Miele Dishwasher: not circulating water

Professional Repair Guide

What is this symptom?

Experiencing issues with your Miele dishwasher not circulating water? This leads to inadequate cleaning as water fails to spray from the arms. Common culprits include a blocked circulation pump or clogged spray arms, which can also trigger error codes like F78. Don't let dirty dishes pile up—understanding the problem is the first step towards a solution.

Urgency: Medium

Important Tips for Miele Models

  • F78 error indicates blocked or stuck circulation pump; official guidance suggests soaking warm water with rinse aid and restarting, and if unresolved, contact service
  • Official guidance for spray arm blockage faults includes cleaning and ensuring arms rotate freely; proper loading to prevent blocking is important

How to Identify: Insufficient water level at start of cycle, slow fill or partial fill, weak spray throughout wash

Part: Water inlet system (hose, valve)

Electrical or wiring fault to circulation pump
