Thank you for using Just Answer.
The heating element may not be your problem. Have you already checked the door switch, thermal fuses and motor relay? It is also important to actually check the voltage at the 220 volt outlet.
If you have not check these then, let me know and we can proceed. If you're confident about having checked that stuff we can take it from there.
Please send the model number.
Start with checking the voltage at the outlet. If you have a multi-meter set it for AC 110-120 volts. Then you would check each leg for voltage with the ground.
The ground is the "L" shaped hole. BE CAREFUL do not insert the probes into the other two holes at the same time.
Use ONLY one of the hot (straight blade holes) and the "L" shaped hole each time you test for voltage.
If you have any question about what I'm saying ASK. There is a lot of voltage at the outlet and you must be very careful where you put the probe.
Let me know how this goes.
