Bosch Dishwasher: not starting cycle
What is this symptom?
If your Bosch dishwasher isn't starting the wash cycle, you may notice no sounds or water flow despite the control panel lighting up. This issue can stem from a door that isn't fully closed, a malfunctioning door latch, or an activated control lock. Understanding these potential causes can help you troubleshoot effectively and get your dishwasher running again.
Important Tips for Bosch Models
- Bosch models often have multiple safety interlocks; control panel may not indicate which interlock is blocking start.
Possible Causes
Door not fully closed or door latch/switch failure
How to Identify: Dishwasher door appears closed but cycle doesn’t start; pressing harder or inspecting latch shows misalignment or lack of click.
Part: Door latch / door switch
Control lock/child lock activated
How to Identify: Control panel indicators show lock icon or buttons unresponsive to cycle start but respond to lock toggle.
Part: Control panel lock function
DIY Solutions

Deactivate control lock/child lock
