I have a LG Diswasher LD 2050 with a trouble Code E1. The manual says "Water leakage in hose connection" "water is leak by damage" Ihave check and everything is Okay. It let water in and when it start about a minute or two the error report and water drain From Johan Crous

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.)
