Yes there is a way to hard reset it, unplug the unit for 5 full minutes to hard reset it.

Full Reset
Disconnect the power to the Maytag dryer and wait 30 minutes. After 30 minutes, restore power and make a new selection. If the problem persists or the dryer will not operate, disconnect power once again and call Maytag for service.

bad water inlet valve

May be a water pressure sensor problem.
This tells it when the tub is full.

Around 5 gallons per FiLL more then 1 fill per cycle add up all the fills for the cycle that you use..that will give you the total water used...hope I helped thanks for voting...

Hi

Error FH means that a water inlet problem has occurred. 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. Press PAUSE/CANCEL twice to clear the display. If the machine is not filling then check whether both valves at water source are turned ON and inlet hose are not plugged. If the machine is filling fine then chec the pressure switch hose and the drain hose for siphoning (also make sure water is not flowing back to the machine from drain hose). Check wire harness connections to: Inlet Valves, Pressure Switch, Drain Pump, Flow Meter, and Central Control Unit (CCU). Hope this helps... Please post back if you need more information.

I do not think this is normal. This may be a sign that your water fill valve is going bad. I would recommend shutting off your water supply valves when not in use and do not leave unattended when in use in case it gets worse. I would get repaired as soon as possible.

You need to use the HE detergent. I believe that is a drain problem. By using the regular detergent that causes more suds and in turn clogs your drain

check your lid switch if its a top load

ck to be sure drain hose is not more than 6-8 inches in standpipe top of standpile nees to be 30-36 inches above floor and drain hose should be too snug in standpipe ..any of above conditions may result in water siphoning out and not leaving enough water in tub ..washer only uses 5-6 gals per fill based on load so if water is being siphoned out doesn't leave much left
