The 1E error or fault code is to indicate that the washer is not filling with water. Check to be sure the water supply valves are open. Also, check to be sure the water supply hoses aren't kinked or clogged. Next, remove the hoses from the washing machine and run water into a bucket to test the pressure and flow of the water. If all of these check out and you have good water pressure and flow to the machine, you should replace the water inlet valve.
Can you please tell us the exact model of your dishwasher? What you can try initially is unplug the power cable of your unit for about 10 minutes, then plug it back in. See if that clears the error. Will give you follow up about the E1 error.
You have a blockage in the drain line someplace. If you have a garbage disposer, check to see that it is clear where the dishwasher connects to it. Also check and make sure that the drain hose is higher then the inlet to the disposer to prevent water draining back into the drain line from the disposer. If that's clear you have a blockage somewhere in the drainline. Best to unit from cabinet and check it
E1 is a code that the dishwasher displays after detecting a leak. There is a sensor on the pan at the very bottom of the unit. Take the bottom front panel off, look under the unit at the hose coming off the pump and your fill line to be sure no water is dripping. Run the unit in a wash cycle while doing this if possible.

The most common problem on an LG dishwasher when error code E1 is reported but there is no actual leak found is the problem of a natural syphon being created by improper installation of the dishwasher. Pretty easy to fix: Either add an Air Gap valve (available at any hardware store for almost free) or follow the drain hose from the dishwasher to the drain. Raise the hose and attach the hose to the up onto the bottom of the countertop. Adding that "rise" eliminates the possibility for the syphon effect to drain the dishwasher before the drain cycle begins.
If the hose ever fall back down, the problem will return immediately. Adding the Air Gap valve is harder but is far more permanent (and complies with construction codes that really should not be ignored.)
The E1 error is telling you that there is a leak in the dishwasher. After confirming that there is no leak, even directly under the dishwasher (remove the kickplate and use a flashlight.)
After ruling that out, your problem is almost certainly caused by the drain hose between your dishwasher and your drain. There MUST be a 30" rise in the drain hose between the DW and the drain. If the hose just lays there, causing a siphoning effect (law of physics) that WILL drain water out of the dishwasher into the drain as soon as a wash or rinse cycle begins (after 1 - 2 minutes after they begin. Then the E1 error will be displayed.
The BEST way to fix this problem is to install an AirGap valve (almost free @ any hardware store) in your counter/sink and then running the short pipe to your disposal or sing drain inlet. If that is not possible or for a quick and dirty repair until you can install the AirGap, tie the drain hose to the bottom of the counter top so the rise is created.
Please check at both ends of the drain hose and confirm that you do nit have a leak. Also, please confirm that water is not leaking directly under the dishwasher.
If you are certain that you do not have a real leak, check the impeller (under the mesh filter in the sump area beneath the lower dish rack) is not damaged and is firmly in place.
The E1 error code is a Leakage Error, detected by the motor spinning faster than it should if the unit is filled with water.
Please report back with what you find. Good Luck!
90% of the time you get an E1 error code is because the drain hose is not properly installed between the LG dishwasher and the drain. The hose should connect to an Air Gap valve (almost free at any hardware store) but in a pinch, raise the drain hose near the drain and attach the hose to the bottom of the counter top under the sink. Is should rise almost 30 inches between the dishwasher and the drain or the water WILL siphon out of the dishwasher as soon as the wash or rinse cycle begins (and take 5 minutes before the water gets low enough the cause the E1 error.
Well done by resolving this problem. The other way to avoid the siphoning problem through the drain hose is adding an air gap valve/connector (available at any hardware store). You can use it even if you don't have a garbage disposal in your kitchen sink. That will assure that you have the proper height of the drain hose.
Hope this helps!
