Miele Dishwasher: drain light flashing
What is this symptom?
If your Miele dishwasher's drain light is flashing, it indicates a drainage or intake issue. This often results in the program stopping and water remaining in the basin. Common causes include clogged filters, blocked drain pumps, or kinked hoses. Addressing these issues promptly is essential to restore your dishwasher's performance.
