Eversys Coffee Machine Error Code S-039: Fit the Red Grounds Drawer

What does Eversys error code S-039 mean?

S-039 appears on the Eversys Cameo when a cleaning is about to start. The screen reads "Please replace the grounds drawer with the red one," and the table in the e'Support article explains why: the red grounds drawer must be fitted before a cleaning can start. The red drawer is a separate part from the normal grounds drawer. As the table for the next message, S-040, explains, hot cleaning water is collected in that red drawer during the cleaning, which is why the normal drawer cannot stay in place. So the control checks that the right drawer is present before it lets the cleaning begin, and it holds the cleaning until that is true. The manual does not list causes for this message and does not describe how the machine recognizes the drawer. It only states the action: replace the drawer with the red one. This is therefore a preparation step in the cleaning routine, not a sign that something has failed. Once the red drawer is in, the cleaning can be started. After the cleaning, the normal drawer goes back in.

Affected models and control systems

Eversys Cameo range (Cameo/Core, Classic, ST and in-box versions). The message is listed in Eversys' e'Support table of operator stop messages for Cameo, and the table gives no board revision or model limit.

Code numbers and their meaning can change between control generations. We match the full model and control before acting on a code.

What you may notice

• The screen shows "Please replace the grounds drawer with the red one."
• The cleaning will not start
• The normal grounds drawer is still in the machine

Possible causes

Likely causes — what usually sits behind error code S-039 on this control. A technician confirms which one it is before any part is replaced.

• A cleaning has been started and the normal grounds drawer is still fitted instead of the red one
• The red drawer is stored elsewhere or was lost, so staff keep trying to start the cleaning without it
• The red drawer is fitted but not fully seated, so the machine does not register it
• Staff on a different shift do not know the red drawer step and skip it

Safe checks before calling for service

How a technician diagnoses error code S-039

1. Read the message and confirm S-039 against the Cameo stop message table.
2. Confirm a genuine red drawer is fitted and seated, and that it is the right part for this model.
3. Inspect the drawer's seat area for damage or obstruction.
4. Run the cleaning start and check the message clears.
5. If it persists with the correct drawer fitted, test the drawer detection before replacing anything.

How error code S-039 differs from similar codes

S-039 is the setup step before S-040. S-039 asks for the red drawer to go in; S-040 asks for it to come out again, carefully, after the hot cleaning water has filled it.
