Frequently Asked Questions about Why Is Bosch Dishwasher Red Light Blinking

Why does my dishwasher start button just blink?
The flashing Start/Resume light on certain models of a device indicates that the cycle or startup process has been interrupted. This can occur if the door is opened during the cycle or if there is a power outage. To fix this, simply close the door firmly within three seconds of pressing the Start/Resume button.

Why are the lights flashing and not starting my Bosch dishwasher?
If the lights on your dishwasher are flashing, it may be due to a micro switch issue in the door latch assembly. To check if this is the problem, use a multimeter to test the switch’s continuity. If the switch is faulty and doesn’t have continuity, you should replace either the switch or the entire latch assembly.

Why won’t my dishwasher start when I press start?
If your dishwasher isn’t functioning at all, there may be an issue with the power supply. First, check the circuit breaker and reset it if it has tripped. If the circuit breaker is not the issue, verify that the dishwasher is properly plugged into the wall outlet. This troubleshooting process can help resolve the problem.
