Here is an easier way to temp surf on the Dedica: kzfaq.info8GO1b94CgN4

Dear Tom! Temperature hack is the very best hack ever! It really change my life & my coffes. If you can find a way to tweak temp sensors or anything else to reach 94°C at shower would be nobel prize for you...mean time ur hack it's the fundamental trick I found all over the web. Congrats & keep trying!!! Tks again.

This man sure knows his stuff and is a great teacher-- I bet he is some kind of ENGINEER, that he is so precise with all his teachings. We are pretty lucky to get this information for free, really 😄

Glad you got around too this! It’s nice to know the actual numbers so you can get a better gauge on what method to use for each roast. I noticed that in darker roasts I preferred to use no extra heat and even sometimes a cold portafilter to remove almost all bitterness

Well done! Thanks for your efforts on Dedica! I watched all your videos they're helpful to those who have it, and then I think I could done it better now! I'll give this heck a shot!

This is my first machine and your channel really helped with finding the right settings and tools for the best shots. Thank you!

I've been looking for a long time for temperature hack on Delonghi. Thanks a lot!

i have the machine a week or so... and the first 3 days i know this... but with this video i can "know" for truth :) thanks (all your videos are great, and be "a must see" to everyone who has a dedica machine. greetings

Hello Tom! Great video, great hack. I like Delonghi Dedika. Thanks for your time and your job!

Another awesome video. Always one more way to get the maximum of our Dedica. Thanks!

Very nice! I'd absolutley love to see a video like this but for the breville thermojet products. (bambino/barista pro) Would be interesting to see which temperature surfing routine results in thr most stable temperature and the best actual average temperature, as there's alot of conflicting information. Preheating with the pressurised portafilter, running a cooling flush, running the stream wand first, cold vs hot portafilter (breville actually recommends cold over hot after kaffeemacher's tests) etc.

Steam hack seems to be quite dangerous because of temperature rise up to 98 degrees that might burn your coffee. If did recently similar measurements, and got a bit Higher temperatures. I guees that different termometers will give you different results. But, anaway, Tom, you are one of the greatest ec685 ambassadors in this world!)

My favourite channel for Dedica optimization and I'm really happy to have found it. Many many thanks for this valuable hint, Tom. Appreciate all your effort for this machine;-) Will try the hacks by turning the machine off/on and the other variant by starting the steam functionality just for 3 secs..

Very very good video, still have to watch it in full length but just seeing how you pull your shots gives me confidence. That I discovered a great channel! Greetings from Germany.

I am always doing the kind of temperatur surfing suggested by the guys from Kaffeemacher. Start and stop pre infusion twice, wait for a minute and then pull the shot

Thank you for your very informative channel. If it wasn't for your channel I would have sent this machine back because I wasn't finding good info on the Dedica. I can't thank you enough.

It works and and that is also necessary. The coffee didn’t come out hot enough with the normal settings and I wanted to send the device back - until I tested your hack ;-)☕🎆

Great video Tom . Thank you 👍

I'm going to try the hack tomorrow morning!!

Great Video 👍, Tom. I used to pour in hot water in the machine EC685 for keeping the temperature around 90 °C, I can use your hack method now.

What hasn't been said is your temp mode setting during the final, 'hack' test. Was the machine pre-set to 'high' or 'medium'?

Was time to see some hack on Dedica 👍

Hi Tom, have recently purchased a Dedica with bottomless portafilter and Sage Smart Grinder Pro combo after watching all of your videos. Found something that might be of interest for a future video in terms of temperature surfing. If you press the steam wand button then wait till solidly lit, as if you were going to steam, then switch the machine off at the wall and back on, it will no longer do a flashing cool down if you ask it to pull a shot. Instead it will pull a full temp shot. Maybe you could do a temperature test to see if it is too hot or good at this temp? Anyway, thanks for the time and effort you put into your videos.

I already use this hack with my Delonghi ecp withowt turn off (it alow) result IS perfect nice crema color less acidity

You really know how to make the Dedica shine! The water coming out of my DeLonghi La Specialista seems to be at 191f with no coffee in the PF. The hack does not change this. My manual says at one point that you can set custom temperatures beyond LMH, but does not explain how. Really, all the espresso machine has to do is present water to the PF at a specified temperature and pressure and stop after a predefined amount of water has passed through the PF. The thing that boggles my mind is that many machines have lots of bells and whistles but do not perform this basic function reliably, instead hacking around how the pump alone performs to poorly approximate this with such hacks as a poorly calibrated OPV that dumps hot water back into the water reservoir.

Another great video, Tom! I believe this technique is called temperature surfing for those looking for more information about it. What’s that beautiful machine to the left of the Dedica by the way?

Yes I've done this many times myself. I'm just afraid that it's too hot for espresso. You can tell it's hot by the steam it produces. It looks like that it's as hot as it should be.

Great video Tom as always! I am wondering if you compare the taste of the shots? Would you recommend a high temp or the temp hack for medium roast coffee?

I would add that one of the most important things for a good extraction is water flow thermal stability on contact with a puck. All prosumer machines maintain a constant temperature of their group head. With Dedica you can do it by preheating its group head ahead of time. How do you do it? I found a hack of keeping dripping water in your portalfilter for 5-7 minutes by placing a puck screen inside an empty portalfilter. If you want to make a video on this one, don't forget to mention me! 😜

really helpful - thanks!

Hey Tom, great Video. One question: The last shot with steam hack: at what temperature mode was your dedica ? Was it at high?

