Miele Dishwasher: inlet hose failure

Professional Repair Guide

What is this symptom?

Experiencing issues with your Miele dishwasher's inlet hose? Common problems include kinks, cracks, and leaks that prevent proper water flow. You may see error codes indicating water inlet faults or notice visible leakage around hose connections. Addressing these issues promptly is essential for optimal dishwasher performance.

Urgency: Medium

Important Tips for Miele Models

  • Miele documentation specifically warns that kinked inlet hoses can weaken plastic and require replacement.
  • Miele support describes cleaning the plastic filter and seal at the water intake valve as part of official troubleshooting.

Possible Causes

Kinked or twisted inlet hose restricting water flow

How to Identify: Visible kinks, loops, or bends in the inlet hose behind the dishwasher; dishwasher stops filling or shows inlet error mentions hose restriction.

Part: Water inlet hose

Damaged or cracked inlet hose causing leaks

How to Identify: Wet floor or moisture under dishwasher near hose connections; visible cracks or softened/deteriorated hose rubber.

Part: Water inlet hose

Clogged inlet filter at hose connection

How to Identify: Dishwasher displays inlet error, and cleaning the small mesh filter at the hose connection improves filling speed/flow; debris visible in filter.

Part: Inlet filter screen

Loose or improperly tightened hose connection

How to Identify: Water drips from connection point; tightening the connection reduces leak temporarily.

Part: Hose fittings and seals

Low household water pressure preventing adequate flow

How to Identify: Dishwasher fills slowly or not at all; faucets also show low pressure; inlet pressure below Miele’s recommended threshold.

Part: Water supply system
