What Does Error Code C5 Mean on a GE Appliances Dishwasher?

Drain failure — dishwasher not draining.

The C5 code fires when the control board runs the drain pump but the tub does not empty within the expected time window, leaving standing water. The board infers this from cycle timing rather than sensing pump current directly. It differs from C4 (typically a fill or water-level problem) and FL (a leak or float-related fault), since C5 points specifically at obstructed drainage — a clogged filter, kinked hose, blocked disposal, or a pump that spins without moving water.

Models affected: GE dishwashers that display alphanumeric fault codes, including models such as GDF630PSMSS, GDT665SSNSS, and GDP630PYRFS; broadly, GE full-size built-in dishwashers with electronic controls

What owners report: Owners commonly report C5 appearing at the end of a cycle with an inch or more of water sitting over the filter, and the quick win is usually cleaning the filter or clearing the garbage disposal knockout plug on a new install. A hose that isn't high-looped can trigger it intermittently even when nothing is clogged.

Frequently Asked Questions

Can I keep using my GE Appliances Dishwasher when error C5 appears? +

It is not advisable. The dishwasher may still power on, but running it while C5 is active can worsen the drainage fault or damage related parts. Treat it as a soon-as-possible repair.

What most commonly causes C5 on a GE Appliances Dishwasher? +

Across reported GE Appliances dishwasher repairs, the most frequent is drain filter clogged with food particles (50% of cases), drain hose kinked or improperly high-looped (25%), then garbage disposal blockage (15%). Check them in that order before replacing any parts.

C5 keeps coming back after a reset — what should I check next? +

A reset only clears the stored C5 fault; if it returns, the drainage problem is still present. Move on to the physical checks — clean the drain filter, then check the drain hose — since the code will reappear until the root cause is resolved. This is a moderate job — a multimeter and some disassembly are usually involved.
