What Does Error Code C6 Mean on a GE Appliances Dishwasher?

Incoming water temperature too low.

The control detected that the incoming water temperature is below the minimum (about 120°F/49°C) needed for effective washing, so it may extend the cycle to add heat. On some newer GE/Profile/Café models C6 is reported as C7 for the same condition.

What Causes Error Code C6?

Here are the most common causes in order of frequency. Start with the most likely cause before moving to the next:

  1. 1
    Home water heater set below 120°F (49°C) 45% of cases
  2. 2
    Cold water sitting in the supply line 30% of cases
  3. 3
    Hot water used elsewhere during the cycle 15% of cases
  4. 4

Frequently Asked Questions

Can I keep using my GE Appliances Dishwasher when error C6 appears? +
You often can for a cycle or two, but the temperature issue behind C6 will keep interrupting normal operation until it is fixed. Plan the repair rather than ignoring the code.
What most commonly causes C6 on a GE Appliances Dishwasher? +
Across reported GE Appliances dishwasher repairs, the most frequent is home water heater set below 120°F (49°C) (45% of cases), cold water sitting in the supply line (30%), then hot water used elsewhere during the cycle (15%). Check them in that order before replacing any parts.
C6 keeps coming back after a reset — what should I check next? +
A reset only clears the stored C6 fault; if it returns, the temperature problem is still present. Move on to the physical checks — run the nearby hot tap first, then raise water heater temperature — since the code will reappear until the root cause is resolved. This is a beginner-friendly job needing only basic hand tools.
How much does it cost to fix GE Appliances Dishwasher error C6? +
A DIY repair typically runs $0–$40 in parts, versus $100–$220 for a professional service call, so handling it yourself saves around $100. Expect the work to take about 10–20 minutes.
