Delonghi esam 4200 wate ground bin light flashing

Recommended Posts



Our delonghi 4200 machine stopped working recently and the only light flashes is the beans waste ground bin, i cleaned it and also checked the micro switch behind the bin and it clicks all okay. 

I have uploaded a video on youtube of the issue https://youtu.be/-IywKzkj8jE

if anyone has any suggestions that i can do to check before i pay someone to fix it, it would be really helpful.

Hi Gokhan

You only need to empty the grind bin when the light stays on (ie. not flashing) 

When the grind bin light flashes, it means there is no coffee in the brew unit.  This can be due to the following:

- Your machine is out of beans (although i'm guessing you would of already noticed if this is the case)

- You have the machine in "pre-ground coffee" mode and have not added any pre-ground coffee in the chute.  You will encounter this problem if you have your coffee size dial turned too far anti-clock wise.

- You have your grind size set too fine, and as a result no coffee is making it through your grinder(this is very common if you are using supermarket coffee beans)

If you no longer have the manual (or struggle to read the extremely small print like I do), you can get a pdf of it here:


Out of interest, what beans are you using? and how old is the machine?
