If your Kenmore dishwasher clean light flashing 4 times blue and green, it usually means the machine has detected a fault and locked itself. The dishwasher won’t start until the issue is fixed or reset.
Here’s a clear, real-user guide to help you diagnose and fix it.
Quick Answer
A clean light flashing 4 times on a Kenmore dishwasher typically indicates a wash motor circuit error. Try a reset first. If it continues, check the motor, wiring, or fuses.
Step-by-step fix for Kenmore clean light flashing 4 times
Step 1: Perform a basic reset
Start with the easiest fix.
- Unplug the dishwasher or switch off the breaker
- Wait 1 full minute
- Restore power
👉 This clears temporary errors in the control board.
Step 2: Try keypad reset sequence
Some Kenmore models respond to a manual reset.
- Press: Heated Dry → Normal → Heated Dry → Normal
- Do this quickly
The dishwasher should enter a short test cycle.
Step 3: Understand the error code pattern
Kenmore models without screens use flashing lights as codes.
- Flashing 4 times repeatedly = specific fault
- Blue + green together = system alert
In your case, this points to a wash motor circuit problem.
Step 4: Inspect the wash motor
The wash motor is responsible for circulating water.
Check for:
- Loose wiring connections
- Burnt or damaged wires
- Signs of overheating
If the motor isn’t running, the dishwasher cannot wash.
Step 5: Check wiring and connections
Remove the lower front panel (toe kick).
- Look for disconnected plugs
- Inspect harness connections
- Ensure nothing is loose or corroded
Step 6: Test with a multimeter (advanced)
If you’re comfortable:
- Locate the tech sheet (usually behind the bottom panel)
- Test motor windings
- Check continuity of circuits
👉 If readings are off, the motor or fuse may be faulty.
Step 7: Check thermal fuse
A blown thermal fuse can stop the dishwasher.
- Located near the control board
- Test for continuity
- Replace if faulty
Extra tips and best practices
- Always cut power before opening panels
- Take photos before disconnecting wires
- Clean filters regularly to reduce strain on the motor
- Avoid overloading the dishwasher
Common mistakes to avoid
- Ignoring the reset step (it solves many cases)
- Replacing parts before checking wiring
- Misreading the flashing pattern
- Skipping safety precautions when testing
