Miele Dishwasher: not filling with water

Professional Repair Guide

What is this symptom?

Is your Miele dishwasher powering on but not filling with water? If you're hearing sounds without water flow, it could be due to common issues like a closed water supply valve or a faulty inlet valve. This guide will help you diagnose and fix the problem effectively.

Urgency: Medium

Important Tips for Miele Models

  • Miele support lists error codes F12, F13, F15 related to water inlet/fill faults that can indicate issues with water intake.

Possible Causes

Water supply valve closed or supply hose blocked/kinked

How to Identify: Check that the shut‑off valve under the sink is fully open and the inlet hose has no kinks or visible blockages.

Part: Water supply line/valve

Faulty or clogged water inlet valve

How to Identify: Dishwasher makes sound of starting but no water enters; testing the inlet valve for continuity and ensuring supply pressure reaches the valve help indicate failure.

Part: Water inlet valve

Stuck or faulty float/float switch

How to Identify: Float inside tub does not move freely or stays in raised position; may falsely signal full tub preventing fill.

Part: Float/Float switch assembly

Door not properly latched or door switch failure

How to Identify: Dishwasher does not click securely shut; door switch may not engage and fill cycle won’t start.

Part: Door latch/door switch

Control board/electrical signal issue

How to Identify: Dishwasher shows erratic operation, skipping fill phase, or error codes that persist after basic checks.

Part: Control board/Timer circuit

DIY Solutions

Check and ensure water supply is on

Easy 5-10 minutes
  1. Locate the shut‑off valve under sink to dishwasher and ensure it is fully open.
  2. Inspect the inlet hose for kinks or visible damage along its length.
  3. Straighten any kinks or replace the hose if visibly damaged.
⚠️ Safety First: Ensure water supply is off if disconnecting hose to inspect or replace.

Inspect and clean float assembly

Moderate 10-20 minutes
Tools Needed: Screwdriver
  1. Open dishwasher and locate float mechanism (usually near front corner of tub).
  2. Lift float up and down to ensure it moves freely without obstruction.
  3. Remove debris around float/float well; reassemble and test cycle.
⚠️ Safety First: Disconnect power to prevent machine start during inspection.

Test door latch engagement

Moderate 10-15 minutes
Tools Needed: Visual inspection, possibly multimeter
  1. Close dishwasher door and ensure it makes a solid click.
  2. If door doesn’t latch securely, inspect latch for visible wear or misalignment.
  3. Test door switch continuity if comfortable using multimeter; replace latch/switch if defective.
⚠️ Safety First: Unplug dishwasher before accessing internal door components.
