SOURCE: error code F71

It seems the only solution any one has is to pull the plug. If this doesn't solve problem replace board. Seems to me if so many people have this same problem with fairly new washers its a design flaw and should be addressed by whirlpool. $600 for a new board seems outrageous for a new washer.

SOURCE: F11 Error Code

The F11 code often time comes with the FdL code, and the problem is in the CCU at the top of the machine. The connectors are weak but the true problem is the cold solder joints on the CCU. For access first unplug the machine then remove the three screws at the top, back of the machine. Slide the top back then up and the CCU will be in a plastic case at the top back of the machine. If you remove the circuit board the solder joints you want to touch-up are at the relays (5 of them) and the spade connectors at the edge of the board. The plastic enclosure is of poor quality also so if you break a few clips it's not your fault.

SOURCE: How do I know which

Hi

F71 is a communication error and is displayed when there is no communication from the User Interface to the Central Control Unit. First check the user interface harness for continuity and then check the wire harness to the user interface and CCU. If the drum rotates then replace the user interface, if the drum is not moving then replace the central control unit (CCU). Hope this helps...please post back for further assistance.

Whirlpool duet getting error code F70 and F71. When hitting start button, getting a clicking sound and nothing is happening. Cannot open the washer door as it is locked with clothing inside it.


Hi jreib29,

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.


Hope this helps.

Thank you for using FixYa.

Hello,

here is what the F71 error means and what must be done to check what is wrong

CENTRAL CONTROL HEARTBEAT FAILURE
If a cchb is displayed,no communaction is detected from user interface to central control unit

  1. check for continunity on the central control unit wire harness(check for continunity in all wiresfrom one end or plug to the other)
  2. check for good connection on all plugs from central control and interface
  3. replace user interface if drum rotates (by hand)
  4. replace central control unit if drum does not rotate

to summerize that, the main computer isn't talking to the touchpad/selector computer

Good luck, i hope this helps

Error code f70


Hi,

F70 Error code means 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.

F71 error code meansUser 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.

In both the above situations the following things are required to be checked and replaced where required:

1. Continuity of the User Interface harness.
2. 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.

Probably a control panel error


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.
