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.

  • 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)
