Question about Dishwashers
My name is Peter. I am a retired field service appliance technician.
You may have unnecessarily replaced the solenoid valve. Did you Ohm it out to see if it was bad?
You may have a bad fill switch or your float is stuck in the up position or a bad float switch.
I can not tell you for sure because you did not provide a model number.

open machine when running and check both spray arms rotating - you will get a bit of water out. if spray arms not rotating, usual cause is debris in the arms. the spray arms only rotate by water jetting from angled jets at the end of the arms. take them out and make sure all debris removed

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.

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.

Follow-up: I was able to fix the problem on Bosch model # SHU 4002UC. Purchased water inlet valve (part number 425458) from Sears Parts Center. I required the Sears unit number from the original invoice as Sears computer system apparently cannot identify the Bosch model number. The valve is as described by meyerjr above; however it is located at the bottom front of the machine so could be replaced (not so easily) without removing the machine. Cost of part was $30.50 Cdn including tax.

When the Dishwasher won't fill you'll need to check for the water inlet hose, the water inlet valve and the float switch assembly. When the water fills your dishwasher, a float rises along with it. As the float reaches a certain threshold level, it shuts off the flow of water, thereby preventing a leak. Sometimes the float can get stuck in the wrong position in your dishwasher, and it can prevent your dishwasher from filling. Sometimes it can happen due to float valve and on other occasions due to float switch. Inspect the water hose coming to the dishwasher for any blockages. If the hose is not clogged then check the water inlet valve for any clogs, if the water will not even fill for few seconds then certainly the water inlet valve is bad and should be replaced. You can also use a multimeter to check continuity on inlet valve. If you don't get any value on the multimeter then you'll need to replace the water inlet valve assembly. However, if the valve is fine then the float switch assembly should be replaced. Hope this helps... Please post back if you need more information.
