GE Dishwasher Won't Start: Power Is On but Cycle Won't Begin
Quick Answer
GE Dishwasher not starting: check that the door or lid is fully closed first, then verify the breaker is on and child lock is not enabled. Try a power reset (unplug 2 minutes). If still dead, test the door switch and thermal fuse with a multimeter.
Nine times out of ten when I roll up to a GE that won't start, it's the door latch or control lock and nothing else. But if you've already tried the basics and it's still dead, don't panic. A blown thermal fuse or a fried control board are both fixable. Just don't ignore it and leave standing water sitting in there, because mold sets up fast and then you've got two problems.

GE Dishwasher Won't Start: Power Is On but Cycle Won't Begin
OK so your GE display is lit up fine but nothing happens when you press Start. That's almost always a communication breakdown between the door latch and the control board. The machine thinks the door's still open, so it won't run. Before you go buying a new control board, let's rule out the simple stuff first. Control lock, delay start, and that annoying 5-second timing window catch a ton of people off guard.
Most Likely Causes
Based on aggregated repair data, here is the probability breakdown for this error code:
Control lock (child lock) is active40%
Door latch not producing a firm click, latch switch not closing24%
Cycle not fully selected before pressing Start14%
Error code from previous cycle preventing new start12%
Delay start option was set accidentally10%
Symptoms You May Notice
The display is fully lit with cycle options showing, but pressing Start does absolutely nothing, not even a beep.
You press Start and get exactly one beep, then silence. Machine just sits there like you never touched it.
A padlock icon is glowing on the panel or the word LOCK is showing, and none of the buttons respond at all.
Display shows something like 2h or 4h and counts down instead of starting because Delay Start got set without you realizing.
Lights on the panel are blinking in a weird pattern after you press Start, which means an old error code is still hanging around in memory.
Can you reset a Ge dishwasher to clear the WONT-START code?
Press and hold Start or Reset for a full 3 seconds until the panel beeps or the lights flash once, which means it cleared the command. If the display is completely frozen and nothing responds, go flip the breaker off and leave it off for a full minute, not just 10 seconds. Flip it back on, wait for the display to come back up, then select your cycle and hit Start within 5 seconds.

Diagnostic Checklist
Follow these steps in order. We start with the easiest external fixes before opening up the machine.
Did the fix not work?
If the problem comes back after following these steps, a component has permanently failed and needs replacement. Check the specific error code your dishwasher is showing:
ConditionIf Open (OL) or infinite, replace component.
Replacement Parts
If your diagnostic testing proves the component has failed, you will need a replacement. We recommend OEM parts over aftermarket for water-handling components.

Frequently Asked Questions
Why does my GE dishwasher beep once when I press Start but not do anything?
One beep usually means the control board heard you but won't allow the cycle to start. On GE units, that's almost always because the door switch circuit is open. Even if the door looks shut, if that tiny internal switch doesn't click, the board stays in standby as a safety thing. I also see this when Control Lock is on but the icon is so small people miss it. Give the door a really firm push and scan the display carefully for any lock icon before you start pulling things apart.
How do I know if my GE dishwasher door latch is bad?
First, does the door stay tight against the tub or does it gap even a little? If it gaps, the latch isn't grabbing. Second, get your multimeter and check continuity across the two terminals on the latch switch while you manually press the plunger with your thumb. A working switch shows 0 ohms. If it stays open with no reading, the switch is dead. It's one of the most common failures I see on GDT and GDF models. The whole latch assembly usually runs $25-60 depending on your model, and it's a pretty straightforward swap.
My GE dishwasher was working fine yesterday and just stopped starting. What happened?
Honestly, this happens all the time and it's usually the 5-second timing thing or Control Lock got bumped without anyone noticing. But if it literally worked one day and was dead the next with no warning, check your breaker first. And look under the sink because sometimes there's a GFCI outlet under there that tripped and nobody realized the dishwasher was plugged into it. Also look for any blinking pattern on the display, that's the machine trying to tell you something went wrong at the end of the last cycle.
Can a power surge cause my GE dishwasher to stop starting?
Yeah, absolutely. A surge can corrupt the control board's memory and leave it stuck in a weird state where it won't accept new commands. First thing to try is a hard reset at the breaker, leave it off for a full minute. If that doesn't clear it, the control board itself might be fried. I see it happen after summer storms pretty regularly. If you don't have a surge protector on that circuit, it's worth adding one. They run $15-20 and can easily save you a $200 board replacement.
How much does it cost to fix a GE dishwasher that won't start?
Depends a lot on what's actually broken. Door latch assembly is $25-60 in parts and maybe an hour of your time if you're handy. Control lock or a software glitch costs you nothing to fix yourself. Thermal fuse is $8-15 for the part. Control board is where it gets painful, those run $150-300 for the part alone, plus labor if you hire a tech. Personally, anything under $150 in parts is worth fixing on a GE that's under 8 years old. Over that on an older machine, think hard about whether it makes sense.
Is it worth repairing a GE dishwasher that won't start, or should I just replace it?
Here's how I think about it. If your GE is under 7 years old and the repair is under $200, fix it. GE builds solid machines and the parts are easy to find at reasonable prices. If it's 10+ years old and you're staring down a new control board plus labor, that's getting close to what a decent entry-level replacement costs. Had a customer last week with a 12-year-old GDT facing a $280 board repair. She bought a new one and I don't blame her. But if it's just a latch or a fuse? Fix it. Don't let a $30 part send a good machine to the landfill.
