The bean hopper lid on Gaggia Anima and Magenta machines uses a small round magnet to trigger a safety sensor that tells the machine the hopper door is closed. If the plastic cap that holds the magnet comes loose, the magnet can fall out, cause a “close your door” message, or in worse cases drop into the grinder and jam it (often showing an E01 grinder blocked error). This guide explains what the magnet does, how to identify a missing magnet, how to install a replacement magnet, how to reinstall the hopper lid, and a temporary workaround to use the machine while waiting for a replacement.
