GE Dishwasher C2 — What It Means & How to Fix It
Draining ran well past the time GE allows — about seven minutes — pointing to a heavier blockage than the milder C1, though the things to check are the same trio.
What this code means
C2 is C1's more serious sibling: the pump-out cycle exceeded roughly seven minutes, so the water did eventually leave but only against real resistance. The blockage usually sits further along the same path — a heavily fouled air gap, a hose clogged rather than merely kinked, or a disposer outlet packed with waste. GE's first instruction is to press RESET to silence the alarm, then deal with the restriction.
C2 sits between the slow-drain C1 and the no-drain C3 on GE's C-code dishwashers. Because the displayed set varies by model, confirm against your model's fault list on the door edge or tub rim if your machine shows different codes.
Most likely causes
| Cause | How likely | DIY-fixable? |
|---|---|---|
| Drain hose clogged or crushed along its run | Common | Partly — clear visible sections |
| Air gap heavily fouled | Common | Yes — unscrew cap, rinse |
| Disposer outlet or drain tee packed with waste | Common | Yes — run disposer, clear tee |
| Drain pump struggling against partial failure | Occasional | No — technician job |
What you can try yourself
- Press RESET (often the Start/Reset pad) to stop the beep — C2 leaves the alarm sounding until you acknowledge it.
- Run the garbage disposer fully, then check the drain tee where the dishwasher hose joins it for packed debris.
- Detach the drain hose at the disposer or tee end with a towel ready, and confirm it flows freely; a hose clogged internally rather than just kinked is common at C2.
- Clear and rinse the countertop air gap, a frequent choke point that worsens from C1 to C2 as it fills.
- Reconnect everything, restore power, and run a rinse cycle to confirm the tub now empties within a minute or two.
When to call a technician
- C2 persists after the hose, air gap, and disposer path are all confirmed open — the pump may be failing.
- The pump runs loudly or only intermittently during the long drain.
- The code advances to C3, no drain at all, on the next cycle.
Typical professional repair cost: A clogged external path costs nothing to clear. A failing drain pump runs about $150–$300 replaced with labor.
Frequently asked questions
How do I clear the C2 alarm on my GE dishwasher?
Press the RESET pad, often the Start/Reset button, to stop the beeping. That only silences the alarm — the slow-drain cause still needs clearing, or C2 will return on the next wash.
C2 keeps coming back even though water drains eventually — why?
A partial blockage lets the pump win in the end but only past the time limit, so the code fires every cycle. Look for a hose clogged internally or a disposer outlet packed with waste rather than an obvious kink.
Is C2 worse than C1?
Yes. C1 flags a mildly slow drain; C2 means the pump-out took far longer, roughly seven minutes, which usually means a heavier blockage further along the path. The checks are the same, but C2's restriction is more stubborn.
Related GE codes
- GE Dishwasher C1 Your GE dishwasher is draining, but too slowly for the control's liking — the water path is partly restricted, usually at the air gap, the drain hose, or a disposer that hasn't been run.
- GE Dishwasher C3 The dishwasher didn't drain at all, and GE's first move for C3 is a brief power reset — if water still won't leave afterward, the drain path or pump needs attention.
- GE Dishwasher C4 C4 means the dishwasher refilled twice after a power interruption, which usually traces to a stuck overfill float or a clogged sump rather than anything electrical.
- GE Dishwasher C5 C5 fires when the drain finishes far too quickly, which normally means there was little water to pump out — a supply that's off, a slow fill, or a float telling the control the tub is empty.
