What does Eversys error code W-094 mean?
The powder unit on a Cameo mixes powder with water in a small mixer driven by its own motor. When the control starts a powder drink and the mixer motor does not turn, the display shows "The powder mixer motor of the powder unit doesn't run." as W-094. The maker's table adds a single hint, to check if the motor is blocked, and names no other cause. A blockage here usually means powder that has caked in the mixing chamber, but the table does not say so. Without the mixer the drink cannot be blended, so powder products should be left off until it has been looked at. Do not force the mixer by hand while the machine is on.

Is the mixer broken?
Not necessarily. The maker's hint is that it may only be blocked.
Can I clear it myself?
Only by checking the mixer is fitted and clean with the machine off. If W-094 returns, call service.
What if W-098 also shows?
Then the mixer is not in place at all, and putting it back is the first step.
