Hi, F70 means that the dishwasher senses the motor running even though control board is not telling it too. Here would be the reasons for this 1) There is water in the base pan so it has flooded and is trying to remove any water remaining in the tub. 2) Your control board relay is stuck.
If you want to to check for water in the base, you need to uninstall the unit tip it on it's side and remove the 4 screws on the bottom of the base pan. If you remove the pan and see water you need to determine where it's leaking from. If not you need a new control board.

What does F70 mean on a front load dryer?


Hello Carol;

My name is Peter. I am a retired field service appliance technician.

F70:

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, have a technician diagnose the cause of the communication failure. The main electronic control board and/or the user interface control assemblies might need to be replaced.

What does F70 flashing mean?


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.

What does code F70 and F71 mean on my whirlpool duet?


Error code F70 means no communication is detected from the Central Control Unit (CCU) to the User Interface while F71 is the reverse; no communication detected from the User Interface to the Central Control Unit (CCU). This could simply mean a loose or poor connection between the two communicating boards.

Disconnect power to the washer prior to servicing to avoid the risk of electric shock.

Remove the three screws attaching the top panel to the rear of the washer then slide the panel rearward and lift it off the washer.

Disconnect the User Interface ribbon connector from the left side of the Central Control Unit (CCU) and clean the connector and terminals thoroughly. Reseat the connector several times to ensure a good connection between the Central Control Unit (CCU) and the User Interface.

It is highly recommended to clean and reseat every wiring harness connector from the Central Control Unit (CCU) to prevent the same problem in the near future.

Reconnect every wiring harness to the CCU and make sure all connectors are firmly seated. Slide the top panel back into position and secure it to the rear of the washer with the screws previously removed.

Let us know if the problem persists for further assistance. We will be happy to resolve your problem.

F70 error code


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.
