If your SM Ariston (Hotpoint Ariston) shows error F18 on the display, there are problems with the electronic controller. On models with electronic control, the error code F18 will be displayed on the display. Electromechanical machines will signal a problem by flashing 12 times.
Thanks to the self-diagnosis system of Ariston washing machines, you can recognize and understand how to fix the problem.
Controller functions
To find out how to fix the breakdown and remove the error, you need to figure out why an electronic controller is needed.
- Responsible for selecting wash programs.
- Displays on the panel, the display the operating mode of the washing machine.
- Controls the drain and water intake valves.
- Controls the operation of the washing machine motor, which means it controls the speed of rotation of the drum.
- Controls the pump, distribution valve, pressure switch, UBL device.
- Responsible for turning on and off SM Ariston.
If you need to autotest the machine, the controller will also help with this.
Symptoms of a malfunction
What does error F 18 mean, you understand. Now you need to figure out the reasons for the appearance of the fault code. Pay attention to the main signs of a breakdown in the electronic controller, in which the Ariston washing machine may generate an F 18 error:
- The engine has stopped working properly. Its speed is not justified: either too high or too low.
- The washing program does not start, the drum does not rotate.
- The spin mode does not work, the water has just accumulated, as it immediately begins to merge.
Due to the ingress of moisture or foam during the operation of the Ariston washing machine (Hotpoint Ariston), the board first of all suffers. Which means inconsistency or complete failure – then the part needs to be replaced.
Troubleshooting options
Try resetting the F18 error by rebooting. Unplug the machine for 15-20 minutes, then turn it on. The error disappeared – the reason was a system failure.
What to do if the code is on again? Checking other elements of the washer will help solve problems.
Before fixing a problem with the controller, you need to check other Ariston SMA parts that may be causing the malfunction. To do this, use a multimeter and alternately ring the motor, heating element, pump – everything that is suspicious. If possible, perform a self-test of the machine.
The electronic controller is complex, and also expensive. Therefore, sometimes it is better to contact a service center.
