Bosch Dishwasher: control panel lights on, machine activating with door open
What is this symptom?
Experiencing issues with your Bosch dishwasher? If the control panel lights are illuminated and the machine activates even with the door open, it may indicate a faulty door latch or switch. This problem can lead to improper door status detection, causing the machine to operate when it shouldn't. Understanding these causes can help you resolve the issue effectively.
Important Tips for Bosch Models
- Bosch service documentation and community cases highlight that door latch issues and misread door status are common causes of unusual operation behavior including lights on without proper cycle start.
Possible Causes
Faulty or misaligned door latch/door switch
How to Identify: Dishwasher behaves as if the door is closed when open; lack of proper click or engagement when closing door; symptoms consistent with misread door state. Dishwashers should not operate with open door due to safety switches.
Part: Door latch assembly / door switch
Flood/flood switch (false trip due to water in base)
How to Identify: Dishwasher activates drain pump unexpectedly; standing water in base pan detected; behavior unaffected by door position.
Part: Flood switch / base pan float assembly
DIY Solutions
Inspect and secure the door latch and switch
- Power off the dishwasher and open the door.
- Visually inspect the door latch mechanism for physical damage or misalignment.
- Close the door slowly, listening for a clear 'click' indicating switch engagement.
- If visible debris is present around latch area, gently clean with a dry cloth.
- Test operation after ensuring latch engages correctly.
Power reset to clear control board glitches
- Turn off the dishwasher at the power source (circuit breaker or unplug).
- Wait 5–10 minutes to allow electronics to reset.
- Restore power and observe if lights and behavior normalize.
