Eversys Coffee Machine Error Code S-046: Keep Milk Tubes Attached

What does Eversys error code S-046 mean?

S-046 is a caution shown at the start of a cleaning on the Eversys Cameo. The screen reads "Don't remove the milk tubes from milk bladder!" and the e'Support table explains the reason: at the start of the cleaning, the milk in the tube or tubes is pushed back to the milk container. If the tubes are pulled off the milk bladder at that moment, the milk in them would end up on the counter or the floor instead of returning to the container. The table lists no causes because no part has failed; the machine is carrying out a step it does every time. It gives no length of time for the milk push-back, so we do not guess one. The action is simply to leave the tubes where they are and let the step finish, after which the routine moves on to the next prompt. The message is useful mostly to new staff, who may be tempted to disconnect the tubes early to speed up cleaning.

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 "Don't remove the milk tubes from milk bladder!"
• The cleaning has just started
• Milk is being drawn back through the tubes

Possible causes

Likely causes — what usually sits behind error code S-046 on this control. A technician confirms which one it is before any part is replaced.

• Cleaning has just started and the milk in the tubes is being pushed back to the milk container
• Staff already pulled a tube off the bladder, so milk is leaking and the step cannot finish
• A kinked milk tube slows the push-back, so the message seems to stay up for a long time
• The milk container was changed during the step and the machine is still waiting for the return

Safe checks before calling for service

How a technician diagnoses error code S-046

1. Confirm S-046 against the Cameo stop message table and the cleaning stage.
2. Inspect the milk tubes for kinks, loose joints or damage.
3. Check the milk container and bladder connection for leaks.
4. Check that the milk push-back actually completes by watching the tube and container.
5. Replace a tube or connector only if it is cracked, split or will not seal.
