The "F70" fault code indicates a lack of communication between the machine control board and the console assembly. This type of failure code may require voltage tests using a volt ohm meter if you are not able to locate any loose wire connections. NOTE: I do not recommend checking voltages unless you have experience and feel safe and confident in doing so otherwise I recommend calling a service technician to diagnose and repair your dryer. I added instructions in the image below on how to access and what to test and the wiring diagram. I recommend calling a service technician to diagnose and repair your dryer if you are not able to diagnose the failure yourself using the information I added below.
The overheating has nothing to do with the error code. The overheating could be caused from not cleaning the lint filter, restricted vent system, heater relay sticking closed or a loose connection in the thermistor circuit. I will not be able to provide any part numbers without knowing the specific model number of your HE5 dryer. You can look up part numbers at Sears Parts Direct by entering your model number in the model number field.
F70 diagnostic steps:

SOURCE: F70 error code
The F70 and F71 error codes on this model of washer indicates a communication problem between the user interface control board and the central control unit (main control board). These error codes can sometimes be caused by a power surge or glitch through the electrical lines. Try unplugging the washer to completely disconnect electrical power. Wait 1 minute and then plug the washer back in to the see if the fault code clears. If it does, then the washer may work normally.
If the code reappears, then you could have a wire harness connection problem, a failed user interface control board or a failed central control unit. I recommend calling a service technician to properly diagnose and repair this type of problem so that the correct component can be replaced.
Be sure your unit is plugged into a 3 prong grounded outlet as well.
F71 is a "heatbeat failure" which means that your front interface control board is shorted and will need to be replaced. it's actually fairly easy to replace and can definitely be done by yourself. To access the part, just pull the unit forward and remove the 3 screws coming in from the back of the top panel. Remove the top panel by pulling it back, up, and off. Then remove all the screws going into the top of the control panel. Remove the dispenser drawer and remove the screws coming in through the dispenser. Remove the screws coming from the inside of the dryer going forward into the control panel, then remove the control panel (it's just clipped in on the bottom. After that you can disconnect the wire harnesses to the front interface control board and replace that part.

The "F70" error code is indicating a loss of communication between the Central Control Unit (CCU) and the user's interface board on the right hand side of the console. The main top can be taken off by removing the screws along the back edge of the top. NOTE: Disconnect the power cord from the power source before removing the top.
