coffee grinds in threaded part of overall body
When removing the top burr carrier of a high espresso grinder, it is extremely important to clear the threads of the top burr carrier as well as the threads inside the grinding chamber.
|Top burr carrier of Quamar M80E with ground coffee particles|
a) One single particle of coffee grind can prematurely stop the top burr carrier from touching the bottom burr. This is important because the touching of the two burrs is the actual zero point of the coffee grinder, and
b) a single particle of coffee grind can actually damage the threads on the top burr carrier as well as the threads in the grinder chamber. Although the top burr carrier is cheaper to replace, it is very expensive to replace the threads in the grinding chamber as the entire body needs to be replaced.
To remove the grinds from the threads, please use cotton swabs dipped lightly in olive oil. Wipe clean all olive oil residue before re-inserting the top burr carrier. If you come across any resistance while re-threading, stop, remove top burr carrier and re-clean coffee particles from threads. Inspect for any thread damage and repeat.
