E1 display in diswasher

The problem could be the washer motor bearing. LG motors have the impeller unit coupled to the motor and the water seal between the motor and impeller is a problem. The drop of water that leaks ends up on the bearing and it eventually gives problems. This can be seen by close inspection of the front bearing for slight rust indications .They use poor quality bearings but replacing the bearing is easy BUT you need to replace the water seal as this is the cause of the problem. Unfortunately the water seal is part of the plastic impeller unit and must be replaced. Not necessary to replace the whole motor as the bearing is easily replace and cheap. (the noise made by this fault is more of a slightly high pitch grinding / whine)

The IE or 1E error or fault code indicates 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.

Hi

E1 is a leakage error in your LG dishwasher; it is usually displayed either due to a clogged drain or due to water leakage in hose connections. If the drain pump assembly is not clogged then check the motor water seal leakage of sump assembly and also check the impeller of washing pump, if it is worn then replace the impeller. You can also make sure that the height of drain hose is not over 20". Hope this helps...please post back for further assistance.

Hi phtanner,

The E1 error can be fixed by following my Tip below:

L.G DISHWASHER E1 ERROR...

Follow these directions, and the problem will be fixed.

Kind Regards :-)

E1 Leakage error. Cause : water leakage in hose connections. Water is leaked by damages.

my lg door keeps on falling done something wrong with door springs ; how do i repair it.

E1 leakage error
The excessive RPM of Washing Motor happened during Wash cycle due to water leakage.
Water leakage in Hose connections. Water is leaked by damages. The Motor Water Seal leakage of Sump assembly. The height of Drain Hose connection (sink-Drain Hose) is not over 20 . Impeller of the Washing Pump is worn away.
Replace the connections of Hose. Check the point of damages and repair or replace the related parts.
Replace the Impeller of the Washing Pump.

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 main water pump on this model does not last long. The water seal between pump and motor starts to leak that result in the adjacent motor bearing corroding and eventually failing, resulting in excessive noise. Later the water leak becomes so bad that it triggers the "E I" water leakage display and prevents it from completing the program. The pump and motor is sold as one unit and the whole unit must be replaced. I have tried to replace the faulty bearing and repacked the rubber seal with silicon grease but with no success. If anyone have repaired the water seal successfully please let us know.

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
