GE Dishwasher C6 Error Code

Incoming water too cold. Here is what it means and how to clear it, easiest fix first.

How to fix GE C6

1. Run the hot tap first

   Before starting the dishwasher, run the hot water at the kitchen sink until it is hot.

2. Adjust your water heater

   Make sure the water heater is set high enough to deliver at least 120°F (49°C), and avoid showers or laundry at the same time as the dishwasher.

3. Use longer cycle options

   Choose options that add heating time, such as a higher-temperature wash, if your model has them.

When to call a technician

If the water at the sink is hot enough and C6 still appears, schedule service to check the temperature sensor.

Frequently asked questions

What does C6 mean on a GE dishwasher?

The water entering the dishwasher is colder than it should be. GE wants at least 120°F (49°C) at the dishwasher.

Can I fix GE C6 myself?

Usually, yes. Most C6 problems clear with simple checks you can do at home. Start with the first step above: run the hot tap first.

What if C6 keeps coming back?

A code that returns after a reset and the checks above usually means a part is wearing out. Note when C6 appears (which cycle, how often) and have your model number ready; it helps a technician bring the right part on the first visit.
