What Causes Dishwasher Lights Flashing And Will Not Start?
Several reasons may lead to dishwasher lights flashing continuously. These reasons eventually prompt the device not to start in most cases. Some of the most commons reasons are stated below:
1. Faulty Door Latch
The door latch having issues might be one of the causes of the lights beeping. Mainly, the lights in the dishwasher start to blink whenever the door is opened. Usually, the light stops flashing when the door is closed.
But if it’s still blinking after closure, there are issues with the door latch. The reason can be either a broken door latch or the sensor giving faulty signals.
2. Door Not Closing
When the dishwasher door isn’t closed correctly, it will lead to lights beeping and flashing. The door closure is when you hear the snapping sound correctly.
There is no indication of the door closing without a proper snapping sound. That said, based on the dishwasher model, the closure mechanism might differ.
3. Defective Component
Some dishwasher models start flashing lights when there is a faulty component existing. It can be a situation where the thermistor has a short circuit or even issues with the touchpad. The best solution would be to figure out the exact defective component.
The problem might seem not to be that serious, but prolonging it will cause serious implications for the device. When some of the lights in the dishwasher are flashing with beeping, most commonly, there can be two faults.
One is a faulty door latch, and another is a defective control panel. That said, if you have some DIY tools, it’s possible to fix this problem yourself. The steps for fixing the problem are mentioned below:
Step-1: Install A New Door Latch
The first step would be to install a new door latch. The lights often start blinking and beeping due to a faulty latch. To install a new latch, follow the directives as mentioned:
- Open the dishwasher door and head towards the upper compartment
- Take a drill and loosen the screw holding the door latch
- Take out the existing latch and put a new one in place
- Tighten the screws to fit the new latch in its place
Step-2: Check The Lights
Now, check whether the yellow and start lights are still beeping. If the problem persists, the issue originated from the control panel. To get a solution, move on to the next step.
Step-3: Remove The Bottom Cover
This step will start with turning off the breaker. After that, you must remove the bottom cover by unscrewing the bolts with the drill. Then, take out the insulation to make the control board exposed.
Step-4: Remove The Control Board
Start the removal process of the control board with a drill by unscrewing the two bolts that are holding it. After that, disconnect every plugin and remove the screws. Lastly, remove all the harnesses and clamps to remove the control board.
Step-5: Install The New Control Board
Before installing the new board, disconnect the old one from the metal shield completely. You’ll see that a few screws and some clamps are attaching the board to the shield. Detach the panel by taking those out and then placing the new one.
Tighten the screw and clamps to give a new control board firm protection through the shield. Then, install the board right into its compartment and reinstall the bottom cover.
Step-6: Turn On The Breaker
Turn the breaker on and see whether the yellow lights continue blinking. If it stops blinking, the problem is solved. Or else, you will need a mechanic consultation to solve the problem.
Fixing the dishwasher not starting and light flashing is possible when replacing the control board or the door latch. But if none of these works, then there can be problems that will give you a headache.
The defective components inside can be one of the roots of this issue, and it is better to replace them immediately. Taking time to replace them might prove to be hazardous as it can also affect other components.
Other than this, not replacing or repairing the faulty part may even affect the total cycle of the dishwasher.

However, Irrespective of the model, the door latch should be tested and checked whether it is the leading cause. As for most models, it is one of the common issues. Apart from this, you should not address the problem with a delay as it can have negative implications.
Moreover, dishwasher lights flashing and will not start may not seem severe until you figure out its root in the control board. Therefore, inspect the issue properly and try out the possible solutions before expert consultation.
