If your Frigidaire dishwasher has blinking lights, it could be a sign of a faulty water inlet valve. You can test the valve using a multimeter to check its electrical continuity and determine if it's functioning properly.
Common Causes Of Blinking Lights
If you have a Frigidaire dishwasher with blinking lights, it can be frustrating and worrisome. Understanding the common causes of blinking lights can help you troubleshoot the issue and potentially fix it yourself. In this section, we will explore some of the most common causes of blinking lights and how to address them.
Water Supply Issues
One of the common causes of blinking lights in a Frigidaire dishwasher is a water supply issue. If your dishwasher won't start but has power, it's essential to check your water supply. Here are a few quick inspections you can do:
Make sure the water supply valve is turned on to allow water flow to the dishwasher. If the valve is stuck, it may need to be replaced.
Verify that the water inlet hose is not kinked, as this can restrict water flow to the dishwasher.
Check the water pressure in your home. If the water pressure is too low, it can prevent the dishwasher from filling adequately.
In practice, a partially closed water supply valve is one of the most overlooked causes. Even a slight turn can reduce flow enough to trigger a blinking light pattern, especially on newer models with electronic sensors. Running the kitchen faucet nearby can help you confirm you have adequate flow to the dishwasher connection.
Faulty Water Inlet Valve
Another common cause of blinking lights is a faulty water inlet valve. The water inlet valve is responsible for allowing water into the dishwasher during the wash cycle. If the valve malfunctions, it can cause blinking lights and prevent the dishwasher from operating correctly.
To test the water inlet valve, you can use a multimeter to check for electrical continuity in the valve's solenoids. If there is no continuity, it indicates a malfunctioning valve that needs to be replaced.
Replacing a faulty water inlet valve is a relatively simple task that can be done with basic tools. However, if you are uncomfortable with DIY repairs, it's best to consult a professional technician to ensure the valve is replaced correctly.
A common mistake is assuming the valve is bad when the problem may actually be a clogged inlet screen. Sediment or mineral deposits can block the screen, restricting water entry even when the valve itself has continuity. Pull the inlet hose and inspect the small mesh screen; clean it with a soft brush before replacing the valve. This step alone resolves many blinking-light issues without any part replacement.
By addressing these common causes of blinking lights, you can potentially resolve the issue with your Frigidaire dishwasher. However, if the problem persists or you are unsure about performing repairs yourself, it's always recommended to seek professional assistance.

Resetting The Dishwasher
If your Frigidaire dishwasher has blinking lights and won't start, it may indicate a water supply issue. Check if the water supply valve is turned on and not stuck. For a quick reset, turn off the dishwasher, unplug it from the power source, wait a few minutes, then plug it back in and turn it on again.
Power Cycling The Dishwasher
One of the easiest ways to reset a Frigidaire dishwasher is by power cycling it. Power cycling involves turning off the dishwasher and disconnecting it from the power source for a few minutes. This allows the dishwasher's internal components to reset and can often resolve any blinking light issues. Follow these steps to power cycle your Frigidaire dishwasher:
Turn off the dishwasher by pressing the power button or unplugging it from the wall.
Wait for at least five minutes to ensure that all internal components have fully reset.
Plug the dishwasher back into the power source or turn it back on using the power button.
Check if the blinking lights have stopped and the dishwasher is functioning properly.
Clearing Error Codes
If power cycling doesn't resolve the blinking lights issue on your Frigidaire dishwasher, you may need to try clearing error codes. Error codes indicate specific problems that the dishwasher has detected, and clearing them can often solve the issue.
Follow these steps to clear error codes on your Frigidaire dishwasher:
Turn off the dishwasher by pressing the power button or unplugging it from the wall.
Wait for a few seconds and then press and hold the "Start" or "Cancel" button.
While holding the button, plug the dishwasher back into the power source or turn it back on using the power button.
Continue holding the button until the dishwasher's lights flash or you hear a beep sound, indicating that the error codes have been cleared.
Release the button and check if the blinking lights have stopped and the dishwasher is functioning properly.
