How can I remove odor and coffee oils from the grinder?
Simply grind rolled oats or instant oats, wipe with a damp (not wet) towel, and dry immediately. Excessive moisture will damage the grinder.
Is my grinder applicable to an electric screwdriver/drill?
The 6.35mm electronic screwdriver/drill is applicable to all the 1Zpresso grinders and it doesn’t need to be a powerful one.
We suggest using a drill for one or two cups within a short period of time, or it could get hot and affect the taste.
Grinds are sticking to the inner side of the catch cup and the internal adjustment dial. How do I fix this?
Spray some water on the beans to eliminate static.
Notes: Excessive moisture will damage the grinder, so be sure to store the grinder at a dry location.
How long is the lifetime of my grinder? Can I replace the burr?
The burr in the grinders were calibrated by our team to ensure maximum stability over time, and it is expected to grind up to 100~200 kg beans. We’re developing a burr replacement service, so stay tuned.
Is the small scratch on the surface of the catch cup normal?
Minor imperfections on the surface of the metal are to be expected during the aluminum anodizing process. Our QC team is limited to substantial cosmetic defects.
Are variations in the grain of the wood of the handle knob considered normal?
As a natural product, wooden ball exhibits variations in grain and smoothness that synthetics don’t. These variations are considered normal and desirable.
Do you offer a warranty or guarantee on your product?
All 1Zpresso grinders are under an one-year limited warranty for defects in materials and workmanship.
