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.

Maybe the blockage is somewhere else. How about removing all the trays from the dishwasher, in other words, empty it from all racks and dishes and try it again

This is a heater error. The cause is either a bad heating element or bad thermistor (the thermistor is part of the heater assembly). The heater assembly will need to be replaced.

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.)
