Meaning of E73
Look at the inlet control thermistor: E73 says its circuit is open. The entry is printed for the dryer lines behind sheet 137559700C (the 1302 edition) and sheet 137265000B (the 1202 edition).
Possible fault conditions: a defective inlet control thermistor, or defective wiring to it.
What happens next
Pull the plug at the wall and leave the diagnosis to a technician, who takes the resistance and wiring readings.
