Miele Dishwasher: not cleaning

Professional Repair Guide

What is this symptom?

Experiencing issues with your Miele Dishwasher not cleaning effectively? If your dishes come out with food residue, spots, or unclean surfaces after a cycle, you're not alone. This common problem can stem from clogged filters, improper detergent, or even faults in the water pump or heating element. Understanding these causes is essential for getting your dishwasher back to optimal performance.

Urgency: Medium

Important Tips for Miele Models

  • Miele dishwashers do not require pre‑rinsing; only large food particles should be scraped to allow sensors to detect soil properly.
  • Filter maintenance is often prompted by a display message (e.g., after ~50 cycles); follow manual instructions to clean to maintain performance.

Possible Causes

Clogged or dirty filter reducing water flow

How to Identify: Food particles visible on filter, slow draining water, dishes still grimy

Part: Filter assembly

Improper detergent type or dispenser malfunction

How to Identify: Detergent not dispensing fully or prematurely dissolves, dishes remain soapy or dirty

Part: Detergent dispenser system

Low water temperature or wrong cycle selection

How to Identify: Using low-temp or quick/eco cycles with heavy soils not removed

Part: Wash program/temperature control

Water pump or heating element faults

How to Identify: Dishwasher fills but water isn’t projected with force; water not reaching proper temp

Part: Water circulation pump/heating element
