First there is a way to open the locked door and get your clothes out. On this model of Kenmore front load washer you can manually release the door lock.
Unplug the washer from power.
Remove the front lower inspection panel (see the first image), and reach up to the bottom of the door lock and pull down on the small teardrop tab. This will unlock the door lock and allow you to get the clothes out.
The F70 error is a control failure that occurs when a signal from the main control to the interface (touch pad) is not detected.
This can be caused by a loose harness connection at the interface or main control. The image below will show how to remove the top so you can check for lose connections.
Be sure to unplug the washer first.
The F70 is an internal control problem. It can be caused by a failed central control board or an interface problem. The way to determine which part is bad when the error occurs is as follows:
If the error occurs when the machine is running then the problem is the interface.
If the error occurs when the washer is not running the problem is the central control unit.
The control and the interface are available from the following link:
