Occasionally a user reports statically charged coffee grounds coming out that seems to defy the laws of gravity. They float up into the air and cling to things, making a mess!

Often it will stop on its own after the impeller gets a few days of use. It's a bit of a mystery however, I believe the issue arises mainly in dry climates, with certain beans in combination with the plastic impeller.

To fix the issue, simply give your impeller a scrub and rinse in the sink and then pat it down with a towel until dry.

This slight bit of moisture seems to take care of static issues permanently. I suspect it gets us by until the impeller builds up a natural coat of coffee, which also serves to prevent static charge.
