Mahlkonig E65s troubleshooting

[@SimonLeeds]

Thanks for the vid. The first one we got didn’t work within the first hr. Since they were fresh there was nothing to be found about the problems or service codes etc so had to send it back. It’s a great grinder and does make things so much easier.

Hi Simon, thanks for the comment and the info. Yes they are a game changer for sure. Have you seen the e-80 Supreme GBW it'll launch next year.. looks awesome. In a couple of years baristas wont need to know about gram throw. :)

I followed this video and it was exactly what I needed to make it work! My problem now is I’m 2 g off on a double basket, even though I have calibrated it and erased all the porta filter and reweighed them so I’m open to suggestions!

This just happened to me as I was setting up for a market last Saturday. Grinder just had a mind of its own. Main screen was often unresponsive. Grinder would grind by itself at random and grind a little bit every time I tapped the portafilter holder. Eventually it worked. But to test I brought it home and one time it randomly came on about 15 minutes after a dose and ground around 4 doses before I shut it off. Recalibrating seems to have fixed it, though my dose weights are still off. I also finally updated the firmware. Crossing my fingers that it will work because I have two markets this weekend. Without it I have to use my much slower Orion doser and Niche Zero.

Hey Todd, If you're in a market set up perhaps its not on an even surface? We wouldn't recommend GBW for outdoor settings and uneven workbenches. I'm glad you got going in the end though :)

@@silverskincoffee3767 I've been using it in markets for about a year without issues. I have weight tolerance set to low. It is actually more resistant to wind issues than the Acaia Orion bean doser and my Lunar scale. I suspect that packing and unpacking and just time somehow got the scale out of wack. My doses are getting closer now. I typically run the cart by myself so I need the speed of the GbW to keep up with the line. I suppose I could go to a time based dose if the weight issues remain.

@@silverskincoffee3767 4 months later and I just got another gremlin with the e65s GBW. The machine has worked flawlessly for 4 months at 2+ markets per month. This morning I set it up, turned it on, and it started grinding with 0g displayed. Nothing that I did would change the 0, as if the load cell was stuck. To get into any menu I had turn the grinder off then on and double tap the right wheel twice before it started grinding. I tried to calibrate with a 1kg weight (which I now carry with me), but that did nothing even though i said it was calibrated. I finally had to go into GBW failure mode and manually dose by holding the left upper button. Not sure why the grinder can't go back to a timed mode instead, but I didn't have time to work that out as the other vendors start wanting to buy coffee at least an hour before the market opens demanding a cup of coffee. I could not see any physical issues with the portafilter holder or load cell mechanism. Error log shows an overload every time I turn the machine on. Also, I finally remembered I could bypass the password by holding down both left buttons while turning the machine on. Much easier than entering a password. I believe that this is a feature added to a firmware update, so not all grinders may have it.

[@ToddJohnson15]

As a followup, I just spent 2 hours trying to fix my e65s GBW with no success. I did both resets, removed the load cell and portafilter holder to make sure it was all clean and installed correctly. Unless I am in GBW failure mode the grinder starts grinding when I turn it on, then shows the green screen of death. I have to turn the grinder on, then double click the knob before it starts grinding to go into the menu. Portafilter detection shows 1808.1 g on the load cell with no portafilter or weight on the holder. I can pull up on the holder to lessen the weight a few hundred grams, but that's it. Recalibration does nothing because it seems that 1808.1 g is the max, so adding a 1kg weight doesn't change the display. I think either the firmware has a glitch or the load cell is bad. 6 days before this glitch it worked fine for a 5 hour market. I always pack it back into its original box for storage and never pick it up by the forks or the plate below the load cell. What is most disappointing is the User Interface--the grinder should never lock the user out on that green screen.

[@ToddJohnson15]

The load cell stopped working again yesterday. Truning on the grinder just makes it start grinding. The load cell shows 1808.1g again. None of my fixes that worked before are working now. Mahlkonig really needs to work on this issue and they need to add a timed mode when in GbW failure mode.

I’m having the green screen of death issue on my e80s gbw. I’ve tried re-calibrating a few times and it will work for a minute but then go right back to being stuck on the green screen. Is it possible I have a bad load cell or need a firmware update?

[@AdiGoldsteinComposer]

Great video! Thank you for sharing! do you know how to update the E65S GbW software? I heard there is a new firmware version.

I have this grinder in my shop, and the lights that light up while grinding are not coming on. Is there a setting for this? Or possibly a problem?

[@silverskincoffee3767]

Hey Colby which model is it specifically? Is it an e65s or a e65s GBW?

@@gregoriusariharyadiwinardi2990 okay so you can remove hopper and strip it down until the sensor is exposed. You'll need to hoover it out and then hold the sensor down with an allen key and grind at the coarsest setting. I am presuming the blades are not spinning and are stuck with coffee. It's an easy fix!!
