I have a ESTRO commerical counter top model with grinder and dry powder mix

Question edited for clarity.
Question moved to Miele.

This particular machine ends up on Fixya a couple of times every week!

Some Miele machines have a lever to adjust the grind coarseness. Page 27 of the manual below. I would also give it a good clean beforehand to check there is nothing in there that shouldn't be.

You will need to pull the grinder apart & clean it out. Most likely cause of the grinder blocking up is a leak somewhere inside the machine dampening the grounds as they exit the grinder. They bind up, won't fall out and there is your blockage. You will need to find and fix the leak, there are many, many places for the leak to be, it's a job for a Krups Service Agent. I have outer housings with cutouts in them so I can run them and look inside at the same time to find those troublesome leaks.

This is a COFFEE GRINDER. Designed to grind coffee beans to into a powder . This powder is then put in a coffee machine or a coffee peculator to brew coffee. DO NOT put water into the coffee grinder !

One posible problem is the coffee shute. This is leading aslo to the passage where you put the grinded coffee and cleaning tablets. This might have be clocked from dry coffee mixed with humitity or steam. So you can use a bending brush similar to the one used to clean babes milk bottles and at the same time vacum with air vacum cleaner.
You can make perfect cleaning if you remove the top platic panel and visual check that everything are perfectly cleaned.
The last thing that is possible for the problem is weak ginder motor which have lost its power so it can grinds but not have the power to push the grinded coffee all the way through chute to the coffee group. In this case you will need new grinder motor.
Hope that this can help you, good luck.

I have a copy which I'm getting ready to sell with the Grinder.

You need to open the grinder, it`s probably packed with old fine powdered coffee that blocks the outlet. Clean this out and try again. Since it works normal when you use pre-ground coffee, there shouldn`t be any problems with any other parts.

Let me know if you want a description for have to open and clean the grinder.

Good luck!

I have a Zass and sometimes have a problem with it self adjusting, but when I do need to adjust it, I find that I have give it a good tap on the top to make sure it adjusts. So, just turn the knob counter clockwise as far as it will go, then give it a good knock on the top and bottom and try again. My mill offers the full grinding range, from a fine powder to large chunks.

You will need a manual that has all the instructions for your machine, as this is too long a subject to answer here. The manual for your machine can be found at: http://www.bunn.com/pages/techdocs/manuals/grind.html

Do you need the user's manual or circuit diagrams?
