A GE C2 error means your dishwasher failed to drain within the required time limit. Nine times out of ten, this is caused by a clog in the drain hose or a blocked garbage disposal inlet.
So when I show up and see a C2 on a GE dishwasher, there's almost always a puddle of nasty standing water in the tub. Ignore this one and you're risking a burnt-out drain pump, which turns a free fix into a $80+ repair real fast. The good news is that 80% of the time it's something you can clear yourself in under 30 minutes, no parts needed.
The C2 is honestly the most common drain fault I see on GE dishwashers, and I've been seeing it for years. Your machine tried to empty the tub but the water just sat there until the timer gave up. You'll find it full of gross, soapy water when you open the door. The fix is usually cheap, maybe even free if it's just a kinked hose or a plugged air gap.

Garbage disposal knockout plug20%
Faulty drain pump motor15%
Sump debris or filter blockage10%
Symptoms You May Notice
Standing water in the bottom of the tub after the cycle ends, sometimes an inch or two deep and full of dirty foam
A loud humming or grinding noise during the drain portion of the cycle, like the pump is working overtime but water isn't going anywhere
Dishwasher freezes mid-cycle with C2 on the display and won't respond to button presses
Dishes come out wet and dirty because the machine couldn't drain and basically abandoned the rest of the cycle
Water drains really slowly during a manual reset attempt, taking 3-4 minutes when it normally clears in under 60 seconds
Can you reset a Ge dishwasher to clear the C2 code?
Press Start/Reset once and let the machine attempt to drain for 60-90 seconds. If water clears out of the tub, the code goes away on its own. If it doesn't drain, unplug the unit from the wall or flip the breaker for 30 seconds to clear the control board memory. Don't just keep hammering Start, that won't help if there's still a physical blockage.

Frequently Asked Questions
Can I still run my dishwasher with a C2 error?
Don't do it. Running it again with standing water in the tub means you're asking the pump to work harder on a problem it already gave up on. That's how you turn a free fix into an $80 pump replacement. Clear the blockage first, then run a short rinse cycle and watch it. Seriously, just take the 20 minutes to check the hose and filter before you run another load.
How do I clear the C2 code from the display?
Hit Start/Reset once. The machine'll try to drain for about 60-90 seconds. If the water moves and the tub clears, the code disappears on its own. If water's still sitting there after that drain attempt, pull the plug from the wall or flip the breaker for 30 seconds to wipe the board's memory. Heads up though: the code's gonna come right back on the next cycle if you haven't actually fixed the blockage. The reset doesn't fix anything, it just clears the display.
Why does my GE dishwasher only show C2 at the end of the cycle?
Your dishwasher actually drains several times during a full cycle, between the wash phase and each rinse. If you've got a partial clog, the pump might barely stay ahead of it during those shorter mid-cycle drains, but by the final long drain it just can't keep up and the timer runs out. It's kind of like how you can run on a bad knee for a while before it finally gives out. The problem's been there the whole time, the last drain just exposed it.
Does a C2 error mean I need a new control board?
Almost definitely not. In 15 years I've replaced maybe three boards for a straight C2 code, and in all those cases the pump had been failing for months and eventually sent a spike that took the board with it. If your board's actually bad, you'll usually see other weirdness too, like buttons not responding or the display acting up randomly. For C2 alone, always check the physical stuff first. Save yourself the $150-250 board replacement.
Will Drano or chemical drain cleaners fix a C2 error?
Hard no. Caustic drain cleaners can damage the rubber door gasket, the pump seals, and the spray arm o-rings inside a GE dishwasher. And they won't even work anyway, because what's blocking your drain is almost always a solid chunk of food, broken glass, a jar lid, or a piece of plastic wrap. You need to physically pull it out. If you've already poured chemicals in there, run a full cycle with a cup of white vinegar in the bottom of the tub to neutralize it before you do any other work.
How much does it cost to fix a C2 error?
If it's a clog, nothing. Free. Maybe 20 minutes of your time. If the drain pump is actually dead, you're looking at $40-80 for the part depending on the model, and about an hour of labor if you're doing it yourself. A shop'll charge you $150-250 total for a pump replacement including the service call. Honestly, I'd try every DIY step first before calling someone out, because 7 out of 10 of these calls I go on, the fix was a clogged filter or a kinked hose.
