What F4E3 means for a Maytag dishwasher: shorted heater relay or failed heater.

What this code means
F4E3
Heater relay shorted or heater failed.
Meaning
Two conditions fall under F4E3: the heater relay is shorted, or the heater itself failed.
Before anything else
Take the dishwasher off power. After that, the heater side is work for a technician rather than an owner task.
