the display on my dgb-900bc is completely blank, no lights, but it's plugged in. is it dead?

Diagnosis

No power. This is usually a simple power supply issue, not a dead machine. Check the outlet and the cord connection first.

How to Fix It

Perform a power sequence.

1. Verify the outlet works by plugging in another device.
2. Ensure the power cord is firmly plugged into both the wall and the back of the coffee maker (it's removable).
3. Press and hold the 'Power' button for 5 seconds. Sometimes it needs a hard reset.
4. If still blank, unplug the machine. Wait 2 full minutes, then plug it back in and press 'Power'.

If That Didn't Work

The internal thermal fuse may have blown, often due to overheating from a clog or scale. This requires opening the base to check—a repair for experienced users or a technician.

Heads Up

Do not attempt to disassemble the machine while it is plugged in. If the internal fuse is blown, it's a safety response to a larger issue (like a failing heater).
