Often, a change in the firmware of an automatic washing machine is assigned only when the memory module fails, which is extremely rare. The firmware process itself is simple and will not take a lot of time, but there is a risk of damaging the memory module.
It is necessary
- - Washer;
- - programmer.
Instructions
Step 1
First of all, it is worth asking yourself whether you really need to overwrite the machine memory sector? Often, the problem lies not in the malfunction of the memory module, for that there are other reasons and solutions, respectively, will be completely different.
Step 2
If you nevertheless decide to flash the module, do not forget that this operation is performed differently for each washing machine. Often it all depends on the brand and model of equipment that is installed in your home. The firmware version also plays an important role. The most optimal option is to perform the flashing operation through special sockets (connectors), which not every model has.
Step 3
If there are no such connectors, the operation becomes much more complicated. Recently, there has been a tendency to integrate a memory module into the processor of a washing machine. Thus, at this stage, repairs are only possible in a service center, which, most likely, will cost significantly more. To perform memory flashing through the processor, you need to have special equipment, which costs a lot of money.
Step 4
Now you need to open the instruction manual, which usually contains the connection diagram of the indoor units. If you have not found schematic drawings, you can search for them on the official sites. To do this, in the search window (as a rule, the upper right corner), you need to enter the model of the car and press the Enter key. Select your washing machine from the search results and go to the Download section.
Step 5
In this section, you need to find the manual (Manual) and download it by clicking the corresponding link. The downloaded file will open through an e-book reader (Adobe Reader or Foxit PDF Reader).
Step 6
De-energize the washing machine and proceed to disassemble the outer casing. Using the diagram from the electronic document, find the memory bar and try to unsolder it using a thin-tip soldering iron.
Step 7
The extracted module is attached to the programmer, which initially reads the data, and then carries out the firmware. To install a new firmware version, you need to download the corresponding files from the same site.
Step 8
After the completion of the firmware operation, it remains to solder the circuit to its original place and assemble the body of the washing machine.
