Miele Dishwasher: water accumulation
What is this symptom?
Experiencing water accumulation in your Miele dishwasher? Excess water pooling at the bottom after a wash cycle indicates a drainage issue. While a small film of water is normal, significant standing water not draining can lead to odors and signal faults. Common causes include clogged filters, blocked drain hoses, or issues with the sink drain. Addressing these problems promptly can help maintain your dishwasher's efficiency.
Important Tips for Miele Models
- Miele official support specifically instructs cleaning the filter combination and checks of non‑return valve and drain pump when water remains after cycle.
- Some Miele models retain a small amount of water by design to keep seals moist; excessive water indicates a fault. (HomeGearGeek
