Bosch Dishwasher: not starting
What is this symptom?
If your Bosch dishwasher is not starting, you may notice it is completely silent or has lights on without any response. This issue can often be linked to problems with the door latch, control lock, or power supply. Identifying the exact cause is crucial for getting your appliance back to work efficiently.
Possible Causes
Door latch or door switch safety interlock not engaging
How to Identify: Dishwasher will not start even though power is present and control panel appears functional; door doesn’t click firmly or repeatedly fails to latch.
Part: Door latch assembly / door switch
Control lock (child lock) activated
How to Identify: Control panel shows padlock or "CL" icon; buttons appear unresponsive until lock is deactivated.
Part: Control panel lock feature
Power supply issue — breaker, outlet, connection
How to Identify: No lights or sounds; external outlet not supplying power; tripped breaker; unit unplugged or loose plug.
Part: Electrical power circuit (breaker, plug, outlet)
Delayed start setting engaged
How to Identify: Display shows countdown or delay indicator; dishwasher starts after delay ends or when delay is cancelled.
Part: Control panel and timer settings
