Before the Error code F70 appears, the dryer stops, gives one beep, blinks, and stops working. It is mainly due to inadequate or unavailable connections between the electronic components.
What is error F70 caused?
It is due to the lost connection between the control printed circuit and the console electronics. This is usually due to severe breakdowns, which at a time can be resolved by replacement.
The first action to take is rebooting the device. To do this, disconnect the cord and plug it in 10 – 20 minutes. After this, the device will run a self-test and eliminate the code if it’s a random problem.
Causes of malfunction and methods for their elimination
A loose or weak connection between the main elements is the primary cause of error F70. To reset the error, examine the wiring at the main modules and tighten any loose connections.
If the wiring is OK and error code F70 is still appearing, check the wires separately. You can do this visually or with a multimeter. Solder, twist or replace the damaged cables.
Breakage of the console board
Blinking start and pause buttons, lightening settings lamps, lines on a digital display are signs of its defect. Moreover, the dryer behaves like this periodically: after the disappearance of error code F70, the Whirlpool dryer displays it again after a certain period. The solution is to replace the user interface control panel. To access it, follow the instructions:
- switch off the equipment (unplug it);
- untwist the screws on the back of the top panel;
- lift the end of the cover, slide it back and remove.
Install a new element (its cost depending on the brand is $ 153 – 195) and reassemble the dryer in the reverse order. After that, error F70 should disappear. If it remained, then the problem is in the central control unit.
Failure of the central module
The fact that it is faulty is indicated by a sound signal, interruption of the cycle, and error code F70. Even if everything is normal visually (there are no burn marks and reflowing), the electronic unit requires reinstallation.
To access the central module, particular actions have to be taken. After removing the top panel, then follow the procedure as described below:
- unscrew the support bracket above the drum;
- unfasten the latches;
- disconnect all connections;
- remove the main circuit board.
