Miele Dishwasher: odor

Professional Repair Guide

What is this symptom?

Are you experiencing unpleasant odors from your Miele dishwasher? Common smells include musty, rotten, fishy, and sour odors that can occur during or after operation. Even if your dishes appear clean, these odors may linger when you open the door or when the dishwasher is idle. This problem is often caused by accumulated food particles and debris in the filter, leading to a less than fresh kitchen environment.
