I found an older thread from 2006 on this problem, but I've tried all the troubleshooting with no results. I get the FH error code approx. 1-2 minutes at the start of a wash cycle. I've checked things mentioned in the earlier thread. The flow meter spins freely. There seem to be no air leaks in the tubing connected to the pressure switch. Should I just go ahead and call the service guy or what else might need replacing with this water inlet problem. Could the pressure switch itself need replacing or the thing that plugs into it with all the black wires coming out of it? Any help is appreciated in trying to avoid a service call.
