Miele Dishwasher: error code F13

Professional Repair Guide

What is this symptom?

If your Miele dishwasher is showing error code F13, it means it's having trouble filling with water in the expected time. This can cause interruptions mid-cycle or prevent the wash from starting altogether. Understanding the causes and potential fixes can help you get your appliance back to working order efficiently.

Urgency: Medium

Important Tips for Miele Models

  • Official Miele documentation specifies the F13 error refers to a blocked or restricted water inlet and provides steps for cleaning the inlet filter and ensuring valve is open.
  • Some community sources note additional possible causes like internal sensor faults or pump issues beyond official documentation.

Possible Causes

Blocked or restricted water inlet supply

How to Identify: Error appears at start of cycle; visual inspection shows clogged inlet filter or hose kinked; inadequate water flow at hose end.

Part: Water inlet filter and hose

Water shut‑off valve not fully open or low house water pressure

How to Identify: Water valve not fully open; weak stream from faucet when hose removed; error persists even after inlet filter cleaning.

Part: House water supply valve / plumbing

Malfunctioning water inlet valve

How to Identify: Dishwasher still fails to fill with water after inlet filter cleaning and good house water pressure; valve stuck or fails continuity on multimeter.

Part: Water inlet solenoid valve

Internal flow sensor or pressure switch issue

How to Identify: No obvious external causes found, and diagnostics indicate sensor failure via multimeter or test cycle.

Part: Flow meter / pressure sensor
