SM Ariston (Hotpoint Ariston) shows the error F12 on the display before water intake. The malfunction code appears at different stages of washing, but if the breakdown is not eliminated, the error will be displayed on the display immediately after turning on the machine.
On models with electromechanical control, the code will appear on the indicators, which means a serious malfunction.
Code recognition
Washing machines without a display give an F 12 error like this:
What does the code F12 mean, what to do in case of a malfunction? There is no contact between the display system and the control unit. You can try to solve this problem at home.
To fix the problem, read on.
Troubleshooting at home
How to fix the problem in the Ariston washer and remove the error F12:
- Resetting the code will help completely disconnect the machine from the network. The system may have crashed. If so, when you turn on the washing machine will work in normal mode.
- View the contacts leading from the indicator to the electronic controller. If the wires are loose, reinstall them.
What if nothing helps? Try to determine the cause of the breakdown.
Control module
It is believed that 80% of problems with the appearance of the F12 error occur on the board. Then the machine immediately issues a code without starting the wash.
What can be done:
- If the firmware of the board fails, it is necessary to “reflash” it.
- In case of problems with the elements of the board (diodes, triacs), you need to replace.
- If the track burns out on the chip, you will have to strip the elements, solder the contacts.
- A microprocessor failure needs to be replaced by the entire control module.
Display module
The reasons are similar to the malfunctions of the control board, the solutions are the same.
Connecting circuit damage
The wires connecting the control and indication unit could burn out due to power surges, they could be damaged by rodents. Defective contacts can be cleaned and soldered, and wires can be replaced with new ones.
Each item is checked by a tester before repair.
If the repair at home did not return the machine to operability, contact a service center.
