Eversys Coffee Machine Error Code S-102: Emptying Steam Boiler

What does Eversys error code S-102 mean?

S-102 is a progress message on the Eversys Cameo. The screen reads "Empty steam boiler..." and the e'Support table says it is displayed during the process of emptying the steam boiler. The listed action is to wait until the boiler is emptied, or to abort by pressing the stop button in the upper left corner. So the control is carrying out a deliberate routine and tells the operator it is under way. The table gives no causes, because nothing has failed; it does not say why the boiler is being emptied, how long it takes or what the machine does next. From the neighboring messages we know that S-101 (switch off the machine) can appear after the boiler has been emptied. The stop button gives the operator a way out, but the table does not describe what state the boiler is left in after an abort, so we do not claim one. Our advice is to let it finish unless there is a reason to stop.

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 "Empty steam boiler..."
• Water or steam is not available while it runs
• Sounds of draining from inside the machine

Possible causes

Likely causes — what usually sits behind error code S-102 on this control. A technician confirms which one it is before any part is replaced.

• Steam boiler emptying routine is running
• Someone started the routine from the menu for transport or maintenance and others did not know
• A routine ran after a cleaning, so it looks unexpected
• A slow drain makes the message stay up longer than staff expect

Safe checks before calling for service

How a technician diagnoses error code S-102

1. Confirm S-102 against the Cameo table and ask who started the routine and why.
2. Watch whether the emptying completes and whether S-101 follows.
3. If it stalls, check the drain path for blockage.
4. Check boiler level behavior after the routine.
5. Test drain valves and level parts if the boiler does not empty.

How error code S-102 differs from similar codes

S-102 is the emptying stage. S-103 is the depressurizing stage of the same family, and S-104 is the opposite case, where the boiler is being filled.
