I would be afraid the coffee would get into the electronics and screw up the switches.
I've had to use coffee odor removal on all the new Wood REOs I've gotten and I have a few. DH and I are extremely sensitive to finish odors.
You can help to keep the coffee out of chip area by using some painters tape, but that won't close it up entirely. Leave bottle on and, if you want you can put some self stick kitchen plastic, or self cling, to put over catch cup. If you don't have a closeable container tall enough to accommodate the VVW, you can place the door in bottom of zip type baggie, then pour some course ground coffee in, a couple of inches, then put the VVW into the coffee, upright, so that it is sitting in an inch or so of coffee. Carefully close container and set in a place where it will remain standing and not get knocked over.
When you are finished "coffeeing" it you can use some canned air to gently blow out the electronic area.
You might find that you may have to do a coffee treatment several times. Some woods and/or finishes persist to hold the finish odor longer.
The same chip in VVW is in the Buzz Pro and is exposed to elements via the slit in tube for the wheel in the Buzz Pro. So I doubt that a little coffee dust will cause any problems.
