Bosch dishwasher blinking red light

As my old father had just come visiting, my wife decided to be the gracious host and treat us to a delicious home-cooked dinner. 

You need to be there to perceive the aroma of her culinary prowess as it fills the air!

Later that night as we approached the sink to load our dirty dishes.

The dishwasher was working perfectly until it began to flash a bright red light.

This blinking just won’t stop and it began to affect the run of the appliance. I had no choice but to find a fix and then I proceeded to do some research.

I found out that your Bosch dishwasher usually blinks the red light if the door latch is left open or not properly locked.

However, there’s more! Continue reading this article to find out how we eventually got the issue fixed.

Why Is Your Bosch Dishwasher Blinking Red Light?

What I mentioned above is the main reason why most people’s dishwashers usually blink the red light.

Pressing the start button

#1. The Door Latch Is Open

When your dishwasher flashes a red light. It’s simply telling you that you forgot to close the door properly.

Most appliances won’t run a cycle if the door is not closed. Actually, this is for your own good as it’s important for safety purposes

Solution ?

I was able to solve the problem by just opening the door and I made sure it was properly closed back.

You should try this too if you’re experiencing this problem. 

However, if you’ve done this and the red light is still persistent – it could be that your door latch is broken due to a faulty sensor or damaged hinges.

#2. Reset The Dishwasher 

Now, if the door latch seems to be okay and you’ve done as i stated above but the light still blinks.

An alternative solution is to reset the dishwasher’s control panel.

Sometimes the control panel might be receiving or sending wrong signals to the door latch. 

It’s a good idea to reset it in order to return your dishwasher back to default settings.

To reset the dishwasher, just press and hold the “start” button for 5 seconds.

However, if you’re using an older Bosch dishwasher ,- you might have to press the “Power” button instead of the start button.

That should do! You can also hard reset it by flipping the circuit breaker for your dishwasher specifically.

#3. Check For Any Water Disconnections

Check For Any Water Disconnections

Some other unlikely causes which are also worth checking out is the water supply unit of your dishwasher.

This basically carries water into your dishwasher. You need to make sure that you’ve turned on the water supply to your dishwasher.

And also, check to see if there are blockages in the water inlet hoses. All of these might adversely affect the proper running of your dishwasher.

What Should I Do If Nothing Works?

If the red light still keeps flashing but your Bosch dishwasher is working perfectly with it. 

Then you really have nothing much to worry about. It will obviously go away on its own with time.

However, if the light is interfering with the proper functioning of your dishwasher and all above fixes don’t work.

It could be that the door latch and sensor is damaged. It will cost you a few bucks to replace it.

Sometimes, the control panel can also be faulty. 

I recommend that you reach out to Bosch or an expert appliance technician to help you fix it. But if you can also fix it yourself – no problem.
