What does the 7 times blinking clean light mean on the KitchenAid dishwasher?

The 7 times blinking clean light on a KitchenAid dishwasher indicates a heating issue. This error occurs when the control board can’t detect the required temperature rise in the water. It signifies a problem with the dishwasher’s heating element or control board, preventing the water from reaching the necessary temperature for proper cleaning.

Why is my KitchenAid dishwasher clean light blinking 7 times?

The clean light on your KitchenAid dishwasher will blink 7 times to indicate a fault in the heating circuit. This occurs when the wires powering the heating element become disconnected, preventing the dishwasher from properly heating the water to wash and dry dishes.

Some uncommon possible causes include a faulty heating element, a defective thermostat that fails to regulate the temp, a damaged control board, a bad wash pump motor, insufficient power supply, a faulty door lock, a clogged filter, and a technical software bug.

When you see this 7-blink pattern, it means your dishwasher has detected an internal issue that is preventing the appliance from cleaning your dishes. The blinking is an error code designed to notify you about the heating-related issue so that you can identify the specific problem and fix it with ease. 

How do you fix a clean light blinking 7 times on a KitchenAid dishwasher?

First, ensure the dishwasher is receiving power by turning on the breaker. If the issue continues, follow the troubleshooting steps provided below.

Check the heating circuit.

A damaged heating circuit is one of the most common causes of the 7-blink error. Inside the dishwasher, the wires connect the heating element to the power supply, helping it to heat up the water during wash cycles.

Wires of the heating circuit of the dishwasher.

However, if these wires become loose, corroded, or disconnected, the heating element will not receive enough voltage to operate. As a result, the clean light flashes 7 times to indicate the heating problem.

To troubleshoot this, you’ll need to inspect the heating component wires connected to the dishwasher’s internal wiring and power supply. Check the circuit for any loose wire connections and tighten it securely.

Use a multimeter to check for continuity in the heating circuit wires. If the meter doesn’t show any readings, replace the wire harness.

To do so, you can call a professional, as he can do it more efficiently. You can also contact KitchenAid customer support for further assistance.

After that, start the dishwasher to check if the problem is resolved. If not, try the next method.

Check for a malfunctioning door lock.

A faulty door lock can also trigger the clean light to blink 7 times. You should latch the dishwasher door within three seconds of starting the wash cycle. However, if the lock is damaged or the dishwasher is overloaded with dishes, the door will be unable to close within 3 seconds.

The dishwasher will believe that there is an internal issue preventing its operation. As a result, it will flash the light seven times. 

To fix this, begin by ensuring no dishes are preventing the door from closing. Remove any oversized pans or plates. Inspect the door lock for any broken or loose components. You may need to replace the locking tabs or the catch. 

Fix the heater

Heater of the dishwasher.

The heating component is another potential reason for the 7-blink error code. The heater heats the air inside the dishwasher up to 170°F during the dry cycle. However, if the heating element has burned out or broken, it will be unable to generate enough heat.

No heat means the dishes will remain wet, resulting in the flashing clean lights on the control panel.

To test the heater, use a multimeter to check for the continuity in it. If it shows no continuity, replace the heater with a new functioning one.

Inspect the thermostat

If your clean light is still blinking seven times you must check the thermostat once.

The thermostat controls the heating element to maintain the proper water temperature during wash and dry cycles. However, if the thermostat is defective, it provides incorrect information about the temperature.

As a result, the machine will start to overheat or underheat. Overheating can damage dishes while underheating prevents the removal of dirt from the dishes. 

To fix this issue, use a thermometer to check the water temperature inside the dishwasher. If the reading differs from the one showing on display, it means the thermostat is defective and you will need to replace it. 

Buy a thermostat according to your dishwasher model and watch the video that I have provided below to learn the best way to replace it.

Clear the software glitches.

Software glitches on the dishwasher can also cause the 7-blink error. Other than the dirt and debris, these “technical bugs” can disrupt normal operations. 

However, rebooting the electronic control board often clears out these glitches. To do so:

  • First, unplug the power cord from the outlet.
  • Then, wait for 5 to 10 minutes.
  • Finally, reconnect the plug to complete the hard reset.

If the issue still continues, enter a special diagnostic mode on the KitchenAid dishwasher by pressing a sequence of buttons per the written in the user manual.

A defective wash motor

The clean light blinking errors can also be caused by a malfunctioning wash motor. The wash motor powers the circulation pump to spray water through the dishwasher spray arms and drain out dirty water. However, if the motor becomes defective, it will be unable to do these functions.

A defective wash pump motor of the dishwasher.

When the water will not spray and drain, the dishwasher will be unable to clean the dishes properly. As a result, you will see a seven times blinking light on the panel. First, ensure the spray arm is not clogged, before testing the motor.

To check the wash pump motor, you’ll need to schedule a service. Opening the dishwasher to access the motor is a little complex task. Call and ask a technician to repair your motor or replace it if necessary.

Check the Water Inlet valve

The inlet valve is in charge of controlling water flowing into the appliance. A faulty water inlet valve can hamper the proper dishwasher operation and cause the clean light to blink seven times.

You may notice the dishwasher not filling up enough, random filling even when powered off, or water leaking onto the floor due to that defect. 

To Troubleshoot the dishwasher’s inlet valve, inspect it carefully for cracks and leakage. Check the surroundings of the valve to clear the obstacles such as debris buildup.

Debris and build-up around the inlet valve.

If it is damaged badly, you should need to replace the water inlet valve by yourself or a professional technician. You can buy a new water inlet valve from an online or local store according to your model.

Inspect the sump filter for clogs.

The sump filter catches the food particles and debris from the water recirculating during wash cycles. However, over time, it can get blocked by dirt and debris.

A clogged filter will stop the water flow from spraying onto the dishes properly. Also, it will allow food particles to recirculate back onto the cleaned dishes. As a result, the dishwasher will illuminate the clean light 7 times on its panel.

Fortunately, cleaning a clogged sump filter is easy and can be done with some simple DIY steps. Follow the steps given below:

  • Disconnect the dishwasher’s power from it.
  • Now, open the dishwasher and locate the sump and filter at the bottom of the unit.
  • Identify the clogs and prepare warm soapy water.
  • Now use a brush and that solution to clear out the build-up and clog from the components.
  • Lastly, reassemble the freshly scrubbed components and restore the dishwasher’s power.

How can I reset my KitchenAid dishwasher to clear the flashing lights?

Resetting the power to your dishwasher can clear the software glitches triggering the clean LED to illuminate multiple times. A KitchenAid dishwasher does not have a specific reset button, so you’ll need to do it manually.

To reset your dishwasher, first, unplug it from the electrical outlet. Then, wait around 5-10 minutes. After that, plug it back in to restore the power. Doing this will restart the control board. Now, start your appliance to check if the issue is resolved.

If that basic reset doesn’t work, there is a more advanced reset method. It will require pressing a sequence of control buttons to activate a self-diagnostic mode. Refer to your user’s manual to learn the steps needed for that mode.

In most of the models, pressing some combination of buttons like “High-Temp Wash” and “Heated Dry” simultaneously can work. The dishwasher will run multiple tests to diagnose the issue.
