Mahlkönig E65S Probleme

Problem might be really old/dry roasted coffee. Or a coffee that was kept outside and it dried out. Because you are grinding too fine and the coffee does static a lot, that means the coffee is old and dry.

What coffee is that and what is the roast date?

If you are having problems with coffee spraying all over use a tidaka ring.

Trichter


Later edit:

"(La Cafferia - Milano, Roen - Extra Bar) which are always fresh (Exp .: 12/20)."

Italian have a tradition to put the expiration date on the bag, that means the coffee was sealed in december 2018. The coffee was roasted before that, they let the gases to get out of the coffee for a period, then put it in bags. I would suggest to try with a different coffee.

 

Just for a comaprison I've made the pictures of grinding of 20.5g coffee similar date of roasting (Gardelli, Kenya Kiambu Handege, roasted 17.12.2018) to 17g basket (H = 24.x mm), how it looks with Tidaka funnel and without it. Grinder setting 1.0.

 

ich würde mich gerne im thread einreihen, ich bekomme meine neue e65s nämlich nicht zum laufen. der bohnenbehälter ist eingesetzt und festgeschraubt, aber die mühle lässt sich nicht einschalten, das display bleibt schwarz und die mühle gibt keinen mucks von sich. ich versuche jetzt schon über 1,5 stunden die mühle zum laufen zu kriegen, keine chance. ich bin mega genervt und mit meinem latein am ende. irgendjemand eine idee?

ist der auslöseknopf so ok? ich kann ihn nämlich reindrücken, aber er poppt dann sofort wieder raus. in der anleitung steht, dass man dann den support kontaktieren soll.

 

Du könntest noch versuchen, den Stecker in der Steckdose zu drehen. Aber auf jeden Fall ist ein Anruf beim Händler angezeigt, das Verhalten sollte keinesfalls vorkommen.

 

Be sure to twist the hopper all the way, which is possible, it's going really hard (due to silicone washer friction in the grinder throat). There is a safety switch under the hopper which prevents the grinder from operation without hopper in the place. The safety switch must be triggered (which is, if the hopper is tighten correctly).

 

yes I twisted the hopper clockwise until it made a strong click sound. I tried it several times but the grinder doesn’t switch on and the display is dead. I am already in contact with my dealer to see if they have any idea.

I am also not happy with the QA of Mahlkönig because my grinder has couple of black dots on the chrome grinder ring see the pic attached. its not dirt or anything because I am not able to remove it. reminds me to a polished surface rust.

 

Let us know, what has happened, what was the fault.

 

wie funktioniert denn der auslöseknopf? muss ich die mühle vom strom trennen und dann den knopf betätigen? ich werde da aus der bedienungsanleitung nicht ganz schlau. aber es kann doch nicht so schwierig sein eine mühle in betrieb zu nehmen? stell ich mich da echt zu blöd an?

 

ok, so the electronic doesnt seem to be damaged, as you can see in the video, if I press the tigger the grinder starts. But the hopper doesnt seem to trigger the pin to start the electronic. please let me know if I do something wrong but I am pretty sure I cannot twist the hopper more. and if I fix the screw also doesnt seem to solve the problem, I tried this several times, the head of the screw is already pretty damaged. I have the feeling the grinder seems to have kind of a deformation from the delivery. what do you guys think?

maybe someone can try if the grinder already starts if you just put the hopper but doesnt close the screw.

 

Which screw are you reffering to? Could you please also make the picture from the bottom of the hopper, if the plastic trigger arm isn't damaged?
Compared to my grinder, twisting of your hopper goes very easy, I have to use both hands to twist the hopper holding it by black base (I do not use clear upper hopper part, so can't hold it that way).

 

if I check the quick start video of the e65s:



my process looks exact the same, also the hopper twist kind of the same or am I wrong? does your e65s switch on if the hopper is empty? this is the only part where I see the difference. The hopper also looks fine to me, I cannot see damage or broken parts.

 

Yes of course, hopper can be empty and the grinder must switch on. From your video it looks to me, that the angle of hopper twist is lower, than in Vimeo, but maybe that's only illusion.
Anyway, the problem looks in triggering the shaft in the throat groove (first picture) with hopper plastic arm, so focus there. Eventually, if you have caliper, measure the distance from the groove top edge (2nd picture) until you hear the click of micro switch. On mine it's 9.4mm, while plastic trigger arm height is 11.8mm, so it's clear it must trigger the microswitch if properly twisted in place.
If you remove silicone washer from the throat and put the hopper in without washer (for easy twisting), you should also clearly hear the click sound of the micro switch when twisting the hopper.

 

if I remove the silicone, add the hopper and twist it and then push the hopper a bit to the left the grinder switch on. I can also see a gap between the hopper and the base see the photo attached when I twist the hopper with the silicone. do you see thr same in your grinder?

 

Yes, the gap is normal, by estimation 1.2 to 1.5mm, can't be measured by caliper. The silicone ring pushes the hopper upwards and also serves as a damping and ensures hopper in the position (hopper click sound). Check the necessary height from pin to trigger the switch with caliper like described above, so we can move forward, Either you do not twist the hopper enough (the last few degrees of twisting goes really really hard, at least on my grinder), or the micro switch is mounted too deep inside the body, so the triggering shaft is not pushed deep enough to trigger the micro switch. The measurement above tells us the answer.

 

ok, I think I found the issue, also thanks to you peter. If I place the hopper and twist it clockwise like in the video and try to switch on the grinder it is not responding but if I keep the hopper in the same position and then press the hopper on the top right and push it with high pressure towards the pin the grinder switch on. if I remove the preasure the grinder switch off again. So I think there is somehow something distorted and too much space between the pin and the hopper.

I talked to my dealer, I will return the grinder and he will send another one on the way soon.

 

You are welcome.
In such case it seems that the micro switch is not positioned well (usually there should be some space for vertical adjustment), but that would requires technician intervention, not suitable for unauthorized person. For temporary use you can underlay the hopper triggering arm with some thin plastic stripe.

 

@geri9, I'm curious, how it goes on with your problem.

 

geri9, kannst du etwas genauer leihen (Google Übersetzung hilft nicht)? Sagen Sie das, nachdem Sie mehr Kaffee gemahlen haben - was heißt Gratwürzung?

 

Hallo geri,

Dein Post ist ja schon länger her. Hast Du die Probleme gelöst? Ich habe seit 7 Jahren eine Mahlkönig Pro M, die auch seit geraumer Zeit fürchterlich streut (sieht ziemlich so aus wie auf Deinen Bildern). Reinigungsgranulat, Zerlegen & gründliche Reinigung, andere Bohnen, alles probiert....half nix. Die Lösung war schließlich, den Flapper genannten Gummilatz ganz oben im Auswurf mit Alufolie zu umwickeln, und zwar so, daß eine Lasche der Folie mit der Metall-Glocke verbunden ist, die das Mahlwerk abdeckt. Jetzt wird die elektrostatische Aufladung des Mahlguts über die Erdung der Mühle abgeleitet und die Arbeitsplatte bleibt sauber!

Wie ist Dein Langzeitfazit für die Mühle?