Some Frigidaire models store error codes in memory even after a reset. If the blinking lights return immediately, the underlying issue hasn't been corrected — don't rely solely on clearing the code. Instead, note the specific pattern (e.g., fast blinks vs. slow blinks) and cross-reference it with the error code list in your user manual to pinpoint the failing component.
If these troubleshooting steps don't resolve the blinking lights issue on your Frigidaire dishwasher, it's recommended to consult the dishwasher's user manual or contact Frigidaire customer support for further assistance.
Troubleshooting Steps
If your Frigidaire dishwasher's blinking lights are causing trouble, there are a few troubleshooting steps you can follow to resolve the issue. Start by checking the water supply valve and ensure it's turned on. If it's stuck, consider replacing it.
You can also try resetting the dishwasher by turning it off, unplugging it for a few minutes, and then plugging it back in.
Checking The Door
If your Frigidaire dishwasher is experiencing blinking lights, the first troubleshooting step is to check the door. Make sure that the dishwasher door is securely closed and latched properly. Sometimes, a loose or improperly closed door can trigger the blinking lights and prevent the dishwasher from starting.
If the door is closed properly but the lights continue to blink, it's important to inspect the door latch mechanism. Look for any signs of damage or wear on the latch and ensure that it is engaging properly with the door switch. Replace the latch if necessary to resolve the blinking lights issue.
Inspecting The Start Button
Another troubleshooting step is to inspect the start button on your Frigidaire dishwasher. Ensure that the button is not stuck or jammed, as this can prevent the dishwasher from starting and cause the lights to blink.
If the start button appears to be in good condition, try resetting it by pressing and holding it for a few seconds. This can sometimes reset the control panel and clear any errors or issues causing the blinking lights. If the problem persists, you may need to replace the start button.
Verifying Power Supply
In some cases, a blinking lights issue on your Frigidaire dishwasher may be due to a problem with the power supply. To verify this, follow these steps:
Check the power outlet: Ensure that the dishwasher is plugged into a functioning power outlet. Test the outlet with another device to confirm that it is providing power.
Reset the circuit breaker: If the dishwasher is connected to a circuit breaker, check if it has tripped. Reset the breaker by flipping it off and then on again.
Inspect the power cord: Examine the power cord for any signs of damage or wear. If you notice any issues, replace the power cord.
Test with another appliance: Plug another appliance into the same outlet to see if it works. If it doesn't, there may be an issue with the electrical system, and you should consult a professional electrician.
A frequently missed detail: some Frigidaire dishwashers have a small circuit breaker on the lower front panel (under the door). If this internal breaker has tripped, the dishwasher may show power but still blink lights. Press the reset button on that breaker using a pen or small screwdriver, then retry the cycle.
By following these troubleshooting steps and addressing the potential causes of blinking lights on your Frigidaire dishwasher, you can resolve the issue and get your dishwasher back up and running efficiently.

Understanding Blinking Light Patterns
Your Frigidaire dishwasher's blinking lights are not random — they follow a specific language. Knowing what each pattern means can save hours of guesswork.
Identifying Common Patterns
- One light blinking repeatedly – Typically indicates a water supply issue, such as a closed valve or kinked hose.
- Two lights alternating – Often points to a drain problem, like a clogged filter or blocked drain hose.
- All lights flash at once – Usually signals a control board fault or a power surge event.
- Light blinks every few seconds – Standby or delay start mode; this is normal and not a fault.
Refer to your model's error code table in the user manual for the exact sequence. For a comprehensive list, the Frigidaire official error code support page provides detailed explanations by model number.
Common Error Codes for Frigidaire Dishwashers
Some Frigidaire models display error codes through specific light combinations. Here are the most frequent ones:
- i10 / i20 / i30 – Water inlet or drain timeout errors. Likely causes: clogged filter, restricted hose, or faulty pump.
- i50 – Water heater failure. Test the heating element with a multimeter.
- i60 – Motor or wash pump failure. Listen for unusual noises during Diagnostic Mode.
- i70 – Overflow sensor activated. Check for leaks or a stuck float switch.
If you encounter a blinking light pattern that matches one of these codes, address the root cause rather than simply resetting the machine. A similar blinking issue can also appear on other kitchen appliances — for instance, a GE dishwasher with a blinking orange light often shares the same water-inlet diagnosis.
