Your machine is draining too slowly. When it initiates a drain cycle, the water level switch is sensing the water level is still too high after 60 seconds so the computer stops and generates this fault code.

Here are the things to check;

* Check the drain hose and make sure it is not plugged or inked.
* Check Wire Harness connectors to the Drain Pump, Pressure Switch, and Central Control Unit (CCU)
* Check/Clean Drain Pump Filter of foreign objects
* Check for Drain Pump Failure
* Check the Inlet Valve for proper shut off
* Check the Pressure switch for proper operation

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.

F70 code on washer nothing will work


Hello & Welcome to FixYa

F70 is a communication error which is caused when no communication is detected from the user interface to the CCU (central control unit). Please check the wiring to user interface and the central control unit, if that is fine and you can see the drum rotating then replacing the user interface is recommended repair. If the drum won't turn then the CCU needs replacement. Please get back to me if you have any other questions.

How do I know which user interface I need for an error code F71? I'm getting an F71 error code. The washer will not start at all. Model WFW9200SQ00 Whirlpool


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.
