Basically don't run the washer unless both your hot water and cold water are ON. HF = Hot Fluid pressure fault, I would imagine CF would be cold fluid pressure fault. I thought the machine is suppose to be able to heat up the water, but apparently not on its own. The problem with these dumb error codes. I just want to continue where the cycle left off. Why the FF does it happen 20-30 minutes into the cycle; stupid. It was a sanitary cycle; hence the expectation of heating up the hot water, and the cold water is 3/4 pipe so no pressure problem. They put a sensor on the hot water valve; thx for nothing Kenmore...like the most useless of sensors. If no water or very little makes it, fine then fault. But just complaining about the hot water, my middle finger is restless.
