Miele Dishwasher: flashing lights, wet dishes, low water level
What is this symptom?
If your Miele dishwasher is showing flashing indicator lights, leaving dishes wet, and displaying a low water level in the wash tub, you may be facing a water supply issue. Common causes include a faulty water inlet valve, clogged filters, or a malfunctioning drain pump. Understanding these issues can help you troubleshoot effectively.
Important Tips for Miele Models
- Flashing intake/drain or water inlet lights may correspond to specific fault codes (e.g., F12/F13 for water inlet faults) requiring service reference to model manual.
Possible Causes
Water inlet fault or insufficient water fill
How to Identify: Dishwasher doesn’t fill with normal water level at start, intake indicator light flashing or error code related to water inlet (e.g., F12/F13/F15 on Miele models.
Part: Water inlet valve / water supply line
Drain or circulation pump fault causing incorrect water sensing
How to Identify: Flashing intake/drain indicator, poor water circulation resulting in ineffective spray; water level sensor may be affected.
Part: Drain pump / circulation pump impeller
Clogged filters or spray arms reducing water distribution
How to Identify: Poor water distribution observed, low water jets, spray arms not rotating freely; wet dishes with spots.
Part: Filters / spray arms
