Miele Dishwasher: all lights flashing

Professional Repair Guide

What is this symptom?

If your Miele dishwasher has all lights flashing simultaneously, it indicates a general fault condition. This can occur after starting a cycle or during operation and may be accompanied by beeping. Common causes include accumulated dirt, unresolved fault states, or masked specific error codes. Understanding these can help you troubleshoot effectively.

Urgency: Medium

Important Tips for Miele Models

  • Official Miele guidance for all lights flashing focuses on cleaning non‑return valve, drain pump, and spray arms; if issue persists, contact Miele Service.
  • Community reports suggest possible F01 (sensor) or control board faults can cause all lights flashing, but not officially documented by Miele.

Possible Causes

Accumulated dirt/clogs causing general fault

How to Identify: Lights flash without specific fault code; machine may stop mid‑cycle; buildup visible in removable components

Part: Filter combination, non‑return valve, drain pump, spray arms

Stored or unresolved general fault state requiring reset

How to Identify: Lights flash collectively even after cleaning components; cycle doesn’t start or resume; power cycling may reset condition

Part: Control system / internal memory

Underlying specific error codes masked by general flash mode

How to Identify: Dishwasher may have logged specific faults (e.g., F11, F12 retrievable via service tool or display sequences; general lights flash until resolved

Part: Various error‑related components (e.g., water inlet/drain, waterproof system)
