GE Dishwasher Error Code C3: Quick Guide to Causes and Fixes

What Is GE Dishwasher Error Code C3?

The C3 error code on a GE dishwasher usually points to a drainage issue. It means the dishwasher is taking too long to drain water during or after the wash cycle.

When this happens, the control system stops the cycle to prevent further problems.

In most cases, the issue is related to a clogged drain filter, blocked drain hose, or a problem with the drain pump.

Key Signs of the C3 Error

You may notice several symptoms when this error appears:

• Dishwasher stops before finishing the cycle

• Water remains at the bottom of the tub

• The C3 code appears on the control panel

• The dishwasher attempts to drain repeatedly

These signs typically indicate that the appliance cannot remove water properly.

Main Causes of GE Dishwasher C3 Error

Below are the most common reasons this error occurs.

Clogged Drain Filter
Food debris, grease, and small particles can block the filter and slow down drainage.

Blocked Drain Hose
A bent or clogged hose can prevent water from flowing out of the dishwasher.

Garbage Disposal Blockage
If the dishwasher is connected to a garbage disposal, a blockage there can stop proper drainage.

Faulty Drain Pump
A malfunctioning pump may not be able to push water out of the appliance.

Improper Drain Hose Installation
If the drain hose is installed incorrectly, water may not flow out efficiently.
