DIAGNOSIS: Power isn't getting to the control board. On this model, there's a known quirk with the power cord connection inside the unit.
FIX: Unplug it from the wall. Tilt the machine back and look at the bottom. You'll see a small, rectangular access panel held by a couple of Phillips-head screws. Remove that panel. Inside, you'll see where the power cord connects to the main unit—it's a simple plug. Make sure that connection is fully seated and secure. Reattach the panel, plug it into the wall, and try again.
IF THAT DIDN'T WORK: The internal fuse on the control board might be blown. This requires opening the main cabinet and is a more involved repair, likely needing a service technician.
HEADS UP: This often happens during shipping or rough handling. That internal cord connection can come loose pretty easily. It's the first thing to check before assuming the unit is dead.
