C6 in one line
Cold water inside the machine is what C6 reports on a Kenmore 363 electronic-control dishwasher. Before blaming the dishwasher, the manual looks at the supply feeding it.
Measuring the supply
Let hot water run from the sink tap for a full minute.
Catch some in a glass.
Check it with an accurate thermometer.
A reading under 120 degrees F means the water heater setting needs adjusting, and the manual wants that done in small steps so nobody is scalded.
When the supply temperature is normal
Past that point the suspects are the temperature sensor and the control board, and either of them could have failed. A technician does the testing.
For a C6 that stays after the water heater check, we can arrange a technician in San Francisco and around the Bay Area; call (415) 825-6393 or open Kenmore dishwasher repair. Have your thermometer reading and the model number written down.
Model compatibility: Kenmore reuses codes across series and model years, so C6 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.

What this code means
C6 reports that the water temperature is too low.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
