Bosch Dishwasher: water inlet issue

Professional Repair Guide

What is this symptom?

If your Bosch dishwasher isn't filling with water or is filling slowly during a wash cycle, it could be due to several issues. Common causes include a faulty water inlet valve or blocked water supply lines. Addressing these problems promptly ensures efficient cleaning performance.

Urgency: Medium

Possible Causes

Faulty or clogged water inlet valve

How to Identify: Dishwasher runs but no water enters; humming noise when valve should open; test valve for electrical continuity and water flow; visible debris at valve inlet screen.

Part: Water inlet valve (solenoid valve)

Closed or blocked water supply and supply hose issues

How to Identify: Water supply valve to dishwasher not fully open; hose kinked, bent or blocked causing restricted water flow; verify water pressure at tap.

Part: External water supply valve and supply hose

Malfunctioning float switch or float assembly

How to Identify: Float stuck in raised position preventing water fill; test switch for continuity; free float moves smoothly up/down.

Part: Float switch / float assembly

Preventive Maintenance
