If your SM Ariston (Hotpoint Ariston) shows error F18 on the display, there are problems with the electronic controller. On models with electronic control, error code F18 will be displayed on the display. Electromechanical cars will signal a problem with a 12-fold blinking of light bulbs.
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 the choice of washing programs.
- Displays the operating mode of the washer on the panel, display.
- Manages the drain and water intake valves.
- It controls the operation of the motor of the washing machine, which means it controls the speed of rotation of the drum.
- It controls the pump, distribution valve, pressure switch, UBL device.
- Responsible for turning on and off the SM Ariston.
If you need to conduct an auto test of the machine, the controller will also help.
Symptoms
What does the error F 18 mean, you understand. Now you need to understand the causes of the trouble code. Pay attention to the main signs of a failure of the electronic controller, in which the Ariston washing machine can generate an F 18 error:
- The engine stopped working properly. Its speed is not justified: it’s too high, then low.
- The washing program does not start, the drum does not rotate.
- The spin mode does not work, the water just accumulated, as it immediately begins to merge.
Due to the ingress of moisture or foam during operation of the Ariston (Hotpoint Ariston) washing machine, the board suffers in the first place. Which means inconsistency or complete failure - then the part needs to be replaced.
Troubleshooting Options
Try to reset the F18 error by rebooting. Disconnect the machine for 15-20 minutes, then turn it on. The error disappeared - the cause was a system failure.
What to do if the code is on again? Checking other elements of the washer will help solve the problems.
Before correcting a problem with the controller, you need to check other parts of the Ariston SMA, which may be the cause of the malfunction. To do this, use a multimeter and alternately ring the motor, heater, pump - all that causes suspicion. If possible, conduct an autotest of the machine.
The electronic controller is difficult to build, and it’s also not cheap. Therefore, it is sometimes better to contact a service center.
