GE Dishwasher Error Code C5

The C5 code means the dishwasher control detected two back-to-back pump-out cycles that each lasted less than 6 seconds. This tells the control that little or no water entered the tub during the last two fill cycles. The root cause is typically a water supply problem, a faulty inlet valve, a tub leak, or a clogged pump inlet.

You should not continue running the dishwasher while the C5 code is active. If the cause is a water leak, running the unit could cause water damage to flooring or cabinetry. Resolve the underlying issue before resuming normal operation.

Repair costs depend on the specific cause. If only a cleaning of the pump inlet or adjustment of the supply valve is needed, costs may be minimal. Replacing a water inlet valve typically runs in the range of $50 to $150 for parts and labor, while a diverter valve replacement or leak repair could fall in the $100 to $250 range depending on parts and the time required.

Some causes of C5 are easy DIY fixes, such as opening a closed water supply valve or cleaning a clogged pump inlet strainer. However, replacing a water inlet valve, diverter valve, or repairing a tub leak may require disassembly of the dishwasher and some mechanical skill. If you are not comfortable working with water supply connections or appliance components, calling a technician is the safer choice.

Pressing Reset will clear the active fault and allow the dishwasher to attempt a new cycle. However, if the underlying problem is not corrected, the C5 code will return after two more consecutive short pump-out cycles. A reset alone is not a repair, it is a way to restart after you have addressed the root cause.
