Professional Repair Guide

What is this symptom?

Urgency: High

Important Tips for Bosch Models

  • Bosch repair guides specifically mention checking clogged screens in inlet hose and inlet valve assemblies as common causes for unintended filling.
  • Bosch official troubleshooting does not list continuous fill explicitly, but inlet valve issues are implied as fill control problems.

Possible Causes

Faulty or stuck water inlet valve (fill valve)

How to Identify: Machine keeps filling regardless of cycle stage; valve stays open even when control signals to stop.

Part: Water inlet valve

Clogged screens/filters in fill hose or inlet

How to Identify: Partial obstruction often leads to misreading water flow; stripping screens may be visible when hoses removed.

Part: Inlet filter screens

Control board or sensor error causing misread water level

How to Identify: No mechanical blockages or valve faults found; error codes displayed or erratic behavior.

Part: Control electronics / pressure sensor

Washer won’t stop filling with water. It fills and drains for the entire cycle. Door won’t unlock at the end because there is still water inside.

Check the water inlet valve; clean or replace it if necessary.
