Quick answer
Overfill/float/drain-sump condition; unit filled twice after power failure or float/drain issue.
Model compatibility: GE reuses codes across series and model years, so C4 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
Overfill/float/drain-sump condition; unit filled twice after power failure or float/drain issue.
Signs
Symptoms you may notice
The appliance may refuse to continue until water level drops.
The cycle pauses or ends before a normal drain is complete.
The fault may appear only when the appliance draws more current.
The cycle may stop early or repeat a fill attempt.
Why it happens
Possible causes
A clogged user-serviceable filter, sump area, drain hose, or household drain connection.
A harness or control fault in the fill circuit.
A control/inverter output problem that prevents the pump from running correctly.
A kinked inlet hose or debris at an inlet screen.
A water valve that does not open or close correctly.
Before you call
Safe checks you can make
These are simple, non-hazardous checks only. If anything is unclear, stop and contact a technician.
Do not open a live terminal block, receptacle, or junction box as a consumer troubleshooting step.
Check the user-cleanable filter or sump area only where the owner’s manual identifies it as a maintenance point.
If the model uses removable inlet screens that the owner’s manual allows the user to inspect, check for obvious debris without dismantling the valve.
Inspect the visible drain hose for kinks, crushing, or a sharply raised/incorrect route.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
