We show you how to clean the Malhkonig EK43 grinder.

-

The EK43 stands out for its performance, precision and versatility, making it an indispensable tool for specialty coffee professionals who seek the best in every cup. To maintain its performance, it is key to clean it regularly and avoid accumulations that affect the flavor.

Here we show you how to maintain it correctly:

Step 1: Disconnect the Mill.

Step 2: Adjust the grinder to the largest grind number. Remove the two side screws holding the grinding wheel container. Remember, DO NOT FORCE the parts. Gradually alternate pressure between the two screws to remove them.

Step 3: Once you have removed the container, remove the support plate and carefully remove the outer grinding wheel.

Step 4: Proceed to remove the spacer bushing on the inside.

Step 5: Deep clean the internal grinding wheel without removing it from the grinder, making sure to remove any remaining ground coffee. Then, clean the other grinding wheel and the rest of the parts.

Step 6: Before reassembling, remember that the spacer bushing and backing plate should be greased with food grade grease and the shaft should be aligned (always be careful not to get grease on the grinding wheels or any other parts).

Step 7: Once the parts are clean and greased, reassemble the bushing and spring together with the outer part. Use the backing plate to hold them properly, then put the front part on and tighten the two outer screws gradually and alternating the screws to get a symmetrical fit of the part.

Step 8: Now, let's adjust the mill to zero point. Position yourself at the coarsest grind and loosen the allen screws on the selector or thread and move the needle to the finest grind number, then use a flat screwdriver to bring the grinding wheels closer together until they barely rub together. It is important to pay attention to the sound it makes.

Step 9: We turn off the mill and tighten again the allen screws of the selector or thread in the finer grind.

Step 10: Turn on the mill and check that everything is working properly.
