What is this symptom?

This issue may arise from various factors, including the selected cycle, water inlet hose problems, or clogged filters. Understanding these causes can help you find the right solution to optimize your machine's performance.

Important Tips for Bosch Models

  • Bosch models use load sensors and program logic to adjust water; perceived high water usage may be normal under certain programs.

Possible Causes

Normal water usage based on model and cycle selection

Water inlet hose issues (kinks, low pressure) resulting in slow/insufficient fill

How to Identify: Slow filling or lower water level than expected; visible hose bends or pressure issues at tap.

Part: Water inlet hose / supply

Blocked or restricted water inlet filters

How to Identify: Reduced water flow into machine even when tap fully open; debris visible on inlet filter.
