Cleaning the Coffee Grinder
CAUTION – Unplug the grinder from the electrical power source.
Do not use cleansers, bleach liquids, powders or any other substance containing chlorine. These products
promote corrosion and will pit the stainless steel. USE OF THESE PRODUCTS WILL VOID THE WARRANTY.
1. Brush coffee grounds from the dispensing spout. Wipe off the surrounding area.
2. Make a mild cleaning solution. Mix dish washing liquid in warm water.
3. Avoid spilling liquid into the grind housing. Wipe exterior surfaces with a cloth moistened with cleaning solution.
5. Wipe exterior surfaces with a water soaked cloth to rinse off all traces of the cleaning solution.
6. Dry exterior surfaces with a clean soft cloth. Polish exterior surfaces with stainless steel polish.
8. Return power to the grinder.
A tablet style grinder cleaner may be used to clean the inside of the grind housing, the burrs and chute. The product
will eliminate taste and odor left in the grinder from grinding avored coffee. The regular use of grind cleaner reduces
the need to disassemble the grinder to clean it.
1. Empty coffee beans from the hopper. Plug power cord into the electrical outlet.
2. Place a container under the grind spout and run the grinder to empty the housing of all coffee.
3. Pour in grinder cleaner granules or tablets into the hopper (use manufacturer’s recommendations).
4. Press a grind button, running the grinder until the cleaner empties from the spout.
5. Rell the grinder with whole bean coffee and run two grind cycles to purge the grind housing of residual cleaner.
