Question about Dishwashers
Won't run gets e1 message
As you said, it is not getting water.
E1 is just the machine telling you this.
A couple of easy ones to check:
1. remove the hose where it screws on to the dishwasher, leave the other end connected to the tap (preferably put the machine end in the sink or a bucket as to not make a mess), and turn on the tap. If the water is not getting through the hose, it may have a faulty water block (flood preventer) on it.
2. If there is water getting through the hose, make sure that the hose is not kinking as you push the dishwasher back in to its hole.
3. If there is water getting through the hose and it is not kinked, and you cannot hear any water going into the machine, you may have a faulty inlet solenoid or control board. Might be cheaper to get someone in to fix it. If you were to guess, I would start with the solenoid, as it would be the far cheaper part.
4. If you do hear water rushing in before you get the E1, then the machine does not know that it is getting water. Could be either a faulty pressure switch or the pressure tube that goes to the switch.
Hope this helps

I had this problem and fixed it tonight. When selecting a program water pumps into the machine, but with no drain i ended up with too much water and error code E6.
I traced the fault to a broken wire between the electronic module in the door and the pump. The point at which the door opens and closes on the cables had frayed the insulation and broken through the wire. As this was the live feed to the pump and a potential short from 240VAC to the chassis its dangerous!!
Repairing the wire break and re-insulating fixed the problem.

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.

Well done by resolving this problem. The other way to avoid the siphoning problem through the drain hose is adding an air gap valve/connector (available at any hardware store). You can use it even if you don't have a garbage disposal in your kitchen sink. That will assure that you have the proper height of the drain hose.
Hope this helps!

The E1error code indicates a water inlet error.
To access test mode: press and hold Normal+Eco, and press Power. Release buttons. Then press Start(display n:01).Press Start again (display shows water level frequency-not important). Press Start again-(display n:03-motor will be running). Press Start again (display n:04-drain pump will run). Press Start again (display n:05-inlet valve will come on and machine should fill with water). You have now tested major components are working-if you keep pressing start you will scroll thru and test other functions, like heater, dispensor etc, but not needed for your fault.
If Machine didn't fill with water in test mode, you probably have a faulty inlet valve (test resistence should be approx 3.7-4 k ohm).
If inlet valve has tested OK ie machine filled with water in test mode then:
Disconnect from power.
Remove side panels (need to remove top, and bottom front panel to then be able to remove sides)
- Check no water in base of machine-water in base will indicate machine has leaked and activated the safety device which shuts off inlet valve.
- If OK, you probably have a faulty flow meter(measures water intake). Located left hand side of machine, large plastic compartment, which has a sensor at the bottom with 3 wires (red,white,black) that go up to control board. Replace entire flow meter assy-relatively inexpensive part.
- If you still have problem, then control board is faulty, it is much more likely to be flow meter .
