Bosch Dishwasher: not powering on
What is this symptom?
If your Bosch dishwasher is not powering on, it may show no lights or response when you press the Start button. This common issue can stem from a lack of power, a faulty door latch, or a locked control panel. Understanding the potential causes can help you troubleshoot effectively and restore functionality to your appliance.
Important Tips for Bosch Models
- Bosch dishwashers will not start or power on unless the door is fully closed and latched due to safety interlock.
- Many Bosch models include a child lock feature that can prevent starting if active.
