CODE ERROR : 4 ARISTON DISHWASHER LST 329 - Dishwashers

This error message indicates that an anti-flooding overflow is taking place. This may be related to a failing rubber gasket around the dishwasher door, a defective water inlet valve, or a faulty float switch or sensor. The float and switch sensor is activated by pressure and if faulty will need to be replaced.Dec. 21, 2020

Reading the error code

The fault on the appliance is signalled via:

1. the continuous rotation of the selector knob
2. the action, for the first 4', of the electrovalve and the drain pump
3. the door becomes unlocked
4. the led flashes: the number of flashes indicates the fault code; the code should be read as follows:
· each fast flash (2/3 flashes of the led very close together) represents one code value
· the fault code is evaluated by counting the number of flashes occurring at 3/4" intervals from one another
· stop counting when the washing machine waits the equivalent of approximately 8/9" between flashes
· the procedure is repeated by the appliance cyclically

After you determine which the alarm code appeared we will able specifically to help you.

If flashing any of the 4 LEDs (see picture) means that the dishwasher discovered a malfunction. Depending which combination of LED flashes (one LED, two LEDs, three LEDs or all four LEDs) indicates the specific error code.
