Eversys Coffee Machine Error Code W-044: CPU Machine Data Not Restored
W-044 means the machine data stored for the CPU could not be restored after a restart or update. The maker's table gives no operator action, so note what the machine is doing and call a technician.
Medium: stored settings may be missing, and the machine may not behave as it was set up.

What does Eversys error code W-044 mean?
The Cameo keeps its machine data, meaning the settings that describe how this particular machine is set up, in stored memory. When the control restarts or its software is updated, it reads that data back. If the read-back does not work, it shows "CPU Machine Data not restored" as W-044. The maker's table explains only that the stored CPU machine data could not be restored, and it gives no action and no list of causes. We cannot say from the table whether drinks still run on factory values or whether settings were lost, so check the settings you rely on, such as recipes and cleaning times, before trusting them. Restoring machine data is not an operator task and needs the maker's service tools.

Possible causes
Likely causes — what usually sits behind error code W-044 on this control. A technician confirms which one it is before any part is replaced.
- Stored CPU machine data could not be restored after a restart or update
- A software update that was interrupted partway through
- A power loss while the CPU was saving machine data
- A memory chip on the control board that no longer holds stored values
Safe checks before calling for service
- Write down the time of the last restart or update.
- Look at your usual recipes and cleaning settings to see whether they changed.
- Do not start a new update or reset on your own.
- Report W-044 with what you noticed in the settings.
How a technician diagnoses error code W-044
- Read the machine data and event history to see when the restore failed.
- Check the software version against the last one that ran cleanly.
- Reload the stored machine data from backup using the maker's tool, if one exists.
- Replace the CPU board only after the reload fails and the memory test points to it.
- Reloading machine data needs the maker's service software and the data set for this exact machine.
- Wrong data can change heating and safety settings, so it must be handled by trained service staff.
How error code W-044 differs from similar codes
Unlike W-043, which is only the display's memory, this one concerns the machine's own stored data.
