Read this before you spend money on repairs or parts:
I have a older HE3t washer (from 2000 and still works great!) that was consistently flashing the F/H error code. If I did anything that pushed water (rinse or wash) to the machine 1-2 minutes in to the cycle the code would pop and the washer stop.
i pulled the cold and hot lines at the machine, cleaned the screen traps (which have never been cleaned and were very plugged). The washer is working fine and no more errors codes. Those screen traps impact water flow pressure.
