The Ariston SM display displays error code F12 until the tank is completely filled with water. Often the machine does not take water at all, sending a corresponding signal. This error is preceded by one notable sign - the water intake valve begins to function irregularly, making unusual sounds. Let's figure out what error F12 means on an Ariston washing machine and clarify the list of faults that cause it.
How is error code F12 recognized?
Ariston washing mashines whose models do not have a display signal error F12 as follows:
| model name | signal delivery method |
| "Margarita" | The on/off light starts blinking. The indicator lights up in a twelve-time cycle, followed by a short break. In addition to this, the “Lock” indicator light comes on, the handle clicks and turns in a circular motion. |
| AML and AVSL types | When error F12 occurs, the “Super Wash” and “Delay Timer” light diodes blink, and the “Lock” lamp often lights up. |
| SM Hotpoint ARL, ARSL, ARXL | The “Spin” and “Drain” lamps flash. At the same time, the remaining LED elements simply light up. |
| Aqualtis | With error F12, the temperature lamp flashes at 40 and 45 degrees. |
Note that there is no contact between the indicator system and the control unit. This means that you can solve the problem yourself without calling a specialist.
Decoding the F12 code
Error F12 is a serious one. Almost always it signals serious failures associated with the electronics and electrical circuit of the Ariston washing machine. What does the error mean, how can it be deciphered?
The explanation is simple - there is no possibility of interaction between the control panel display module and the electronic unit responsible for the operation of the entire Ariston unit.
Much to our chagrin, often the F12 error is initially generated not by the electrical controller, but by the module indicator. The reason is that it is not able to interact with the main “brain” of the Ariston machine to coordinate its own commands. Therefore, it begins to block the working stages, displaying error F12 on the screen, or sends the named code using panel indicators.
How to fix a breakdown at home
To resolve error F12 yourself, you can try the following options:
- Error F12 can be reset by disconnecting the Ariston machine from the electrical network. If a normal failure occurs in the system, then after turning it back on, the washing machine will work normally. Such actions are performed at least three times, pauses between test runs should be from seven to ten minutes;
- check the contact group going from the indicator element to the electronic controller. If loose wires are found, simply install them in their places.
There is practically no chance that such actions will help you resolve the F12 error, but it’s worth a try.After this, the panel responsible for the control, the electrical wiring that powers it, and after that the electronic modular device of the Ariston washing machine itself are checked. Traditionally, they start with what seems simpler - wires and a board. But if there are no positive results, you should think about calling a specialist.
Problem with the board
Experts say that up to eighty percent of faults when error F12 is detected are related to the board. In this case, the Ariston washing machine immediately reveals the problem without starting the washing process. What to do in this case?
- if the board of an Ariston machine fails, it should be “reflashed”;
- failed triacs or diodes are replaced with new analogues;
- if the tracks are burned out, all elements of the circuit are cleaned, the contact points are resoldered;
- In the event of a processor failure, the management module will have to be completely replaced.
Module failure
The main reasons for its failure are similar to board failures; they should be eliminated using the same methods.
Problems with wires
The wiring connecting the display and control units of the Ariston washing machine could have burned out. The causes, as a rule, are power surges or ubiquitous rodents. Defective areas are cleaned and soldered, and new wiring is installed.
Other reasons for the F12 signal
Often everything happens in a trivial way - moisture gets on the electronics of the Ariston washing machine. This is especially true for models that have a vertical loading method. This can happen when heavy items are washed in the machine - jackets, small carpets, rugs. The Ariston washing machine is not able to wring out such items; when they are removed, water floods the machine and error F12 appears.As a result, either the control module of the Ariston unit or the display unit fails.
In addition to the listed problems, the Ariston machine may also have hidden faults. Our code cannot detect them, but only they will provoke electronic failures. To detect these breakdowns, you must have sufficient experience in performing repair work.
For these reasons, many craftsmen do not advise attempting to perform repairs on their own.
Tools
To repair your Ariston machine yourself you will need:
- Screwdriver Set;
- pliers;
- tester who will have to check every element.
Sequence of repair work
Naturally, calling an experienced technician from the service center will help save you both free time and your own nerves. If you want to work on your own, you can find and dismantle the module yourself, taking it to a specialist for repair. This is done this way:
- The rear panel of the Ariston washing machine is removed.
- In the bottom part of the case, in the corner on the left, there is a decent-sized block mounted, wires go to it. This is the module responsible for the management process.
- We remove the Ariston machine module without disconnecting the wiring. It should be photographed so that later the installation can be carried out correctly.
- Having disconnected the chips, we take the module to the workshop.
Is there a need to remove the module yourself if it still has to be repaired in a workshop? Firstly, this way you can avoid unnecessary expenses. Secondly, there will always be craftsmen who will do such work with their own hands.
Conclusion
The first error message F12 may appear at various stages, but at each restart it will appear immediately.
As it turned out, error F12 is quite serious, as it is a consequence of a failure of electrical and electronic circuits. Some problems can be eliminated on your own, but if you have not dealt with Ariston CM repair before, we recommend contacting an experienced specialist who will quickly find the problem and fix the malfunction.
