Thank You

Welcome my friend!

[@mikeowen000]

New owner of a DF54 here. Very helpful video! Thanks!

[@Thetache]

I think you are right on user error I have had my DF54 for months with daily use for both espresso and pourover and never had one incidence of choking or clogging, the de-ioniser needs a tiny artists paintbrush up the chute to clean off the prongs after 2 or 3 uses to keep static under control. retention is always sub 0.2g and anyone thinking of getting this DO IT, I also have a NIche Zero for 2 years and use both daily as I like to compare conical and flat burr coffee profiles.

[@gert-janmartens9555]

What are the differences between the conical and flat burrs, in terms of flavour?

[@Thetache]

@@gert-janmartens9555 Much more clarity and pronounced acidity from the flats in a pourover and espresso. more body and texture from the conicals in espresso

[@Thetache]

@@gert-janmartens9555 Pretty much as the legends say, more clarity and higher acidity from the DF54, more body and more balanced from the Niche but less clarity in the flavours. I prefer a straight espresso from the Niche but if Im doing a milk drink the DF54 espresso cuts through the milk better. Pourover I like the Niche more as I am not a big acidity fan. But you can get the coffee you like from either by tweaking recipes.

Thank you this really helped

Glad the video helps you

Thank you so much CY. I followed your video and managed to make my DF54 work again. You mentioned you never had any problem with your DF54 and you mentioned it's user problem. Could you share with us the correct way to use and clean it in order to avoid it suddenly stop grinding? Thank you.

Top tip: placing the rim back at 35 and then turning seems to do the trick.

[@surfacepro5519]

Doesn't the chirping that happens when you align the zero point damage the burrs ? Sounds like they are grinding against each other.

[@CaffeMartellaSingapore]

The part that is causing the chirping does not involve in the grinding for the espresso burrs and the outer rim of the burrs are flat. Besides, the touching is only briefly and hence it's all right.

[@thehoelzels6316]

You need to weigh the beans with water sprayed. It will change the final weight otherwise

[@ThomasPancoast]

This was a very helpful video. Is it really OK to grind to the zero point while it's running?

[@CaffeMartellaSingapore]

A gentle touch between the burrs is fine as long as it's not rubbing each other for a prolonged period of time and the sound when the burrs touches should be just chirping and not screeching.

[@oats5218]

Wondering if this is a common problem with DF54? Was thinking of getting this, slightly worried, and am wondering how to prevent this from happening 😅

[@CaffeMartellaSingapore]

It's not a common problem for the df54. But it seems to be a common problem for people who don't know how to use this grinder or coffee beginners.

[@sergeyermakov5971]

​@@CaffeMartellaSingapore I don't agree. The grinder as any other machine should be robust in doing its operations. I had a different grinder for 15+ years, it never choked. I had to give up on it, since the coffee machine itself died (it is a built in grinder). Just bought this one. In three occasions of grinding coffee it choked two times already. People say you have to be aware what coffee you are using, roast, oil content, how to pour the beans, etc. If it is so finicky I cannot call it a good grinder. After looking into it, I think its problem is not the quality of how it is made, but a bad engineering, poor design. I guess after its design the manufacturer didn't do good testing, otherwise it shouldn't have gone into production. One thing immediately goes into one's mind, the hole for the ground coffee spout is too small, it clogs very easily. It can be wider and chute can be redesigned too. I the family different people use the grinder, everybody used to the fact that operations should be simple. Pour coffee, press the button and get the result. So far I cannot say this grinder works this way, again, seems finicky not robust. Will give it a couple more chances before deciding if to return it.

[@chahahc]

I feel like just using blind shakers are superior to all the hassle integrated declumpers cause. Better declumping and no regrinding or clogging issues. Super Lube is a popular thread grease here in the states.

Hi thanks for sharing and it's greatly appreciated.

[@gwendafishley6368]

Hi CY, i would be scared to clean my grinder . Mine is the DF 64 first model .

Let me make a step by step guide!

hai boleh paham bahasa melayu? sir.. boleh introduce gemilai crm3149?

[@CaffeMartellaSingapore]

Hi I can't speak Behasa Melayu. Sorry my friends. But I think you are asking for Gemilai CRM 3149. Soon I will be doing some videos on this machine.

[@CurranLong]

But what if the grinder gets choked every 3-4 grind sessions? That is the case with mine. This much maintenance every 3-4 cups of coffee is not sustainable.

[@anelbarco]

My grinder just arrived today, haven't used it but I have the breville barista express with the grinder included. Maybe you're grinding too fine also try spraying your beans with water and give them a little shake? If it doesn't work maybe try different fresher roasted beans. If that does not work either maybe your machine is defective or it's not aligned?

[@CaffeMartellaSingapore]

Try to pour in the beans while the grinder motor is on. I have no issue with the grinder choking u less you are grinding too fine or pouring too much beans at one go.

[@KuddelDer]

ich bin sicher du hast die plastik membrane zerstört. keine gute idee da mit harten werkzeugen zu arbeiten.

[@waldip4474]

Im gonna be that guy, I’d be pissed if I paid for this “general service & cleaning”. I expected more than poking coffee out with a allen key and cleaning with a brush & vacuum cleaner.

[@CaffeMartellaSingapore]

Well. We spend time doing it and we will have to charge as we have rental and fees to pay.

[@waldip4474]

@@CaffeMartellaSingapore I understand the need to make a living and work shouldn't be free, but if I pay for a service like this I would expect more than what you showed in the video. as an example, I was really looking forward to you opening up the plasma generator, maybe testing it to see if it is working, doing a more in depth cleaning on that, perhaps taking the burrs apart to clean them exec.

[@CaffeMartellaSingapore]

@waldip4474 this is the gen 1 without the plasma ioniser. int t his situation, the choking is due to loading too much beans at one goal. And hence the job is the remove the clog and the choke coffee ground.

[@waldip4474]

@@CaffeMartellaSingapore are you not referring to the df64? I was not aware that there is a gen2 of the DF54

[@MegaFregel]

@@waldip4474if you don’t want to get charged you will have to clean it yourself. Like what the actual?
