466DC LINK over/low voltage error

Name in the manufacturer's documentation (service manual): DC LINK over/low voltage error[1]

In plain words (editorial)

The DC link voltage is too high or too low; the unit restarts in 3 minutes. The service manual checks the input power and the AC power connection.

When to call a service technician: If it repeats, contact an authorised Samsung service technician or your installer.
