What does Eversys error code S-011 mean?
The Cameo's brewing module checks for ground coffee in the chamber. If the left hopper gave none, the control stops and shows "Bean hopper left is empty or locked." as S-011. The maker's table says the brewing module has detected no coffee powder in the chamber and that the left bean hopper has to be refilled or unlocked. As on the right side, the two readings are an empty hopper or a locked one. Compared with W-084, which warns the level is low, this message appears after a drink has actually failed. Refill or unlock the hopper, and the next drink should brew. Only the left side is named, so right-side products are not described as affected. The table words it the same way as the right-hand message, apart from the side.
