SOURCE: E1 error on LG - LD-4120M
E1 is a common error in the LG Dishwasher range and is usually caused by the failure of the circulation pump and/or the impeller.
The motor and impeller are a complete unit.
Often what happens is the impeller breaks on the motor shaft and doesn't spin, therefore doesn't pump water.
There is a pressure sensor which indicates the lack of pressure and shuts the machine down with the E1 error being displayed.
The lack of pressure can also be from a water leak (as the owners manual suggests) also a controller PCB fault may produce an E1 error, however, the pump problem is extremely common.
Unfortunately, I have had 5 pumps die in 4 years and my dishwasher is only used about 4 times a week.

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!

Remove all dish trays from washer, unscrew and remove lid off salt softner, tip machine on side untill all water drains from the salt softner, replace all trays and softner lid and machine should work again.

Try removing all dish trays and salt softner lid, check if the salt softner compartment is full of water, if so place the machine on its side and allow all the water to drain from the compartment, once this is done your machine should be good to go. This is how i resolved my problem. The salt softner is located next to the water drain filter.
