Unit has new pressure sensor, clean working pump, clean connection at tub to pressure sensor, good wiring, good pressure hose, clean working water valves, good drain system/stand pipe. Need to know how to narrow and what electrical readings to expect at ccu. what sequence to use at ccu to verify electrical readings. Thanks in advance for any advice.
Have disassembled pump, drained unit, tried a few wash cycles, checked water flow from wall and washer. Tried a diagnostic test but got the F/H error. clean machine with moderate usage and HE detergent used, no suds lock apparent. checked water screens and hoses, drain flow seems strong

OK. I think I have located the correct tech sheet. I had your model as ghw9400plo, which is what you listed. The last digit must be a 1.2.3.4., instead of 0. That changes the tech sheet for the unit. The FH error code includes a lot of possible parts and can be difficult to diagnose. Sounds like you have verified proper drain set up and no siphon issue. I have seen drain pumps that intermittently will not drain and cause this error, but typically you will get a long drain error code as well. Check your flow meter resistance and make sure your pressure hose has no holes and is not clogged. I have seen holes in these pressure hoses as well. If all that checks out good, then you left with the pressure switch or control board. Not a absolute way to test these as far as I know. I would start with the pressure switch first.

Hi. I am not seeing the H/L or the F/H error codes that you have listed in the tech sheet. Please recheck the error codes that you are getting and let me know. I have attached the tech sheet for you as well.

Brian, I used the tech sheet attached under the machine right bottom. DUET HT. Left tech sheet with the machine. It was the first check under troubleshooting and codes on the tech sheet. It had never been out of the plastic bag.

Your tech sheet appears to be a newer tech sheet. let me know what other info I can send you.
