Tip & How-To about Whirlpool WFW8300SW

Whirlpool duet F70 and F71 error codes.

F70 and F71 are two logic board error codes that point at a communication error between the main logic module and the control pad (user interface and CCU), and between the motor control unit and central control (MCU, andd CCU that is main control module).
Repair is difficult, as motor, wiring and voltages from control modules must be tested.

Try first doing a reset, by disconnecting power cord or tripping circuit breaker and leaving power off for five minutes.

If that does not help and errors come back, then the best thing to do is calling the service number listed on the user manual.

Here extensive explanation of error codes and relative troubleshooting:

F70: CENTRAL CONTROL UNIT HEARTBEAT FAILURE
If a Central Control Unit Heartbeat Failure is displayed, no communication is detected from the Central Control Unit to the User Interface.

1. Check for continuity of the User Interface harness.
2. Check wire harness connections to the User Interface and the Central Control Unit.
3. Replace User Interface if drum is rotating.
4. Replace Central Control Unit if drum is not moving

F71: USER INTERFACE HEARTBEAT FAILURE
If a Central Control Unit Heartbeat Failure is displayed, no communication is detected from the User Interface to the Central Control Unit.

1. Check for continuity of the User Interface harness.
2. Check wire harness connections to the User Interface and the Central Control Unit.
3. Replace User Interface if drum is rotating.
4. Replace Central Control Unit if drum is not moving.

What do the following codes mean: F70 and F71. My washer is a Kenmore Elite HE5t. Thank you


Hello,

The F70&F71 mean basically the same thing

F70 means the main control board is not communicating with the cycle selector/touch pad control
F71 means the cycle selector/touch pad controlis not communicating with the main control board

What needs to be checked is the wires between the main control(CCU) and the selector(user interface) for good tight connections
If all connections are good and tight the CCU has to be replaced IF the drum will rotate under power from the motor

OR if the drum will NOT rotate under power of the motor the USER INTERFACE needs to be replaced
