What is this symptom?

Urgency: Medium

Important Tips for Bosch Models

  • Bosch dishwasher diagnostics and error codes can be referenced via the official support hub or manual but specific ‘no start’ codes should be diagnosed by technician if not resolved by basic checks.
  • Some Bosch models show blinking lights to indicate internal faults; persistent blinking may indicate control or sensor issues.

Possible Causes

Tripped circuit breaker / no electrical power to dishwasher

How to Identify: Dishwasher display and controls are completely unresponsive; other appliances on the same circuit also lack power.

Part: Home electrical supply / breaker

Door latch not securely closed or faulty

How to Identify: Dishwasher will not start unless door fully latches; often clicking sound missing or indicator shows door open.

Part: Door latch mechanism / sensor

Control panel / electronic control board fault

How to Identify: Display is partially lit but buttons don’t respond; power cycling does not restore function.

Part: Control panel or PCB

Water inlet or supply issue (safety prevents start)

How to Identify: Dishwasher does not detect water supply; some models show error codes related to water supply.

Part: Water inlet valve
