Eversys Coffee Machine Error Code W-096: Left Cold Foam Milk Too Warm
W-096 means the milk for cold foam on the left side is warmer than 4 degrees C, which spoils the foam. Fill the left milk tank with milk at 4 degrees C or colder.
Low: a quality warning about milk temperature; the machine keeps running.

What does Eversys error code W-096 mean?
Cold foam depends on milk that is truly cold. The Cameo checks the temperature of the milk on the left side, and when it reads above 4 degrees C it shows "Milk temperature for cold foam is too high left." as W-096. The maker's table says that for good foam quality the milk must be at 4 degrees C or less, and to fill the milk tank with 4 degrees C cold milk. The table gives no other cause or action. Warm milk from a tank that was left out, or milk that was not chilled before it went in, is the plain reading of the text. The warning is about foam quality, so the machine does not stop, but the foam will not be right until the milk is cold enough.

Possible causes
Likely causes — what usually sits behind error code W-096 on this control. A technician confirms which one it is before any part is replaced.
- Left cold-foam milk is warmer than 4 degrees C
- A milk tank filled from a carton that was left out of the cooler
- A fridge or milk cooler that is not holding temperature
- A temperature sensor in the left milk path that reads high
Safe checks before calling for service
- Check the temperature of the milk before filling the left tank.
- Fill the tank with milk at 4 degrees C or colder, as the table says.
- Wait for the new milk to reach the sensor, then make the drink again.
- If it shows with cold milk, report the milk's temperature.
How a technician diagnoses error code W-096
- Measure the milk temperature with a thermometer.
- Compare it with the machine's reading.
- Test the temperature sensor and cooler operation.
- Replace the sensor if the readings disagree.
- Checking the sensor against the board needs meter measurements inside the machine.
- If an under-counter cooler is involved, it has a sealed refrigerant circuit that only a refrigeration technician should touch.
How error code W-096 differs from similar codes
The right side would have its own number; this message is for the left milk tank.
