Eversys Coffee Machine Error Code S-041: Powder Unit Cleaning Step

What does Eversys error code S-041 mean?

S-041 is one step in the powder unit cleaning on the Eversys Cameo. The screen reads "Open powder unit and remove the mixer with pipe (A, B, C)," and the e'Support table describes it as a step in which the mixer, pipe and chutes are removed, washed and refitted. The actions it lists run in order: remove the chutes (D), clean all parts under tap water and dry them, put back the chutes, the pipe and the mixer (D, C, B, A), then close the powder unit. The table also gives a shorter wording for the same message: open the powder unit and remove the mixer, clean and dry the mixer, put the mixer back and close the unit. The letters refer to part markings that the machine's own screen and illustrations use, and the table gives no more detail than that. No causes are listed because the message is part of a guided routine. The control waits at this screen while the operator works, and it expects the unit to be closed again before it moves on.

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 "Open powder unit and remove the mixer with pipe (A, B, C)."
• The cleaning routine waits at this step
• The powder unit parts are dirty or sticky with product

Possible causes

Likely causes — what usually sits behind error code S-041 on this control. A technician confirms which one it is before any part is replaced.

• Powder unit cleaning has reached the step where mixer, pipe and chutes must be washed
• Powder has caked in the chutes, so the parts are slow to come apart and staff think the step is stuck
• A part was refitted in the wrong order and the unit will not close, so the screen stays on this step
• The parts were put back damp, so powder sticks again and the routine is repeated soon

Safe checks before calling for service

How a technician diagnoses error code S-041

1. Confirm S-041 against the Cameo stop message table and check which cleaning step the machine is in.
2. Check that all parts are present, undamaged and fitted in the right order.
3. Inspect the powder unit's closing and its detection for caked product or damage.
4. Run the step again and watch whether it moves on.
5. Replace a worn mixer or pipe only if it is cracked or will not seat.
