My whirpool duet washer, one day i found water on the floor and realized that water was coming out of the washer. It was hot water, then put machine into spin and took water out. Then hot water kept coming out. So I closed the hot water faucet and that fixed that problem. Couple days later the washer stops when is into a wash cycle and it gives me the code for FH, which I found out that is no sufficient water. I checked the hose and the water inlet and is clean and there is water pressure. Can anybody help?

Here is your parts breakdown
Model GHW9400PW0

Check the water level switch and the pressure hose attached to it
Make sure the hose is not cracked or brittle and that it fits tightly to the fitting. Item 23 in "Top and cabinet parts" section

If you have not already done so check that there are no dirty filter screens in either the hoses or the water valve (inlet side)
