What Does Error F08 Mean?
The Ariston dishwasher error F08 indicates a temperature timeout fault, where the appliance cannot sense or reach the required heating temperature in time. This often points to issues with the heating system, such as a failed heating element, thermostat, or NTC sensor. Users may notice the dishwasher halting mid-cycle, failing to progress past the water heating stage, or displaying LED 4 while others remain off. If noticeable noises arise during operation, it suggests a malfunctioning drain pump.
Common Symptoms:
- Dishwasher stops mid‑cycle and displays F08 or corresponding LED pattern (LED 4 on with others off).
- Cycle does not progress past water heating stage.
- Heating does not occur within expected timeout period.
Possible Causes
- Failed or unresponsive heating system component (heater element, thermostat, NTC temperature sensor) (medium)
- Heating relay or control circuit issue causing thermostat/heater to not activate properly (medium)
