Electronic models of washing machines Ariston and Hotpoint-Ariston show errors F09 on the display. On the electromechanical SM, the indicators on the front panel light up.
When DTC F09, the “Delay Timer” and “Extra Rinse” lamps flash, which means a malfunction (error) in the ROM memory.
Ways to resolve the error
Error code F 09 in SM Ariston is displayed on the display panel when there is a problem with the electronic controller or if there is a memory violation in the microcircuit.
It’s not always possible to remove the error on our own, so let's start with simple steps:
- A system failure can be fixed by rebooting the washer. To remove the error, unplug the machine from the network for 15-20 minutes. If the trouble code lights up again after connecting, try the other steps.
Before starting repair of the controller, you need to make sure that it is malfunctioning. To do this, conduct an autotest - system diagnostics to check the functions of the washing machine.
Typical faults and self repair
If you did a check and the problem is really in the controller, how do you fix the problem? Next, you will find out why SM Ariston may throw an F 09 error.
We give an example of typical problems, tell you what to do and how to fix the breakdown.
The washing machine does not turn on or off
- Check the connection of the line filter S1, there may not be enough voltage for the washing machine to function properly.
- Inspect the power switch, maybe solder is damaged at connector S1.
- Pay attention to the body of the power switch. If it moves away from the controller board, the latter is shifted to the side, which prevents normal contact. Put the case back in place and fix it with glue or a clamp.
- Check the power supply elements: fuse, stabilizer U1, filter capacitor, etc. Often, due to moisture, a similar malfunction occurs. If the actions do not help, you will have to replace the board.
CM does not execute the program
If the Ariston or Hotpoint Ariston washer does not execute the command, the reason may be a violation of the contacts.
- Remove the program selector cover.
- Strip the pads and contacts on the control board.
- Fix the cover in place with paint.
- Additionally, use a multimeter to check the weight resistors. The indicator should be 100 ohms.
- If the cause of the malfunction is in the processor's Flash memory, you will need to replace the chip.
The device controlled by the triac does not work
What does it mean: the motor and other elements of the Ariston machine either do not work, or they are constantly supplied with voltage.
If the elements themselves function normally, inspect their wiring to the control board, triacs, check the contacts. A short circuit could cause some wires to burn out, so they need a replacement.
If the recommendations helped, then you managed to reset the error with SM Ariston.
The control board is a complex element of the washing machine. If F09 is displayed again, it is better to contact the wizard.
