What C5 Means
C5 means the opposite of C1 - the control saw the pump-out finish sooner than it should have. GE's published checks are to verify the water supply is on, retry the cycle, and tap the float cover to un-stick it, because a dishwasher that never filled properly also has nothing much to pump out.
Common Causes of C5
- Water supply valve closed or partly closed
- Kinked or restricted inlet line, or a clogged inlet screen
- Float stuck in the raised position so the control thinks the tub is full
- Water level or pressure sensor reporting incorrectly
🔧 One Safe Check You Can Try
Check that the household shut-off valve for the dishwasher (usually under the sink) is fully open and that the inlet line is not kinked. Tap the float dome inside the tub to make sure it moves freely. Then run a short cycle and watch whether water enters normally in the first minutes. If the tub fills properly and C5 still appears, the level-sensing side needs a technician rather than another retry.
⚠ Why You Shouldn't Go Further Than That
- None for the supply-valve and float checks.
- Sensor and inlet-valve testing is done with a meter on live terminals behind the lower access panel, next to the water connection.
- Damage caused during a repair attempt may not be covered - check your warranty terms first.
Opening a panel to inspect or repair something yourself doesn't automatically cancel your manufacturer's warranty — but it can risk accidental damage, and some manufacturers do have specific service conditions. Check your product's warranty terms, or ask us, before deciding.
