What does Eversys error code W-043 mean?
The Cameo touch display runs its own software, and its memory use grows as menus are opened and closed. When it passes a set level, the control shows "Memory usage too high." as W-043 and recommends restarting the display. The maker explains that going into the menu makes the display's memory use higher than before, and that past a certain level it is recommended to press Continue to restart the display. This restarts the screen, not the brewing parts, and the table lists no other cause. The warning is a housekeeping prompt. It does not point to a failed part, and a restart normally brings the memory back down, though the table does not say how often it can recur.
