I have a kenmore washer HE4T model 110 45091 400, and I’m also getting HF error code.
I have already verified drain pump, plugged or kinked hoses, siphon, possible leaks, the water faucets are turned on, and everything is all right.
I changed the flowmeter, Electronic control,Water level switch and another Electronic Control. Changed all, and still not working.
On the image attached put a circle on the parts I have changed. The other electronic control, is the one on the front, where the button are set.
