Eversys Coffee Machine Error Code W-024: Milk Tank Empty
W-024 means the right-side milk tank is empty and a milk product was aborted. Refill the milk tank, as the maker says.
Low: a refill message; the machine runs normally once the tank is filled.

What does Eversys error code W-024 mean?
The Cameo watches the milk supply on each side. If a milk product is running on the right and the tank runs dry, the control aborts that drink and shows "Milk tank empty." as W-024. The maker's table gives a direct instruction: refill the milk tank. The aborted drink is lost, so make it again after the refill. The table names the right side only, so a similar message for the left tank would carry its own number. The warning describes a supply condition rather than a machine problem. If the tank is clearly full and the message still shows, the level detection would need a technician to look at it, but the table does not describe that case. Because the aborted drink is not completed, the cup may hold coffee only or nothing at all, so check it before serving.

Possible causes
Likely causes — what usually sits behind error code W-024 on this control. A technician confirms which one it is before any part is replaced.
- Right-side milk tank empty while a milk product was running
- A milk tank filled only part way before a rush
- A level sensor in the right tank that reads empty when milk is present
- A milk tube that slipped out of the milk in the tank
Safe checks before calling for service
- Check the right milk tank and refill it with cold milk.
- Make sure the milk tube sits in the milk and is not kinked.
- Make the aborted drink again.
- If it shows with a full tank, note the fill level and report it.
How a technician diagnoses error code W-024
- Confirm the tank is full and the tube reaches the bottom.
- Check the milk level detection for the right tank.
- Run a milk product and watch for steady flow.
- Clean or replace the level sensor only if its reading disagrees with the tank.
- Level detection is wired into the machine's control board and needs testing with the machine powered.
- A false empty reading can be a sensor or board matter, which operators should not open up.
How error code W-024 differs from similar codes

Do I lose the drink?
Yes. The maker says the milk product was aborted, so it needs to be made again.
Can I serve coffee?
The message concerns milk only. Coffee-only drinks are not described as affected.
It says empty but the tank is full. Why?
The table does not cover that case. Report it, because the level reading may be wrong.
