What Does Error F12 Mean?

The F12 error code on your Asko dishwasher indicates a water inlet fault, preventing the machine from filling with water properly. This issue may arise due to a partially closed water supply shutoff, a blocked or kinked inlet hose, or a malfunctioning water inlet valve. Symptoms typically include the dishwasher stopping shortly after starting, often during the initial fill cycle, and insufficient water entering the machine.

Common Symptoms:

  • Dishwasher stops shortly after starting with F12 displayed — typically around initial fill cycle.
  • Insufficient water entering the machine during wash cycle.

Possible Causes

  • Water supply shutoff partially closed or restricted (medium)
  • Inlet hose blockage, kink, or damage (medium)
  • Faulty water inlet valve or flow meter (medium)
