Kenmore He3 and dreaded FH error code

I have a Kenmore Elite He3 washer machine (circa ~2000?) that has stopped working now and is throwing the dreaded FH error code and i was hoping one of you could help me in diagnosing the problem?

CHECKED LIST:

• checked the pump cleanout and made sure it was clear
• replaced the pump motor about two months ago (F9 error), has worked properly since it was replaced (up till now naturally)
• checked and cleaned out the airtrap in the back, it was mostly clean except for a thin layer of dirt
• checked the pressure switch (makes a clicking noise when I blow air through it)
• checked the pressure switch hose for any holes or clogs
• checked the inlet valves for any debris but they were clean
• checked the flowmeter, it was mostly clean except for a thin layer of dirt and spins freely when i blow air through it
• checked for any sort of siphon problem
• checked the drain hose for any clogging problems, it was mostly clean except for a thin layer of dirt

NOTES:

• if i turn on the wash cycle, it will run for about 2-3min b/4 it errors out w an FH error code
• water does fill up in the drum when i first start a cycle
• after the FH error code is thrown, if i power off the machine and attempt to run another cycle w the old water still in the system the washer will pump out some of the water that is already in the system, making me believe the water pump i recently replaced is still working properly.
• when i run the self diagnostic test it only runs for about 1-2min b/4 it errors out on the C:01 error code (flowmeter/cold water inlet valve)

everything i've read on the various forum posts makes me believe the issue is either with the pressure switch or the flowmeter. I haven't seen any posts about a failure on the self diagnostic tests for a C:01, hopefully that will help you narrow it down for me?

I would really appreciate any and all insight you could give me,

thanks!
