F:31 Low L2 voltage The L2 leg of 240 volt power is below 30 volts. Check the house circuit breakers for the dryer and reset the L2 breaker if it's tripped. Unplug the dryer and check the power cord wire connections on the terminal block. Reconnect any loose wires or replace the power cord if it's damaged. Have an electrician check the 240 volt power supply for the dryer.

F:70 or F:71 No communication between the electronic control board and the user interface control board assemblies Unplug the dryer. Check the wire harness connections between the main electronic control board and the user interface control board assemblies. If the connections are sound, contact a technician to diagnose the cause of the communication failure. The main electronic control board and/or the user interface control assemblies may might need to be replaced.
