If you’ve ever found yourself staring at your GE dishwasher with confusion as it flashes its lights at you, you’re not alone. Dishwashers are sophisticated appliances, and when they start flashing, it’s usually an indicator of an issue that needs attention. In this article, we’ll dive into the common reasons behind the flashing lights on your GE dishwasher and provide you with a step-by-step troubleshooting guide to resolve these issues.

Modern dishwashers like the GE models are equipped with advanced technology that includes LED lights to indicate various stages of operation and potential problems. When these lights start to flash unexpectedly, it can be perplexing. Let’s explore the possible reasons and how to address them.

Understanding the Flashing Lights

Flashing lights on your GE dishwasher are its way of communicating a problem. Each pattern of flashing corresponds to a specific issue, which can range from simple solutions to more complex ones. Understanding the code is the first step in deciphering what’s wrong.

Possible Reasons for Flashing Lights

Power Issues

A common cause of flashing lights is a power disruption. Check if the dishwasher is properly plugged in and if there’s an issue with the circuit breaker or outlet.

Door Lock Problems

Improperly latched doors can trigger flashing lights. Ensure that the door is securely closed and the latch is functioning.

Water Supply Problems

Insufficient water supply or a blocked water inlet valve can lead to flashing lights. Examine the water supply and valve for any issues.

Drainage Obstructions

Flashing lights might indicate clogged drain pathways. Clear out any debris or blockages that might be affecting the drainage system.

Component Malfunctions

Malfunctioning components such as sensors, heating elements, or control boards can trigger flashing lights. A thorough inspection is necessary to identify the faulty part.

Troubleshooting Steps

Checking the Power Source

Start by verifying the power source. Ensure the dishwasher is correctly connected to a power outlet and that there are no tripped circuit breakers.

Ensuring Proper Door Closure

If the door isn’t closing properly, the dishwasher won’t start. Make sure the door is fully closed and the latch is engaged.

Verifying Water Supply

Inspect the water supply line for kinks or blockages. Ensure the water inlet valve is clean and functioning.

Inspecting Drainage Pathways

Check for debris in the drain filter and the drain hose. A clogged drainage system can trigger flashing lights.

Examining Components for Damage

If none of the above steps resolve the issue, it’s time to inspect the components. Look for damaged or malfunctioning parts and replace them as needed.

Performing a Hard Reset

If troubleshooting doesn’t work, performing a hard reset can sometimes clear electronic glitches. Consult your user manual for instructions on how to reset your specific model.

Seeking Professional Help

If the problem persists, it’s best to seek professional assistance. Certified technicians have the expertise to diagnose and repair complex issues.

Maintenance Tips to Prevent Future Issues

Regular Cleaning

Keep your dishwasher clean by running regular cleaning cycles. Remove debris and food particles from filters and spray arms.

Loading Dishes Correctly

Improper loading can lead to drainage issues. Load dishes according to the manufacturer’s guidelines to ensure proper water circulation.

Using Quality Detergent

Using the right detergent prevents buildup that can clog components. Opt for a detergent that’s recommended for your dishwasher.
