SOURCE: E1 error on LG dishwasher
As per my email reply chazmano5, the problem is likely to be the water pump/motor assy.
They have a very common fault of the impeller breaking on the motor shaft. The motor still spins, but the impeller doesn't, so there is no water being pumped.
The machine senses there is no water pressure and shuts down, displaying E1 (eg: it thinks no water pressure means there must be a water leak) Unfortunately the motor/impeller is only available as a complete assembly.

The "FH" error can have several causes, so this can sometimes be a tricky problem to diagnose. Some of these error codes can also be erroneous. The first step to troubleshooting your problem should be to unplug the washer for at least 30 minutes in an attempt to reset the Central Control Unit (CCU). This is the main computer (or brain) of the washer. Sometimes this is all it takes to correct minor glitches. If your error code reappears following a reset, then you know you have a genuine problem. If the "FH" error persists, the following link explains what to do:
Although, you may be correct in your assumption of a possible water inlet valve problem, I would recommend you read through the link provided and try to eliminate the easy things first. Check your installation for a possible siphoning issue, followed by a check of the drain pump. If those items check good, check the sediment screens in the water inlet valve. If you live in an area that has hard water, or if you use well water, the sediment screens can become clogged with deposits and debris. If you suspect a clogged inlet valve you can also remove it and thoroughly clean it in a 50/50 solution of water and distilled vinegar. Allow the inlet valve to soak in the solution for about half an hour and flush real well with clean water. Avoid submerging the solenoids and electrical connections, or getting them wet.
If you have questions along the way, or require additional assistance, please let me know. I hope you find this information helpful.

I had a LG certified repairman come out and fix. The electrical wires within the door were melted into the "tar" (sound deafening spray) and one wire actualy sheered. Apparently the drying cycle heats the tar and the wires become embeded and melt into the tar. This is what was causing the error code. After the wire was tested and spliced everything worked great. Long term...The door/electrical harness was replaced by LG.

SOURCE: ie error code
The Water Supply Tap is closed.
The Water Supply is shut off.
The Inlet Hose is kinked.
The Water Pressure is very low.
(below 10 psi)
Inlet Valve is OK?
The filter of Inlet Valve is clogged
by impure water.
The Hall sensor is OK?
The Impeller of Air Guide is bound
Measure the electric resistance of Inlet Valve. (950-1300 ) Clean the filter of Inlet Valve. Check the frequency of Inlet Water by the Test Mode. Replace the Air Braker.

It is common for these valves to "appear" to be ok, meaning they begin to allow water into the unit, but then one of the two coils or plungers inside fail, or are clogged with mineral deposit from the water or other debris.
Change the valve and you should be fine. part #1164471, you can find it at select parts depots or on-line retailers like repairclinic.com etc.
** Hire a pro or make sure to use a good replacement clamp on the fill line to the tub when you replace the valve, as well as some plumbers puddy/tape on the inlet fitting. Those little buggers have alot of water pressure going thru them when they open and I've seen them come off or leak due to insufficient fastening/loose clamps, then your machine goes into "flood mode".**
Asko seems to be repeating their past. On the earlier DW95 series (mid 90's to around 2000ish) they had a dual valve inlet which had a single valve rework issued to repair the faulty dual valves, now it looks like they're doing it again. Go figure.
Hope that helps, let me know.
Good Luck :)
