If your SMEG LVS1251X1 dishwasher displays an alarm or error code, there is a simple reset procedure.
First method: open and close the door
Open the appliance door, wait a few seconds, then close it again. This is usually enough to cancel a temporary alarm.
Second method: turn the machine off and on
Press the ON/OFF button to completely turn off the appliance. Wait about 10 seconds, then press ON/OFF again to restart it.
After this reset, your machine will resume normal operation and the alarm will disappear.
If the alarm persists after these two actions, consult the error code table in the manual (accessible via the PDF viewer on this page) to identify the specific type of anomaly and take appropriate measures.