Hi Tom good to see you tested the temp hack idea, well done!! I see the temp starting the extraction is quite high, should be around 92 degrees for medium roast coffee. Maybe waiting a number of blinking the steam button and then stop it could control better the desired temp value. I also notice the starting PF temp is higher in the hack test probably due to the previous tests and that could contribute to the high peak starting the extraction. I do not have a probe to insert to the PB so my option is to test based on taste, but for sure are very helpful the graphs in the video!!!

Good morning Tom. Interesting video that disproves the generalised statements of "die Kaffeemacher" about temperature surfing. I have also noticed that the settings of the two lower temperature levels are usually very acidic. About the methodology: 1. Did you make at least one empty brew before starting coffeebrewing? The start temperatures are only half as high as those of "die Kaffeemacher"! 2. An additional idea would be to flush the first 2-3 seconds before brewing in order to transport the cooler water out of the pipes. Then the brewing could be more even. Can you perhaps measure this again with empty brewing and flushing? A small constructive criticism: The axis scaling is not so well chosen. But still a great video. 👍

I still cannot get near the 197-205F (90-96C) recommended range even with the hack. My electronic thermometer shows 158 at the highest setting, measuring the water in the cup as it is coming out. I see you got up to 98 before the hack. Something is probably wrong with my machine.

Great video as always Tom, I was really interested in some temp profiling with the Dedica. I will definitely try this and check the improvements of my espresso as I typically use medium/medium-light roasts and it tends to be a little sour, hopefully, the temperature hack will solve the issue.

thank you

Well, you don't have to went through the trouble to get higher temperature, press the steam bottom, let it blinks for 3times and cancel it, you should be able to get up to 92c for that.

Hi Tom. When you apply the hack at the end of the video what is the temperature setting of the machine itself? Medium? High? Thanks

Hi Tom, thanks for your video. I would like to understand why when I remove the portafilter, I often find the coffee wet on the surface, sometimes even some water. Thank you so much!

I was not sure to get this or the Bambino, but the amount of hacks and such on your channels really shows the extra money isn't worth it!

Awesome this is what I was looking for. 1 question, how much have you waited after changing the temp on each time?

Great video. What coffe you use?

Hello Tom, really great video! I will definitely try it on my Dedica to see the difference that makes in taste. I have a weird idea that you may find interesting/worthy to try: In a previous video you mentioned that the thermoblock is far away from the group head, thus the temperature instability. If we somehow replace the plastic water tube with a metal one (that retains heat better than plastic) could it improve the stability?

we r waiting to upload a video with a 9 bar standar fix spring for the 9 bar mod.

I don't understand. The single cup and double cup icons means heat? Sorry if I missed the explanation.

Hey Tom, curious..what would happen if I fill the water tank with high temp water instead of normal water? Would that not automatically result in high temp extraction?

Give the Delonghi ecp 35.31 a better shot then the dedica? In temperature

I use this machine too. Unfortunately i dont have better grinder for it so if i use my grinder, and use 15-17 g of bean it pulls sooo fast (like only 10-12 sec without preheating) and i can’t grind any finer. Any suggestion what to do? And i temp it as hard as i can but still i can’t make the flow slower. Because my pull always so acidic, i’m at loss now, i only ever got it right once somehow smh…

Is the hack safe for the machine? I just bought one

i noticed it bubbles at the end when the water is too hot?

Temp hack should be done on which temp mode??? Lo, med or high??

Hi Tom, can you please advise how to clean a clogged shower head for the Dedica?

What is the default setting from the factory, medium?

I got a Kottea CK150S two weeks ago and so far I've been pulling espressos that taste a bit acid and sour, not on the first sip but in the last 2/3 sips. I suspect that pulling at a too low temperature can be the problem of the bad taste so I tried the hack from this video. By doing this hack I can feel like the water is hotter but I´m still not sure if it´s enough. I mean, I´m able to take sips as soon as I pull the espresso, it´s not that hot that I need to wait before I start to sip. How is it for your machines? Do you need to wait for the espresso to cool a little bit before you take a sip?

Hi Tom, I'm interested to your WDT tools which can stick to coffee machine. May I ask where did you buy?

Hi Tom! Seems like brewing temperature stability is not Dedica’s strongest side :-) I wonder how stable is the brewing temperature of the boiler coffee machine. Did you compare it to your Gaggia Classic?

What temperature would you suggest to use? High?

Hi. I have been using this machine for many months and have been getting nothing but sour shots from it, no matter what I do. I don't have the same tools to measure but the hottest temp I could get out was around 75C on the hottest setting. Could the machine just be faulty?

When doing the hack are you on the highest temp mode?

Привет, Том! Скажи, ты рекомендуешь выставлять максимальную температуру, а затем включать пар для нагрева и затем готовить кофе? Всегда? Или это зависит от сорта и обжарки зерна??

Why not measure the temperature as it fills the shot glass? The thought of that probe wire crushing the seal hurts my head. 🙂

Is it me or what ? - the normal med temp was lower than the normal low temp and the hacked higher temp was lower than the normal high temp - so the results are really crazy here

I didn't know that I was hacking I would make Steam milk then shut the machine off and then on lol

What handle are you using?

That is not the proper hack. In order to obtain the proper temperature you have to first run a blank shot with the empty portafilter in. After that, immediately press again the double shot button and let it run only for the length of the preinfusion. Then when it pauses stop it. Then repeat the last step and wait about 1 min before brewing. That is how you obtain the perfect temperature. Take a look here for the measurements: kzfaq.info/get/bejne/g9CqqM2Z2su8gXU.html

Stop doing that and get a nice 58mm portafilter machine ;)

What kind of coffee you are using for this mashine? I mean how fine is it?
