What you can check yourself
0 / 4 checked
- For C3 (will not drain) or FTD/F56, check the drain hose for kinks and clean the filter at the bottom of the tub.
- For C4 (filled twice after a power failure), this usually resolves itself once the float switch resets on its own — run a normal cycle and see if it clears.
- For H2O (low water), confirm the water supply valve is fully open and check for a kinked inlet hose.
- For LEAK DETECTED or 999, check underneath and around the dishwasher for visible water before running it again.

Call a technician for LEAK DETECTED if you find actual water, for C6/C7 (water temperature problems), or for any code that returns right after you've checked the filter and hose.
What C1 and C2 actually measure
C1 and C2 are both about how long the pump-out (drain) step takes — C1 means a single pump-out exceeded 2 minutes, C2 means the total pump-out time across the cycle exceeded 7 minutes. Both point to the same root causes as C3: a clogged filter, a kinked hose, or a blocked drain line, just caught at an earlier stage.
C8: an easy one to miss
C8 means the detergent cup is physically blocked from opening — sometimes by a tall item loaded too close to the dispenser, sometimes by hardened old detergent. Rearranging the load or cleaning out the dispenser resolves this one more often than any other fix on this list.
A note on this brand's codes: GE labels some displays as "fault" or "function" codes rather than strict errors — 1H, 2H and similar simply indicate a delay-start setting, not a problem.
