Miele Dishwasher: all lights flashing
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.
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)
