GE Dishwasher C5 Error Code — What It Means

The C5 code shows the dishwasher did not take in enough water before the pump out cycle ran. The control reads a short fill and stops.

The common causes are a supply problem or a restricted water inlet valve. A stuck float can also keep the tub from filling.

Jump to Fix

Common Causes

Supply valve not fully open The shutoff under the sink is partly closed and limits the fill.
Clogged inlet valve screen Sediment on the inlet valve screen restricts water into the tub.
Stuck float switch A float held in the up position stops the dishwasher from filling at all.
Failed water inlet valve A weak valve solenoid no longer opens enough to fill in time.
Loose inlet valve wiring A bad connection at the valve keeps it from energizing fully.

Step-by-Step Fix

Cut power at the breaker before working on the valve or float.
Confirm the water supply valve under the sink is fully open.
Check the float in the tub floor and free it if it sticks up.
Disconnect the fill line and pull the inlet valve screen for cleaning.
Rinse the screen clear, reseat it, and check the valve wiring is snug.
Restore power and run a short cycle to confirm a full fill.
If the valve screen is clean but fill stays short, replace the inlet valve.
