What Does The Blinking Clean Light Mean?
When your Kenmore dishwasher’s clean light blinks, it’s not just a random event. The dishwasher is telling you something is wrong. Usually, this light signals an error in the cleaning cycle. The dishwasher finished its job but found a problem during washing or rinsing.
Common causes include:
- Heating problems: The water didn’t get hot enough.
- Drainage issues: The dishwasher couldn’t drain water properly.
- Sensor errors: Sensors inside the machine detected something unusual.
- Control board glitches: Sometimes, the computer inside the dishwasher gets confused.
Most Kenmore dishwashers use the clean light as a trouble signal. The light may blink in a specific pattern, for example, seven times. This pattern helps you and technicians understand the exact problem.
Why Does The Clean Light Blink? Common Causes Explained
Understanding the root cause helps you fix the issue faster. Here are the most common reasons the clean light blinks:
1. Water Heating Problems
Dishwashers need hot water—usually at least 120°F (49°C)—to clean dishes well. Kenmore models have a heater or heating element. If the water doesn’t reach the right temperature during the final rinse, the dishwasher stops and the clean light blinks.
- Faulty heating element: It may be burned out or broken.
- Bad thermostat: The dishwasher can’t sense water temperature correctly.
- Wiring issues: Loose or damaged wires can cause heating failures.
2. Draining Issues
After washing, your dishwasher must pump out dirty water. If it can’t drain properly, the clean light may blink.
- Clogged drain hose: Food or debris blocks the hose.
- Blocked air gap: The small device near your faucet gets clogged.
- Faulty drain pump: The pump may be jammed or broken.
3. Dirty Or Blocked Filters
Kenmore dishwashers have filters to catch food and debris. If these are dirty, water can’t flow well, causing errors.
- Overlooked filter cleaning: Many people forget to check and clean filters.
- Grease buildup: Grease and soap scum can clog filters over time.
4. Door Latch Or Door Switch Problems
If the door isn’t fully closed or the latch is faulty, the dishwasher may stop mid-cycle and show a blinking light.
- Loose latch: The door feels closed but isn’t fully engaged.
- Broken switch: The dishwasher thinks the door is open.
5. Control Board Glitches
Like a computer, your dishwasher has a control board. Power surges or software errors may confuse it, leading to a blinking light even if nothing is wrong.
- Static electricity: Rare, but it can cause temporary errors.
- Improper shutdown: Unplugging the dishwasher mid-cycle can cause glitches.
6. Sensor Or Float Problems
Modern dishwashers use sensors to check water levels and temperatures. If a sensor is dirty or broken, the dishwasher gets confused.
- Stuck float switch: The float may be jammed by debris.
- Bad sensor: Sensors can wear out after years of use.
7. User Errors
Sometimes, a simple mistake—like opening the door too soon or pressing the wrong button—can trigger the blinking light.
Non-obvious insight: In many Kenmore models, running the hot water at your kitchen sink for a few seconds before starting the dishwasher helps prevent heating errors.

Decoding The Blinking Pattern
Not all blinking clean lights mean the same thing. Kenmore dishwashers often use 7 blinks as a code for a heating problem, but patterns can vary by model.
Here is a sample of what different blinking patterns might mean:
| Blink Pattern | Possible Meaning | What to Check |
|---|---|---|
| 7 blinks | Heating problem | Heating element, thermostat, wiring |
| 2-6 blinks | Control or sensor error | Control board, sensors, float switch |
| Continuous blinking | Door issue or system error | Door latch, switches, control board |
Pro tip: Check your dishwasher’s manual or search your model number online for the exact meaning of the blinking pattern.
Step-by-step Troubleshooting: Fixing The Blinking Clean Light
Solving the problem is easier if you follow a clear process. Here’s how to troubleshoot a Kenmore dishwasher clean light blinking issue:
Step 1: Reset The Dishwasher
Sometimes, the problem is just a small glitch. Try a simple reset first.
- Turn off power: Unplug the dishwasher or turn off the circuit breaker for 5 minutes.
- Plug it back in: Restore power and close the door.
- Start a short cycle: Run a rinse-only cycle to see if the light returns.
If the light is gone, the issue was a minor glitch.
Step 2: Check The Door Latch And Switch
The dishwasher won’t run if it thinks the door is open.
- Open and close the door firmly.
- Listen for a “click” when closing.
- Inspect the latch and the strike plate for damage.
- If the latch feels loose or the switch doesn’t engage, you may need a replacement.
Step 3: Inspect The Heating Element
The heating element is at the bottom of the dishwasher.
- Wait for the dishwasher to cool.
- Remove the lower rack.
- Look for visible damage, burns, or breaks.
- Use a multimeter to check for continuity (should show resistance; if not, it’s broken).
Data point: In Kenmore models, heating element failures are a top cause of blinking clean lights, especially after 5-7 years of use.
Step 4: Clean The Filters And Drain
Blocked filters and drains are very common.
- Remove the bottom rack.
- Twist out the filter (usually at the center or back).
- Rinse the filter under hot water, scrub off debris with a brush.
- Wipe out the filter housing area.
- Check the drain at the back for food or glass pieces.
- Inspect the drain hose under the sink for kinks or clogs.
