OK, it seems the thermostat might have tripped, please check this IMAGE.
You will have to unplug it and pull it out, then remove the top off the appliance.
Then check part#3, if it has a RED reset button press it, if that one has a small hole take a pin and press to reset it.
After that is done, reconnect everything and plug it back.
Now check if everything works fine.
If the problem is still there, you will have to test part#3 and part#48 for continuity.
Replace the part that is faulty.
However, looking at the age of appliance reset should help.
Let me know how it goes.
