The display of error codes on various models of Whirlpool appliances signifies different things. When error f70 appears on a Whirlpool dryer, it means the appliance has detected a failed connection or communication between the user interface and the main control board. The error code could also be a malfunction of the control board or touchpad/user interface board.
How to Repair the f70 Error Code
The first thing you want to do is make sure when your Whirlpool dryer displays the f70 error that it isn’t merely a malfunction of the machine’s control board or touchpad. This could have been caused by a power surge; resetting your washer/dryer will take care of this. Unplug the power cord from the socket for about 15-20 minutes, plug it back in, then switch on the power button.
After the reset, the device usually runs a self-test, eliminating unexpected problems. If that doesn’t happen and the error code still appears, inspect the electronic components of the machine.
Wiring Harness/Connections
Central Control Unit and User Interface
A loose connection or poor communication is a standard answer to this error code. Check the connections on the main control board and the user interface board.
To do this, disconnect each board from the surrounding latches and inspect them closely. Pay attention to the wires, pins, and main cables connecting the console to the control module, checking for a corroded or broken wire.
If you see any such wire, it has to be replaced. If a visual inspection reveals nothing, try using a multimeter to locate wiring damage. Do the wires look okay? Then proceed to examine the electronic boards.
Failure of the Main Control Board
Sound signals, an interruption of a cycle, and the display of the f70 code are usually signs of failure of the Whirlpool duet central control unit. These signs indicate a need to replace this electronic unit. It costs about $113-$330, depending on the model or brand.
To access your device main control console:
- Cut off the power supply
- Remove the top panel
- Unscrew the support bracket above the drum
- Unfasten the latches
- Disconnect all connections
- Remove control board
Faulty User Console
The breakage/damage of this interface could also be the reason for the f70 error. Lines on the device’s screen, blinking start and pause buttons, lightening settings lamps, and periodic flashing of the error code, all signal a need to replace the user interface.
To remove the top panel and access your device’s interface:
- The washer/dryer shouldn’t be plugged
- Unscrew the screws at the back of the panel
- Lift the cover, slide back and remove
Replacing this element costs about $153-$195, depending on the washer’s model.
Unfortunately, a failure/fault in either of these boards means a replacement as they can’t be fixed. When both boards are damaged, and your appliance has stopped working, it’s advised to get a new Whirlpool washer rather than having the parts replaced.
If you have questions regarding parts repair or your machine’s model number, you can chat with the company’s customer service.
