Malfunctions are upsetting. The error codes do help to get them fixed.
The E64 indicates a heater open circuit, heating element or wiring defect. Check heater coils and connections for open circuits. Replace heater and/or wiring, then retest.
Always disconnect the dryer when performing any service or repairs.
I would recommend just replacing the entire heating element to avoid overlooking a second defective part. Before taking that step, check the thermal fuse. It should read 0 on the meter. If it is the defective part, then you can save some money. The following video can help to access the dryer to make repairs.
The schematic image is below if you feel comfortable making these checks and repairs. If not, you can schedule a qualified technician here;
