GE Dishwasher C5 Error Code

Drain time too short (underfill). Here is what it means and how to clear it, easiest fix first.

C5
Moderate DIY

The pump-out finished sooner than expected, which usually means not enough water got into the tub. A partly closed supply valve, low water pressure, a stuck float or a weak inlet valve can cause it.

GE notes that not every code appears on every model; check your owner's manual.

Safety first: unplug the dishwasher (or switch off its breaker) before touching filters, hoses or panels. If you smell burning or gas, or see water near the outlet, stop and call a professional.

How to fix GE C5

  1. Check the water supply

    Make sure the dishwasher's supply valve under the sink is fully open and the supply line is not kinked, then rerun the cycle.

  2. Free the float

    With power off, tap the float cover on the tub floor so the float moves freely.

  3. Look for leaks

    Check the door gasket and the area around the tub for water or dampness, which can mean water is escaping instead of filling the tub.

When to call a technician

If water supply is good and C5 returns, a technician should test the inlet valve and check the pump inlet and diverter.

Frequently asked questions

What does C5 mean on a GE dishwasher?

The pump-out finished sooner than expected, which usually means not enough water got into the tub. A partly closed supply valve, low water pressure, a stuck float or a weak inlet valve can cause it.

Can I fix GE C5 myself?

Often. The first steps above are safe checks a homeowner can do. If they don't clear C5, the cause is likely a worn part that needs replacing.

What if C5 keeps coming back?

A code that returns after a reset and the checks above usually means a part is wearing out. Note when C5 appears (which cycle, how often) and have your model number ready; it helps a technician bring the right part on the first visit.
