Eversys Coffee Machine Error Code W-010: Invalid Coffee or Milk Recipe

What does Eversys error code W-010 mean?

The Cameo control builds each drink from a stored recipe, which sets things like quantity and milk use. When a drink is requested with a recipe the control cannot accept, it shows "Invalid coffee or milk recipe." under code W-010 and does not make the drink. The maker's table is clear that this is self-clearing: the message disappears with the next successful coffee product, and no operator action is required. It does not list any cause. The warning therefore tells you the request was rejected, not that the machine is damaged. If the same key keeps producing it, the recipe attached to that key is the thing to look at, and that is a settings matter rather than a repair. Other keys that make drinks normally show the rest of the machine is working.

Possible causes

Likely causes — what usually sits behind error code W-010 on this control. A technician confirms which one it is before any part is replaced.

• A product key whose recipe was edited and left with an out-of-range value
• A recipe that asks for milk when milk is not set up on that side
• A recipe that was not fully transferred after a settings update

Safe checks before calling for service

How a technician diagnoses error code W-010

1. Note which product key raises W-010 and whether other keys work.
2. Open the recipe for that key in the service settings and check each value against the factory values.
3. Verify the milk options match what is installed on the machine.
4. Restore the recipe and run the product to confirm the warning stays away.

How error code W-010 differs from similar codes

Unlike the warnings about parts that have stopped working, this one concerns only the recipe and clears by itself.
