A flashing clean light on a Kenmore dishwasher usually means the unit has detected a heating failure. This safety lock prevents the machine from running until the heater, thermostat, or control board is inspected. You can often reset this by pressing a specific button sequence on the console to clear the stored fault.
If you keep doing the reset and ignoring it, you'll eventually fry the heater relay on the control board and turn a $35 element job into a $120 board replacement. I've seen it happen. Usually when I show up for this one, it's the heating element and it's been flashing for two weeks while someone ran it anyway. Fix it now, not later.
OK so here's the deal. Most of the time when I see this, the heating element has just given up. It's a wear part, and Kenmore dishwashers put a lot of hard cycles on them. The reset trick works once, maybe twice, but if there's a real break in that heater circuit, the light's coming right back. Parts run $20-45 and it's honestly not a terrible Saturday afternoon repair.
Most Likely Causes
Based on aggregated repair data, here is the probability breakdown for this error code:
Heating Element Failure60%
Tripped or Failed High Limit Thermostat25%
Control Board Relay Failure10%
Loose or Corroded Wiring5%
Symptoms You May Notice
The clean light blinks steadily and keeps going no matter what button you press
Control panel is completely dead, nothing responds when you push Start or any cycle button
Dishwasher won't start a new cycle at all
Dishes come out cold and soaking wet even when you had the heated dry setting on
Water feels room temperature when you crack the door open mid-cycle
Can you reset a Kenmore dishwasher to clear the CLEAN-LIGHT-FLASHING code?
Press Heated Dry, Normal Wash, Heated Dry, Normal Wash within about 3 seconds. All the lights on the console will illuminate at once. That's your confirmation the board accepted it. Press Cancel to return to standby, or Start to run a short test cycle. Wait at least 5 minutes before running a full load. If the light comes back before the cycle finishes, there's still a live fault in the heater circuit that needs to be physically repaired.

Frequently Asked Questions
What is the most common reason for the clean light to flash?
Honestly? Burnt-out heating element, about 70% of the time. It's just a wear part that eventually gives out from constant heating and cooling cycles. I replaced three of them last month alone on different Kenmore models. The element works hard every single cycle, heating the water during the wash and heating the air during the dry. They're cheap to buy, usually $20-40, and not terrible to replace if you're comfortable pulling the kickplate and reaching under the tub.
Can I still use the dishwasher if the light is flashing?
Not really. The flashing clean light is a hard lockout and the control panel won't respond until you run the reset sequence. And even if you clear it and sneak a cycle in, you're washing dishes in cold water, which means nothing's actually getting sanitized. If you've got kids or someone in the house who's immunocompromised, that's actually a real concern. Fix it or don't run it.
How do I reset the flashing clean light on my Kenmore?
It's the 1-2-1-2 sequence. Press Heated Dry, Normal Wash, Heated Dry, Normal Wash, all within about 3 seconds. Every light on the console will come on at once. That's your sign it worked. Press Cancel to clear the codes or Start to run a short test. Fair warning though: if the underlying problem isn't fixed, that light's coming back. The reset clears the flag, it doesn't fix the cause.
What should the resistance be on a Kenmore heating element?
You're looking for 10 to 30 ohms. Set your multimeter to resistance mode, disconnect at least one wire from the element terminals first, then probe both terminals. Anything in that range is a healthy element. OL or infinite resistance means the coil's snapped. Something really low like 1 to 3 ohms means it's shorted. Both are bad and both mean a new element. Part number WPW10518394 fits a lot of Kenmore dishwashers if you need a quick reference.
Does a flashing clean light mean I need a new control board?
Almost never, at least not as your first move. I always test the element and thermostat first because boards are expensive, usually $80-150, and a heating element is $20-40. I'd say 80% of these calls end with a new heating element, not a new board. The only time I go straight to the board is if the element and thermostat both test good and the wiring is clean. Even then I check the heater relay specifically before condemning the whole board.
