If your Bosch dishwasher isn’t starting, one common issue could be related to the water inlet. Inspecting this component is essential, as it ensures that the dishwasher receives the necessary water supply to function properly. Understanding how to check the water inlet can help you diagnose and resolve the problem effectively.

Inspect the drain hose for kinks or clogs.
Check the garbage disposal if connected to ensure it is clear.
Remove and clean the filter located at the bottom of the dishwasher.
