Quick Answer
If your KitchenAid Dishwasher Clean Light Blinking issue occurs during a wash cycle, the appliance has detected a fault and may have paused operation. Common causes include a failed wash cycle, heating element issues, dirty filters, control board glitches, or problems with water temperature. In many cases, resetting the dishwasher and running the built-in diagnostic cycle can clear the blinking clean light.
What Does a KitchenAid Dishwasher Clean Light Blinking Error Mean?
A KitchenAid Dishwasher Clean Light Blinking warning can be caused by several different issues. The control board uses the clean light to alert you when it detects a problem during the wash cycle.
Common symptoms include:
- Clean light flashing repeatedly
- Dishwasher not starting
- Cycle stopping unexpectedly
- Dishes not drying properly
- Water remaining in the tub
Fortunately, many blinking clean light issues can be resolved without replacing major components.
Common Causes of a KitchenAid Dishwasher Clean Light Blinking
Several issues can trigger the blinking clean light:
- Temporary control board malfunction
- Failed heating element
- Water not reaching proper temperature
- Dirty dishwasher filter
- Blocked spray arms
- Faulty thermostat
- Electronic control board problems
Identifying the root cause helps prevent unnecessary repairs.
Step 1: Reset the Dishwasher
A simple reset often clears temporary electronic faults.
To reset the dishwasher:
- Turn off the dishwasher.
- Disconnect power at the breaker or unplug the unit.
- Wait 5 minutes.
- Restore power.
- Start a normal wash cycle.
If the blinking light disappears, the issue was likely a temporary control board glitch.

Step 2: Run the Diagnostic Cycle
Many KitchenAid dishwashers include a built-in diagnostic mode.
The exact button sequence varies by model, but most units allow access through a combination of keypad presses.
Running diagnostics can:
- Clear stored fault codes
- Test dishwasher components
- Identify specific failures
Consult your owner’s manual for the correct diagnostic sequence.
Step 3: Clean the Dishwasher Filter
A clogged filter can restrict water flow and cause cycle errors.
To clean the filter:
- Remove the lower dish rack.
- Locate the filter assembly at the bottom of the tub.
- Twist and remove the filter.
- Rinse thoroughly under warm water.
- Reinstall securely.
A clean filter improves performance and helps prevent future error conditions.
Step 4: Inspect the Heating Element
The heating element helps heat the wash water and dry dishes.
Inspect for:
- Visible damage
- Burn marks
- Corrosion
- Broken sections
A failed heating element is one of the most common causes of a blinking clean light because the dishwasher cannot achieve the required water temperature.
Step 5: Check the Water Temperature
KitchenAid dishwashers typically require incoming water temperatures near 120°F.
To verify:
- Run hot water at the kitchen sink.
- Measure the temperature using a thermometer.
- Adjust the water heater if necessary.
Water that is too cool can cause wash cycle failures and trigger warning lights.

Step 6: Inspect the Spray Arms
Blocked spray arms can reduce cleaning performance and interfere with cycle completion.
Check for:
- Food debris
- Mineral buildup
- Clogged spray holes
- Physical damage
Remove debris and rinse thoroughly before reinstalling.
Step 7: Examine the Control Board
If the blinking clean light remains after completing the previous steps, the electronic control board may be malfunctioning.
Inspect for:
- Burn marks
- Loose wiring
- Damaged connectors
- Signs of moisture intrusion
Control board issues typically require replacement if visible damage is present.
When to Call a Professional
Consider contacting an appliance technician if:
- The clean light continues blinking after diagnostics
- The heating element tests faulty
- The control board appears damaged
- Electrical testing is required
A professional can safely diagnose advanced electrical faults and component failures.
