Erin for Model Number GHW9400SUO Hi there. I have a Duet HT with an intermittent F/H error during cycle. Water is entering tub but during fill it stops, drains and flashes the code. I have replaced the pressure switch and it appears that my line (leading to it) is in good/great shape. No signs of leaks ... and I even checked the drain pump to for foreign objects. (There is no problem with it draining) -- -- -- It is intermittent, the F/H code. A few cycles are fine then the next several loads are a fight. -- -- I am running a diagnostic cycle right now. Up to C:05 (the heating... which seems to taking a long time) but no trouble so far. ... Do you think I can rule out everything and go for the Control unit? Or am I missing something?? AND... Everything completed well on the diagnostic run, from what I can tell. Again Thank You.... Erin
Answer Hello Erin. Press PAUSE/CANCEL twice to clear the display. If there is no water in the unit: 1. Make sure that both valves at the water source(s) are turned on all the way. 2. Check for plugged or kinked inlet hoses or plugged screens in the inlet valves 3. Verify inlet valve operation If there is water in the unit: 1. Verify Drain pump operation 2.
