GE Dishwasher C3 — What It Means & How to Fix It
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.
What this code means
C3 reports a complete failure to drain during the cycle. GE treats it first as a possible control glitch: cutting power for about 30 seconds and restoring it clears a surprising number of one-off C3s. If the code returns, the problem is real — a fully blocked path or a pump that isn't running — and water will be standing in the tub floor.
C3 is the most severe of GE's drain codes, above the slow-drain C1 and the very-slow C2. The exact codes shown differ by model; if yours displays something else for a drain failure, the fault list for your model number is the reference.
Most likely causes
| Cause | How likely | DIY-fixable? |
|---|---|---|
| One-off control glitch that clears on reset | Common | Yes — power reset |
| Drain hose fully blocked or pinched shut | Common | Partly — visible sections |
| Disposer knockout plug never removed (new installs) | Common after installs | Yes — hammer + screwdriver |
| Drain pump failed or jammed | Occasional | No — technician job |
What you can try yourself
- Switch the dishwasher off at the breaker or wall switch for about 30 seconds, restore power, and run a short cycle — GE's first remedy for C3 is this reset.
- If water is standing in the tub, sponge out what you can so you can inspect, then twist out the filter in the tub floor and clear the sump opening beneath it.
- Trace the drain hose under the sink for a hard kink or a section crushed flat behind stored items.
- If a garbage disposer was recently installed, unplug it and confirm the knockout plug at the dishwasher inlet was punched out — a sealed plug stops draining completely.
- Restore power and test; if the tub empties briskly, the blockage is gone.
When to call a technician
- C3 returns after a power reset with the hose and disposer path confirmed clear — the drain pump has likely failed.
- The pump is silent during the drain phase, or hums without moving any water.
- Water remains in the tub across several cycles despite clearing everything reachable.
Typical professional repair cost: A reset or a cleared blockage costs nothing. A failed drain pump typically runs $150–$300 with labor; a control fault behind a recurring C3 can reach $200–$450.
Frequently asked questions
Will a power reset fix a GE C3 code?
Sometimes. GE's first suggested step is cutting power for about 30 seconds, because a one-time control glitch can throw C3. If the code comes straight back, though, you have a genuine drain problem to clear rather than a glitch.
Why won't my GE dishwasher drain at all with a C3?
A complete no-drain usually means the path is fully blocked — a hose pinched shut, a never-removed disposer knockout plug, or a jammed pump. Standing water in the tub floor is the visible sign, versus the slow-but-eventual drain behind C1 and C2.
Is standing water with a C3 an emergency?
It isn't dangerous, but don't keep starting cycles — that just refills a tub that can't empty. Cut the power, sponge out the water so you can inspect, and work through the drain-path checks before running it again.
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 C2 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.
- 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.
