What does Eversys error code S-003 mean?
The Cameo's control senses whether each bean hopper is in place. If the right hopper is not detected as seated, the machine shows "Bean hopper right missing." as S-003 and stops products that rely on that hopper. The maker's table gives a single action: check that the right bean hopper is inserted correctly. The most common reading is a hopper that was lifted out for refilling or cleaning and not pushed fully down. The table lists no cause other than the hopper not being in place. If the hopper is clearly seated and the message stays, the detection would need a technician's attention. Only the right hopper is named, so the left side is not described as affected by this message.

How a technician diagnoses error code S-003
- Check the hopper seat and the detection switch.
- Test the switch input on the board.
- Look for bent parts that hold the hopper up.
- Replace the switch after testing.
- Testing the hopper switch input means working inside the machine near live supply.
- A bent or worn seat is a repair, not a reset.
