See the attachment for the tech sheet.
Check that the unit is getting 240 volts.
The motor and control board use 120 volts but the heating element requires the full 240 volts.
Try flipping the breaker off/on slowly a couple times. Sometimes you can loose half the line without actually 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.

If power is OK run the diagnostics.
Unplug the unit.
Place one meter lead on the blue wire at the control board that goes to the heater. Leave that lead there and then chec kback through the heater circuit.
Use your most sensitive resistance scale of the meter.
So one side of the heater will be 0 ohms, the other side will be about 10 ohms.
Both sides of the hi-limit thermostat and the Safety thermostat should also be 10 ohms.
One side of the centrifugal switch on the motor should also be about 10 ohms.
That is the heater circuit checked out so all that is left in the circuit is the centrifugal switch and the heater relay.
Unplug one side of the thermistor and check its resistance, should be around 10,000 ohms.
