Chosen Solution
I have a Sears Kenmore Elite HE3t Front Loading Washer Made by Whirlpool Model: 110.45966400 I keep getting the F/H Error code. I know the F/H error code has to do with water flow issues, so went through all of the things on everyone’s list of potential problems, and have narrowed it down to this… The hot water valve is not opening to let water in. Sounds like a simple solution, Right? No so much… I replaced the inlet valve, and I have the same problem with the new valve. I opted to switch out the white leads on the hot water solenoid with the black leads on the cold water solenoid. Now the hot water valve opens and the cold valve does not. Okay, so now I’m assuming the problem is not the solenoid on the old or new water inlet valve. Next I checked the wires from the white terminals at the hot water inlet solenoid to the plug at the CCU. Both wires have continuity. Also wiggling the wires and leads while the valve should be open at the beginning of the cycle did not change anything. Okay, so now I’m assuming it’s probably not the wires from the CCU to the hot water side of the solenoid. Now I’m assuming the CCU is bad and not providing power to the wires leading to the solenoid on the hot water inlet valve, so changed out the CCU with a new one. Guess what?! The new CCU provides the exact same result. No power to the solenoid on the hot water inlet. So now I’m sort of assuming the problem is not the CCU either, but I have no idea where to go next? All of the other items for the F/H error code have been checked and either were clean/unobstructed and functioning (pump filter and drain hose are clean and functioning fine to pump out the water from the tub, syphon hose is unobstructed with no kinks or leaks) or were replaced with new (flow meter, pressure switch, inlet valve, CCU). I’m totally perplexed and have no idea where to go from here?
Hi, The manual says that it has an ATC (Auto Temp Control) which is turned ON when a cycle is selected. It controls the flow of hot and cold water into the machine. Looking through all the parts I noticed that there are two control boards parts #3 &15 (click on Control Panel) and the only temp sensor part #26 (click on Tub and Basket) that I could find was on the heater element. Thinking perhaps that the sensor may be faulty and therefore “telling” the control board that the water is hot enough -do not open the hot water solenoid I initially thought perhaps this sensor was only for when the heater element is in use - especially on sanitize washing cycle to heat water to required temp and it is there to disconnect the heater when the temp is reached, but perhaps it has a dual function in that it also monitors the water temp on all cycles. Also I couldn’t locate another temperature sensor. :-) Perhaps you could check that the sensor (if it is the correct one) is OK and if it is, then chase the wiring from the sensor back (if it has any - it may just be inline with the heater wiring) to see which control board it goes to and if it was the one you changed. Just a thought.
Remove the top of the washer, it is a white value control with a sensor attach, remove it and flush with a CLR cleaner. Re install. (let sit for about 3 minutes)