Step 5: Examine The Drain Pump And Air Gap
The drain pump is under the dishwasher. The air gap is a small metal cylinder near your sink faucet.
- Remove the air gap cover and clean out any debris.
- Listen for a humming sound from the drain pump during the drain cycle. No sound means the pump may be stuck.
- Check for leaks or water around the pump.
Step 6: Test The Thermostat
The thermostat tells the dishwasher when the water is hot enough.
- Locate the thermostat (usually near the heating element).
- Use a multimeter to test for continuity.
- Replace if faulty.
Step 7: Inspect Sensors And Float Switch
The float switch sits in a small well in the dishwasher floor.
- Lift the float gently. It should move up and down.
- Clean around it to remove any stuck debris.
- Listen for a “click” as you move it up and down (shows switch is working).
Step 8: Review The Control Board
If everything else is fine, the problem may be with the main control board.
- Look for burned spots or damaged wires inside the control panel.
- Reset the dishwasher as described above.
- If the problem continues, you may need a professional to check or replace the board.
Non-obvious insight: Hard water buildup can cause hidden blockages in the heating element, making it seem like a heating failure when it’s just mineral deposits.
How To Run A Diagnostic Test
Many Kenmore dishwashers have a hidden diagnostic mode. This mode can help you find the exact problem.
Here’s a common way to enter diagnostic mode (check your manual for details):
- Press the following buttons in order: Heated Dry → Normal → Heated Dry → Normal.
- The lights on the panel will all light up.
- The dishwasher runs a self-test. Listen and watch for error codes or blinking patterns.
- Write down any error codes for reference.
Diagnostic tests are a powerful tool. They can save you time by pointing directly to the faulty part.
When To Call A Technician
You can solve many clean light blinking issues yourself, but sometimes, you need an expert.
Call a professional if:
- You smell burning or see smoke.
- The dishwasher trips your home’s circuit breaker.
- You’ve checked all common problems and the light still blinks.
- The dishwasher is under warranty (don’t open it yourself).
Most repairs cost between $100 and $250 for common problems like heating elements or drain pumps. Control board replacement may cost $200–$400.
Preventing Future Clean Light Blinking
Once you fix your Kenmore dishwasher, take steps to prevent the problem from coming back. Regular maintenance is key.
Simple Maintenance Tips
- Clean filters monthly: Take out and rinse under hot water.
- Run hot water at the sink: Before starting a cycle, run hot water until it’s hot to the touch.
- Use dishwasher cleaner: Once a month, run an empty cycle with a dishwasher cleaner to remove grease and mineral deposits.
- Check the drain hose: Make sure it’s not kinked or clogged.
- Inspect the door latch: Wipe and check for smooth operation.
- Use the right detergent: Too much soap can cause buildup and blockages.
Water Quality And Detergent Choices
Hard water can cause more buildup. If you notice white spots on dishes or inside the dishwasher, consider using a water softener or a detergent made for hard water.
Tip: Use the manufacturer’s recommended detergent and rinse aid for best results.
Regular Service
If your dishwasher is more than 5 years old, consider a professional checkup every 2 years. This can catch small problems before they become big ones.

Real-life Example: How A Family Fixed Their Blinking Clean Light
Let’s look at a real-world story. The Smith family in Ohio noticed their Kenmore 665 dishwasher started blinking the clean light after every cycle. At first, they tried resetting the dishwasher, but the problem returned. They read the manual, which said 7 blinks meant a heating problem.
They checked the heating element and found white buildup on it. After cleaning the element with vinegar and running a dishwasher cleaner, the problem stopped. They also started running hot water before each cycle. Their dishwasher ran for three more years without issues.
Lesson: Sometimes, simple cleaning and hot water can solve what looks like a complex problem.
Data: How Common Is The Clean Light Blinking Problem?
Based on customer reports and repair data:
- 30–40% of Kenmore dishwasher owners report seeing the clean light blink at least once.
- Of these, about 60% solve the problem with cleaning or resetting.
- 25% need a new heating element or sensor.
- Only 15% require professional repairs.
This means most owners can solve the problem themselves with a little guidance.
Mistakes To Avoid When Fixing The Blinking Clean Light
People often make these common mistakes when trying to fix a Kenmore dishwasher:
- Ignoring the filter: Many skip filter cleaning, but it’s a quick fix.
- Guessing the part: Buying a new part without testing can waste money.
- Skipping the reset: Always try a reset before opening the machine.
- Forgetting to check the manual: Every model is a little different. Always check your model’s guide.
- Not turning off power: Always unplug or turn off the breaker before opening up the dishwasher.
When It’s Time To Replace, Not Repair
Dishwashers last about 8–12 years. If your Kenmore is more than 10 years old and repair costs are high, consider a new machine.
Here’s a quick comparison:
| Option | Cost | Expected Lifespan | Pros | Cons |
|---|---|---|---|---|
| Repair old dishwasher | $150–$350 | 1–3 years | Cheaper now, less waste | More problems may follow |
| Buy new dishwasher | $500–$900 | 10+ years | More efficient, quieter, better features | Higher upfront cost |
Tip: If repair costs are over half the price of a new dishwasher, replacement is often the smarter choice.
