the wand over a year ago.

It can, yes. I think in some cases it can smooth the shot out, and make it more balanced. But really it's more for experimenting.
