GE Dishwasher C3 Error Code — What It Means

The C3 code reports that the dishwasher failed to drain. The control senses water still in the tub after the pump out cycle.

Start with the cheap fixes. A packed filter or a small object stuck in the drain pump causes most C3 codes before the pump itself is at fault.

Common Causes

Clogged filter or sump Food residue fills the filter and blocks water from reaching the pump.
Jammed drain pump impeller Glass shards or a fruit pit lock the impeller so it cannot spin.
Blocked or kinked drain hose A clog or sharp bend in the hose stops the outflow.
Disposer plug not removed A new disposer still holding its knockout plug leaves the drain dead ended.
Failed drain pump The pump motor no longer runs and the water has no way out.

Step-by-Step Fix

Cut power at the breaker and remove standing water with a cup and sponge.
Pull the bottom filter and clean the sump and drain area thoroughly.
Check the drain pump inlet for glass, seeds, or plastic locking the impeller.
Disconnect and flush the drain hose to confirm it runs clear.
If the unit feeds a disposer, make sure the knockout plug is gone.
Restore power and run a drain cycle to confirm the tub empties.
If the path is clear and water stays put, plan to replace the drain pump.
