Professional Repair Guide

What is this symptom?

Is your Siemens Dishwasher not filling with water during the wash cycle? This issue may be accompanied by an error code such as E:32-00. Common causes include a closed water supply valve, a kinked inlet hose, or a clogged filter. Troubleshooting these issues can help restore functionality to your appliance.

Urgency: Medium

Important Tips for Siemens Models

  • Official troubleshooting emphasizes checking water supply valve, hose kinks, low water pressure, and inlet filter blockage.

Possible Causes

Water supply shut‑off valve closed or insufficient water flow to machine

How to Identify: Dishwasher shows no water, check that the external tap feeding dishwasher is open and water flows from household supply.

Part: Water supply valve / household plumbing

Kinked or twisted inlet hose preventing water flow

How to Identify: Visual inspection reveals bends or kinks along hose between dishwasher and water supply, preventing flow.

Part: Water inlet hose

Clogged inlet filter at hose connection

How to Identify: Slow or no water into dishwasher despite supply valve open; debris/limescale in small mesh filter at hose connection.

Part: Inlet filter mesh

Faulty or failing water inlet valve

How to Identify: No water enters even with supply properly open, hose clear, and inlet filter clean; electrical issue at valve likely.

Part: Water inlet valve (solenoid)

Activated Aquastop safety mechanism blocking supply

How to Identify: After leak detection or block, machine stops water intake entirely; Aquastop triggers and valve stays closed.

Part: AquaStop inlet hose assembly

Faulty float switch / level sensor signals water present

How to Identify: Dishwasher thinks water level is sufficient, so inlet valve doesn’t open; may hear pump sounds without filling.

Part: Float switch/pressure sensor

DIY Solutions
