What does the code fH stand for..we are renting an apartment and they didn't leave the manual

Failure Code - FH

Fault Code Description - No water detected entering machine or Pressure switch trip not detected.

Solution - 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 meter has detected 10.5 gallons 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.

Press PAUSE/CANCEL twice to clear the display.

On most Whirlpool Duet models, you can remove the lower front cover of the washer by removing three torx head screws from the lower lip. Look on the right hand wall, inside the washer. You should find, sealed in plastic, a Diagnostic Guide. It will say do not remove or destroy, for service technician use only. Well guess what, with just a little know how and this guide, you can troubleshoot and repair a lot of your problems. It is not the "owners manual" but has much more info when it comes to troubleshooting or repair. If you need parts, I often use www.repairclinic.com to get appliance parts cheap. It is easy to use. Hope this helps.
