The short answer
C5 is the mirror image of a slow drain: the control expected the pump-out to take a certain time and it ended too soon. The usual reason is that there was less water in the tub than the cycle assumed, or that the level sensing is reporting empty early — not that the pump is too strong.
GE dishwasher code as the manufacturer publishes it
Reference| Code | Meaning |
|---|---|
| C5 | The pump out time is too short. |
What you observe alongside the code
- The drain note stops almost as soon as it starts — Noticeably shorter than the machine used to sound.
- Dishes come out under-washed or still dry in patches — Not enough water in the tub to reach the upper rack properly.
- Very little water visible in the sump at any point — You can often see the low fill through the door during a cycle.
- NEAR MISS — no water at all and a low-water warning instead — A complete fill failure has its own code and its own page.
What triggers it, most likely first
- A partly closed supply valve or a restricted inlet screen — First: the tub never reached its intended level, so the pump empties it early. The valve under the sink is the single most common finding.
- A weak or intermittent water inlet valve — Second: the valve opens but passes less than it should, which produces the same short fill every cycle rather than now and then.
- Level or pressure sensing reporting empty early — Third: a fouled sensing chamber reads a lower level than is really there, and the control stops the pump on that reading.
- An air-gap or standpipe siphon pulling the tub down mid-cycle — Last: water leaves without the pump, so when the drain step arrives there is nothing left to move.
Check in this order, and why
- Open the supply valve fully and check the fill by eye — The cheapest check, and it resolves the majority of these.
- Watch one fill step from start to finish through the door — A fill that stops early names the valve; a normal fill sends you to sensing.
- Look for water leaving the tub between steps — A tub that empties itself points at a siphon, not at the pump.
- Clean the sensing chamber and filter last — Only after the fill has been proved good.
Clearing the code, then the owner-safe checks
- Open the supply shut-off under the sink fully — Quarter-turn valves get knocked closed. No tools.
About 5 min
- Clean the inlet screen at the fill valve — Close the supply first; the screen at the hose connection clogs with scale and grit.
Tools: pliers, towelAbout 20 min
- Run a rinse cycle and time the fill and the drain — Both short together means fill; a normal fill with a short drain means sensing.
About 30 min
- STOP HERE if the fill is normal and the drain still ends early — That is the pressure sensing or the control, and it needs a technician.
Before you open anything
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. On a built-in dishwasher the supply is not switched at the door, so the breaker is the only reliable off. Leave the door latch switch wired as it is: it stops the pump and the heater the moment the door opens.
When this code is a service call
Call when the tub fills normally and the pump-out still finishes early, because the remaining suspects are the pressure sensing and the control board. Call sooner if the heater is running during a short-filled cycle: heating a tub with too little water in it stresses the element and can mark the tub floor.

Which model lines this reading applies to
This reading of C5 applies to current GE and GE Profile built-in dishwashers with a digital display or a lit status row, the platform on which the manufacturer publishes it. A timer-driven machine with no display never shows it, and a Monogram or Hotpoint-badged unit can use the same characters for a different fault.
