Eversys Coffee Machine Error Code W-093: Powder Pump Not Running
W-093 means the powder pump of the powder unit did not run. The maker's table gives no operator action, so stop powder drinks and have a technician check it.
Medium: powder drinks cannot be made correctly until the pump runs.

What does Eversys error code W-093 mean?
A Cameo powder unit uses a pump to move powder or air to the point where the drink is mixed. When the control calls for it and it does not run, the display shows "The powder pump of the powder unit doesn't run." as W-093. The table states only this meaning, with no remedy. The related messages for the dispensers and the mixer motor add "check if it is blocked," but W-093 does not, so we do not assume a blockage here. Without the pump, powder drinks cannot be made correctly, so leave them off the menu until it has been tested. Regular coffee is not described as affected. No blockage hint is given for the pump, so a person at the machine has little to do except stop powder products and report the message.

Possible causes
Likely causes — what usually sits behind error code W-093 on this control. A technician confirms which one it is before any part is replaced.
- A pump that has stalled or lost its supply
- A pump hose that is blocked or kinked
- A loose connector at the pump
Safe checks before calling for service
- Stop ordering powder drinks.
- Make sure the powder unit is closed and seated.
- Do not open the powder unit while it is powered.
- Tell the technician if W-094 or W-091 also appeared.
How a technician diagnoses error code W-093
- Run a powder product and listen for the pump.
- Check the pump supply and connector with a meter.
- Inspect the pump hose and outlet for blockage.
- Replace the pump after testing shows it is the failed part.
- Pump supply is live inside the machine.
- A pump that runs but moves nothing needs the hose path traced, which means opening the unit.
How error code W-093 differs from similar codes
W-091, W-092 and W-094 name the dispensers and mixer motor and tell you to check for blockage; W-093 does not.
