GE dishwasher C5 error code

Dishwasher

GE dishwasher C5 signals the tub did not fill quickly enough — similar to washer fill faults. On GDT665 models, confirm the hot water valve under the sink is fully open and the inlet screen at the dishwasher is clear. C5 after a plumbing shutoff often clears once air is purged from the line.

How to fix C5

Confirm the hot water supply valve is fully open.
Run hot water at the sink until it flows hot — purges cold slug in the line.
Shut power, disconnect the inlet hose, and rinse the screen at the dishwasher valve.
Restore water and power, then start a rinse cycle.
Replace the water inlet valve only if fill remains slow with good supply pressure.

Call a pro when: Call a plumber for low hot-water pressure at all fixtures.

What C5 means

Pump-out time is too short — often a closed water supply or a stuck float.

Likely causes

Most likelyClosed supply or stuck float

A closed valve or a stuck float cup prevents a normal fill, so drain time looks too short.

Check: Open the supply valve. Tap the upside-down cup float in the front-left of the tub floor.

Est. cost: $0–$0

PossibleClogged inlet screens

Sediment in the hose screens restricts flow even when the valve is open.

Check: Shut off water, disconnect hoses at the appliance, and rinse the mesh screens.
