Are you sure it's 1E and not LE error code?? The symptoms you mentioned indicates that it is an LE error code and the motor has an issue. You will need to call a qualified LG technician to diagnose and resolve the problem.

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.

I do not have specific info on your model, as I believe it is one not intended for USA distribution (where I am at) but, you might want to check the following, which applied to some LG dishwashers produced between Jan or 2005 and Feb. or 2007.
The black mastic sound insulation material inside the dishwasher door can soften from the heat inside the dishwasher, allowing the wires inside the door to become embedded in it. If this has happened, the insulation on the wires can soften and begin to dissolve, resulting in shorted or broken wires. This may cause various error codes which may send you on a wild goose chase.
Take the screws out of the door and inspect the black insulation and the wires. If any wires are embedded in the black mastic, you may cut them and bypass them with a new section of wire, then make sure to add an insulating material to separate the wires from contacting the black mastic. In severe cases, the inner door panel must be replaced (they no longer use that type of mastic) and the wiring harness for the dishwasher would also be replaced. (a set of all the wires and plugs).

Try replacing the water inlet solenoid valve (it may have an open coil). The water line goes directly to it.
