Common Causes
Experiencing the Frigidaire dishwasher 3 lights blinking can be frustrating. This issue usually signals a problem that needs attention. Understanding the common causes can help you troubleshoot effectively.
Control Board Issues
The control board is the brain of your dishwasher. It manages all functions and settings. If the control board has a fault, the dishwasher might malfunction. This can lead to the 3 lights blinking issue. Here are some signs of control board problems:
- Dishwasher does not start.
- Cycles do not complete.
- Buttons do not respond.
To fix this, you may need to reset the control board. Unplug the dishwasher for a few minutes, then plug it back in. If the problem persists, consider replacing the control board.

The door latch ensures the dishwasher door is securely closed. If the latch is faulty, the dishwasher won’t start. This can also cause the lights to blink. Common door latch issues include:
- Door does not lock properly.
- Dishwasher stops mid-cycle.
- Lights blink when the door is closed.
Inspect the door latch for any visible damage. Ensure it clicks when closing the door. If the latch is broken, you may need to replace it. This can usually be done with a screwdriver and a new latch kit.
By addressing these common causes, you can often resolve the Frigidaire dishwasher 3 lights blinking issue quickly. Always refer to your user manual for specific instructions and safety guidelines.

Inspecting The Door Latch
When your Frigidaire dishwasher shows 3 blinking lights, it may indicate a door latch issue. Inspecting the door latch can help you identify the problem. Follow these steps to perform a thorough inspection.

Sensor Issues
When your Frigidaire dishwasher’s three lights blink, sensor issues might be to blame. Sensors play a key role in the dishwasher’s performance. Problems with these can lead to malfunction. Two critical sensors are the water level sensor and the temperature sensor. Let’s explore these in detail.
Water Level Sensor
The water level sensor monitors the amount of water in the dishwasher. This sensor ensures the machine fills to the right level. If this sensor fails, it can trigger the three lights to blink.
A faulty water level sensor may cause underfilling or overfilling. Both can affect cleaning performance. Check for blockages or debris around the sensor. Cleaning it might solve the issue. If the problem persists, consider replacing the sensor.
Temperature Sensor
The temperature sensor ensures water heats to the correct temperature. Hot water is vital for proper cleaning. If this sensor malfunctions, it might cause the three lights to blink.
A broken temperature sensor can result in water that is too hot or too cold. This can hinder cleaning efficiency and damage dishes. Inspect the sensor for any visible damage. If necessary, replace it to restore normal function.
