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.

SOURCE: LG LD-14AW2 (03 error)
agreed O3 is not a LG error code. OE is more likely and if so it could be the main pcb faulty, a blocked drain pump or a blocked spigot under the sink where the drain hose connects onto.

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.

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!

This happens to my LG dishwasher every 6 months or so. It also makes a groaning sound as if the system is starved for water. I resolve the problem by removing the dishwasher and laying it over on it's right side. I then remove the two plastic assemblies that are on the left side and I remove them from the dishwasher (you will need a vice grips to remove the hose clamps from behind them, you will also need to remove the round circular water intake plastic disk that is on the inside of your dishwasher on the left hand side right in the middle of the left wall) and clean them. Once the water can run freely through these plastic parts you will get a good water flow and you should be fine. Until you have time to do this I recommend putting a few quarts of hot water into your dishwasher once you start to hear the groaning problem. This solution should be very easy for anyone who is comfortable doing their own oil change. Oh, and turn off the power supply first. I think the origin of the problem might be too much food on the plates and too strong of a dishwasher gel detergent so the food is turned into gunk which coats the channels of the plastic assemblies.
