Could a failing Door Latch Assembly cause the BOSCH ASCENTA SERIES DISHWASHER to have symptom: Flashing?

The door latch assembly contains the microswitch responsible for signaling the control module that the unit is sealed. If the mechanical catch fails to hold the door tight against the gasket, or if the switch contacts are oxidized, the circuit will break during the high-vibration wash phase. This triggers the 'Cycle Interrupted' logic, resulting in the flashing status light.

Could a failing Control Power Cable Junction Box Kit cause the BOSCH ASCENTA SERIES DISHWASHER to have symptom: Flashing?

Bosch Ascenta models have a known failure point at the power connection junction box where thermal cycling can cause loose connections. Intermittent power delivery to the control board can cause the logic to reset or hang in a 'paused' state, manifesting as flashing LEDs upon partial power recovery.

Could a failing Main Control Board cause the BOSCH ASCENTA SERIES DISHWASHER to have symptom: Flashing?

If the door latch and power supply are stable, the internal relays or logic processor on the control board may be failing to register the 'Start' command or 'Door Closed' signal. This represents a breakdown in the signal processing layer of the machine's architecture.
