What is this symptom?

Is your Miele Dishwasher showing an intake/drain error with the indicator light flashing? This can result in the appliance stopping mid-cycle, failing to fill with water, or not draining properly.

Important Tips for Miele Models

  • Miele official guidance points to cleaning the drain pump and non‑return valve when intake/drain indicator blinks and highlights that kinks or blockages in the drain hose and deposits can cause the error.
