When the Normal light flashes, your dishwasher is stuck in a fault mode usually caused by a stuck button or moisture in the console. Try a hard reset by disconnecting power at the breaker for five minutes to clear the control board memory.
Fifteen years of service calls and honestly about 60% of these end with a $12 cleaning job and a reseated cable. But ignore it and the moisture that's causing the blink will keep spreading. Give it a month and you're replacing a fried control board instead of unsticking a button. Don't let a $30 fix turn into a $200 repair.
OK so here's the deal. The control board watches all the buttons constantly, and if it sees any button held for more than 30 seconds it shuts down and starts flashing. Kenmore dishwashers, especially the older 665 series, are notorious for this because their door seals dry out and let steam crawl up into the console. Pretty fixable once you know what you're looking at.

Symptoms You May Notice
The Normal cycle light blinks non-stop and nothing else on the console responds, like the whole panel just locked up.
You press Start and nothing happens. No water filling, no motor humming, just that light blinking at you.
The dishwasher stops dead mid-cycle and the Normal light starts blinking, leaving dishes sitting in cold soapy water.
One specific button on the panel feels flat or doesn't click when you press it, while everything else clicks fine.
Dishes come out wet even with Heat Dry on for a few weeks, then one day the blinking starts out of nowhere.
Can you reset a Kenmore dishwasher to clear the NORMAL-LIGHT-BLINK code?
Press Heat Dry, Normal, Heat Dry, Normal in sequence. You've got about 6 seconds to hit all four buttons, so move with some purpose. All the lights on the panel should flash on at the same time if it worked. Then press Start to kick off a short reset cycle. It runs maybe 2 minutes, drains the tub, and clears whatever error codes the board has stored.
Follow these steps in order. We start with the easiest external fixes before opening up the machine.

Frequently Asked Questions
Can I still run the dishwasher if the light is blinking?
Honestly, probably not. The board locks everything out on purpose when that blink starts because it thinks there's a stuck button or a short, and running a cycle in that condition could cause overheating. That said, I've seen cases where a quick 5-minute reset clears it completely and the machine runs fine for months. Try the hard reset first. If you get a full cycle without the blinking coming back, you might be fine for now. But keep an eye on it because if the root cause is moisture, it'll come back.
Does this blinking light mean I need a new control board?
Not necessarily, and don't let anyone sell you one before checking the touchpad first. The user interface panel fails way more often than the main control board on these Kenmore units. I've replaced probably three touchpads for every one main board on the 665 series. The ribbon cable connection is the first thing to check, takes five minutes and costs nothing. A new touchpad assembly runs $40-$80 depending on your model. A main control board is $100-$200. Always go cheap first.
Why did my Kenmore dishwasher start doing this suddenly?
Steam's the usual suspect. Your door gasket dries out a little over time and steam starts sneaking past it during the hot dry cycle. That steam gets up behind the console and leaves a thin film of moisture across the keypad circuits. Over time it creates a partial short that the board reads as a stuck button. It usually hits right after a long hot cycle, or it can show up out of nowhere one morning because the moisture finally crept far enough to cause a consistent short.
How do I know if it is the heater or the keypad?
Count the blinks. A constant, steady blink with no real pattern is almost always the keypad or a loose ribbon cable. If it blinks seven times, stops for a second, blinks once, and repeats that sequence, that's the heater error. Grab a multimeter and check the element resistance before you tear apart the door panel. You want 10-30 ohms. Open circuit means it's burned out. That's a $30 part and a way easier fix than messing with the console.
Is it worth repairing an older Kenmore dishwasher with this issue?
Depends on the age and what actually needs replacing. Under 8 years old with a stuck button or bad ribbon cable? Fix it, you're talking $20-$80 and maybe an hour of your time. But if the machine is 12+ years old and you're looking at a new touchpad plus a main control board, do the math. Those two parts plus labor can run $250-$400 total, and at that age the water inlet valve and pump are probably not far behind. Sometimes the honest answer is just a new machine.
