To stop GE dishwasher lights from flashing, first ensure the door is fully latched and the Start button has not been accidentally bumped. If the Start light is blinking, the cycle was interrupted and needs to be resumed or cancelled by holding the Start button for three seconds.
When your GE dishwasher starts blinking like a Christmas tree, don't panic. Usually it's the door latch not clicking all the way in, or water got into the base pan and tripped the flood switch. I've also seen this happen a ton right after power outages. Ignore it long enough though and you're looking at potential water damage or a seized control board, so don't put it off.
OK so here's the deal. Flashing lights mean your dishwasher's stuck in limbo. It wants to run but something's telling it not to. Could be a $25 door latch, could be water pooled in the base pan, could just be a scrambled control board after a power blip. Most of the time this is totally fixable without calling anyone. I deal with this probably twice a week.

Symptoms You May Notice
The Start light blinks every second or so and won't stop, even after you close the door firmly and wait a minute.
Every single button on the panel lights up at once and none of them respond when you press them, like the whole board is frozen.
You hear the dishwasher beep three times and then nothing, just blinking, no motor, no water.
Display shows 1H or 2H while lights are flashing, which means it's in delay-start mode but something's blocking it from actually running.
Machine randomly stops mid-cycle and the panel starts flashing like it forgot what it was doing.
Can you reset a Ge dishwasher to clear the FLASHING-LIGHTS code?
Press and hold the Start button for three full seconds until you hear the drain pump kick on, then let it finish draining, about 90 seconds. If the lights are still going after that, go to your breaker panel and shut the dishwasher circuit off for 60 seconds, then restore power. When it comes back on the display should show normal standby without any blinking.

Frequently Asked Questions
Why is my GE dishwasher Start light flashing?
The Start light blinks when the cycle gets interrupted and the board's waiting for you to tell it what to do next. Most of the time it's because the door got opened mid-cycle, or the door didn't latch fully when you pushed it closed. Just hold the Start button for three seconds to cancel and drain. If that doesn't fix it, the door latch switch might actually be failing, which means the board thinks the door's open even when it isn't. That's a $25-45 part and pretty easy to swap yourself with a Phillips screwdriver and about 20 minutes.
Can a power surge cause GE dishwasher lights to flash?
Yeah, absolutely. GE control boards don't love power spikes. A surge can leave the firmware in a weird state where it just loops through a blink pattern and won't respond to anything. Good news is a hard reset at the breaker usually clears it and costs you nothing. Bad news is if the surge was strong enough to actually fry the board, you need a replacement. Control boards for GE dishwashers run $80-200 depending on the model. If a 60-second breaker reset doesn't clear it, that's probably where you're headed.
What does it mean when all the lights on the panel are flashing at once?
That whole-panel-going-crazy thing is usually a communication failure between the two boards in the machine. GE dishwashers have a main control board and a separate user interface board, and they talk through a ribbon cable or wire harness. First thing I check is whether that harness is plugged in firmly at both ends. If it's loose, push it in and try a reset. If the connection's solid, one of the boards has likely failed. I replaced both a GE UI board and control board on the same unit last week, which happens more than you'd think after a bad power event.
How do I get my GE dishwasher out of Demo Mode?
If your dishwasher's brand new or was just installed, there's a decent chance it's in Demo Mode, which makes lights blink and prevents real cycles from running. On most GE models you hold Heated Dry and Start at the same time for about five seconds until you hear a beep and the display changes. Some models use Wash Temp and Dry Boost instead. If neither combo works, pull up your model's installation guide because GE changed the button sequence a couple times across different production years. Demo Mode being the culprit is way more common than people realize on fresh installs.
Is it worth repairing flashing lights or should I just replace the dishwasher?
Honestly, fix it. Nine times out of ten you're looking at a door latch ($25-45), a free hard reset, or at worst a control board ($80-200). Even the worst case repair is a fraction of a new machine. The only time I tell someone to replace instead of repair is when the tub's rusted through or the motor's seized, and flashing lights almost never mean either of those things. If you can narrow it down using the steps above, you can probably fix this yourself in under an hour with basic tools.
