Displaying the code on Ariston without a display

A washing machine with a display communicates with the user by displaying information on it.

What is it about?

Let's decipher the code

Error F12 is one of the most serious. In 95% of cases, it is the result of very serious problems that have arisen in the electronic or electrical circuit of the washing machine. How is this error interpreted? A it stands for this: it is impossible to interact between the control panel display module and the electronic module that controls the entire washing machine.

Unfortunately, most often this error is initiated not even by the electronic controller, but by the display 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 code F12 on the display, or transmits the specified code using the control panel indicators.

Troubleshooting

After studying the decoding of the F12 code, do not rush to become discouraged, although you can already look for the phone number of a good technician in your business card holder. First try to check if the cause of the F12 error is a local failure in the control board. To do this, you need to restart the washing machine three times, pausing for 7-10 minutes between shutdowns.

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

At the bottom of the washing machine body, in the left corner near the back wall, there is a fairly large block, to which there is a bundle of wires; this is the control module.
Without removing the wires, we remove the module from its mounts and photograph it so that we can put it back later.
We disconnect all the chips with wires, put the electronic module aside, after which we get ready and take the part to the workshop.

You may ask, why remove the electronic module yourself if there is no way to repair it yourself? Well, firstly, not all handicraftsmen are unable to repair modules at home, and secondly, even if you have a technician test and repair this part, you will at least save some money on calling a technician and dismantling the part . At current prices, calling a technician and dismantling the electronic module costs from 8 to 33 dollars, depending on the region.
