What does Eversys error code S-033 mean?
The display on a Cameo is hinged so that it can be opened for access to the machine. A switch checks that it is closed, and when it reads open the control stops the machine and shows "Display open." as S-033. The maker's table gives two lines: please close the display properly, and check if the display is closed properly. It lists no failure cause. Most often the display has simply not latched all the way, or a cloth, cup or cable is keeping it from closing. The closure check is a protective measure, so the machine will not run while it reads open. If the display is clearly shut and the message stays, the problem is in how the closure is detected, which the table does not cover.

Possible causes
Likely causes — what usually sits behind error code S-033 on this control. A technician confirms which one it is before any part is replaced.
- Display not closed properly
- An object or cable caught in the display hinge so it will not latch
- A closure magnet or switch that has shifted out of line
- A display latch worn so the screen springs back open
Safe checks before calling for service
- Push the display firmly shut until it clicks.
- Look for anything caught in the hinge or edge.
- Wait a few seconds to see whether the message clears.
- If it stays with the display shut, tell the technician.
How a technician diagnoses error code S-033
- Check the latch, hinge and closure switch alignment.
- Read the closure switch input with a meter.
- Adjust the magnet or replace the switch.
- Close the display and run a drink to confirm.
- The closure switch is part of the machine's protective circuit and must never be bypassed.
- Checking the switch input means working near live wiring behind the display.
How error code S-033 differs from similar codes
Unlike the hopper messages S-003 and S-010 to S-012, this one is about the display housing and not about coffee supply.

Is it safe to hold the display shut and keep working?
No. The check is there to protect people, so fix the closure and do not prop it.
Why does it appear without anyone opening the display?
Vibration or a worn latch can let it spring open slightly.
It is closed but the message remains. What now?
The closure detection may be out of position, so report it.
