I have the same problem. I contacted Whirlpool,they said to call an electrician. Electrician said it was a MOTOR CONTROL BOARD. My price to fix in Fl. was $430.00, $400 for part and 30 labor. I had a coupon other wise it would have been right at $500. Hope this helps!

On Whirlpool duet steam front loading DRYER...What does the error code F70 mean?Do you have to have a certified whirlpool appliance service professional to repair?

F70 code says...
Replace the machine control electronics. You should first unplug the machine and then remove and plug back in all connectors on the front panel model as well as the electronic control module.

If that doesn't take care of the problem then it may be time to consider replacing the rear board. The FSP # 8183259

The control board is part # 14 in the link below.

I bought in June 2010 a Whirlpool Duet washer Model WFW9400SU00 Serial CSU2113432. Could not install it till April of this year and finally started using it in June for 6-7 washings, then the error F70...

F70 is "Central control unit heart beat failure" No communication is detected from the Central Control Unit to the User Interface. (In english, this means that the controler unit mounted in the bottom of the machine, probably in a plastic cover, has stopped talking to the control panel on the front of the machine where you push the buttons).

You need to take the top off the machine and check that the wiring harness between the 2 units is intact and that the plugs on the ends of the harness are firmly in place on both the Central Control Unit and the User Interface. If this fails to fix the problem, then the action indicated is that if the drum is rotating while this error is showing, the user interface is faulty and requires replacement. If the drum is NOT rotating while displaying this error, then the Central Control Unit should be replaced.

Whirlpool Duet Sport Model WFW8300SW0 basket won't

The following list of codes indicates an electronics communication problem with the washer: - Duet HT washer - F01, F03, F06, F11, F23, F24, F27, F28, F29, F30, F31, F32, F35, F42, F61, F62, F63, F64, F65, F70, F71, and F99

If Pause/Cancel does not work:
  1. Unplug washer or disconnect power for one minute.
  2. Plug in washer or reconnect power.
  3. Re-select the cycle and press Start.
NOTE: If the error remains on the display, call for service.

I would first replace the door latch/lock assembly, a number of users have and it fixed the F-11 error code completely. Its the cheapest part for this problem.

Hope helps.

F70 Message appears and dryer stops WORKING

The F70 error apparently is a design flaw that happens to many of these machines in this series. It has something to do with a failure of the components to communicate with each other. The main circuit board most likely needs to be replaced hope this helps

Can anyone tell me what an F70 code is? When I push the start button it beeps at my twice and then in about 30 seconds I get a long beep and the error code F70 is on the display. Thanks in advance for your...


F70 error code indicates 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

Thank you !!
