Error F12 on Ariston washing machine

Error F12 on the Ariston washing machine most often appears until the water is completely filled into the tank. Often, the machine does not start to draw water at all, giving the appropriate code to the display. The error F12 is preceded by a rather remarkable symptom - the inlet valve starts to work hysterically, making specific sounds. About the F12 error on the Ariston brand washing machine and about the malfunctions that cause it, read this article.

Display code on Ariston without display

A washing machine with a display communicates with the user by displaying information on it. But if the washer does not have a display, it can also tell a lot, through the light indication, you only need to correctly recognize this indication and draw the appropriate conclusions. What is this about?

• The Ariston washing machine of the “ancient” Margherita line begins to blink intensively 12 times with the indicator of the power button, then takes a break for up to 15 seconds and repeats blinking again, while the lock indicator will light constantly.
• The Ariston AVSL washing machine blinks with an LED that indicates the “Super Wash” mode, as well as a delay timer indicator, and the “key” or “lock” LED will very often blink.
• On Hotpoint-Ariston ARXL, ARSL, ARL washers, this error is displayed on the control panel of the Blinking and Spin indicators blinking. Moreover, in some cases there is an additional sign in the form of burning indicators of functions, and they all burn together.
  
• Hotpoint-Ariston Aqualtis will be notified of the F12 error through a third and fourth temperature light (40⁰C and 50⁰WITH).

To correctly identify the code that a washing machine passes to you without a display, you need to carefully monitor it after reconnecting. Usually, the indication code is repeated many times, you just need to count the blinks of various bulbs.

Decrypt the code

Error F12 is one of the most serious. In 95% of cases, it is the result of very serious malfunctions that have occurred in the electronic or electrical circuit of the washing machine. How is this error decrypted? BUT it is decrypted as follows: interaction between the display module of the control panel and the electronic module that controls the entire washing machine is impossible.

Unfortunately, most often this error is triggered not even by an electronic controller, but by an indication module, since it cannot communicate with the “brain” of the washing machine and coordinate its actions. Accordingly, it blocks the operation of any washing programs and displays the F12 code on the display, or transmits the specified code using the indicators on the control panel.

Troubleshooting

Having studied the decoding of the F12 code, do not rush to become discouraged, although it is already possible to search for a phone of a good master in your card holder. First try to check if the cause of the F12 error is a local fault in the control board. To do this, you need to restart the washing machine three times while holding pauses for 7-10 minutes between shutdowns.

In this case, you need to disconnect the machine every time from the network, not only from the button, but also by disconnecting the power cord of the washing machine from the outlet.

The chances that this will help not so much, but worth a try. Next, you need to check the display board of the control panel, the wiring that powers it and the electronic module itself. By tradition, let's start with the simpler way - by checking the display board and wiring. How to do this is described in the article. Error F06 in Ariston washing machine, we won’t repeat ourselves, but immediately go to the electronic module.

If, after checking the rest of the electrics, you are convinced that the error code F12 leads to the control module, feel free to call the wizard. This will save you a lot of time, and at the same time nerves.But if you really want to “dig deeper” with technology, find and remove the control module in order to transfer it to the master for repair. You can do this as follows.

1. We remove the back wall of our "home assistant" brand Ariston.
2. In the lower part of the washing machine’s case in the left corner near the rear wall there is a rather large unit, to which there is a bundle of wires, this is the control module.
3. Without removing the wires, remove the module from the mounts and photograph it, so that later you can put it back.
   
4. We disconnect all the chips with wires, remove the electronic module to the side, after which we assemble and carry the part to the workshop.

You may ask, why remove the electronic module yourself if there is no way to fix it yourself? Well, firstly, by no means all handicraftsmen are able to repair modules at home, and secondly, even if you master and test this part, you will at least save some money on calling the master and dismantling the part . At current prices, calling a wizard and dismantling an electronic module costs between $ 8 and $ 33, depending on the region.

So, to summarize our story today. Error F12, as it turned out, can be very serious, because it causes breakdowns in the electrical and electronic communications of the washing machine. Some problems can be solved with your own hands, but if you have never repaired washing machines and any electronics at all, it is better to call the master and explain to him in detail what the problem is. Most likely, a good master will find a way to help you. Have a good repair!
