Are you absolutely sure you have power to the dryer? Check your circuit breaker to the dryer and see if it tripped first.
I always check the voltage at the terminal block where your dryer power cord hooks up to first. Use a
multimeter to check for 240 volts across the 2 outer terminals.
So pull the dryer out from the wall, then unplug it, then open the access panel where the power cord wires mount on the dryer terminal block, then see if you notice any burnt wires.
I see this happen a lot too:
If no burnt wires, then plug the dryer back in and put your meter leads on the two outer terminals and see If your getting 240 volts across the outer two terminals.
I'm attaching your data sheet below, Look on Page 4 and 5.
Unsuccessful Activation If entry into diagnostic mode is unsuccessful, refer to the following indications and actions:
Indication 1: None of the indicators or display turn on. Action: Select any cycle.
--->If indicators come on, try to change the function for the three buttons used to activate the diagnostic test mode. If any button is unable to change the function, something is faulty with the button, and it will not be possible to enter the diagnostic mode using that button. Replace the user interface and housing assembly. Refer to Dryer Disassembly Instructions, page 24.
--->If no indicators come on after selecting the cycle, go to TEST #1, CCU Power Check, page 11.
Indication 2: Console indicators begin flashing immediately. Action: If console indicators begin flashing on and off immediately, replace the user interface.
