what the F-7, E-5 error codes mean ?

The F7-E5 error code is a shifter fault error code. The most common problem related to this error code is going to be that the actuator (shifter)has failed. Check broken or loose wires or connections at the control board and actuator. Also, check that the pulley nut has not came loose causing the pulley to drop and rub into the motor shield under the unit. This may cause this error code as well. This would of caused the washer make nose as well. If every thing is good I would replace the actuator. A bad control board can also cause this error code, but the actuator is most common. I have attached a link to the part and to a repair video. I hope this is helpful.
