The control panel is completely dark; the unit does not respond, but the outlet has power.

Safety first: Turn off power at the breaker and unplug the unit before opening any panels. Only qualified persons should work on mains circuits.

• 1. Verify outlet:
  • Test the outlet with another device to confirm power.
• 2. Inspect power cord:
  • Check for cuts, burns, or kinks; replace if damaged.
• 3. Access mains entry:
  • Remove the rear and lower panels to inspect the mains terminal block and line filter.
  • Ensure connections are tight and there is no visible damage.
• 4. Internal fuse:
  • Some Miele boards have a replaceable fuse; if blown, investigate the cause before replacing with the exact type and rating.
• 5. Main board replacement: If power reaches the board but it remains dead, the board’s power supply is likely failed and the board must be replaced by a technician.
