It doesn't start the sensing estimated time after a few minutes F70 pops up
Hi,
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.

Apparently this problem "Suds" and "F35" error codes is happening to a lot of people ~ If you do not have any clogged hoses, then the Analog Pressure Switch is more than likely the issue.
Here's the downside, the problem is so wide spread that the part is back ordered for weeks. You would think that SEARS Extended Warranty Service would keep this part in stock so their customers are not without a brand new washer for over a month!

I had a suds error and then a F 35 error. Turns out I had a collection of junk and debris between the door seal and the drain at bottom of door. Cleared out the debris now my washer is running like a top. (washer senses pressure error, thats why I got said error codes)

I actually had the same problem and read some other blogs and found that this is a control board issue. Whirlpool actually had a recall on these boards and should cover the part and labor to fix. I called them today at 1-800-253-1301 and they are coming out to fix my washer this week. When you call they just need the model number and the serial number. Both can be found just inside the lid on your washer. Good luck!
SOURCE: 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.
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.
