A model number may help others help you.

Most units have a thermal fuse often mounted on the blower assembly that will kill power to the unit.

If yours has this perhaps it is blown.

The most common cause of it blowing is a dirty vent system.

I have to do some guessing here.
I cannot find any info on a DLW but following is a manual for a DLE

With luck yours will be the same or very close.

Looks like the parts on the blower will be a thermistor not a thermal fuse.

Looking at the wiring diagram there is not a fuse that would kill power to the board and light so how did you check for power?
There should be 120 volts between L1 and Neutral.
Did you just visually checked the breakers I would turn them off/on a couple times. Sometimes you can loose half the line without tripping the breaker.

Check the voltage at the plug
L1 to L2 should be 240 volts
L1 to Neutral and L2 to Neutral, both should be 120 volts.
If OK
Unplug the unit and check the wires at the terminal strip in the machine to make sure none are loose or burned out
If OK
Check the power at the terminal strip.
Do this with the heater off and on.

Have you looked in the unit to see if you can find the tech sheet.

If the unit is wired as the one I found then there must be a wire off or something like that since the drum light is just one side of the door switch and it looks like the control board is never shut off.

I would check the door switch.
