Miele Dishwasher: not drying plastic properly

Professional Repair Guide

What is this symptom?

Are you noticing that your Miele dishwasher isn't drying plastic items properly? This common issue often results in wet plastic after a full cycle, especially evident in eco or low-heat settings. While ceramics and glass may dry well, plastics can remain damp due to their low thermal mass and inadequate rinse aid usage. Understanding the causes can help improve drying performance.

Urgency: Low

Possible Causes

Low thermal mass of plastic items

How to Identify: Only plastic cups and containers remain wet while ceramic/glass are relatively dry

Part: Dishware material property

Incorrect cycle selection (Eco/short cycles)

How to Identify: Using eco or short cycles that limit drying time and temperature; wet plastic at cycle completion

Part: Control panel/cycle settings

Insufficient or no rinse aid use

How to Identify: Rinse aid reservoir empty or set low; water clings to surfaces

Part: Rinse aid dispenser
