Newbie with DF54 problem

I hope I am the problem, but I am suspecting my new DF54 is faulty.

I have been getting strange results to my coffee making so this morning I conducted an experiment with the follow steps and results:

1. Unscrewed dial and cleaned the machine out with a brush and some gentle air.
2. Put it back together ensuring that the pointer was aiming at zero.
3. Started the machine and carefully turned until I could hear the first signed of the burrs touching which was only a small amount beyond the zero. I therefore understand that my zero point is quite close.
4. Set to 15 and ground some beans for an espresso. Slightly low extraction but that could easily be my tamping.
5. Set to 55 to grind for V60 and boiled some water. Had a really bad extraction (1/2 of what I would expect) so went back to the grinder.

Now here is where I think there could be a fault. If I try and turn the dial back to a lower number, it is extremely hard to turn back below about 40.

6. Reset to 55 and turned it on.
7. Slowly tried to turn down the grind and by 40 the burrs are touching again!

So it is now completely out of whack. My zero point is now about 40….

Has anyone else experienced this? Am I going bananas?

Thanks

Did you take out the burrs during cleaning? This reeks of mis-alignment b/c of not puting the burrs back in in the same orientation, or having something stuck under the burrs.

That is the most positive situation. Based on this informatiion one could also conclude there is something wrong with the threads. Sorry.

Thanks for that.

I have not unscrewed the burrs, just taken the top disc off which includes 1 burr; not removed the bottom one. I wouldn’t have thought I should need to take them out on a brand new machine?

Strange thing is that if I take the disc off and clean everything I can get it back to zero being zero (or very close) but as soon as it’s used, it goes out of whack.

I have emailed the supplier for their thoughts.

An update:

After removing the disc/upper burr a few times and testing this, the zero point of course isn’t moving.

What looks like is happening is that after grinding at say 50, when I try and then go down to 15, the burrs sound like they are slightly touching and it is REALLY difficult to turn. Once I turn right down and then back up again, it “clears”. Looks like mis-aligned burrs.

Still waiting for the supplier to reply.....

I found a df54 locally for my brother, got to play with it for a while before I dropped it off to him. We found it did this on occasion, I wonder if it is chaff or larger particles when grinding coarse that are finding their way into the wavy spring and causing misalignment of the upper burr temporarily when you attempt to adjust to espresso levels. We found adjusting it back and further while running resolved it.

Did a full clean out, ensured no noise when moving all the way back to zero. Went a little past zero to hear the burrs start to touch.

Moved to 50 and ground a few grams. Turned off and removed cup.

Turned back on an is squealing. Turn down the grind slightly and noise gets worse. Press down on the grind ring and it stops.....

Looks like either the grind ring/wavy spring is not sitting correctly or the burrs are mis-aligned.

Make sense?

Thanks

Here is their answer:

"sometimes the burrs tend to sit unevenly on the motor which is a normal occurrence for the vertical grinders. Usually, turning the grinder finer until the sound occurs, then coarser, and repeating this till 0 should get rid of the sound. I have even recorded the burrs shimming to show the difference between the two."

I'm sorry but I don't agree with what they told you. I suggest you contact TurnGrinders.com. They're very responsive and should be give the best advice about their grinders.

That said, it wouldn't hurt to remove both the burrs and verify there isn't some debris that has gotten under the burrs but I still say contact Turin. On TurinGrinder.com there is a "contact us" and in my experience with them they are very responsive.

Just my 2 cents.

With the experiences you have had its amazing you mention the DF64...

I still believe these guys make good grinders, I owned a DF64V myself that worked very well but was just to loud - a general problem not limited to my unit.

Niche is proven and bullet proof. There are many passing on this forum that you might want to get.

If you want excellent customer service I would like to suggest the Option-O Lafom Casa.
