Is there water in the tub? Or...is the tub empty?
If there is water in the tub you need to check the following:
1. Verify that you do not have a siphon problem. This is caused by placing the drain hose too far into the drain standpipe and/or sealing the top of the standpipe. This will cause water to constantly empty as the tub tries to fill. You need to have an air gap for proper drainage.
2. Check your pressure switch and pressure switch hose.
3. Make sure the drain pump is operating correctly.
4. Check operation of flow meter. This is what actually detects the water flow coming into the machine and causes the error to flash if the proper conditions on are not set. It will detect the AMOUNT of water entering the tub and it detect the pressure switch trip that shuts off the supply when the tub is filled.
If there is no water in the tub you need to check the following:
1. Check your fill valve screens. Turn off the water and remove the hoses from the back of the washer. The fill valve screens are inside the hose connections on the back of the washer. It only takes a small amount of debris to restrict water. You can clean them out using cotton swabs.
2. Make sure your fill hoses are not kinked or clogged.
Check the easy possibilities, first. I suspect you may have either a siphoning problem, or clogged fill valve screens. If you check everything and still have problems, I would replace your fill valve before suspecting a defective pressure switch or flow meter.
Let me know if this helps.

Hi from retired Englishman in SW France,
Whirlpool's 'FH' stands for 'no water inlet' (but goodness knows how 'FH' could mean that!)
If you have checked that the hot and cold water taps are turned on fully and the hoses are not kinked or squashed at the back, it is worth while checking both the hot and cold water inlet filters. Turn the taps off and remove both hoses at the washer end. Inside each inlet port there is normally a little filter which should just slide out. Clean if necessary and replace each one and the hoses. If after turning the taps back on there is no improvement, the problem is symptomatic of a malfunctioning hot or cold water control valve. Sorry but it needs a service call and a check that it isn't the control PCB ;-0(
If this has assisted you please consider a 4 thumbs up for the rating.
Thanks and good luck,
Probably too late, but here it goes:
FH means some cicle is taking too long time.
Replace the inlet electrical valve. It probably wont open enough and the water flow is not enough to fill to level in time. This should cost you 10€ and is easily done by anyone.
Just remove the top of the machine (two bolts on the rear and slide to the back), disconnect the valve (electrical and water input and output), push the lockers and twist the valve free.
if there is none, the water solenoid is the problem,
if there is water going in, then the flow switch is the problem.
here is the transcript from the web..
FH ERROR CODE
No water detected entering machine or Pressure switch trip not detected. If after 30 seconds the control does not detect water entering machine and then valves will be turned off and the error code will be displayed. Or If the control has turned the water valves on and after 8 minutes the flow sensor has detected 48liters of water passing through it, but has not detected the pressure switch trip, the valves will be turned off and the error code will flash.
and here is their solution
water source opened flowmeter pressoswitch wiring to valves, pump, flowmeter, pressoswitch hoses
Okay, ther manufacturer recommends unplugging the washer for at least 30 minutes to reset the computer. It could be you have a momentary glitch causing some problems. If you still have the same problem after leaving the washer unplugged, the following link explains the "FH" error code:
