Miele Washing Machine: not enough water

Professional Repair Guide

What is this symptom?

Experiencing insufficient water fill in your Miele washing machine? This issue often causes the drum to remain empty or the water level to be lower than expected during wash cycles. Common causes include water supply problems, faulty inlet valves, or blocked filters. Addressing these issues promptly ensures optimal washing performance.

Urgency: Medium

Important Tips for Miele Models

  • Miele washers may display error codes such as F20 indicating water fill problems.

Possible Causes

Water supply issue (hoses or taps)

How to Identify: Check if water taps supplying the machine are fully open; visually inspect hoses for kinks, bends, or blockage; if cold/hot hoses pinched behind machine.

Part: Water inlet hoses and household water supply

Faulty water inlet valve
